目的了解龙泉驿区农村饮用水卫生现状,为农村改水工作提供科学依据。方法调查农村水厂水处理工艺,采集集中式供水、分散式供水、水源水进行实验室检测,对检测结果进行分析。结果平原区集中式供水水质优于丘陵区集中式供水,两者合格率分别为100%和71.4%,差异有统计学意义(χ2=13.714,P=0.000);丘陵区集中式供水水质优于丘陵区分散式供水(井水),两者合格率分别为71.4%和10%,差异有统计学意义(χ2=11.121,P=0.001)。按月份分析,6月、8月农村集中式供水合格率最低,主要不合格指标为微生物指标和消毒剂余量指标。结论龙泉驿区集中式供水水质平原地区优于丘陵地区,丘陵地区井水合格率最低,丘陵区的农村饮用水安全保障应作为龙泉驿区农村饮水安全工作的重点。
Objective To understand the sanitary status of drinking water in rural Longquanyi district and provide a scientific basis for water diversion in rural areas. Methods The water treatment technology in rural waterworks was investigated. The centralized water supply, distributed water supply and water source water were collected for laboratory testing, and the test results were analyzed. Results The water quality of centralized water supply in plain area was better than centralized water supply in hilly area, with the pass rates of 100% and 71.4% respectively (χ2 = 13.714, P = 0.000). The centralized water quality in hilly areas was better than Hilly distributed water supply (well water), the passing rate of 71.4% and 10%, respectively, the difference was statistically significant (χ2 = 11.121, P = 0.001). According to the monthly analysis, the qualified rate of centralized water supply in rural areas was the lowest in June and August, and the main unqualified indicators were the indicators of microbial and residue of disinfectant. Conclusion The centralized water quality plain area of Longquanyi District is superior to the hilly area, and the lowest qualified rate of well water in hilly areas. The rural drinking water safety guarantee in the hilly area should be the focus of rural drinking water safety in Longquanyi District.
