Sewage Sludge Treatment & Engineering Using Of The Wastwater Treatment Plants

There are lots of sewage sludge in sewage disposal course ,if we do not disposal and treatment those sewage sludge ,it will pollute our environment .Before we use all-pervading method such as gravitaty inspissation,nature dry ,machine dehydration.Along with develop of economic and raise people's standard of living ,so you say those method not able to content our needs .so it must be have a new method deal with sewage sludge In Sewage disposal factory.In this paper,summarizing sewage sludge's character and effecting factor; analyzing practicability of sluge's accounting formula in coutry inside and outside; also expatiating on sludge's disposal method and machine dehydration,style of de-watering machine basis on WTP's scale,water qualitya,require of disposal technics and sludge's character. At the same time their merit and shortcomings are also discussed. At last,dewelling on machine dehydration combine with Chengdu No.2 Wastewater Treatment Plant.
