含氰电镀废水氧化处理的研究

Study on Oxidation and Disposal of Plating Waste Water Contenting Cyanogen

采用次氯酸钠氧化处理含CN电镀废水,并对其主要工艺条件、处理效果等进行了试验研究。以次氯酸钠氧化处理CN—含量为1.0168 mgL-1电镀废水,可除去废水的96.6% CN—,经次氯酸钠氧化处理后,废水CN—的含量平均低于国家排放标准的24.9分之一。

Oxidize plating waste water by using hypochlorous acid sodium as well study its techical conditions and disposal effect. The result indicated that the 96.6% of CN-can be eliminated in plating waste water that its content was 1.0168 mgL-1 by hypochlorus acid sodium and the average content of CN- in the waste water is lower than the 1/24.9 of the letting criteria of country after it was disposed.
