Progress in Domestic Urban Sewage Treatment Sludge Dewatering Technology
With the increasingly complex composition and increasing amount of sludge,the proper treatment and disposal of sludge has become an increasingly urgent environmental problem in many cities and towns in China.In response to the high moisture content of sludge,difficulties in loading,unloading,transportation,and subsequent disposal,this paper summarizes the research progress of common and recent technologies in sludge dewatering and reduction in China,and puts forward relevant suggestions.Economically efficient,low-carbon and energy-saving sludge dewatering technology and equipment will be the future focus of research in the field of sludge treatment.
