萍乡市部分农村饮水安全工程水质卫生监测结果分析

Analysis on Results of Monitoring Water Quality in Rural Drinking Water Safety Project in Pingxiang

摘要

摘要:
目的了解萍乡市农村饮用水安全集中供水工程水质卫生现状,为提高农村饮用水卫生管理水平,制定干预措施提供技术依据。
方法分别于2012年枯水期和丰水期采集各监测点出厂水和末梢水各1份,按照标准检测方法进行水质卫生检测。
结果萍乡市集中式供水水源以地下水为主,地面水源覆盖人口数高于地面水源。检测指标中超标率较高的分别为总大肠菌群(26.79%)、耐热大肠菌群(20.15%)及菌落总数(24.49%)。
结论萍乡市部分农村集中式供水水质卫生存在安全隐患,水体受微生物污染严重,消毒工作未有效开展是造成其主要原因。

Abstract:
Objectives To understand the hygienic status of centralized water supply in the rural drinking water safety project in Pingxiang city,to improve the management level of rural drinking water,and to provide technical basis for developing intervention measures.
Methods The quality of finished water and tap water samples collected in dry season and wet season in 2012 from all monitoring points were inspected according to the standard methods.
Results The source of centralized water supply was based on underground water,underground water covered more population than ground water covered. The indexes with higher unqualified rate were total coliforms (26.79%),thermotolerant coliform bacteria (20.15%) and the total count of colonies (24.49%).
Conclusions There were hidden safety problems in centralized drinking water supply in rural areas of Pingxiang city. Ineffective disinfection is the main cause of microbial contamination.
