摘要
采用单因子评价法和内梅罗指数法对海宁市第二水厂水源水质进行了综合评价.单因子评价结果显示,2017年3个监测断面中高锰酸盐、溶解氧、氨氮和五日生化需氧量指数基本符合Ⅲ类水标准,总磷轻度污染.内梅罗指数法评价结果表明,2013—2017年,3个断面平均PIp值由1.841降低为1.134,泰山桥水厂由Ⅳ类转为Ⅲ类水质,杭申公路桥和丰士水泥厂桥虽暂未达到Ⅲ类水质的标准,但污染呈下降趋势,水质显著提高.
The water resource quality of Haining Second Water Plant was monitored and evaluated by using the single factor evaluation method and the Nemerro index method.The results of single factor evaluation showed,the permanganate index,dissolved oxygen,ammonia nitrogen and five days biochemical oxygen demand(BOD 5)of the three sections in 2017 met the classⅢstandard.The total phosphorus pollution was light.The evaluation results of the Nemerow index showed that the average PI p of three sections was reduced from 1.841 to 1.134 between 2013 and 2017.The water quality of Tai bridge was raised to classⅢfrom classⅣ.Although the water quality of Hangshen highway bridge and Fengshi cement factory bridge did not meet the classⅢtemporarily,which were improved significantly.
