摘要
依据《地表水环境质量标准》(GB3838-2002),采用单因子评价方法,分别对小浪底水库建成前3年和建成后4年的河道水质进行评价,结果表明,小浪底水库建成后,在库首断面水质持续恶化的情况下,小浪底坝下水质状况却明显好转,说明小浪底水库库水对原水污染物有较强的净化能力,从而使下游河段水质得到改善。
According to “Surface Water Environment Quality Standard”(GB3838-2002),it was evaluated the riverway water quality of Xiaolangdi Reservoir 3 years before its completion and 4 years after its completion,using the single factor evaluation method.The result indicated that after the completion of Xiaolangdi Reservoir completed,although the water quality in the reservoir head section continuously changes for the worse,yet that below the dam obviously changes for the better.Which shows that the water in Xiaolangdi Reservoir has a strong ability for purifying the pollutants of the original water,thus improving the water quality of downstream reach.
