摘要
铬及其化合物被广泛应用于电镀工业中,产生大量含铬废水,并成为一种主要的环境污染物质。通过试验对几种含铬废水的处理方法作了比较,阐明了各种方法的优缺点及实际处理工艺中的应用价值;同时将铬作为有用资源,通过不同的工艺得到铬酸钠、重铬酸钾、铬黄等,加以回收利用,这不仅体现环境效益,同时也取得了一定的经济效益。
Chromium and its compounds are widely used in electroplating industry.Generate a large number of chromium-containing wastewater.And become a major environmental pollutants.In this paper,tests of several chromium-containing wastewater treatment methods are compared.Clarify the advantages and disadvantages of each method and the actual value of Process.At the same time as a useful resource for chromium.Through different processes to be sodium chromate,potassium dichromate,chrome yellow,etc.For recycling.This not only reflects the environmental benefits of.Also made some economic benefits.
