焦化废水物化系统不同药剂对出水氰化物的影响

Effect of Different Chemicals on Effluent Cyanides in Coking Wastewater Physicochemical System

氰化物作为焦化废水的特征性污染物之一,其碳氮键键能较高导致其难以降解处理。为使焦化废水出水氰化物这一指标能够稳定达标,先后在物化处理单元开展多种加药工艺及药剂的工业试验,力求保障出水氰化物指标能够稳定达标。主要阐述了煤焦化公司废水处理站的一系列工业试验并对其进行分析、概括与总结。

As one of the characteristic pollutants in coking wastewater,cyanide is difficult to degrade due to its high carbon nitrogen bond.In order to make the effluent cyanide in coking wastewater reaching the target stably,industrial tests of various dosing processes and agents have been successively carried out in the physicochemical treatment unit to ensure that the cyanide index in effluent can stably reach the target.The paper mainly discusses on a series of industrial tests of wastewater treatment station of coal coking company and analyses,summarizes and concludes the test results.
