目的：了解大足区农村饮用水水质卫生状况，为改善和提高农村饮用水质量提供依据，促进农村改水事业的发展。方法：根据每年饮用水监测方案按照国家标准于2010-2014年枯水期（4）、丰水期（8）进行水样的采集、检验和评价。结果：2010-2014年共检测水样444件，合格282件。其中，水质合格率2010年9.6 %、2011年27.3%，2012年60.3%，2013年80.0%，2014年92.0%，2014年最高，20 10 年最低，丰水期高于枯水期，差异均有统计学意义（P≤0.05）。在各项检测指标中，微生物指标、感观指标和消毒指标不合格率高，毒理学指标全部合格。结论：近5年来，我区农村饮水在水源保护、工程设计与管理上都有了长足进步，但总体水质合格率偏低。各相关单位应完善农村饮用水的监督管理，注重人员培训，强化饮用水消毒工作，以保障农村生活饮用水安全。
Objective: To understand the sanitary status of drinking water quality in rural areas in Dazu District and provide basis for improving and improving drinking water quality in rural areas to promote the development of rural water diversion project. Methods: According to the annual drinking water monitoring program in accordance with national standards in the 2010-2014 dry season (4), wet season (8) for water samples collected, test and evaluation. Results: From 2010 to 2014, a total of 444 water samples were tested, of which 282 were qualified. Among them, the water quality pass rate was 9.6% in 2010, 27.3% in 2011, 60.3% in 2012, 80.0% in 2013, 94.0% in 2014, the highest in 2014 and the lowest in 2010. The wet season was higher than the dry season, with statistical differences Significance (P≤0.05). Among the testing indexes, the microbe index, the sensory index and the disinfection index failed with high pass rate, all the toxicological indexes were qualified. Conclusion: In the recent five years, rural drinking water in our district has made great strides in water source protection, engineering design and management, but the overall water quality passing rate is low. Relevant units should improve the supervision and management of rural drinking water, pay attention to personnel training, and strengthen the disinfection of drinking water to ensure the safety of rural drinking water.
