Background technology
In recent years, with the rapid growth of wastewater treatment in China ability, sludge yield is synchronously significantly increased.At sewage
The end product of reason, sludge contains the poisonous and harmful substances such as substantial amounts of pathogen, heavy metal and persistent organism, according to statistics mesh
Preceding sludge of the whole nation more than 80% does not obtain innoxious, stabilization processes disposal, causes secondary environmental pollution situation very tight
Weight.For this problem, in recent years, country puts into effect a series of relevant policies for being related to specific resistance to filtration, standard and method law
Rule, have promoted the formation in market.
Municipal sewage sludge is handled and the principle of disposal is：Minimizing, innoxious, stabilisation, recycling, " minimizing "
" innoxious " is the emphasis of sludge treatment, and " recycling " is the final goal of sludge treatment.For effective, thorough solution sludge
Problem of environmental pollution, by substantial amounts of waste can be changed into working substance by technological development, sludge is comprehensively utilized, obtain
Good economic benefit and environmental benefit.At present, sludge anhydration burning technology the developed country such as American-European-Japanese obtained into
Work(application, as a kind of main sludge treating method.
Sludge incineration is that dewatered sludge is sent directly into incinerator the combustible component in sludge is fully burnt at high temperature,
Poisonous and harmful substance in waste in high temperature oxidative pyrolysis and be destroyed, eventually become stable lime-ash.Sludge incineration is " most
Mud thoroughly ", it can make organic matter all carbonizations, effectively kill pathogen, sludge body is reduced to greatest extent
Product, and floor space is small, and automatization level is high, is not influenceed by external condition.High with volume reduction, weight-loss ratio, processing speed is fast,
It is innoxious more thoroughly, waste heat can be used for generate electricity, heat supply or for sludge drying provide needs thermal source the advantages of.
The independent incineration disposal method of traditional sludge uses air as oxidant, causes gas pollutant（Such as NOx, SOx
Deng）The Transport And Transformation of, dioxin emissions and heavy metal is relatively uncontrollable, is puzzlement sludge incineration secondary pollution processing cost
High key issue.Traditional sludge incineration technology is difficult to be used on a large scale in China in a short time, and only East Coastal part is sent out at present
Sludge incineration technique is employed up to the city such as city such as Guangzhou, Shanghai.Therefore, seek a kind of collection to control oneself burning, resource reclaim, low
The sludge cleaning incineration disposal technology that disposal of pollutants is integrated is considerable in future market prospect.
《Chemical industry is in progress》In the 4th the 713-725 pages of the phases of volume 31 in 2012, a kind of basic skill of burning chemistry chains is elaborated
