Abstract: The impacts of three different cathode materials (CuZn alloy,Ti and Zn) on the electrochemical disinfection performance and the generation of inorganic disinfection by-products are investigated in a recirculating flow reactor with DSA (Ti/IrO2-RuO2) as the anode.Meanwhile,the influences of current density,initial Cl- concentration and initial pH value on the circulating flow reaction are explored.It is found that the impact of different cathode materials on disinfection performance is insignificant under the same experimental conditions.However,the production of chlorate by applying CuZn alloy as the cathode is less than that by using the other two materials as cathode.In addition,the inactivation effect of E-coli by electrochemical chlorine-evolution disinfection increases with the increases of current density and initial Cl- concentration,and decreases with the increase of pH.
