摘　　要：于2006年从全国范围内选取98个城市污泥样品,测定了其有机质及养分含量。结果表明,城市污泥中有机质、总氮、总磷及总钾的平均含量分别为280、29.6、22.2和5.83g/kg,其中总氮和总磷含量显著高于猪粪、牛粪和鸡粪的。与2001年的统计结果相比,城市污泥的总氮、总磷含量显著增加,总钾和有机质含量显著降低。To identify the concentrations of organic matter and nutrients in municipal sludge of China, samples of municipal sludge were collected from 98 sewage treatment plants in China in 2006. The results show that the average concentrations of organic matter, TN, TP and TK are 280 g/kg, 29.6 g/kg, 22.2 g/kg and 5.83 g/kg respectively, and the concentrations of TN and TP in the sludge are sig- nificantly higher than those in pig manure, dairy manure and chicken manure. Compared with the results of statistical analysis in 2001, the average concentrations of TP and TN in the sludge are significantly increased, while the average concentrations of TK and organic matter in the sludge are significantly decreased.
