Research on Sewage Sludge Integrated Treatment Model:a Case Study of Dongtai Xiajiahezi Sludge Treatment Plant in Dalian

Problem of sewage sludge treatment has been the bottleneck on the development in water treatment industry.Face to the significant increase of sewage sludge volume,the original approaches can not solve the issue of sewage sludge treatment and utilization in effective way.Based on systemic analysis of the recent development of sewage sludge treatment,and reference to foreign advanced experiences and domestic reality,this paper focus on proposing sewage sludge integrated treatment model(SSITM) to resolve the sludge problem,meanwhile achieving the resource recycle.Finally,we analyze the application of SSITM in case study in Dalian.
