Description
Technical field
The utility model relates to the innoxious minimizing real time processing system of a kind of sewage sludge.
Background technology
Sewage sludge is the international difficult problem in the sewage disposal, also is insoluble residual contamination source in the sewage disposal, and is very big to the harm of environment.Processing basic demand to sewage sludge is: realize the innoxious of mud, minimizing reaches 50% above decrement degree.
The at present domestic sewage sludge processing mode that generally adopts has three kinds, promptly burns after compost, the mummification after landfill, the mummification after the mummification.
Contain a large amount of moisture in the mud, general sludge moisture content is not less than 80%, comprising free-water, organic-biological cellularstructure water, organism colloid water and molecular water, conventional dehydration means comprise centrifuge dehydration, filter press, seasoning etc., can only take off free-water wherein, realize mud decrement about 30% even lower.A large amount of moisture is present in the mud organic matter with forms such as colloid water, molecular water, cellularstructure water, the mud landfill or the compost of this mummification, because of causing the reaction of mud generation anaerobically fermenting about the anerobe in wet environment and the mud, discharge hydrogen sulfide, organic sulfide, indoles, aldehyde, ketone kind more than totally 200 produce malodorous material, the severe contamination atmosphere, wherein kind belongs to carcinogens more than 20.And can add stench and peculiar smell because of the corrupt substance that produces in the composting process, and cause mosquito, fly parasitism, become the prevailing disease carrier, influence environmental health and publilc health.In addition, compost also produces methane, has hidden peril of explosion.In addition, compost fermentation sterilization degree is low, and hypopus of the harmful bacterium in the compost body (gemma) and heat-resisting pathogenic bacterium all grow in a large number, can accumulate a large amount of toxin and can produce secondary pollution to environment, harm people's life safety.Because active organic matter has been consumed by the long-term metabolism Decomposition of microorganism, the organic matter that compost obtains is the nonactive organic matter of humic acids.Inorganic content height in the compost can destroy the physical structure in the soil.
The sludge anhydration burning mode had appearred again in recent years, mud process filter press or centrifuge dehydration earlier, enter in the stoving oven then and dry, deviate from 40% above moisture, realize the mummification of mud, send in the incinerator then and burn, also need to carry out about 4 days anaerobically fermenting before the burning to improve the calorific value of dewatered sludge.This processing mode energy consumption superelevation, the initial furnace temperature that causes more greatly adding behind the mud because of material moisture in the sludge incineration is lower, be easy to generate obnoxious flavoures such as Dioxins, also can't eliminate heavy metal and toxicity in the mud, to the not reduction of damaging effect of environment.
So every sludge treatment technology of present domestic application can not satisfy, and the sewage sludge processing is innoxious, the requirement of minimizing, has great application limitation.China at present year disposes of sewage 440---and 56,000,000,000 tons, produce the mud total amount per year and be about more than 4,000 ten thousand tons, if can not reliable treatments mud, will bring serious secondary pollution to environment, threatening environment safety and human health.
The processing of sewage sludge is with minimizing and harmlessly turn to basic demand, and realize that minimizing and innoxious effective means are exactly to finish organic oxidative degradation fast, the organic small organic molecule that all is degraded to the Stable Carbon element structure, eliminate cellularstructure water, colloid water and molecular water in the mud, eliminate the fermentation function of sewage sludge.
