摘　　要：应用电化学方法消毒处理医院污水,比较不同阳极材料消毒效果,并探讨消毒机理.试验表明,以涂有贵金属(钌、铂、铱)氧化物的钛板作阳极,不锈钢板作阴极,在电流密度6 mA/cm2、水力停留时间15 m in、空气流量为40 L/h、极水比为1.0的试验条件下,消毒后污水的总大肠菌群数<500CFU/L,达到国家一级排放标准(GB8978—1996).Electrochemical disinfection method was used to treat wastewater from hospitals. The mechanism of electrochemical disinfection was researched by using the different anode materials. The results showed that when the titanium coated with noble metal（Ru,Pt,Ir） oxide was used as an anode and stainless steel as a cathode, the current density was 6 mA/cm^2, hydraulic retention time was 15 rain, air flow rate was 40 L/h, the rate of anode effective area to the inner water volume was 1.0, the amount of total colibaciUus was below 500 CFU/L after electrochemical disinfection, All these meet the first order of Effluent Discharge Standard （GB8978-98）.
