摘要
以硫酸盐还原菌,铁细菌以及异养菌数为指标,考察了二氧化氯投加量,杀菌时间,温度及pH值几种影响因素以及余氯量随时间的变化。结果表明,在投加浓度为3 mg/L,处理时间为90 min时,杀菌率达98.33%,2 h内余氯大于0.6 mg/L。
According to the count change of sulfate-reducing bacteria,iron bacteria and heterotrophic bacteria.Research the sterilization effects of chlorine dioxide dosage,disinfection time,temperature and pH.The results show that, when the chlorine dioxide dosaging concentration is 3 mg/L and the operation time was 90 min, the sterilization efficiency reached at 98.33 % and the concentration of residual chlorine was above 0.6 mg/L in two hours.
