| 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). |
