摘要
概述了重金属废水的主要来源及重大危害,介绍了重金属废水的常规处理工艺和膜处理法。重点介绍了前者中的吸附法、沉淀法、电化学法以及后者中的反渗透膜法、超滤膜法、纳滤膜法等工艺原理与研究状况,并对重金属废水处理方法的研究趋势迚行了合理展望。
Main sources and major hazards of heavy metal wastewater were summarized,and the conventional treatment processes and membrane treatment methods of heavy metal wastewater were introduced.The principles of adsorption method,precipitation method,electrochemical method,reverse osmosis membrane method,ultrafiltration membrane method and nanofiltration membrane method were discussed.The research trend of heavy metal wastewater treatment method was forecasted reasonably.
