摘要
简述了全国范围内污泥中重金属赋存水平以及污泥施用到农田后重金属产生的危害,重点阐述了采用物理、化学、微生物方法去除污泥中重金属,并对这几种方法的去除效率、处理成本以及环境安全性进行了比较,最后展望了今后进一步研究的发展方向和工作重点。
This paper dissertate the existing level of heavy metal in sludge and the harm of the heavy metal of sludge after land application, in which the methods of removing heavy metal from sludge by physics, chemistry and microbiology are elaborated emphatically, while the removal efficiency, the cost as well as the environmental security of the methods are also compared. Finally this article forecast the developing direction henceforth and the emphases of research in the future.
