摘　　要：目的了解右江隆安河段河水污染现状、隆安备用水厂水质卫生状况,为进一步加强水源和水厂的卫生管理提供依据。方法现场调查和实验室检查。结果检测3份隆安不同河段河水,总氮分别为0.78mg/L、1.45mg/L和0.96mg/L,为Ⅲ-Ⅳ类水;23∶50采集的隆安备用水厂水源水氨氮1.30mg/L,为Ⅳ类水,出厂水氨氮0.72mg/L,氨氮超出国家标准0.44倍,出厂水仍不合格。结论右江隆安河段河水有机物污染较严重,不能作为集中式生活饮用水水源,必须加强对隆安河段河水和备用水厂的水质监督监测。Objective To understand the pollution status of Long＇an reach of Youjiang River,and the water quality and hygiene condition of Long＇an reserve waterworks,provide basis for strengthening quality-control work of the source and waterworks.Method Using field investigation and laboratory examination method.Results 3 samples from different reaches of Long＇an river were tested,the total nitrogen were 0.78mg/L,1.45mg/L and 0.96mg/L respectively,water grades were Ⅲ-Ⅳ.At 23∶ 50pm,the ammonia nitrogen of source water in Long＇an reserve waterworks was 1.30mg/L,which was grade Ⅳ,the ammonia nitrogen of output water was 0.72mg/L,the ammonia nitrogen surpassed national standards 0.44 time,the produced water was still unqualified.Conclusions Water in Long＇an reach of Youjiang river was polluted seriously by organic matter,which cannot use as the central water supply source.We need to further strengthen water quality monitoring of Long＇an reach of Youjiang River and Long＇an reserve waterworks.
