摘要:重金属污染给生态环境及人类健康带来了极大的危害。重金属污染,根据其元素种类、含量以及存在形态的不同, 采
用不同的方法进行治理。本文综述了传统化学法、物理化学法及生物法等重金属污染水体治理技术的进展。最后指出了重金属污染
治理的发展方向,认为物理化学法及生物絮凝法在重金属水处理中有广泛的应用空间,组合工艺是提高重金属分离效率的一种可行
方法。

Abstract: Heavy metal pollution did an extreme harm to environment and human health. According to the different of
element type, content and the existence form s, different methods can be used in wastewater treatment of heavy metal. The
p rogress in the heavy metal pollution treatments in water was described, such as the traditional chem ical methods, physical
- chem ical methods and biological methods. Finally, a brief discussion on future developments was p roposed. The methods
of physical - chem ical and biological ulantswere pointed out, which had wild p rospect app lication of heavy metal pollu
tion water treatment. Combine p rocess was a feasible method in imp roving efficiency of heavy metals separating.
Key words: heavy metal; pollution; wastewater treatment
