Description
Technical field
The invention belongs to the purified treatment field of waste gas, be specifically related to processing method and the treating apparatus of the cacodorous industrial tail gas of a kind of high-temperature high humility tool.
Background technology
In recent years, under national energy-saving reduction of discharging and pro-active fiscal policy effect, town sewage processing is developed rapidly, and Urban Water environmental improvement obtains remarkable effect.But must see a large amount of mud disposal that is not also generally effectively addressed that town sewage processing procedure produces.These mud are very easy to underground water, soil etc. to cause secondary pollution, become the threat of Environmental security and public health, affect the good effect of national energy-saving reduction of discharging strategy implementation.Therefore, Treatment of Sludge is disposed the important content reducing discharging as China cities and towns, must adopt an effective measure, and implementing of Push Technology and engineering measure, meets the general requirement of China's energy-saving and emission-reduction strategy implementation conscientiously.
Urban wastewater treatment firm mud is the product of sewage disposal, is mainly derived from the process procedure such as primary sedimentation pond, secondary sedimentation tank.Every ten thousand m3 sewage after treatment sludge creation amount (by moisture content 80%) are generally about 5 ~ 10 t, and concrete output depends on the factors such as draining system, influent quality, sewage and sludge treatment technique.Wherein, the moisture content of primary sludge is generally 97% ~ 98%; The moisture content of activated sludge is generally 99.2% ~ 99.8%; Mud is after concentrating, and moisture content is generally 94% ~ 96%; After dehydration, can make moisture content be reduced to 80% left and right.Moisture content refers to the quality of contained humidity in mud and the ratio of sludge quality.
Developed country is through the development of decades, and Treatment of Sludge disposal technology route is relatively ripe, and relevant laws and regulations and standard criterion are fairly perfect.Sludge treatment initial major way in Europe is landfill and soil utilization.Since twentieth century nineties, can be fewer and feweri for the place of landfill, the pressure that Treatment of Sludge is disposed is increasing, European construction large quantities of sludge anhydration burning facilities.Due to sludge anhydration burning investment and operating cost higher, in while mud, harmful components gradually reduce again, and the utilization of mud soil is come into one's own again, become the important selection of sludge treatment scheme.In recent years total trend be soil utilize ratio more and more higher, European Union and most European countries more and more support the soil utilization of mud.At present, the annual mud (dry weight) producing of Germany, Britain and France is respectively 2,200,000 t, 1,200,000 t and 850,000 t, has reached respectively 40%, 60% and 60% as the ratio of agricultural direction soil utilization.Although north America region land resource abundance, sanitary landfills is totally less, the technology path that Treatment of Sludge is disposed be always agricultural be main, and done a large amount of safety evaluatio work for agricultural sludge.At present, in 16000 sewage treatment plants' annual output 7100000 t mud (dry weight) of the U.S., approximately 60% is processed into biosolids through anaerobic digestion or aerobic fermentation, is used as farmland fertilizer.In addition, have 17% landfill, 20% burns, 3% covering recovering for mine.Japanese due to soil restriction, the main technological route that Treatment of Sludge is disposed is that after burning, building materials are utilized as master, and agricultural and landfill is auxiliary.In recent years, Japan starts to adjust original technology path, more focuses on the living beings utilization of mud, gradually reduces the ratio of burning.
To sum up, American-European countries's clearer and more definite major way using soil utilization as sludge treatment and encourage direction at present.Soil utilization mainly comprises three aspects: the one, and agricultural as crops, pasture lawn groom; The 2nd, use as the woods of forest land, afforestation fertilizer; The 3rd, as the soil improvement of sandy bare land, salt-soda soil, abandoned mine improvement matrix.Due to the objective factor such as transportation range, operation easier, agricultural sludge amount is used and soil improvement far above woods again.In addition, America and Europe generally adopts anaerobic digestion and aerobic fermentation technology to carry out stabilisation and harmless treatment to mud.Wherein more than 50% mud has all passed through Anaerobic Digestion.The U.S. has also built the aerobic fermentation of cover more than 700 treatment facility in addition.The anaerobic digestion of mud or aerobic fermentation are the soil utilization of mud, especially agriculturally provide good basis.
Along with improving constantly of China's town sewage handling rate, urban wastewater treatment firm sludge yield also sharply increases.2009,1992 of the urban wastewater treatment firms putting into operation in the whole nation, the amount of disposing of sewage 28,000,000,000 m3, mud approximately 2,005 ten thousand t of generation moisture content 80%.Along with the increase of the level of urbanization and sewage load, sludge quantity will be broken through 3,000 ten thousand t very soon.According to incompletely statistics, current national urban wastewater treatment firm mud only has fraction to carry out sanitary landfills, soil utilization, burning and building materials utilization etc., and major part is not carried out normalized processing disposal.Mud contains the poisonous and harmful substances such as pathogen, heavy metal and persistent organism, without effectively processing and dispose, very easily underground water, soil etc. are caused to secondary pollution, directly threatening environment safety and public health, reduce the environmental benefit of sewage treatment facility greatly.
The technical team that inventor leads from the autumn in 2008 just in Changzhou, Jiangsu Province Zheng Lu sewage treatment plant, invest more than 300 ten thousand yuan, a set of sewage plant sludge charcoal processing has been processed in independent design, the reuse of charcoal calory burning, the fully-automatic equipment of furnace slag brick making lignin-sludge---sludge of sewage treatment plant drying equipment, installation and debugging are produced normal, within 24 hours, constantly move and process 12 tons of mud.
In sludge of sewage treatment plant processing policy, sludge drying treatment technology has been a kind of safe and reliable processing mode by approval, and operating cost is cheap, easy and simple to handle.The Treatment of Sludge thing that utilizes this technology to produce, can be used as cement raw material, brickmaking raw material, foundation engineering filler and refuse landfill overburden soil etc.In the mummification and processing disposal process of mud, former pollutant kind and the form being present in mud changes, and transfers to gas phase from solid phase, thereby formed the waste odour-gas body of a large amount of high temperature, high humidity, stench, high concentration.Main matter in these waste odour-gas bodies is hydrogen sulfide, methyl mercaptan, ethyl mercaptan, toluene, dimethylbenzene, methyl disulfide and ammonia etc., wherein hydrogen sulfide and ammonia etc. are the compositions that is easy to become solution in water, hydrogen sulfide etc. are sour gas, and methyl mercaptan, ethyl mercaptan, toluene, dimethylbenzene and diformazan second-rate etc. be VOC gas, ammonias etc. are alkaline gas.Directly be discharged in atmosphere if these foul gas are not treated, meeting heavily polluted area environment and air quality, cause serious harm to human body and ecological environment.
And the fact is also, the general operation of sludge of sewage treatment plant drying equipment in changzhou about ten days, near chemical plant boss arrives, common people complain chemical plant to produce and produce smell gas, through checking and verify, we do not have, and are originally your Treatment of Sludge, you lose no time to process, otherwise have not produced.So the independent research of inventor team has designed the equipment of a set of water-soluble tail gas, applicant country lives and builds the evaluation of portion's scientific technological advance center, and technical feasibility is domestically leading, after application, will produce good social benefit and environmental benefit, also applied for patent of invention simultaneously, the Chinese invention patent application Publication Specification that can be 201010000238.6 referring to application number: adopt haydite to be stacked among a fixing scope, top water filling or shower water, below draining, form cooling turriform utensil, utilize time and speed and water-soluble appearance principle, by house refuse or city sludge drying and other treatment, charing processing, the tail gas producing in burning disposal production process is introduced exhaust decentralized system in utensil through water washing emission gases (foul smell), gas ejection nature is distributed in utensil, in utensil, gas is fled with porosity, contact molten appearance is condensed under water heavy outflow and returns to sewage treatment plant again with water.
