摘要
采用电化学法消毒处理医院污水,通过选用不同阳极材料构建的电化学体系,探讨电化学法的消毒机理。试验表明,以涂有贵金属(钌、铂和铱)氧化物的钛板作阳极,不锈钢板作阴极,在电流密度为8 mA/cm2、水力停留时间为15 m in、空气流量为40 L/h、极水比为1.0的试验条件下,消毒后污水中总大肠菌群数<500 cfu/L,达到国家一级排放标准(GB8978-1996)。
Electrochemical disinfection method was used to treat hospital sewage. The mechanism of electrochemical disinfection was researched by using different anode materials. The results showed：when the titanium coated with noble metal （Ru, Pt, Ir） oxide was used as anode, stainless steel was used as cathode, current density was 8 mA/cm^2 ,hydraulic retention time was 15 min,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 colibacillus was below 500 cfu/L after electrochemical disinfection.it reached the first order of effluent discharge standard （ GR8978-1996）.
