| 摘 要： | 城镇污水处理厂污泥中的重金属是污泥资源化利用的潜在危害之一，因此如何有效去除污泥中的重金属是当前亟待解决的问题。在分析我国污泥重金属含量现状的基础上，对动电技术、生物沥滤法、化学浸提法和植物提取法等重金属去除方法进行了比较。通过比较可知，这四种方法的主要优势分别为去除效率高、适用范围广、操作简单、费用低廉。在分析这些技术与方法各自特点的基础上，指出了这些去除方法各自存在的问题及其研究进展。

| Abstract: | The heavy metal in the sewage sludge of municipal wastewater treatment plant is one of potential hazards to resource utilization of sludge. Therefore, how to effectively remove is a current problem to be solved quickly. Based on the present situation of heavy metals from the sewage sludge in China, the removal methods of heavy metals, such as electro-kinetic technology, bioleaching, chemical extraction and phyto extraction were compared. Through comparison, it is known that the main advantages of these four methods are high removal efficiency, wide range of applications, simple operation and low cost, respectively. The characteristics of each of these techniques and methods were fully analyzed, and the problems and research progress of these removal methods were pointed out. |
