摘要
采用二氧化氯对含氰农药废水进行处理,在ClO2/CN-为3.5～4.5(质量比),pH值为11.5,搅拌反应2 h的条件下,对于氰化物浓度(以CN-计)60～80 ng·L-1的废水氰化物的去除率达97 %以上.实例表明,利用二氧化氯处理含氰农药废水,具有去除效率高,运行稳定,操作安全方便,自动化程度高等优点.
ClO2 was applied to treat the pesticide wastewater contained cyanogens. When the mass ratio of ClO2 and CN was 3.5-4.5, pH was 11.5 ,the cyanide removal rate of wastewater with cyanide mass concentration 60-80 ng/L（counted by CN^-） was more than 97% after 2h stir reaction. The treatment results showed that this method had higher removal rate, steady running, safety and easy operation, high automation degree, and so on.
