摘　　要：目的通过对2015-2018年秦皇岛市抚宁区农村生活饮用水监测结果进行分析,了解居民饮用水水质情况,找出存在的安全隐患,为今后农村饮用水的改善、发展方向及政府制定相关政策提供依据。方法监测点覆盖全区所有乡镇,在每个乡镇采取单纯随机方式设置监测点。每年枯水期、丰水期各采样一次。水样的采集、运输、检验均按照GB/T 5750-2006进行,检测结果按照GB 5749-2006进行评价。结果水质总合格率为43.8%。不合格指标主要为总大肠菌群、菌落总数、氟化物、氯化物、溶解性总固体、总硬度、硝酸盐。结论农村饮用水以地下水为主,饮用水水源周边环境差,对水源保护意识淡薄,饮用水出厂前不进行消毒处理是不合格的主要原因。需加强水源的保护,完善水质卫生监测体系和水处理工艺。Objective To analyze the monitoring results of rural drinking water in Funing District of Qinhuangdao City from 2015 to 2018,to understand the situation of drinking water quality and the hidden danger of safety,and to provide a basis for the improvement and development direction of drinking water in rural areas and the formulation of relevant policies.Methods The monitoring points covered all the townships in the whole district,and they were set up in each township with simple random sampling methods.Water sampling was carried out once a year in dry season and wet season.The collection,transportation,and inspection of water samples were conducted according to GB/T 5750-2006,and the testing results were evaluated according to GB 5749-2006.Results The total qualified rate of water quality was 43.8%.The unqualified indicators mainly included total coliform flora,total number of colonies,fluoride,chloride,total soluble solids,total hardness,and nitrate.Conclusion Rural drinking water is mainly groundwater whose surrounding environment is poor.Residents have a weak consciousness of water source protection.And no disinfection before the factory is the main reason for unqualified drinking water quality.It is necessary to strengthen the protection of water sources,improve the water quality sanitation monitoring system and water treatment technology.
