摘要
城市污泥的再利用是普遍认可的一种污泥处理途径 ,针对上海 3种典型城市污泥 ,即曲阳生活污泥、金山石化污泥和桃浦化工污泥的特性进行了分析。结果表明 ,3种污泥中Zn和Cd的浓度都超过了相关标准 ,重金属的含量和污泥的类型有关 ,形态分布显著不同 ;曲阳生活污泥中不同气候条件下的大肠菌值≥ 12 0 0MPNs·g-1DM ,而且还有许多其它传染性病原体 ;关于优先控制有机污染物 ,金山石化污泥检出 6种 ,桃浦化工污泥检出 8种 ,而曲阳生活污泥中没有检出。本文还讨论了我国和欧美关于污泥农用的相关控制标准 。
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 MSS in 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 1 200 MPNs·g -1 DM,in addition to many other infectious pathogens.As for the priority of control organic pollutants, 6 kinds from Jinshan PSS and 8 kinds from Taopu CSS,were not found in Quyang DSS.The related control standards of USEPA EEC and SEPA.were also discussed.
