摘　　要：随着工业化的推进,重金属污染问题日益严重,重金属离子易与有机络合剂形成重金属络合物,常规的水处理方法难以对其进行有效去除。讨论了络合态重金属的主要处理技术,包括化学沉淀法、氧化还原法、光催化氧化方法、光电催化氧化方法以及吸附法等,分析了各种方法的优缺点,并展望了今后技术发展的方向。With the propulsion of industrialization, heavy metal pollution problems are getting more and more serious. Heavy metal ions are easy to combine with organic complex ,forming heavy metal complex, which is difficult to be removed by conventional water treatment methods. The main treatment technologies for treating complexed heavy metal,including chemical precipitation,oxidation and reduction,photocatalytic oxidation,photoelectric catalytic oxidation, adsorption, etc., are discussed. Their advantages and disadvantages are analyzed, and the future technical development direction is predicted.
