摘　　要：有机硅废水酸度大,有机物成分复杂,浓度高,经过一二级处理难以达到排放标准。本实验使用经过物理生物方法处理过的废水,经过臭氧催化氧化和生物活性炭法(PACT)联用,来达到降低COD的目的。反应最佳条件为:臭氧催化氧化中pH值为8,投加接触面积为0.1 m 2/L的铜催化剂,反应时间为70 min,PACT法中投加粉末活性炭60 mg/L,废水停留时间24 h。COD从256.05 mg/L降至132.63 mg/L,最终去除率达到48.19%。本实验在传统方法的基础上进一步降低COD。Organosilicone wastewater with high acidity,complex organic composition and high concentration is difficult to reach the discharge standard after primary and secondary treatment.In this experiment,the waste water treated by physical and biological methods was combined with ozone catalytic oxidation and Powder Activated Carbon Treatment(PACT)to reduce COD.The optimum reaction conditions were as follows:the pH of ozone-catalyzed oxidation was 8,the copper catalyst with a contact area of 0.1 m 2/L was added,the reaction time was 70 min,the activated carbon powder 60mg/L was added by PACT method,and the residence time of wastewater was 24 h.COD decreased from 256.05 mg/L to 132.63 mg/L,and the final removal rate reached 48.19%.This experiment further reduced COD on the basis of the traditional method.
