摘要
采用UV-Fenton高级化学氧化法处理酸性含氰废水,探讨了操作条件对氰化物处理效果的影响,结果表明:在pH值为3.5～4.5,停留时间为80 min,FeSO4与H2O2质量比为60∶1时,氰化物去除率达95%以上,出水中氰化物的质量浓度可达到20 mg/L以下,取得较好的处理效果,满足出水水质要求,该方法能够较好地去除酸性含氰废水中的氰化物。
UV-Fenton advanced chemical oxidation process was used to treat acidic cyanide containing wastewater,and the influence of operation condition on the treatment effect was discussed.The results showed that： when the pH value was 3.5-4.5,the retention time was 80 min,the mass ratio of FeSO4 to H2O2 was 60 ∶ 1,the removal rate of cyanide reached 95% or above,and the mass concentration of cyanide in the effluent water was below 20 mg/L.It could be seen that,using the said process to treat acidic cyanide containing wastewater could gain a good effect;the cyanide was removed effectively,and the effluent water quality met the discharge standard.
