Analysis on the Monitored Results of Microbial Indicators in Rural Drinking Water of a City from 2011 to 2015

摘要

摘要:
目的分析某市2011—2015年农村饮用水微生物指标监测结果、查找农村饮用水微生物超标影响因素。
方法定期开展农村饮用水中的菌落总数、总大肠菌群、耐热大肠菌群检测，按照国家标准进行检测和判定。
结果 2011—2015年共检测饮用水样品1 550份，农村饮用水微生物合格率逐年提高，且微生物指标合格率与水源类型、处理方式和水质消毒关系密切。
结论某市农村饮用水微生物指标合格率不高，建议加大投入，改善制水工艺，落实消毒措施，保障农村饮用水安全。

Abstract:
Objectives To analyze the monitored result of microbial indicators in rural drinking water of a city from 2011 to 2015, to find out the influence factors for unqualified microbial indicators of drinking water in rural areas.
Methods The determination of the total number of colonies, total coliforms, heat-resistant coliform bacteria in rural drinking water was carried out regularly and adjusted according to the national standards.
Results A total of 1 550 rural drinking water samples were collected from 2011 to 2015, the qualified rate of three microbial indicators were increased year by year, and the qualified rate for microbial indicators and forms of water source were closely related to treatment and disinfection.
Conclusions The gualified rates of microbial indicators for rural drinking water in the city was not high; in order to protect the safety of rural drinking water, it was proposed to increase investment, improve the processing of water supply and implement disinfection measures.
