摘要 采用循环流反应器,以DSA(Ti/IrO2-RuO2)电极为阳极,考察了3种不同材质阴极(CuZn合金、Ti、Zn)对电化学消毒效果及无机消毒副产物生成的影响,同时探究了电流密度、初始Cl-浓度与初始pH对该过程的影响。结果表明,在相同的实验条件下,阴极材质的改变对电化学消毒效果无明显影响,但采用CuZn合金阴极较其余2种阴极生成的氯酸盐更少。电化学析氯消毒对大肠杆菌的灭活效果随着电流密度与初始Cl-浓度的升高而升高,随pH升高而降低。

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.
Key words:  electrochemical disinfection    cathode material    active chlorine    E-coli    disinfection by-products
