合肥及周边城市污水污泥重金属含量和农用潜在生态风险评价
Investigation of heavy metals contained in sewage sludge from municipal wastewater treatment plants from five cities and evaluation on their potential ecological risks in agricultural utilization
摘要
Abstract
Determination were conducted of five heavy metals content of Pb, Cr, Cu, Zn, and Cd in sewage sludge from municipal wastewater treatment plants, the biological reactions and the waster water in Hefei, Bengbu, Fuyang, and Huangshan city. The heavy metals removal rates and sludge removal loads of heavy metal were calcu lated. Compared with the background values of heavy metals in soil of Anhui province and average background val ues of that in Earth sediment, the toxicities of heavy metals were analyzed. Their pollution levels and potential eco logical risk were evaluated using potential ecological risk index. Some advices on agricultural application of the sewage sludge were given according to the national standards. The results indicate that the pollution levels and po tential ecological risk were different compared with different background values. The pollution level of factor of Cd was very serious compared with the background value in Anhui province leading to the serious potential ecological risk of the sewage sludge, while parts of them were serious compared with that in Earth sediment.关键词
