【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)。更多还原

【Abstract】 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(GB8978-1996).更多还原
