摘要：
通过检测·OH间接生成率与COD去除率考察了Fenton氧化法深度处理炼化企业二级出水的效果及影响因素。结果表明,采用Fenton氧化法处理炼化企业二级出水,处理后的出水各项指标均达到《城市污水再生利用工业用水水质》(GB/T 19923—2005)的要求。最佳反应参数为:H2O2投加量为4 mmol/L,FeSO4·7H2O投加量为0.5mmol/L,废水pH=4,反应时间为2 h,反应温度为50℃。

Abstract:
The efficiency and influencing factors of the secondary effluent from petroleum refining and chemical industries have been investigated by means of detecting ·OH indirect producing rate and COD removing rate.The results show that by using Fenton oxidation process for treating the secondary effluent from petroleum refining and chemical industries,the indexes of the treated effluent meet the requirements of the Reuse of Urban Recycling Water:Water Quality Standard for Industrial Uses(GB/T 19923—2005).The optimal parameters are as follows:the H2O2 dosage is 4 mmol/L,FeSO4·7H2O dosage 0.5 mmol/L,pH=4,reaction time 2 h,and reaction temperature 50 ℃.
