A kind of novel biological deodorization tank
Technical field
The utility model relates to a kind of novel biological deodorization tank, and especially a kind of deodorizing filter tank that utilizes warming solar energy belongs to the biological deodorizing field.
Background technology
Plane formula biological deodorizing filter tank technique is simple, and cost of equipment is lower, energy consumption is little, management maintenance is convenient, is widely used in industries such as sewage disposal, organic fertilizer production.It is higher relatively that but the biological deodorizing filter tank technique requires environment temperature, in the winter time, northern area particularly, temperature is lower than subzero for a long time, and common biological deodorizing filtering pond is owing to be subjected to temperature and influence deodorizing effect and obviously descend.
The utility model content
In order to address the above problem, the utility model has designed and a kind ofly can reduce the influence of temperature to the biofilter deodorizing effect, and cost be low in the biological deodorizing filter tank, modified plane of northern area whole year operation, and is easy to maintenance.
Bioanalysis is to utilize microorganism with the organic pollutant degradation in the odorous gas or be converted into the process of harmless or low harmful class material.Compare with other physico-chemical process, handle the waste gas small investment with bioanalysis, operating cost is low, and pollutant can not be transferred to other place, does not produce secondary pollution.
The foul smell compound mainly is hydrogen sulfide and organic gas, upwards flows and passes the biofilter filled media, and temporarily be adsorbed on surface, duct, microbial cell table
In face or the pellicular zone, these pellicular zones are formed on particle surface and bacterium surface.Before being absorbed by microorganism, the foul smell molecule is assigned with repeatedly between air and filter body medium.After being absorbed by microorganism, organic gas participates in microbial metabolism, and under the adapt circumstance condition, be attached to microorganism on the biologic packing material and utilize pollutant in the waste gas as the energy, the activity that earns a bare living, and it is decomposed into CO
2, H
2O and other inorganic salts, thus waste gas is purified.These production by biological are in the locality, and in local environment ubiquity.The medium of biofilter provides oxygen, moisture and mineral nutrition composition for microorganism carries out metabolism.
In the northern area of China, particularly extreme severe cold area, winter temperature is lower, underground frozen soil layer can reach more than one meter, the filtrate of ground tabular form or open type biofilter is because temperature influence, the physical behavior of filtrate and biochemical condition can change, for example porosity change, microbial activities reduction etc., and these variations make filter tank odor removal efficient difference or can not move at all.Adopt the design of buried daylight type greenhouse heat-insulating, keep the biofilter not influenced by ambient temperature, can annual normal operation.
The technical solution of the utility model is: a kind of novel biological deodorization tank, comprise at the bottom of biofilter material, filter tank wall and the filter tank, the top in described deodorizing filter tank is coated with top cover, the part of described filter tank wall locates below ground level, described top cover adopts the insulation ceiling structure, and the ventilation facility is installed on the top cover, and the filter tank wall is a wall body structure, can be coated with insulation material, the top cover outside, inboard covering insulation material.
Foul smell is through the pressue device pressurization, after entering into the dust-separating appliance dust-separating, gas enters into the bottom of deodorization tank, disperse to enter into biofilter material and carry out biofiltration, and make gas in biofilter material, carry out circulating filtration by the leacheate EGR, gas after the filtration is discharged into the space on deodorization tank upper strata at last, and discharges by the ventilation facility.
Advantage of the present utility model is: adopt the buried biological deodorizing of this kind filter tank, can obviously improve under the winter low temperature situation, the operational effect of biofilter can annually normally be moved the biofilter.
