摘要
连续3年监测桂林市区10个供水管网点的微生物污染情况,并分析其原因。按照GB/T 5750-2006《生活饮用水标准检验方法》相关要求进行采样、检验,对检测结果进行分析和讨论。结果显示,采样点的菌落总数呈现差异,表明不同管网点微生物污染程度不同。自来水中微生物污染的原因较复杂,涉及管网长度、设计、实际用水量和管网材料等,本文提出了改善建议。
To analyze the causes of microorganism contamination of10water supply outlets in Guilin,this paper monitor the condition for3years.To sample and test according to the requirements of the GB/T5750-2006,analyze and discuss the result.The result showed that the differences of the total number ofcolonies of the sampling points indicated that the microbial contamination of different outlets was different.Thereason of microbial contamination in tap water is more complicated,it related to the length of the pipe network,design,actual water consumption,pipe materials,so this paper put forward to the improvement suggestions
