碱性废水中Cr^(6+)的直接处理

Direct Treatment of Basic Waste Water Containing Cr^(6+)

研究了含Ｃｒ６＋碱性废水直接处理的可行性。结果表明,含Ｃｒ６＋碱性废水中加入七水硫酸亚铁直接处理,处理后的废水可达排放标准。Ｃｒ６＋去除率可达９９．８%。

The fesibility of direct treatment of basic waste water containing Cr6+has been studied. The result showed that the basic waste water containing Cr6+ could be treated directly by adding copperas. The treated waste water meets the discharge standard. The removal efficiency of Cr6+ could up to 99. 8 %.
