摘　　要：以白酒酿造黄水和造纸废水为处理对象,初步研究了Fenton试剂处理有机废水时双氧水利用率的影响。结果表明:Fenton试剂中氧化剂H2O2和催化剂Fe2+的浓度,以及反应体系pH值、反应时间等因素对H2O2的利用有较大的影响。从H2O2利用率、运行成本、避免二次污染等角度综合考虑,反应条件控制为pH 3～4、搅拌反应时间90min、H2O2加入量4 ml.L-1、FeSO4.7H2O投加量0.2 g.L-1较为合理。The factors which influence the utilization ratio of H2O2 in treating organic wastewater such as DISTILLED YELLOW WATER, paper making wastewater by Fenton reagent were preliminarily investigated. Experimental results show that the operating conditions such as the dosage of H2O2, the concentration of Fe2＋, pH, reaction time are major affecting factors, and that the preferable conditions are as following： initial pH value of 3- 4,stirring for 90 min, the addition amount of H2O2 of 4 ml.L-1, the dosage of FeSO4.7H2O of 0.2g.L^-1.
