摘　　要：以Fenton试剂处理兰州某化工厂有机废水。结果表明,Fenton反应的最佳操作条件为:H2O2投加量为0.15 mol/L,FeSO4投加量为4 mmol/L,初始pH为3,反应时间90 min。在最佳工艺条件下,有机废水色度去除率达98%以上,出水呈无色,COD Cr去除率达80%以上,同时出水B/C值大幅提高,达到0.49,预处理效果良好,有利于进一步生化处理。The organic chemical wastewater from a chemical plant in Lanzhou was investigated by Fenton reagent. The result showed that the optimum experimental conditions were as follows ： H2 02 concentration 0.15 tool/L, FeSO4 concentration 4 mmol/L, pH = 3 and 90 min. Under the optimum reaction conditions, the removal rate of chroma was more than 98% and the effluent was colorless, and the removal rate of CODcr reached more than 80%. Furthermore, the B/C of effluent was enhanced greatly to 0.49. The result of the pretreatment was very satisfied, and the method was in favor of next biochemical treatment.
