目的了解田东县市政供水、二次供水和农村饮用水安全卫生水平,为改善饮用水卫生环境,预防控制介水性传染病,保障广大人民群众饮水安全提供科学依据。方法根据《2014年广西生活饮用水卫生监测工作方案》、国家标准《生活饮用水卫生标准》和《生活饮用水标准检验方法》等要求进行布点、采样、监测,对监测数据进行分析、比较。结果共采集116份水样品进行检测,合格71份,总合格率61.2%。城市生活饮用水、农村生活饮用水合格率分别为85.7%、47.3%;集中式供水、二次供水、小型集中式供水、分散式供水的检测合格率分别为81.8%、90.0%、50.0%、0.0%。结论微生物污染是饮用水水质安全的潜在危险因素,城市饮用水卫生状况优于农村饮用水,集中式供水和二次供水优于小型集中式供水和分散式供水。工作重点应放在农村饮用水的卫生监督管理和小型集中式供水分散式供水的净化、消毒处理工作上。
Objective To understand the municipal water supply, secondary water supply and rural drinking water safety and hygiene standards in Tiandong County, providing scientific basis for improving the sanitary environment of drinking water, preventing and controlling waterborne infectious diseases and ensuring the drinking water safety of the broad masses. Methods According to the “2014 Guangxi drinking water health monitoring program of work”, the national standard “drinking water health standards” and “drinking water standard test methods” and other requirements of distribution, sampling and monitoring, the monitoring data analysis and comparison. Results A total of 116 water samples were collected for testing, of which 71 were qualified, with a total pass rate of 61.2%. The passing rates of urban drinking water and drinking water in rural areas were 85.7% and 47.3% respectively. The passing rates of centralized water supply, secondary water supply, small centralized water supply and distributed water supply were 81.8%, 90.0% and 50.0% respectively, 0.0%. Conclusion Microbial contamination is a potential risk factor for drinking water quality and safety. Drinking water in urban areas is superior to drinking water in rural areas. The centralized water supply and secondary water supply are superior to small centralized water supply and decentralized water supply. Work should focus on the health supervision and management of rural drinking water and small centralized water supply and distribution of water purification, disinfection work.
