氢氧化镉性质实验废水的处理探究

A Study on the Treatment of Experiment Wastewater with Cd^(2+)

按照源头控制污染理念,对氢氧化镉性质实验废水进行了回收处理,得到了可供实验循环使用的试剂CdSO4,其产率为99.32%,投入产出比为1∶37,达到了重金属实验废水"零排放"的环境要求目标.

Based on the idea that all kinds of pollution should be controlled at the headstream,in this study,experiment wastewater with Cd2＋ was treated and recycled,and the reagent CdSO4,which can be used in cycles during experiemnts was obtained with the recovery rate of 99.32%.The input-output ratio of the whole process was 1： 37.This study demonstrates that the approach of wastewater treatment at the headstream could meet the environmental requirments for zero discharge of experiment wastewater containing heavy metals.
