Description
Technical field
The utility model relates to exhaust gas treatment technology, specifically, relates to a kind of simple in structurely, and deodorizing effect is better, is used for removing the waste gas biological deodorizing clarifier of the odoring substance that sewage and sludge handling process produce.
Background technology
Along with the in-depth of municipal sewage treatment degree and the raising of handling rate, the output of sludge of sewage treatment plant progressively increases progressively, and the deodorizing problem of sludge of sewage treatment plant is just causing increasing concern.In order to prevent and eliminate in municipal sewage plant and the Treatment of Sludge disposal process foul gas to the influence of surrounding environment and resident living; Develop effective odor treatment technology and treatment facility and seem very necessary; The same with sewage disposal; The processing method of stink has a lot, but economical and practical also genus biological deodorizing is technological.
Biological deodorizing is a kind of deodorization technology of developing in the 5O age in 20th century, is developed rapidly at beginning of the nineties late 1980s, and develops into the main flow of deodorization technology gradually.Main biological treating equipment has: biological washer, biofilter, bio-trickling filter.What research was more at present is biological filter process and bio-trickling method.The biological filter process processing procedure is to be adsorbed and absorbed the foul smell in the stench air-flow by natural filtering material, comes oxidative degradation by the bacterium that is grown in the filtrate with other microorganism then.Usually adopt wood chip, bark etc. in traditional biofilter as filler.The advantage of biological filter process is simple, and investment and operating cost are few; Sulphur-containing exhaust gas treatment effeciency for high flow rate light concentration is high; Basically there is not or has only a spot of secondary pollution etc.But the gaseous substrate concentration Gao Shihui that the biofilter exists, and floor space is big, rotting appears in long-time running, the filter material layer resistance increases, treatment effeciency reduces, contain pollutant causes biomass to increase too fast and stops up filler, the filter bed volume is big, exhaust gas residence time long and upgrades problem such as trouble of filler.The bio-trickling filter method is the biological deodorizing technology that combines biofilter and biological kitchen sink, and it is to contain the gas process of pollutant or without preliminary treatment, get into bio-trickling filter.The advantage of bio-trickling filter method is simple, flexible design; Investment and operating cost are low; PH and temperature are easy to control; Particularly handle halogenated hydrocarbons, sulfur-bearing, nitrogenous etc. when producing the bigger pollutant of acidic metabolite and production capacity through the microbial degradation meeting, efficient can effectively be handled mass concentration and reach 500g/m than higher
3H
2S gas.But the dissolving of waste gas odor causing substance is a rate-limiting step in this treatment system, must let gas that the sufficiently long time of staying is arranged, thereby needs the circulation fluid filter bed that continues to flow; If can not effectively control the consumption and the nutritional labeling concentration of circulation fluid, it is not smooth that the surface area that the microorganism excessive buildup can reduce filter bed and effective volume cause stopping up air-flow, thereby cause the pressure drop increase; Reduce and remove efficient; On the other hand, possible microbial film undergrowth influences treatment effect.
The utility model content
To above deficiency; It is a kind of simple in structure that the utility model provides, and deodorizing effect is better, is used for removing the waste gas biological deodorizing clarifier of the odoring substance that sewage and sludge handling process produce; It comprises the casing that is formed with air inlet and air outlet; Be provided with clarifier in the said casing, said air inlet is positioned at the left plate of casing, and said air outlet is positioned at the right plate of casing.
Said clarifier comprises that several piece is arranged at the filler longitudinally in the casing, and filler is spaced apart from left to right, extends out to the inwall of said casing around each said filler, and each said filler is with biomembrane.
Each said filler adopts porous ester class material to process.
The left side of each said filler is respectively equipped with several shower nozzles towards this filler, is provided with the aqueduct that connects all shower nozzles of conducting in the casing, and the bottom of casing is formed with several apopores.
The below of said casing is provided with the cistern that communicates with each said apopore respectively, and the water pump of the water in the cistern being delivered to each shower nozzle also is installed on the casing.
Said cistern is provided with flowmeter.
The bottom of said cistern is formed with the floss hole of the product discharge that microorganism is decomposed.
The beneficial effect of the utility model: the utility model adopts porous ester class material to do filler, easy to be filmed, ageing-resistant, resistance is little, physical life reaches 3～5 years; In addition, casing adopts a left side to advance the turnover wind mode that the right side goes out, and helps reducing resistance; Have, depth of packing in the past adopts the mode of horizontal shop more than 500mm again; Resistance is big, and the filler easy blocking is aging, rotten; Depth of packing after the optimization is below 50mm, and the utility model adopts perpendicular mode of hanging, and helps reducing resistance on the one hand; Help the collection of aging biofilm detachment on the other hand, can not stop up filler, simplified internal structure simultaneously; At last, the utility model is realized the water circulation use in the casing through water pump and cistern, and economical environment-protective, and can monitor the water yield in the cistern at any time through flowmeter is prevented the sealing excessive bleed and influenced deodorizing effect.
