电子工业重金属废水处理工艺设计实例

Design of Heavy Metal Wastewater Treatment Process in Electronic Industry

废水中的重金属不能被生物降解为无害物,而只能通过物理、化学方法转移它们的存在位置和转变它们的物化形态。本文重点介绍了酸碱废水、含铬(Cr)废水、含镍(Ni)废水的化学法处理工艺,可以为相关工程工艺设计提供借鉴。

Heavy metals in wastewater can not be biodegraded into harmless substances,but can only be transferred by physical and chemical methods and their physical and chemical forms can be changed.In this paper,the chemical treatment processes of acid-alkali wastewater,chromium(Cr)wastewater and nickel(Ni)wastewater are mainly introduced,which can be used for reference in relevant engineering process design.
