摘要
重金属废水不仅对生态环境带来毁灭性的破坏,还间接地危害人类健康。以重金属离子在无害化处理前后的形态变化为依据,重金属废水的无害化处理技术可分为化学转化技术、介质提取技术和物理化学浓缩技术,作者主要综述了各种无害化处理技术的最新研究进展,同时简述了重金属废水资源化技术,并提出了一条新的重金属废水无害化处理与资源化利用的技术路线。
Heavy metal wastewater not only brings about destructive effects on environment, but also do harm to human health indirectly. According to the modal changes of heavy metal ions before and after the harmless treatment process, the harmless treatment technologies of heavy metal wastewater can be classified into three kinds：chemical conversion technology, media-based extraction technology and physiochemical concentration technology. The latest research advances in harmless treatment technologies are summarized. Some beneficial utilization technologies of heavy metal wastewater are stated briefly and a new technical route for harmless treatment and beneficial utilization of heavy metal wastewater are put forward.
