摘要
以2011年重庆市饮用水源地南彭水库及其下游敬老院断面水质监测结果为研究对象,用模糊数学综合评价模型进行综合评价,结果表明:南彭水库水质较好,2月份水质最好,为I类,影响水质的主要因子为高锰酸盐指数与溶解氧。敬老院断面评价结果均为V类,主要污染因子为氨氮和总磷。两断面水质均能满足水域功能要求。
The paper seeks to evaluate drinking water quality employing fussy comprehensive evaluation method. Water quality of Nanpeng reservoir , which is one of drinking water sources , and Jinglaoyuan section in Huaxi tributary in 2011, have been assessed and rated . The results show that the water quality of Nanpeng reservoir in February, is rated grade I for surface water standard . The major influencing factors for water quality present to be permanganate index and dissolved oxygen. While the water quality o~ Jinglaoyuan section in Huaxi tributary merely meets grade V ,with ammonia nitrogen and total phosphorus appear to be major influencing pollutants. In addition both sites comply with requirement for water quality.
