Description

A composite making method using both organic waste and sludge and the composite made by IEC}

The present invention relates to an organic waste, and more particularly, to a method for producing a decomposed soil by mixing food waste, sewage or agricultural waste, etc. with fermentation adsorbents having improved water purification sludge, and a decomposed soil produced by the manufacturing method thereof. .

It is known that the annual amount of garbage generated in Korea is about 30 million tons, of which food waste, which is organic waste, accounts for about 25.4%, and about 0.25kg of food waste per person per day is thrown away. Only about 33% of this food waste is recycled and the rest is disposed of by landfill or incineration, which translates into 10 trillion won in total, and 13 trillion won in total, including landfill costs, environmental recovery costs, and landfill maintenance costs. It is estimated to exceed.

Food wastes spilled about 30,000 tons per day cause secondary environmental pollution and odors caused by leachate if left untreated, and its disposal is a very important environmental issue. It is becoming.

Representative methods of treating food waste include a pyrolysis method of incineration in an incinerator, a method of embedding at a predetermined site, and a method of recycling by feed or composting.

The most realistic and highly applicable method of treating the food waste can be referred to as a composting method, which can be roughly divided into aerobic fermentation method and anaerobic fermentation method.

First, in the composting method by anaerobic fermentation, since organic substances in food waste are used as a substrate of anaerobic microorganisms and finally recycled to an energy source such as methane gas, the composting method shows a higher decomposition rate of organic matter than aerobic fermentation. As long as the fermentation period is long, most anaerobic methane-producing bacteria show optimal growth at neutral pH at medium temperature, so food wastes with a pH of 4-5 should be calibrated before input. Methane gas, which is very sensitive to this external environment (especially the presence of oxygen as a poison to the microorganisms) and the end product, is highly explosive and requires high technology for its operation, maintenance and safety management operations. There is a problem that the initial investment and maintenance of the facility will have to cost a considerable amount.

On the other hand, in the conventional composting method by aerobic fermentation to adjust the water content by adding a moisture control material such as sawdust or chaff to food waste, and then stirring or blowing in consideration of the characteristics of the microorganisms that require oxygen for growth. Oxygen is supplied, and fermentation proceeds at a temperature of 45-80 ° C., which is a relatively high temperature growth condition, generally 55-60 ° C., by heat of fermentation (substrate oxidation heat), and shows good characteristics in maturity and water content. .

However, the sawdust or chaff, etc. act as a moisture control agent, but when it is finally composted and made into decomposed soil, it does not decompose, causing problems in the utilization of decomposed soil.

The present invention is to solve the problems of the conventional composting method and to provide a method for producing decomposed soil using anaerobic and aerobic methods for organic waste, that is, food waste, sewage or agricultural waste.

In particular, the present invention is to significantly improve the disadvantage that the additives such as sawdust, chaff and the like used as the moisture control agent is not significantly decomposed to provide a method for producing loess soil using organic waste.

In particular, the present invention is to provide a technique for recycling the waste by providing a method for producing the submerged soil by innovative use of waste sewage or water purification plant sludge.

In another aspect, the present invention is to provide a method for providing a boiled soil pursuing the convenience of the process by innovatively improving the very difficult air providing method in the operation of the pulp process.

In another aspect, the present invention is to provide a complete waste treatment method by providing a method for perfecting the dehydration filtrate treatment, which is a problem of composting the conventional food waste, and mixing and recycling it in a maturation process.

In order to solve the above problems,

Process of crushing organic wastes (step 1), process of dehydrating organic wastes from crushing process (2 steps), process of mixing dehydration residues and functional additives of organic wastes undergoing dehydration process (3 steps) ), The first step of fermenting the mixed fermentation raw materials of the three steps (step 4), and the step of second fermentation of the fermentation raw material (secondary fermentation raw material) of the first step of the fourth step (step 5) It provides a method for producing a made up soil.

In addition, the present invention is the process of crushing the organic waste (step 1), the process of dewatering the crushed organic waste and the process of anaerobic digestion of the dehydration filtrate to produce the digested sludge (step 2), the dehydration process of the organic waste Process of mixing dehydration residue, functional additives and the digested sludge as fermentation raw material (3 steps), process of first fermenting the mixed fermentation materials of the 3 steps (4 steps), primary fermentation of the 4 steps Provided is a method for producing a decomposed soil comprising a step of fermenting fermented raw material (secondary fermented raw material) to secondary fermentation (5 steps).

In another aspect, the present invention provides a method for producing a decomposed soil, characterized in that the fourth step is carried out by aerobic or breathable fermentation process, the fifth step is carried out by aerobic agitation bogie.

In another aspect, the present invention provides a decomposed soil prepared by the above production method.

Since the process of producing pulp soil according to the present invention does not use sawdust and rice husk at all as a moisture control agent, it shows the effect of suppressing anaerobicization due to high water content in the early stage of pulp processing and improving breathability to produce stable pulp soil.

In particular, the present invention is used to remove the odor generated during the fermentation process by using the adsorbent using the water purification plant sludge which is a functional additive of the present invention, not only acts as an excipient but also can minimize the deodorizer.

The present invention has the effect of achieving complete reuse of waste by dehydrating organic waste, especially food waste and anaerobic digestion of its dehydration to minimize volume and using digested sludge as a mixture of the fermentation process.

In addition, the fermentation apparatus used in the primary fermentation process in the present invention has the effect of maximizing the effect of the air supply by installing a plurality of air discharge pipe due to the air distribution pipe in contact with the air supply means.

In addition, the present invention is carried out by the stirring bogie maturation process used in the secondary fermentation process exhibits the effect of producing the optimum maturity soil.

Hereinafter, the present invention will be described in detail.

The present invention is a fermentation raw material by mixing the dehydration residue and functional additives of the organic waste, such as food waste, sewage or concentrated agricultural waste, the process of crushing the organic waste, the process of dewatering the crushed organic waste, the dehydration process It provides a method for producing into a pulp soil by using the organic waste through the process, the first fermentation of the mixed fermentation raw material, the second fermentation of the fermentation raw material first fermented.

In another aspect, the present invention provides a decomposed soil prepared by the above-mentioned decomposed soil manufacturing method.

The present invention performs a process for crushing the organic waste, such as food waste, sewage or agricultural product waste.

In the present invention, the crushing and sorting of organic waste means that the organic waste is crushed to a certain size by a device such as a crusher or a crusher.

The crushing of organic waste to a certain size means that the user can freely select and crush it in a form suitable for fermentation according to the characteristics of the organic waste. Therefore, the crushed size is about 1 ~ 50mm in size can be varied according to the user's choice.

In addition, sorting means the process of removing undecomposed components mixed in organic waste.

Therefore, components that cannot be decomposed or difficult to decompose, such as plastic, iron, and other wood, are removed artificially or through a sorting machine. In this case, it is possible to remove and sort foreign matters using a conventional foreign matter sorter using physical force such as natural dropping force, gravity, magnetic force, wind power, and electric force.

In the present invention, the process of crushing and screening the organic waste means that crushing the organic waste and then sorting the foreign matter, or first screening the foreign matter and crushing the organic waste, or including both the process of crushing and screening at the same time It should be understood as a concept.

The present invention performs the process of dehydration after performing the process of crushing the organic waste described above.

Dehydration means a process that lowers the water content of the crushed organic waste.

 Conventional food waste has a water content of about 83 to 90% and is usually about 87%. Therefore, the food waste is dehydrated using a dehydrator at a water content of about 73 to 77% and more preferably about 75%.

The organic waste thus dehydrated is called dehydration residue.

In addition, the dehydration filtrate dehydrated in the above dehydration step is about 88 ~ 92% of the water content and is usually about 90%.

Therefore, the dehydrator used in the dehydration process in the present invention is dewatered to the extent that the dehydration rate of the organic waste dehydration residue is maintained using a conventional dehydrator.

The dehydration filtrate is very high in organic matter content is digested using a digestion tank to be used in the process of manufacturing the pulp soil of the present invention or treated by a general waste treatment method.

In the present invention, it is preferable to use the anaerobic digestion method as described above for the dehydration solution. The reason for this is that the dehydration liquid has a very high organic content, so it is more effective to use anaerobic digestion rather than aerobic digestion.

The present invention has a great technical feature in that it is possible to carry out the process of mixing the digested sludge produced by anaerobic digestion treatment with the dehydration residue as described above to be introduced into the fermentation apparatus as described below.

The present invention has a great technical feature in mixing the dehydration residue and the functional additives into the fermentation apparatus.

As mentioned above, in the conventional method of composting (waste soiling) organic waste, sawdust, chaff, etc. are generally mixed to control the moisture content to maintain an effective and proper fermentation process.

However, the sawdust, chaff, etc., the main component is composed of a polymer cellulose component was almost impossible to decompose. Such non-degradable sawdust, rice husks, etc. have caused a problem of significantly lowering the quality of the pulp soil finally provided.

The present invention completely solves the above problems, and the functional additives are mixed with the dehydration residue and added to the fermentation apparatus for fermentation.

The functional additive of the present invention corresponds to a porous material and can be usefully used as long as it has a hygroscopic and adsorbent function such as an adsorbent or a deodorant.

Therefore, when the functional additive used in the present invention is mixed and fermented with the dehydration residue, the fermentation process not only creates the effect of removing moisture, but also removes the role of excipients and odors from the fermentation process. As it is maintained, it shows an excellent effect in the production of pus soil.

The present invention performs a process of mixing the dehydration residues obtained through the dehydration process and the functional additives described above.

The mixing of the dehydration residue and the functional additive in the mixing step is preferably mixed to maintain the moisture content of 65% to more preferably 63 to 67%.

Mixing while maintaining this moisture content significantly increases the fermentation efficiency in the next fermentation process.

For example, as described above, in the case of food waste, the water content of the dehydration residue is about 73 to 77%, and the water content of the functional additive is about 10 to 15%.

Therefore, the degree of mixing of the dehydration residue and the functional additive of the food waste may mix 5 to 25 parts by weight of the functional additive to 100 parts by weight of the dehydration residue.

In the present invention, the dehydration residue and the functional additives are mixed as described above, and the first fermentation process is carried out as a primary fermentation material.

The present invention also mixes the digested sludge produced through the anaerobic digestion process with respect to the dehydrated filtrate of the organic waste together with the above-mentioned dehydration residue and functional additives as the primary fermentation material and enters the primary fermentation process. can do.

Anaerobic digestion of the present invention means a method for treating conventional high concentration organic wastewater.

Anaerobic digestion, therefore, means that anaerobic bacteria ingest and reduce organic matter in high concentration organic wastewater and release useless inorganic compounds.

There are three stages to this decomposition: acidic fermenter, acidic reducer and alkaline fermenter. In an acidic fermenter, hydrocarbons are mainly decomposed by the action of anaerobic bacteria, and in an acidic reducer, organic acids and nitrogen compounds are decomposed. Finally, in alkaline fermenters, most of the remaining organic matter is decomposed to generate carbon dioxide gas or methane gas, to produce digested sludge and to stabilize it. In addition, a method of reducing digestion time by performing rapid digestion by an excellent species microorganism without going through an acid reducer is also proposed.

In addition, the influence factors of anaerobic digestion include PH, temperature, toxic substances and the like, which can be operated by the driver according to the conventional anaerobic digester operation method according to the properties of the dehydrated filtrate of the organic waste of the present invention.

In general, anaerobic digestion is a high temperature, medium temperature, low temperature digestion in Korea, mainly in the medium temperature digestion. Anaerobic digestion takes about 15 to 60 days.

In this way, the anaerobic digester withdraws the digested sludge, so that the water content of about 73 ~ 77%, preferably about 75% water content can be mixed with the functional additive in the dehydration residue to be introduced into the fermentation process.

In the present invention, the mixing of the dehydration residue, the functional additives and the digested sludge in the mixing process is preferably mixed so as to maintain the moisture content of 65% to more preferably maintain the moisture content of 63 to 67%.

Mixing while maintaining this moisture content significantly increases the fermentation efficiency in the next fermentation process.

For example, in the case of food waste, the water content of the dehydrated residue is about 73 to 77%, the water content of the functional additive is about 10 to 15%, and the digested sludge is maintained at 73 to 77%.

Therefore, when the food waste is treated, the mixing degree may be mixed with 5 to 35 parts by weight of functional additives and 5 to 40 parts by weight of digested sludge to 100 parts by weight of dehydrated residue.

The present invention has the effect of recycling as decomposed soil by reforming the dehydrated filtrate after anaerobic digestion to digested sludge again. This creates the effect that almost all of the organic waste is recycled to the loam soil.

In addition, the present invention is a fermentation raw material of the above mixture is introduced into the fermentation apparatus to perform a primary fermentation process.

The primary fermentation process of the present invention may utilize a conventional aerobic, anaerobic or breathable fermentation process, more preferably it is efficient to aerobic or breathable digestion.

In the present invention, the aerobic fermentation process means a process of decomposing and maturing the organic material as a fermentation material using aerobic microorganisms.

When the oxidation reaction of the organic material by the normal aerobic microorganism occurs, the temperature rises due to the reaction heat, and the proliferation of thermophilic bacteria is active, so the larvae and eggs of the pathogenic microorganisms and pests that are weak to heat are killed.

In addition, when the substrate of thermophilic microorganism decreases, actinomycetes, fungi, yeasts, and mesophilic microorganisms in general soils proliferate, producing polyphenolic compounds as metabolites. Polyphenolic compounds are polyphenoloxidases in the air. Hydrogen peroxide (H 2 O 2) is produced as it is oxidized to quinone compound by the catalytic reaction of) and hydrogen peroxide reacts with microbial enzyme to produce oxidase. Quinone compounds are matured by converting them into non-volatile stable humic substances by polycondensation with lignin, cellulose, tannin, etc., which are difficult to be degraded by microorganisms.

Corrosive microorganisms include actinomycetes, Bacillus mycoides, bacillus, Sorangium cellulosum, Myxobacteria, and fungi (Aspergillus niger, Penicillium sp). , Mucor sp., Fusarium sp.), And these microorganisms are known as corrosive microorganisms that convert polyorganic substances from their metabolites to convert organic substances into corrosive substances.

In addition, in order for the corrosion reaction to proceed smoothly, the reaction by the oxidase polyphenol oxidase must be smooth.

Microorganisms such as filamentous fungus and Pseudomonas sp. Ingest the corroded corrosive as a substrate to promote growth such as vitamins and auxins, which are physiologically active substances useful for plant growth among metabolites. Excrete the substance;

The caustic finally reacts with the active minerals (water soluble minerals) in the coarse minerals of the soil to form a colloidal micelle in the form of a chelate caustic mineral complex. It may also be Sat.

Therefore, in order to produce high quality decomposed soil from organic waste such as food waste, corrosive microorganisms (such as actinomycetes, Bacillus mycoides, Sorangium cellulosum, Myxobacteria), which convert organic substances into stable corrosive substances, as mentioned in the biological reaction mechanisms described above. , Aspergillus niger, Penicillium sp., Mucor sp., Fusarium sp.…, Etc.) and useful soil microorganisms (Pseudomonas sp. Bear, bear

It is possible to produce high quality pulp soil only by carrying out the housing treatment process while maintaining the growth environment conditions such as fungi, yeasts (Torura sp., Mycotorula sp.,) And nitrogen-fixed fungi in optimal condition.

Therefore, the C / N ratio of the early stage of the housing process is important, and the progress of the maturation process is a change in temperature, pH, moisture content, C / N ratio, organic matter content, and salt concentration.

In conclusion, the most important factors in the process of home cooking by aerobic fermentation of food waste are the proper control of moisture content of food waste in the pretreatment stage, the proper air supply and the proper agitation in the fermentation stage. The smooth supply of air in this way is one of the most essential and essential operating conditions for the purpose of supplying sufficient oxygen into the reaction substrate, reducing the water content by evaporation of water, and controlling the temperature.

Fermentation methods by aerobic fermentation include a low speed fermentation method and a high speed fermentation method, and the present invention can use both of these methods.

The fast fermentation method usually uses a batch type fermenter, which is equipped with a stirrer or is self-rotating and has a forced aeration means and a temperature control means, and has a relatively short fermentation period compared to a slow fermentation method. There is an advantage.

Slow fermentation methods exist, but there are a variety of fermentation structures, but typically, for example, by installing an air supply pipe at the bottom, then covering the sawdust, rice husk, etc. on the top, and stirring several times a day. Although it has a low installation cost and is suitable for mass production, it can not be tolerated by the generation of ammonia gas and sulfur dioxide gas by the growth of facultative anaerobics or anaerobics when the oxygen supply is not locally smooth. Degree of stench and anaerobic feet

There is a concern that leachate by hyo may occur, and the fermentation aging takes a relatively long fermentation period of 40 days to 3 months, and a large amount of sawdust or chaff as a moisture control agent. However, the present invention solves the above problems because the fermented by mixing the functional additive of the present invention instead of sawdust or chaff as described above.

The present invention is a fermentation material made by mixing the dehydration residue and the above-mentioned functional additives and / or dehydration filtrate anaerobic digestion sludge from the dehydration process as described above will be very excellent in preventing the water content reduction by the above water evaporation Boasts the effect.

Therefore, in the present invention, the primary fermentation process is efficiently carried out even if the fermentation process is performed using a conventional fermentation apparatus. In the present invention, the first fermentation process may take about 7 to 20 days, which may vary depending on the nature of the organic waste.

The present invention can also improve the efficiency of the fermentation process using a fermentation apparatus developed by the present inventors as a primary fermentation apparatus used in the primary fermentation process.
