目的了解晋中市农村饮用水的水质状况,为提高卫生质量提供科学依据。方法对晋中市所辖7个县75个乡监测点的水质卫生进行调查。结果2014年晋中市监测水样总体合格率为57.46%(354/616)。水样合格率枯水期(64.61%)高于丰水期(50.32%)(P<0.01);深井水(60.48%)高于浅井水(44.74%)(P<0.01);出厂水(73.28%)高于末梢水(53.54%)(P<0.01)。检测项目中微生物指标超标严重,主要不合格指标为菌落总数(90.91%)、总大肠菌群(70.13%)、大肠埃希菌(93.99%)、耐热大肠菌群(86.20%)、总硬度(94.81%)、硫酸盐(95.62%)、氟化物(95.29%)等。结论晋中市农村饮用水水质合格率偏低,微生物污染严重。
Objective To understand the water quality of rural drinking water in Jinzhong City and provide a scientific basis for improving the quality of hygiene. Methods The water quality and hygiene of 75 townships in 7 counties under the jurisdiction of Jinzhong City were investigated. Results The overall qualified rate of water samples in Jinzhong City in 2014 was 57.46% (354/616). The passing rate of water samples was higher in dry season (64.61%) than that in wet season (50.32%) (P <0.01), that in deep well (60.48%) was higher than that in shallow well (44.74% Higher than the peripheral water (53.54%) (P <0.01). The main indicators of unqualified microorganism in the test items were serious bacterial colonies (90.91%), total coliforms (70.13%), Escherichia coli (93.99%), heat-resistant coliforms (86.20% (94.81%), sulfate (95.62%), fluoride (95.29%) and so on. Conclusion Jinzhong rural drinking water quality qualified rate is low, serious microbial contamination.
