摘要
本文介绍了二家氰化厂,分别采用酸化、碱氯、空气吹脱、贫液返回、自然暴晒、尾矿库废水返回再用等联合方法处理含氰废水的工艺流程,使最终排放的废水中氰化物和重金属离子的含量均达到国家允许的排放标准,并获得明显的经济效益.
This paper introduces a combined process to treat cyanide-bearing effluent in a couple of cyanide plants, i.e. acidification process, alkali-chlori-nation, blowing off with air, recycle of barren solution, heavy natural sunning reclaimation of waste water for reuse.By this method, the amounts of cyanide and heavy metals' ions in the waste water all come up to the domestic effluent standard and obtain economical benefits visibly.
