摘要
介绍了重金属的含义及特点,从化学沉淀法、离子交换法、吸附法、膜分离法、光催化技术五方面,阐述了重金属废水常用的处理方法,并分析了各种方法的优缺点及适用范围,对重金属废水处理技术的深入研发有一定的意义。
The paper introduces the definitions and features of heavy metal. Starting from aspects of chemical sedimentation tank method,ion-exchange method,adsorption method,membrane isolation method and photocatalysis technique,it describes common heavy metal wastewater processing methods,and analyzes their merits and defects and application scope,which has certain meaning for further studying heavy metal wastewater processing technique.
