The improvement deodourization device of soil
Technical field:
The present invention relates to a kind of foul smell treating apparatus.
Background technology:
The geobiont deodoration system is a high activity, the vigorous ecosystem, because of its moisture holding capacity and metastable biocoene system with appropriateness, therefore foul smell is had purified treatment effect preferably; Other has advantages such as device fabrication is simple, maintenance management is convenient, is favored by domestic and international expert always.But its geobiont deodoration system is because of the characteristics of its structure and filler self, and the phenomenon that hardens, hardens can appear in gas permeability variation after operation a period of time.In order to overcome the possibility that easily hardens, disadvantages such as poor durability prevent soil hardening, must once turn in several years and nurse one's health, and as adding certain amount of calcined lime, adjust pH.
Biotrickling filter is the place of microbial degradation gas organic pollution, also is up-to-date deodorization process equipment.Microbial adhesion, be fixed on the inertia high efficiency packing, specific area is big, and the microbial adhesion face is many, and micro organism quantity is many, and gas is also many by the chance that packing layer contacts with microorganism.Biotrickling filter is not only the place of biological deodorizing, also is simultaneously the place of growth of microorganism breeding.The temperature that growth of microorganism need suit, humidity and acid-base value condition also will have sufficient oxygen and nutriment.In Biotrickling filter, can build the control environment of growth of microorganism, simultaneously the oxygen oxygen supply of the foul smell that sucks by air blast by effective control.The needed nutrient of microorganism is carbon, nitrogen, phosphorus.Organic matter in the waste gas also has elements such as carbon, nitrogen, phosphorus, can satisfy the growth of microorganism needs generally speaking, an amount of again element that is lacked that adds of needs when lacking element such as carbon, nitrogen, phosphorus when the organic matter in the waste gas.
Summary of the invention:
The object of the present invention is to provide a kind of rational in infrastructure, take up an area of little, the improvement deodourization device of soil of good deodorization effect.
Technical solution of the present invention is:
A kind of improvement deodourization device of soil, it is characterized in that: housing is arranged, dress filter material layer in the housing, the filter material layer below is provided with carriage, and the filter material layer upper surface is provided with the water distributor of circulation water-distributing device, and the housing inner bottom part communicates with the circulation water-distributing device, the support filter material layer is set on the water distributor, the soil filter material layer is set on the support filter material layer,, gas distribution pipe is set in the carriage lower portion.
Filter material layer is the filter material layer or the composite filter material layer that forms of the filtrate of different specific areas of bigger serface.Vegetable layer is set on the soil horizon.On vegetable layer top water injector is set.The filtrate of bigger serface is multiaspect hollow ball filler or three-dimensional column cavity filling.The filtrate of bigger serface, its specific area that can adhere to for biomembrane is 300~800m
2/ m
3The support filter material layer is granular filter material layer and/or filter layer of cloth.Housing is the housing of concrete shell or metal, plastics, pmma material.Housing bottom is gradient form, helps catchmenting.At housing bottom heater is set, the water of housing bottom is heated, heat the winter that is fit to cold district.
The present invention is rational in infrastructure, and floor space is little, has only 1/5~1/4 of normal soil method, and can be arranged on subsurface, half subsurface, the first-class different places of building, combines the advantage of traditional soil method and Biotrickling filter deodorizing, the deodorizing effect excellence.
Description of drawings:
The invention will be further described below in conjunction with drawings and Examples.
Accompanying drawing is the configuration diagram of one embodiment of the invention.
The specific embodiment:
A kind of improvement deodourization device of soil, housing 1 is arranged, dress filter material layer 2 in the housing 1, filter material layer 2 belows are provided with carriage 3, and filter material layer 2 upper surfaces are provided with the water distributor 4 of circulation water-distributing device, and housing 1 inner bottom part communicates with the circulation water-distributing device, support filter material layer 5 is set on the water distributor 4, soil filter material layer 6 is set on the support filter material layer 5,, gas distribution pipe 7 is set in carriage 3 lower portion.Vegetable layer 8 is set on the soil filter material layer 6, water injector 9 is set on vegetable layer 8 tops.Housing 1 bottom is gradient form, helps catchmenting and the compiling of impurity.At housing bottom heater 12 is set, the water of housing bottom is heated, heat the winter that is fit to cold district.
Filter material layer 2 is filter material layer or composite filter material layers that form of the filtrate of different specific areas of bigger serface.The filtrate of bigger serface is multiaspect hollow ball filler or three-dimensional column cavity filling.The filtrate of bigger serface, its specific area that can adhere to for biomembrane is 300~800m
2/ m
3Support filter material layer 5 is granular filter material layer 10 and filter layer of cloth 11 (also can be granular filter material layer 10 or filter layer of cloth 11).Housing 1 is the housing of concrete shell or metal, plastics, pmma material.
The course of work of the present invention is: the gas that needs deodorizing to handle enters in the housing through gas distribution pipe 7, through the filter material layer 2 of bigger serface, and through the water spray processing, enters in the atmosphere with 8 one-tenth clean gas of vegetable layer through soil filter material layer 6.
