Abstract
A multi-section high-efficient malodorous biological gas purification plant consists of at least two connected pools with a gas passage respectively. A gas redistributor is arranged at the lower part of each pool to distribute the gas and support materal filling, with the gas passage and a filler leachate outlet arranged at the bottom. The leachate outlet is connected with a water collecting tank. A layer of biological filler consisted of the organic filler and buffer substance covers the gas redistributor. Compared with the prior art, the plant has the advantages of simple structure, material availability, low manufacturing and use cost, low energy consumption, and convenient assembly and disassembly of the plant and filler change.
Description
Technical field
The utility model relates to a kind of device that foul gas is carried out the biological cleaning processing, more particularly, relate to a kind of processing, can be applicable to the processing of the foul gas that places such as city domestic sewage treatment plant, municipal wastewater pump house, sludge treatment and livestock and poultry farm produce materials such as low concentration foul gas such as hydrogen sulfide, ammonia, trimethylamine, mercaptan.
Background technology
In recent years, people's the bad consciousness of protecting strengthens day by day, and is more and more higher to the prescription of living environment.Simultaneously, environmental administration has proposed stricter requirement to the discharging and the improvement of foul gas.In the past, people have proposed the biological treatment of foul gas through long term studies.Can be used at present administering the foul gas that produces in wastewater treatment, sludge treatment and the industrial processes, mainly contain chemical method, physics method and bioanalysis.Materilization freatment method is regenerated and the last handling process complexity after the secondary pollution because of there being the various and complex process of device therefor, and energy consumption is big, so fail to be applied always.
Summary of the invention
The purpose of this utility model is to overcome the deficiency of above-mentioned existence, especially overcome the shortcoming on the materialization treatment technology, provide that a kind of process equipment is simple, to administer and maintain convenience, less energy consumption, operating cost low, and the high efficient foul gas biological purification plant of multisection type of removal efficient.
The purpose of this utility model is finished by following technical solution, it has the cell body of gas passage to link to each other respectively by two-stage nitration to constitute at least, every section cell body bottom is provided with the gas redistributor, the gas redistributor plays gas distribution and supports filler, the bottom is provided with gas passage and the outlet of filler percolate, and the percolate outlet is connected to water leg by connecting control valve; Be filled with the biologic packing material layer of forming by organic filler and the mixing of buffering material on gas redistributor upper berth.
Described cell body is in series mutually, biologic packing material layer segmentation filling, and be provided with gas passage between every section filler, adjacent pool body and function flange connects, and is convenient to dismounting, maintenance and changes filler.
The top of described biologic packing material layer is provided with water injector, and water spray is in order to keep the moisture content of filler, to keep activation of microorganism, is equipped with heat-insulation layer in the outer periphery of cell body.
Be respectively arranged with air inlet and gas outlet on described every section cell body, and link to each other with gas passage respectively.
Be provided with the pH probe in the described water leg.
Device of the present utility model can be divided into two kinds of forms according to the flow direction of gas and spray liquid: reverse-flow and parallel type.Multisection type also can be grouped at the different different fillers of packing section filling according to the one-tenth of handling gas, and a large amount of microorganisms of the organic filler of adopting in device energy enrichment need not to spray nutritive salt; Can also adopt parallel as required for gas-liquid counter current formula device.Air inlet pipe is located at the top of device, the waste gas that desire is handled enters the organic filler layer by air inlet pipe, through physical chemistry and action of microorganisms in the filler, make the odorant in the gas be removed or transform, can reach respectively more than 99% and 95% the removal efficient of hydrogen sulfide and ammonia.Purified gas is discharged from the air vent at device top, and reaches national stench discharge standard.
Humidity in the biofiltration device is to keep by shower water, the moisture content of filler should keep about 60%, the too high meeting of moisture content causes in the device that pressure drop increases, energy consumption increases; Moisture content is low excessively, can reduce activation of microorganism, causes the removal decrease in efficiency of device.Install 20-30 ℃ that interior temperature should be controlled, activation of microorganism reduction on the filler, the removal decrease in efficiency of all can making too high or too low for temperature.In order to make the temperature in the device keep stable, heat-insulation layer can be set at the device skin.The pH of percolate in the pH probe monitoring water leg, the ruuning situation of understanding filler.
This utility model compared with prior art has the following advantages:
1. simple in structure, material is easy to get, manufacturing, use cost are cheap, energy consumption is low;
2. biofiltration device is installed in series by the multistage cell body and forms, and filler also segmentation is installed, and every section cell body connects by flange, is convenient to the replacing of combination, dismounting and the filler of device;
3. multisection type also can be grouped at the different different fillers of packing section filling according to the one-tenth of handling gas;
4. the biofilter material active area of organic filler and buffering material mixing composition is big, treatment effeciency is high;
5. organic filler and buffering material mix the easy enriched microorganism of forming of biofilter material, are convenient to adhering to, grow, breeding of microorganism, and degradation capability is strong, effective, and need not to spray nutritive salt.
