曲阜市农村生活饮用水卫生监测结果分析

Hygienic Monitoring and Analysis on Rural Drinking Water of QUFU City.

目的为全面了解我市农村生活饮用水卫生状况并为今后农村开展改水提供科学依据。方法通过现场调查和采样监测,收集自2003年连续四年的监测资料,依据《生活饮用水卫生标准》对水质质量做出科学客观的评价。结果大肠菌群和细菌总数超标严重,浅井水细菌总数和总大肠菌群不合格率分别为39.7%和35.3%;各年度水质变化相对稳定(P>0.05);深井水和浅井水水质合格率差异有统计学意义(P<0.05)以及丰水期和枯水期水质亦有差异(P<0.05)。结论我市农村分散式供水主要受生活性污染,提示需加强农村水源保护,做好饮水常规处理和监测,以提高饮水卫生质量。深井水水质合格率较高,所以农村改水应尽量选择深层地下水为水源水。

Objective To find out the sanitary quality of rural drinking water and provide scientific proof for Improving drinking water in countryside. Methods Field investigation, sampling and monitoring were carried out. The data were collected in recent four years since 2003. The water quality was evaluated by the health criteria of drinking water. Results The rate of total coliform and total bacterial count exceeding the sanitary standard was 39.7% and 35.3% respectively;The difference of water quality was significant between in deep well and in shallow well （ P 〈 0.05） ; This significance was also seen between during abundant water period and during scanty period （P 〈 0.05 ） ;The change of water quality was slightly （P 〉 0.05 ） Conclusion The findings indicated that separate water supply was mainly polluted by demestic sewage, so rural water resources protection, drinking water treatment and monitoring should be strengthened. The rate of deep well water meeting the standard terms was higher, which indicated that deep underground water should be popularized in improving rural drinking water.
