摘　　要：分析了电镀废水膜分离浓液的特点,提出了"高级氧化─重金属去除─生化处理"组合处理工艺。综述了几种常见的用于电镀废水膜分离浓液预处理的高级氧化技术,包括微电解、Fenton氧化、电催化氧化等,总结了加碱沉淀、离子交换、重金属捕集剂等重金属离子去除技术的优缺点,评价了BAF(曝气生物滤池)、A/O(厌氧/好氧)、MBR(膜生物反应器)等生化处理技术。展望了组合处理工艺的发展前景。The characteristics of reverse osmosis concentrate produced during the reclamation of electroplating wastewater were analyzed. A process combining advanced oxidation, heavy metal removal, and biochemical treatment was recommended. Some commonly-used advanced oxidation technologies such as micro-electrolysis, Fenton oxidation, and electrocatalytic oxidation were reviewed. The advantages and disadvantages of some heavy metal removal methods such as chemical precipitation, ion exchange, and using heavy metal capturing agents were summarized. Some biochemical treatment processes including BAF （biological aerated filter）, A/O （anaerobic/oxic）, and MBR （membrane bioreactor） were evaluated. The potential development of the combined process was proposed.
