摘　　要：采用Fenton试剂预处理高氯化工废水,考察了主要影响因素,确定了最佳工艺参数.结果表明,在pH值为4,H2O2投加量325 mmol,FeSO4投加量20.8 mmol,反应时间90 min的条件下处理250 mL废水,COD去除率达到64%以上,B/C值由0.016提高到0.35,水质得到明显改善,有利于后续生化处理.The high - chloride chemical wastewater was pretreated using Fenton reagent. The dominant influencing factors were discussed and the optimal technological parameters were determined. The results showed that the COD removal rate was more than 64% and the B/C increased from 0. 016 to 0.35 under the conditions of pH value of 4. The dosage of H2O2 was 325 mrnol. The dosage of FeSO4 was 20.8 mmol and the reaction time was 90 min for 250 mL wastewater. The quality of the water was improved obviously and favorable to the latter biochemical processing.
