2011-2012年宜州市农村生活饮用水微生物指标检测结果分析

目的进一步了解宜州市农村生活饮用水水质卫生安全情况和管理水平。方法按照《生活饮用水卫生标准》（GB 5749-2006）和《生活饮用水标准检验方法》（GB/T 5750-2006）,分别于2011、2012年丰水期（3、4月）和枯水期（7、8月）对宜州市农村水质监测点进行水样的采集、检验和评价。结果 2011、2012年宜州市农村饮用水微生物指标合格率分别为18.10%和52.50%,差异有统计学意义。集中式供水菌落总数、总大肠菌群、耐热大肠菌群2011年合格率分别为67.39%、25.00%、27.17%,2012年合格率分别为86.11%、50.94%、63.89%。分散式供水总大肠菌群合格率低至0.00%,耐热大肠菌群合格率仅为3.85%,结论宜州地区农村生活饮用水的水质污染状况严重,仍需改进和坚持水质监测管理。

Rural drinking water microbial indicators detection results analysis of Yizhou city during 2011-2012

Objective To learn the sanitary condition and management level of drinking water in rural areas of Yizhou. Methods According to Drinking water standard for health（ GB 5749-2006） and Drinking Water Standard Test Methods（ GB / T 5750-2006）,water samples were taken,detect and evaluate during wet season（ March and April） and dry season（ July and August） in 2011 and 2012 respectively. Results In 2011 and 2012 the qualified rate of microbiological indicator were 18. 1% and 52. 50% respectively,and the difference was significant. The centralized supply system total bacteria,total coli form and thermo tolerant coli form bacteria were 67. 39%,25. 00% and 27. 17% respectively in 2011,and 86. 11%,50. 94% and 63. 89%,in 2012. The qualified rate of total coli form was 0. 00%,thermo tolerant coli form bacteria was 3. 85% of separated supply system. Conclusions The pollution of drinking water in this area is severe,drinking water quality monitoring management still need to improve and insist.
