Description
Technical field:
The present invention relates to technical field of sewage treatment equipment, particularly a kind of equipment that utilizes micro-wave energy to dispose of sewage.
Background technology
Along with the reinforcement of human society production and economic activity, human unreasonable development and use cause environmental quality constantly to worsen.Water pollution, water quality deterioration have aggravated water globe shortage of resources situation.Worsen and the short water supply problem in order to alleviate environmental quality, for a long time, people are devoted to the development research of sewage disposal technology always.Develop so far, sewage disposal technology can roughly be divided into physics method, chemical method, physico-chemical process and biochemical process four classes.Yet these treatment processs all have certain limitation, on application conditions and treatment effect, there is very big defective, just has as accounting for the sewage biochemical treatment process market dominant position, technology maturation (as activated sludge process, oxidation ditch etc.) at present that floor space is big, investment is big, the construction time is long, water quality and quantity fluctuation bad adaptability, operational and administrative expenses height, be subject to shortcoming such as weather condition restriction.The development of serious restriction sewage disposal cause.Be directed to this, people have proposed a kind of novel sewage disposal technology---microwave sewage disposal technology.
The microwave sewage disposal technology has changed traditional sewage disposal mode, makes sewage water treatment method become effectively simple more.Its principle is summarized as follows: the polar molecule in the sewage (containing the water molecules that accounts for the sewage overwhelming majority) produces violent orientation movement (as the microwave of frequency of utilization 2450MHz in the microwave electromagnetic field of high speed alternation, this orientation movement is to carry out at a high speed with 24.5 hundred million times/second frequency), each polar contaminants molecule, nonpolar contaminant molecule high-speed motion actively or passively all in this violent big sports system, all more or less micro-wave energy is converted to the interior energy of contaminant molecule, make its activation energy reduction and play an active part in various physics, chemical reaction, make the reaction that originally can not carry out become and to carry out, make sluggish reaction originally become quick, even the material that does not originally possess catalysis is become some reaction has been had catalysis or the like, also can make the bacterium in the sewage, its space structure of pathogenic agent changes or destroys, protein denaturation, thereby lose biological activity, also can change its biological arrangement polymerization state and characteristics of motion thereof, and microwave field induced ionic current, can influence near the charge distribution of cytolemma, cause the barrier action of film to sustain damage, influence the function of Na-K pump, produce the film dysfunction, thereby disturb or destroy the eubolism function of cell, cause bacterial growth to suppress, stop or dead, moreover the Yeast Nucleic Acid in the cell (RNA) and thymus nucleic acid (DNA) can cause the loose of key under the effect of microwave field power, fracture or reorganization.Modificator gene sudden change or chromosome aberration influence its bioactive change, delay or interrupt the genetic stability and the propagation of cell.Thereby sewage is purified.
The research of microwave sewage disposal technology just began from eighties of last century eighties, because it is to the peculiar function of sewage disposal and tempting development prospect, research to it has in recent years formed upsurge, many technical solutions have appearred around it, the CN1231213A that publishes as Chinese patent, CN101143737A, CN201033739Y, CN201024097Y or the like has certain representativeness, but a common ground is arranged all, promptly " microwave apparatus for treating sewage " is that the microwave Sewage treatment systems is requisite, the equipment of total technical characterictic is the key of microwave Sewage treatment systems.
The microwave apparatus for treating sewage is made up of wave source (containing the adjustable Controlling System of output rating), microwave resonator and microwave apparatus for treating sewage core three parts.
Wherein most of patent documentation custom with the very sophisticated already microwave wave source of technology (containing the adjustable control section of microwave power) and standardized microwave short range delivery element (waveguide and flange) in addition big length describe, this is sophisticated, total technical characterictic in fact, and people only need bring with getting final product.
CN1231213A document representative in numerous patent documentations passes to the water quench resonator cavity with design one cooling jacket outside the resonator cavity of sewage disposal specialty industrial microwave oven.This design may be suitable in other fluid handling except that sewage, but in the microwave sewage disposal, there is no need, because in microwave field sewage be purified be polar molecule in the sewage in the microwave electromagnetic field of high speed alternation fierce orientation movement, micro-wave energy is converted to the interior energy of contaminant molecule in the sewage, its energy level is raise, be in utmost point unsteady state and play an active part in various physics, chemical reaction and sewage is purified, do not obtain by heating sewage, practical situation confirm, large amount of sewage (as: time treatment capacity be 100m
3) when the 20kw microwave field its temperature rise very little, do not exist resonator cavity to need the refrigerative problem.
And for example form simple helix shape microwave apparatus for treating sewage core with flexible corrugated tube coiling in the CN1231213A document, solve its fixation problem with the mode that clamping plate are tied up, rope is hung.In sewage treatment project, the sewage of big flow, high loading must make its unstability, come off when the processing core of this structure flows through, and the wall of corrugated tube characteristic thin, inner wall coarse own has a strong impact on the security of sewage treatment process.
And for example the CN101143737A document has been released a kind of multi-layer spiral core of vertical placement, its sewage advances, water outlet all is in the bottom of this multi-layer spiral core, see the accompanying drawing 2 of the document, when sewage passes through in microwave field, owing in this course various chemical reactions can take place, be bound to produce gas, if microwave apparatus for treating sewage core is the multi-layer spiral core of above-mentioned vertical placement, the gas ratio liquid light, gas definitely can be in the highest point of multi-layer spiral core pipeline, and can not flow with the effluent stream easy on and off, and it is stifled and stop up flowing of effluent stream only can to form ducted gas, the gas that blocks up section when gas constantly is compressed, and pipeline also has the danger of explosion.
And for example said in the summary of the invention of CN101143737A " technical problem to be solved by this invention is to propose a kind of microwave resonator that improves the microwave penetration ability in sewage disposal ", in fact, no matter design which kind of microwave resonator, can not improve the microwave penetration ability, because to a kind of fixed medium (as a certain sewage), the penetrativity of microwave is a certain value, can not change, the guiding theory that therefore designs a kind of preferable microwave resonator should be towards increasing microwave field strength in the unit volume, improving the direction of microwave utilization ratio works hard.
And for example the CN201033739Y document is described, adopts many small power magnetrons, realizes the adjustable of power input; As sewage disposal, in general, the little Summer Solstice or the Winter Solstice of its processing power handles the hundreds of big Summer Solstice or the Winter Solstice of ton and handles 1,000,000 tons, if all adopt the small power magnetron to regulate its output rating, is possible in the laboratory, and is just inadvisable to bigger sewage disposal project.According to market survey, the magnetron production status of China is: the magnetron of frequency 915MHz has only 20kw's, high power valve up also is in the development stage, low power tube does not down also form series, abroad have and greatly arrive 100kw, but price is very expensive, according to consulting, the 100kw magnetron price that Germany makes is 100,000 Euros, is beyond affordability.The magnetron peak power of frequency 2450MHz is 10kw, and low power tube has down become series product, and that select for use as household microwave oven is 1kw.Be used in that magnetron that the wave source of sewage treatment area uses generally selects 915MHz, 20kw for use with 2450MHz, 10kw, also realize already as for the continuously adjustable Controlling System of power.Therefore too little concerning sewage disposal with the microwave wave source of 1kw or several kw, be inapplicable.Therefore, a kind of microwave apparatus for treating sewage of the present invention designs with regard to being based on two kinds of wave sources of 915MHz-20kw and 2450MHz-10kw.
From above-mentioned background technology document as seen, although many treaters occurred at present, be that the theoretical basis of design or the specific design scheme of releasing are all not fully up to expectations.
