摘要
污水生物处理过程中很多较强毒害作用的有机污染物转移到活性污泥中,进而影响了污泥的土地利用。本文依据对生态环境及人类健康的影响,以7种受关注度比较高的典型新兴有机污染物为对象,综述了其在污泥中的赋存状况,同时对这些污染物可能对污泥土地利用产生的影响进行了分析。最后,对7种新兴有机污染物在污泥中的赋存状况进行了总结,并对相关研究方向进行了展望,指出应继续分析和监测污泥中有机污染物,尤其是新兴有机污染物对生态环境的影响和危害,并深入研究污泥中这些物质的有效降解途径与方法,使污泥能够安全地进行土地利用。
In the biological treatment of wastewater,lots of toxic organic pollutants were transferred to the activated sludge and then gave negative effects on the land application of sludge.In this paper,seven kinds of remarkable typical emerging organic contaminants were chosen based on their effects on ecology and human health and the pollution situation of these contaminants in sludge was reviewed,the possible effects on land application of sludge were analyzed.Then,the related research orient was forecasted,indicating that it is necessary to analyze and determine the effects and toxicity of organic contaminants on the ecology,especially the emerging organic contaminants in sludge,and further explore the effective method for the biodegradation of these organic compounds in order to make the land application of sludge safer.
