减少废水中氰含量的有效途径

摘要

焦化废水成分复杂，处理难度大。焦化废水的主要来源是蒸氨废水，采用水解的方法去除剩余氨水中的氰，降低蒸氨废水中的氰含量，使污水处理站处理后的废水氰含量达标。%As the composition of coke plant wastewater is very complicated, it is very difficult for treatment. The main source of coke plant wastewater is ammonia stripping wastewater, and this paper uses hydrolysis method for removing the cyanide in coal water to reduce the cyanide content in ammo-nia stripping wastewater, so that the cyanide content in wastewater after treatment in wastewater treat-ment station could reach the required standard.
