摘要
多晶硅企业生产产生的尾气经水洗后成为含有盐酸的废水利用这些废水可制备水处理剂——聚合氯化铝。此工艺得到的产品符合国家水处理剂产品指标要求,是一种环保、经济的生产方法。
This paper introduces the polysilicon production generated the exhaust, after washing with water, resulting the wastewater containing hydrochloric acid. Such waste water can be used to product the waste water treatment reagent. This process and production in a small trial has been successfully. Products meet the national water treatment agent product index.It is a kind of environmental protection and economic production process.
