摘　　要：分别富集循环水中异养菌、铁细菌、硫酸盐还原菌,考察了过氧乙酸对这三种细菌的杀菌效果及维持作用时间,同时也考察了过氧乙酸与现行水稳剂配方的协同配伍性及对金属材质腐蚀的影响,并进行了工业现场杀菌试验,结果显示效果良好。说明了过氧乙酸是一种新型绿色环保型杀菌剂,具有很大的应用前景。Peroxy acetic acid is a new green germicide with application prospect. Heterotrophic bacteria, iron bacteria and sulfate reducing bacteria in circulating cooling water were enriched separately. The (disinfecting) effect and the effective time of peroxy acetic acid for these bacteria were studied .At the same time, the compatibility with the present water treatment formula and the corrosiveness to some metals were investigated. Commercial scale disinfection test was made with good result.
