Technical field
A kind of sewage-treatment plant is the utility model is related to, it is more particularly to a kind of to be used for city sewage and sludge and trade effluent The high dewatered sludge degree dehydration reducing device of sludge dewatering decrement.
Background technology
Substantial amounts of sludge can be produced during municipal sewage treatment and Industrial Waste Water Treatments.For municipal sewage treatment, With the development of domestic sewage disposal cause, sewage plant total process water yield and degree for the treatment of constantly will expand and improve, caused Sludge quantity also increasingly increases, and its capital construction and operating cost account for total capital construction and operating cost in general sewage plant at home at present 20%~50%.In sewage sludge except containing the nutriment such as substantial amounts of organic matter and abundant nitrogen, phosphorus, also exist heavy metal, The poisonous and harmful element such as pathogenic bacteria and parasite.The numeral provided according to State Environmental Protection Administration, the at present annual about discharge of China are dirty There are more than 400 seats, the m3 of daily handling ability 25,340,000 in the m3 of water 40,100,000,000, the municipal sewage plant for being completed operating.By sludge yield Account for the 0.3% ~ 0.5% of processing water(In terms of moisture content 97%)Calculate, the yield of Chinese city sewage plant sludge is in 7.602 ten thousand m Between 3/d and 12.67 ten thousand m3/d (in terms of moisture content 97%).Secondary pollution caused by prevent sludge and guarantee sewage disposal The normal operation and treatment effect of factory, the position that the processing handling problems of sewage sludge are occupied in sewage disposal are increasingly prominent Go out.
Present circumstances is seen that the core of Treatment of Sludge and difficult point are dewatering technology of mud.Due to China's sludge dewatering technology Fall behind, cause the moisture percentage in sewage sludge more up to 80-90% after dehydration.After major part municipal sludge Chu Liao sewage treatment plants of China, just State is filled into unordered interim stacking or simply, do not only take up large amount of land resources, and heavy damage ecological environment, it is special It is not sewage intrusion underground water, causes part groundwater resources to be difficult to the permanent harm restored, simultaneously as moisture percentage in sewage sludge Height, the subsequent treatment expense of sewage treatment plant is on the one hand added, meanwhile, disposal, which is brought, after also giving directly affects.
The technique of sludge dewatering treatment includes sludge condensation, mechanical dehydration at present.Sludge generally use agriculture after dehydration With, landfill or burn method of disposal, following defect problem be present by this several method:
1st, for agricultural:Transport difficult, freight volume are big caused by moisture percentage in sewage sludge is too high, or because of dehydrated sludge cake difficulties in dispersion Field operation need to be supported by plant equipment, the technology more difficulty is in actual applications present;
2nd, filled:Because the higher soil mechanics property of dehydrated sludge cake moisture content is poor, a large amount of soil need to be mixed into, so as to cause The volumetric efficiency in soil substantially reduces;Simultaneously too high moisture content can also cause secondary because of the infiltration of leachate to soil Pollution;
3rd, dehydrated sludge cake directly burns, also because of the low calorific value that can not reach needed for maintenance process self-contained operation of its solid content, Auxiliary fuel need to be added, processing cost is substantially increased, it is difficult to is born.
The difficulty that the above-mentioned Treatment of Sludge of comprehensive analysis is run into actual applications with disposal technology system, is not difficult to find out dirt The moisture content of mud is crucial influence factor.Therefore, it is to solve what Treatment of Sludge was run into be permitted at present to reduce moisture percentage in sewage sludge The key of more problems.
As country is to the increasingly strict of environmental requirement, and the implementation of " ten, soil ", therefore carry out sewage sludge harmlessness, subtract Quantify the inexorable trend that will develop with recycling treatment as sludge disposal technology.
