Characteristics of municipal sewage sludge and analysis on the prospects of its reuse

Abstract

Abstract: The reuse of municipal sewage sludge (MSS) is one of the generally accepted ways for sludge treatment.This paper analyzed the research results on the characteristics of three typical kinds of MSSin Shanghai:Quyang domestic sewage sludge (DSS),Jinshan petrified sewage sludge (PSS),and Taopu chemical sewage sludge (CSS).The concentrations of Zn and Cd in all the three kinds of sludge exceeded the standard values.Their contents were related to sewage types,and their morphological distribution was significantly different from each other.In the Quyang DSS,the contents of coliformbacteria under different climatic conditions were all above 1200 MPNs穏^-1DM,in addition to many other infectious pathogens.As for the priority of control organic pollutants, 6 kinds from Jinshan PSSand 8 kinds from Taopu CSS,were not found in Quyang DSS.The related control standards of USEPA EEC and SEPA.were also discussed.

Key words: Forest-grassland boundary, Soil moisture content, Geostatistics, Spatial distribution
