农村生活饮用水监测结果分析

目的了解农村生活饮用水卫生状况,为保障供水质量、居民饮水安全和防病效果提供依据。方法选择有代表性的监测点进行调查和水质监测,采样、检验及评价方法按照GB/T 5750—2006、GB 5749—2006。结果2018年调查54个监测点,覆盖人口为156735人,合格水质覆盖人口149910人,合格饮用水人口覆盖率为95.65%。全年采集108份水样(出厂水24份、末梢水84份),合格83份,水质总合格率为76.85%,其中枯水期合格率为87.04%、丰水期合格率为66.67%,枯水期水质合格率高于丰水期;水质共检测3720项,合格3646项,项目合格率为98.01%,其中城关检测420项,合格率为100.00%,农村检测3300项,合格率为97.76%。结论生活饮用水的水质状况及管理情况总体良好,但仍存在一些不合格,特别是农村小水厂及分散式供水点,在管理方面有待于进一步提高。应加强饮用水安全和防病知识的宣传,预防介水传染病的发生。

Analysis of rural drinking water monitoring results

Objective In order to understand the sanitary conditions of drinking water in rural areas and provide basis for drinking water quality,safety and disease prevention.Methods Representative points were selected for investigation and water quality monitoring,sampling,inspection and evaluation according to GB/T 5750—2006 and GB 5749—2006.Results A total of 54 monitoring points were surveyed in 2018,covering 156735 people.The qualified water covered 149910 people,and the coverage rate of qualified drinking water was 95.65%.108 water samples were collected throughout the year(24 samples of factory water,84 samples of ending water)and 83 samples were qualified.The total qualified rate was 76.85%,including 87.04%in dry season and 66.67%in wet season.The pass rate of water quality in dry season is higher than that in high season.A total of 3720 water quality tests were conducted and 3646 were qualified.The qualified rate of water quality project was 98.01%.Among them,420 items were tested in urban areas,with the passing rate of 100.00%,and 3300 items were detected in rural areas,with a passing rate of 97.76%.Conclusion The quality and management of drinking water in our county is generally good,but disqualification still exists,especially in small rural water plants and decentralized water supply points.The management needs to be further improved.It is necessary to strengthen the propaganda of drinking water safety and disease prevention knowledge to prevent the occurrence of infectious diseases.
