摘　　要：采用Fenton氧化技术对棉浆黑液废水进行深度处理,通过单因素与正交试验,研究了pH、FeSO4投加量、H2O2投加量和反应时间等因素对COD去除率的影响,分析了各影响因子的作用机理。结果表明,处理废水的最佳条件为:废水初始pH=7、FeSO4投加浓度80mmol/L、H2O2投加浓度0.15mol/L、反应时间40min,在此条件下黑液COD去除率98%,处理后黑液的COD为45mg/L,达到国家化纤废水一级排放标准(COD<100mg/L)。Fenton oxidation has been investigated in order to effectively treat cotton pulp black liquor in chemical fiber factories. The effects of pH, ferrous sulfate dosage, hydrogen peroxide dosage and reacting time on COD removal rate are studied. The mechanisms of influential factors on treating cotton pulp black liquor by Fenton reagent are preliminarily analyzed. The optimal conditions determined by single-factor and orthogonal experiments are as follows： initial pH=7.0, FeSO4 dosage 80 mmol/L, H2O2 dosage 0.15 mol/L, and reacting time 40 min. Under the optimal conditions, the ultimate COD removal rate is 98%. The COD of the treated black liquor is 45 mg/L, which reaches the First Discharge Standard of National Chemical Fiber Wastewater （COD〈 100 mg/L）.
