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。
Objective To learn more about the hygiene, safety and management of rural drinking water in Yizhou City. Methods According to the standards of Sanitary Standard for Drinking Water (GB 5749-2006) and Standard Test Method for Domestic Drinking Water (GB / T 5750-2006), respectively, during the wet periods of 2011 and 2012 (March and April) and dry season (July and August) Collection, inspection and evaluation of water samples from rural water quality monitoring points in Yizhou City. Results The qualified rates of microbial indicators of rural drinking water in Yizhou City in 2011 and 2012 were 18.10% and 52.50%, respectively, with statistical significance. The total number of centralized water supply colony, total coliform bacteria and heat-resistant coliform bacteria in 2011 were 67.39%, 25.00% and 27.17% respectively. The passing rates in 2012 were 86.11%, 50.94% and 63.89% respectively. The decentralized water supply of total coliform bacteria pass rate as low as 0.00%, heat-resistant coliform bacteria pass rate of only 3.85%, Conclusion Yizhou area of rural drinking water quality is serious, still need to improve and adhere to water quality monitoring and management.
