Abstract
The utility model discloses a malodorous gas treatment device for a municipal solid waste treatment plant. The malodorous gas treatment device is applied to treating malodorous gas generated in the municipal solid waste treatment plant. The device consists of a biological filtering area and an activated carbon adsorption area. The malodorous gas in the municipal solid waste treatment plant is uniformly distributed through a gas distribution plate and enters a biological filtering unit, and an absorption and biodegradation reaction is carried out in the biological filtering unit. The air discharged out of the biological filtering unit is conveyed through a gas conveying pipe and enters the activated carbon adsorption area, the malodorous gas is adsorbed through activated carbon fibers and activated carbon particles, and tail gas is emitted through a discharge outlet at the bottom of the biological filtering unit. The malodorous gas treatment device for the municipal solid waste treatment plant in the utility model is good in treatment effect, small in occupied area and low in investment and operating cost and has wide utilization prospects.
Description
Affiliated technical field
The utility model relates to a kind of urban garbage disposal factory foul gas processing unit, and the foul gas processing producing for garbage processing procedures such as the comprehensive sorting of domestic waste, compost and landfills, belongs to environmental protection technical field.
Background technology
In the comprehensive sorting of domestic waste, compost and landfill disposal process, can produce the foul gas that main component is hydrogen sulfide, thio-alcohol, ammonia and VOC.The foul gas threshold concentration that domestic waste factory produces is low, and e-quipment and pipe is had to strong corrosion, also can cause interference to normal production and periphery resident's daily life, produces serious health and ecological environment harm.
Technology development for urban garbage disposal factory foul gas mainly comprises absorption and sorption, catalysis, burning and plasma technique etc.In recent years, biologic treating technique particularly bio-filter technology because equipment is simple, treatment effeciency is high, investment and the advantage such as operating cost is low, non-secondary pollution, be applied to gradually the processing of gases containing stench sulphureous gases.But because the gases containing stench sulphureous gases relative concentration producing in oil, chemical industry and petrifaction sewage processing procedure is higher, except containing hydrogen sulfide, ammonia and VOC, also may contain methyl mercaptan, ethyl mercaptan and ethyl sulfide material, composition is complicated.The acidic materials that particularly produce in sulfur-bearing, ammonia gas biodegradation process easily cause system pH to reduce, thereby cause the reduction of system treatment effeciency.Visible, conventional biological treatment device when processing urban garbage disposal factory gases containing stench sulphureous gases, exist treatment effeciency low, be difficult to realize the drawbacks such as qualified discharge, system fluctuation of service.
Summary of the invention
Low in order to overcome existing urban garbage disposal factory foul gas processing unit treatment effeciency, be difficult to realize the deficiencies such as qualified discharge, system fluctuation of service, the utility model provides a kind of urban garbage disposal factory foul gas processing unit, this treating apparatus is simple in structure, floor space is little, can realize the qualified discharge of domestic waste factory foul gas.
The utility model solves the technical scheme that its technical problem adopts: a kind of urban garbage disposal factory foul gas processing unit, is comprised of biofiltration unit and activated carbon adsorption unit.First urban garbage disposal factory foul gas enters in the biofiltration unit of filling haydite, sponge Double layer high efficient active bio filler after gas distribution grid is uniformly distributed, and bio-absorbable and bio-degradation reactions occur.The double-layer active biologic packing material of filling in biofiltration unit is haydite and polyurethane sponge piece, haydite layer and polyurethane sponge layer separate by porous barrier, two-layer volume ratio is 1:1, and wherein the particle diameter of haydite is 1.0-3.0mm, and the particle diameter of polyurethane sponge piece is 3.0-5.0mm.Give vent to anger and enter activated carbon adsorption unit after air shooter carried in biofiltration unit, foul gas is after the absorption of active carbon fibre peacekeeping activated carbon granule, and tail gas is through being arranged on the exhaust outlet discharge of biofiltration unit bottom.
The beneficial effects of the utility model are, have adopted advanced materialization-high-performance bio combined treatment technology, can be efficiently, stable, process urban garbage disposal factory foul gas fast.Apparatus structure is simple, compact, and treatment effect is good, non-secondary pollution deposits yields, and investment and operating cost are low.

The specific embodiment
In Fig. 1, a kind of urban garbage disposal factory foul gas processing unit, comprises biofiltration unit (4) and activated carbon adsorption unit (9).Foul gas enters before biofiltration unit, first passes through evenly gas distribution of gas distribution grid (2).The inner double-layer active biologic packing material (5) of filling in biofiltration unit, in active filler, inoculate High Efficient Bacteria and fungi complex microorganism, top, biofiltration unit arranges nutrient solution shower (6) and nutrient solution spray head (7).In activated carbon adsorption unit (9), fill NACF (10) and activated carbon granule (11), bottom arranges exhaust outlet (12).
First urban garbage disposal factory foul gas enters biofiltration unit after gas distribution grid is uniformly distributed, and bio-absorbable and bio-degradation reactions occur in biofiltration unit.Give vent to anger and enter activated carbon adsorption unit after air shooter carried in biofiltration unit, foul gas is after the absorption of active carbon fibre peacekeeping activated carbon granule, and tail gas is through being arranged on the exhaust outlet discharge of biofiltration unit bottom.
Claims (2)
1. a urban garbage disposal factory foul gas processing unit, it is characterized in that: by biofiltration unit and activated carbon adsorption unit, formed, first urban garbage disposal factory foul gas enters filling haydite after gas distribution grid is uniformly distributed, in the biofiltration unit of sponge Double layer high efficient active bio filler, there is bio-absorbable and bio-degradation reactions, give vent to anger and enter activated carbon adsorption unit after air shooter carried in biofiltration unit, foul gas is after the absorption of active carbon fibre peacekeeping activated carbon granule, tail gas is through being arranged on the exhaust outlet discharge of biofiltration unit bottom.
2. a kind of urban garbage disposal according to claim 1 factory foul gas processing unit, it is characterized in that: the double-layer active biologic packing material of filling in biofiltration unit is haydite and polyurethane sponge piece, haydite layer and polyurethane sponge layer separate by porous barrier, two-layer volume ratio is 1:1, wherein the particle diameter of haydite is 1.0-3.0mm, and the particle diameter of polyurethane sponge piece is 3.0-5.0mm.
