摘要
采用Fenton试剂氧化法对高浓度霜脲氰废水进行处理,考察其对CODcr及NH3-N的降解效果。实验结果表明,废水初始pH、七水硫酸亚铁、双氧水投加量和反应时间均对废水的CODcr及NH3-N去除率产生影响。霜脲氰废水处理条件为:pH=4,七水硫酸亚铁投加量5 g/L,双氧水投加量100 ml/L,反应时间100 min。CODcr去除率最高达45.14%,NH3-N去除率最高为39.98%。
Fenton reagent was used for treatment of wastewater containing high concentration of cymoxanil. The removal rates of CODcr and NH3-N were 45.14% and 39.98%,respectively,under optimal conditions of pH value of4,the dosage of FeSO4·7H2O of 5 g / L,the dosage of hydrogen peroxide of 100 ml / L,and the reaction time of 100min.
