目的:了解南平市城乡生活饮用水卫生状况,为提高饮用水卫生管理质量提供科学依据。方法:对2008年-2010年南平市城乡集中式供水和分散式供水的水质检测资料进行统计、分析和评价。结果:三年共检测样品689份,合格率为68.2%。其中集中式供水水样586份,合格率为80.9%;分散式供水水样103份,合格率为49.2%,集中式供水水样合格率与分散式供水水样合格率比较有显著性差异。水源水、山泉水和井水中合格率最低的是细菌总数和总大肠菌群。出厂水和末梢水各项目的合格率均在93.9%以上。结论:集中式供水水样合格率明显高于分散式供水水样的合格率;水源水、山泉水、井水是影响我市城乡饮用水合格率的主要因素;提高水质净化处理技术,加强水源地管理是保证饮水安全的关键。
Objective: To understand the sanitary status of drinking water in urban and rural areas in Nanping and to provide scientific basis for improving the quality of drinking water health management. Methods: Statistics, analysis and evaluation of the water quality testing data of centralized and decentralized water supply in urban and rural areas of Nanping from 2008 to 2010 were conducted. Results: A total of 689 samples were tested in three years with a pass rate of 68.2%. Among them, 586 were centralized water samples, with a passing rate of 80.9%; 103 distributed water samples with a pass rate of 49.2%. The passing rate of centralized water supply samples was significantly different from that of decentralized water supply samples. Source water, spring water and well water, the lowest pass rate is the total number of bacteria and total coliform bacteria. The qualified rate of the factory water and the peripheral water projects are all above 93.9%. Conclusion: The qualified rate of centralized water sample is obviously higher than that of decentralized water sample. Source water, spring water and well water are the main factors affecting the qualified rate of drinking water in urban and rural areas in our city. Water purification technology, Management is the key to ensuring drinking water safety.
