【摘要】 采用室内静态杀菌实验方法 ,研究了复配杀菌剂 W112对太原热网循环水中富集分离的粘液异样菌群、硫酸盐还原菌群及铁细菌群的杀灭结果 ,结果表明 :(1) W112的杀菌浓度以 80 mg/ L为宜 ;(2 ) p H、温度、作用时间的不同均会影响W112杀灭粘液异养菌群、硫酸盐还原菌群及铁细菌群的效果 ;(3) W112杀菌作用的最佳 p H为 7～ 8,最佳温度为 35℃ ,作用 6 0 min即可达到较佳的杀菌效果更多还原

【Abstract】 Slimeforming heterotrophic bacteria,sulfate reducing bacteria and iron bacteria separated from the cycling hot water of pipeline in Taiyuan were sterilized by using fungicide W112 and statical sterilization method indoor.The results showed that:(1)the concentration of W112 at 80mg/L is optimal;(2)the effects of W112 on sterilizing for those bacteria will be affected by the change of pH,temperature,time for sterilizing when the concentration of W112 is at 80mg/L;(3)the optimal sterilization conditions of W112 when its concentration is at 80mg/L are pH 7～8,35 ℃ and 60 min respectively.更多还原
