摘要
通过对白石水库及其入库河流水质的长期的监测,依据国家相关标准,对白石水库水质进行了评价分析.评价结果表明,入库河流水质为超V类水体,主要的超标污染物为CODcr、BOD5、氨氮、总氮以及铁、锰;水库现状水质总体状况尚好,属轻度污染水质类型;在水库中心区和坝前区,除总氮为Ⅳ类水质外,在取水口处除石油类和磷为Ⅳ类水质外,其余项目均达到或优于Ⅲ类水质;白石水库可以作为城市生活饮用水水源,但必须采取一定的强化净化工艺处理,满足国家生活饮用水水质卫生标准.针对污染原因,建议采取有效的污染治理和生态环境保护措施,改善白石水库水质,达到作为集中式生活饮用水水源地二级保护区的水质标准.
The present water quality of Baishi reservoir has been estimated after a longtime monitor for the water quality of Baishi reservoir and its joint river according to the corresponding national standard.The result of estimation indicates that the water quality of the joint river exceeds the level V and the main exceeding contamination are COD(Cr),BOD5,ammonia and nitrogen,total nitrogen,iron and manganese.The quality of present water is fine,which is at light contaminative level.In the center of reservoir and front dam,all the other items either reach or excel the water quality standard Ⅲ except that the total nitrogen level of water and the petroleum and phosphor level of water in waterabsorption is Ⅳ.Baishi reservoir can be used as the source of urban drinking water,but it must be decontaminated to satisfy the national sanitation standard of drinking water quality.An effective treatment of contamination and a protective measure for ecological environment should be adopted to improve and assure the water quality of Baishi reservoir in order to reach the standard required as a secondary conservation of drinking water source.
