摘要
离子交换系统制备纯水过程中会产生部分再生废液,目前采用沉淀中和等方法进行处理,但CODcr和总氮等环保排放指标仍有超标情况。对离子交换再生废液的水质水量进行了统计,分析了系统调整对水质的影响,对几种处理方法进行了探讨。
Ion exchange system produces some regenerated waste liquid during pure water generation.Though it is currently treated with the method of depositing neutralization, environmental discharge indicators such as CODcr and total nitrogen sometimes still exceed standard.The paper performs statistics of the water quality and volume of the ion exchange regenerated waste liquid,analyzes the effect of system adjustment on water quality and discusses on several treatment methods.
