【摘要】 采用Fenton氧化法对含油废水进行了深度处理,探讨了H₂O₂浓度、氧化剂与催化剂比例及催化剂改进等因素对废水中COD、BOD₅去除率的影响,结果表明:（1）随着H₂O₂浓度增加,含油废水中COD和BOD₅的去除率均呈现出先增加后逐渐下降或稳定的趋势,在浓度为40mmol/L时达到最大值;（2）随着氧化剂︰催化剂比例的增加,COD的去除率随之逐渐下降;（3）在H₂O₂浓度为60 mmol/L、H₂O₂︰Fe³⁺为10︰1、pH值为3的正交实验条件下,其平均去除率最高,达到了73.48%,该结论可为含油废水深度处理提供实验依据。更多还原

【Abstract】 The Fenton oxidation method was used for advanced treat the oily wastewater. The effects of H₂ O₂ concentration, the ratio of oxidant and catalyst and improved catalyst on the removal efficiencies of COD and BOD₅ in wastewater were investigated. The results showed that:（1） the removal efficiencies of COD and BOD₅ in the wastewater were tendencies of first increase and then gradually decrease or stabilize with the increase of H₂ O₂ concentration and reached a maxi-mum at a concentration of 40 mmol/L,（2） with the increase of the ratio of oxidant and catalyst, the removal efficiency of COD was decreased gradually,（3） under the orthogonal experimental conditions of H₂ O₂ concentration of 60 mmol/L and H₂ O₂:Fe³⁺ of 10:1 and pH value of 3, the average removal efficiency was the highest and reached to 73.48 percent. This conclusion can provide for experimental basis in the advanced treatment of oily wastewater.更多还原
