摘　　要：络合废水中重金属与有机酸之间交互影响,导致常规方式分离重金属难度高、效果差,因此其处理成为近年来重金属污染控制热点与难点。文章在调研大量重金属-有机酸络合废水处理前沿技术的基础上,对沉淀、吸附、铁置换/还原以及高级氧化等重金属-有机酸络合废水处理技术进行了回顾与总结,并分析了其优缺点及优化方向。指出可实现络合废水中COD高效去除及重金属同步回收,不产生二次污染的高效低耗新技术是今后此类废水处理的主要难点和发展重点。The interaction of heavy metals and organic acids in the complexing wastewater leads to high difficulty in heavy metals separation by traditional technologies. Therefore, effective treatment of heavy metal-organic acid complex wastewater has become a hot and difficult point in recent years. Based on the investigation of the leading technologies for heavy metalorganic acid complexation wastewater treatment, chemical precipitation, adsorption, Fe(Ⅲ) displacement/reduction and advanced oxidation processes are reviewed and summarized. The merits, demerits and improvement strategies of these methods are compared and analyzed. It should be pointed that developing technologies with high efficiency and lower consumption,realizing the efficient removal of COD and the recovery of heavy metals synchronously, and producing little secondary pollutants, will be the main difficulty and research direction for the complexed wastewater treatment.
