Sludge condensation, dehydration and drying, transhipment, heat drying, compost in treatment facility and sludge handling process etc..Different places
Reason facility and process can produce a variety of foul gas.The main foul smell of the inlet water lifting pumps house property life of sewage treatment plant
For volatile organic matter VOC in hydrogen sulfide and sewage raw water etc., what is produced in first clarifier sludge anaerobic digestion process is smelly
Gas is based on hydrogen sulfide and other compounds containing reduced sulphur (dimethyl sulfide, dimethyl disulfide, mercaptan), and sludge and digestion are steady
Foul smell during ammonia and other effumability organic pollutants (VOC) sludge aerobic compost can be produced during fixed then
With ammonia and dust (compost later stage) for main pollutant component；Sludge air drying process is led there may be minimal amount of hydrogen sulfide
There are mercaptan and two print base sulphur gases to produce, in addition some volatility organic aliphatic acid.In a word, in sewage and sludge
During place is buried, the foul smell composition distributed is all the synthesis of various pollutants, species up to hundreds of, composition also becomes
It is indefinite to change.
The processing method of foul smell has a lot, there is burning method, absorption method, biological treatment, ion method, masking method, dilution method
Etc. a variety of methods, generally require to carry out different selections according to different situations.According to《Urban wastewater treatment firm Odor control
Technical regulation》Listed, for urban wastewater treatment firm, the method for adaptation mainly has bioanalysis, ion method, active carbon adsorption
And masking method.In above method, biological odor removal method is first elected.
Biological odor removal method exhaustive division, is divided into biological, biofiltration and the class of zinc cation three.Code is respectively to these three
Method has carried out simple definition:Biology be using it is porous, than table, the big inert inorganic material of product makees filler, foul smell passes through
Packing layer of the surface with microorganism, odorant is through mass transfer and biodegradable removed process.Biofiltration is using tree
The organic substances such as leaf, bark, wood chip, soil, peat make filler, foul smell packing layer with microorganism, stench by table
Material is through mass transfer and biodegradable removed process.Zinc cation is that foul smell passes through with zinc cation liquid in absorption tower progress
There are a large amount of microorganisms in gas-liquid contact, cleaning solution, odorant enters zinc cation liquid through mass transfer, then in biological respinse
Biodegradable process in device.
But occurring taking up an area existing biological deodorizing device more be not reduced, the not undiminished situation of operating cost, most
Important treatment effeciency is not very high.Therefore provide that a kind of can to take up an area few low biological deodorizing device of operating cost again be ten
Divide necessary.
It is an advantage of the invention that rational carry out air water distribution to biological deodorizing device, it is easy to efficient removal foul smell,
It is easy to qualified discharge.Played simultaneously in the efficiency that biological deodorizing can be further improved to foul smell progress humidification.
The content of the invention
It is an object of the invention to provide a kind of modified biological deodorizing device, its advantage is rational to biological deodorizing dress
Progress air water distribution is put, is easy to efficient removal foul smell, is easy to qualified discharge.It can enter in foul smell progress humidification simultaneously
The efficiency that one step improves biological deodorizing is played.
The present invention above-mentioned technical purpose technical scheme is that：A kind of modified biological deodorizing
Device, including air inlet area, treatment region, exhaust area, inhalant region, catchment, the treatment region include water dispensing board, water inlet spray
Shower pipe, biologic packing material, manhole.Enter the upper end that water sprayer tube is located at the treatment region；Biologic packing material is located at the treatment region
Middle-end；Air inlet area is located at the lower end air inlet for the treatment of region；Exhaust area is located at the upper end for the treatment of region, is easy to easy to exhaust.
By above-mentioned technical proposal, with odorous H2S and NH3- N gas enters treatment region from the lower end for the treatment of region,
The biologic packing material for sequentially passing through each layer carries out biochemical deodorization, and purified gas is discharged from the top for the treatment of region.Spray liquid is from entering
Water pipe enters shower, is uniformly sprayed by distributing hole on biologic packing material, and suitable external rings are provided for microorganism growth
Border, has adsorbed the pollutant (H in foul smell2S and NH3- N) spray liquid pass through microorganism degraded step by step, then pass through processing
The catchment drainpipe of area lower end is expelled to sewage treatment facility, proceeds the degraded of pollutant.
The present invention is further arranged to：Described manhole is located at each layer of water dispensing board, and easy access is used.
By above-mentioned technical proposal, every layer of biologic packing material can in time be investigated, be carried conscientiously for microorganism growth
For ensureing, whole system is set to continue normal operation.
The present invention is further arranged to：The water dispensing board includes water distribution cap.
Pass through above-mentioned technical proposal, it is possible to achieve stable water distribution, it is short to avoid spray liquid from occurring during descending
The phenomenons such as stream, so as to ensure the abundant contact of gas-liquid.
The present invention is further arranged to：Described inhalant region includes distribution pipe, diffuser, is humidified beneficial to foul smell.
By above-mentioned technical proposal, foul smell can be humidified in advance, enter rapid in biologic packing material to improve foul smell
It is degraded by microorganisms, so as to improve the degradation efficiency of foul smell.
In summary, the invention has the advantages that：
1st, the rational air water distribution for reaching biological deodorizing, improves the efficiency for removing foul smell, is easy to qualified discharge, carries
