摘　　要：为了解农村集中供水工程水质状况及变化趋势,加强农村饮用水安全管理工作,对2013—2018年的农村集中供水工程水质监测点进行枯水期和丰水期水样的采集与检测。结果表明,2013—2018年,共监测水样532份,合格373份,总合格率70.1%;微生物指标合格率最低,为75.8%;水质总合格率,微生物指标合格率均呈上升趋势(χ2值分别为11.41,13.34,P值均小于0.05)。不同规模供水工程水质总合格率、微生物指标合格率差异具有统计学意义(χ^(2)值分别为20.10、28.39,P值均小于0.001)。不同处理方式的水质总合格率、微生物指标合格率差异具有统计学意义(χ^(2)值分别为10.16、15.62,P值分别小于0.01、0.001)。不同消毒方式水质总合格率、微生物指标合格率差异具有统计学意义(χ^(2)值分别为37.90、41.43,P值均小于0.001)。北碚区农村集中供水工程水质总体较好,微生物污染是水质卫生质量不稳定的重要影响因素,应加强农饮水的消毒与监管。Provide a basis for understanding the water quality status and changing trends of rural centralized water supply projects and strengthening the management of rural drinking water safety.The water quality monitoring points of rural centralized water supply projects from 2013 to 2018 were collected and tested for water samples during dry and wet periods.The results showed that from 2013 to 2018,a total of 532 water samples were monitored and 373 were qualified,with a total qualification rate of 70.1%;the qualification rate of microbiological indicators was the lowest,at 75.8%;the total qualification rate of water quality and the qualification rate of microbiological indicators showed an upward trend(2 The values were 11.41,13.34,and the P values were all<0.05).The difference in the total qualified rate of water quality and the qualified rate of microbiological indicators of water supply projects of different scales was statistically significant(the two values were 20.10 and 28.39,respectively,and both P values were<0.001).The difference in the total qualified rate of water quality and the qualified rate of microbial indicators of different treatment methods was statistically significant(the 2 values were 10.16 and 15.62,respectively,and the P values were less than 0.01 and 0.001,respectively).The difference of the total qualified rate of water quality and the qualified rate of microbiological indicators of different disinfection methods was statistically significant(the two values were 37.90 and 41.43,respectively,and the P values were all<0.001).The water quality of the rural centralized water supply project in Beibei District is generally good.Microbial contamination is an important factor influencing the instability of water quality and hygiene.The disinfection and supervision of agricultural drinking water should be strengthened.
