目的:了解我市农村饮用水工程水质卫生状况,掌握水质动态变化,为改善农村饮用水质量提供依据。方法:选择我市具有代表性的四个县的供水工程水点,于枯水期及丰水期,对水源水及末梢水中色度、浊度、pH等20个项目进行检验。结果:全年检验水样300份,色度、pH、氨氮、铁、锰、砷等项目均合格,其余项目有不同程度超标,其主要超标指标是感官和微生物。结论:我市农村饮用水污染严重,主要问题是水源管理不善,无水处理设施及消毒措施。存在经饮用水传播疾病的潜在性危险,影响农村人群身体健康,需认真加以改进。
OBJECTIVE: To understand the sanitary status of drinking water projects in rural areas in our city, to grasp the dynamic changes of water quality and provide the basis for improving the drinking water quality in rural areas. Methods: Water supply water points in four representative counties in our city were selected. During dry season and wet season, 20 items of water color, turbidity and pH in water source and peripheral water were tested. Results: 300 samples of water samples were tested throughout the year. The items such as color, pH, ammonia nitrogen, iron, manganese and arsenic were all qualified. The remaining items exceeded the standard in varying degrees. The main indexes exceeding the standard were sensory organs and microorganisms. Conclusion: The drinking water in rural areas of our city is seriously polluted. The main problems are poor water management facilities, non-water treatment facilities and disinfection measures. There is a potential danger of disease transmission through drinking water, which affects the health of rural people and needs to be seriously improved.
