联合法处理电镀镉废水的研究

The Combined Method to Processing the Cadmium Wastewater

利用电解法与光触媒法的联合处理方法(以下略称联合法)对工厂中的镉废水进行处理。与电解法和光触媒法相比,联合法可以使处理后的废水中总有机碳含量含量更低,并且所需反应时间更短,进而降低生产成本。实验结果表明,在酸化时间3.5h的条件下,废水处理后各种产物含量低于我国废水排放标准,可以进行直接排放.

This paper is based on the research of wastewater draining from factories by using the new improved acid method.Comparing with the trad electrolysis and photocatalytic methods,the results showed the TOC of wastewater reduced greatly in the litter reactive times.Furthermore,the production cost can be reduced.At the same time,it also can be shown that the wastewater resultants are mainly fatty acid,and its consistency can be lowered below wastewater discharge standard,when the acidification time is about 3.5 hours.
