摘    要：采用针-板电极脉冲放电处理含氰废水,分别研究了溶液初始pH值、放电时间、气流量、气体种类及放电方式等试验条件对氰化物去除率的影响。试验结果表明:氰化物在pH值为9～10时去除率较高,且随着反应时间的延长、气流量的增加而增加,通入空气时氰化物的去除效果好于通入氮气时的去除效果。

Abstract: The paper sets forth a new approach to treat cyanide wastewater using impulsive discharge with needle-board electrode.Some factors that influence the removal rate of cyanide are discussed,including pH value,reaction time,flux of gas,gas type and discharging conditions.The results show that the removal rate is the highest,when pH value is 9.The removal rate increases gradually with the increasing of gas flux and reaction time.The removal effect of CN is better with air flow than with nitrogen gas flow.
