两种处理电镀铬废水方法的比较

Comparision of Two Methods for Chromium Electroplating Waste Water Treatment

硫酸亚铁法和亚硫酸氢钠法是目前处理含六价铬废水常用的方法,但它们的处理工艺存在着明显的不同,通过试验研究、对比,指明了在不同的场合采用适宜的方法可以获得更佳的综合效果,从而为生产实践中电镀铬废水的处理提供参考。

The ＂ Ferrous Sulfate Method＂ and the ＂Sodium Bisulfite Method＂ are two common methods for chromium plating waste water treatment. There are obvious dissimilarities in the two technologies. It was indicated that some better effects for the wastewater treatment could be gained by adopting appropriate methods in some special situations, and it could be offerd as a reference for the chromium plating waste water treatment in practice production.
