摘　　要：有毒重金属对环境的严重威胁正逐渐成为全球性问题,着重综述了近年来国内外重金属污染处理技术的研究与进展。除了改进传统的化学、物理方法外,各种廉价高吸附性能的吸附剂、新型可选择性重金属捕集剂都是研究的焦点。特别是随着生物技术的发展,利用功能菌和植物处理含重金属污染已取得相当成效,并在工业上进行了实际应用。研究和发展新型天然吸附剂、重金属捕集剂和生物技术,加强多种技术的综合应用,是治理重金属污染的有效途径。The serious threat of poisonous heavy metal pollution to the environment becomes a global problem. The researches and developments on heavy metal pollution treatment at home and abroad are summarized in this paper. Besides the improved traditional chemical and physical methods, the low-priced, high adsorption properties of adsorbent and new style heavy metal chelating agents are the focus of research. With the development of biological technology, functional bacteria and plants are more efficient in heavy metal treatment and are pratically used in industries. Combined application of various technologies is the potent way to heavy metal treatment based on advances of new-style natural adsorbents, heavy metal chelating agents and biological technology.
