摘　　要：应用新型电极材料进行电解电位水的无药化制备,并对出水的应用效果进行了试验研究。结果表明,当酸性电位水用于饮用水消毒时,在原水细菌浓度为6.7×104CFU/mL的情况下,对细菌总数的瞬间杀灭率≥99.94%;当用于表面消毒时,在阳性对照组菌落数为3.4×104CFU/mL的情况下,作用1 m in时灭菌率为96.9%,3 m in时为98.5%,其消毒效果优于同浓度的C lO2。碱性出水随着流量的降低,其pH值和还原电位逐渐升高,出水中CODMn值无明显变化,对UV254的去除率与流量呈明显的线性关系,表明碱性电解工艺可去除水中以UV254为代表的毒性物质,提高了饮用水的水质安全性。Taking the advantage of new electrode materials to generate electrolyzed potential water without chemicals, the application effectiveness of effluent was studied. The result shows that acidic potential water, acting as the drinking water disinfectant, can attain a killing rate of 99.94% or more for the total count of bacteria when the original water bacterium density is 6.7 × 10^4 CFU/mL. When it is used for surface disinfection, with 1 and 3 minutes contact times, the killing rates are 96.9% and 98.5% for E. coli when the bacterium density of positive control group is 3.4 ×10^4 CFU/mL. RP and pH of alkaline potential water increase with the flux reducing; CODM, does not have any visible changes; pump capacity and removal rate of UV254 have an apparent linear relation, which means that the electrolysis process can remove some toxic substances in water.
