摘 要：
于2011年3月在永定新河下游布设7个监测站位,选取pH、DO、COD、重金属和营养盐等12个水质因子作为评价指标,运用单因子指数评价法与内梅罗指数评价法对永定新河下游水质进行评价。结果表明,永定新河下游主要的污染因子是DO;主要的污染站位是唐津高速公路桥下和北塘排污河流入永定新河的一侧;其他站位的各项指标均达到《地表水环境质量标准》中的第V类标准,可以作为农业用水区及一般景观要求水域。通过数据对比,发现永定新河在2年内水质有明显的好转,说明近年来水环境治理工作起到了很好的成效。

摘 要：
Seven monitoring sites were set up in the downstream of Yongding new river in March 2011,and twelve water quality factors were selected as the evaluation indice,such as pH,DO,COD,heavy metals and nutrients.The single factors index method and Nemerow index method were used to analyze the downstream water quality.The results showed that the main pollution factor of Yongding downstream were DO.The main pollution sites are on one side of the Yongding new river near the sewage gate between Tang Jin Highway Bridge and Beitang sewage.The water quality index in other sites all fit for the surface water environment quality V standards,indicating that the water in this area can be used as agricultural waters and general landscape request waters.Through data comparison,it was found out that Yongding new river water has been greatly improved during the two years,indicating that the water treatment work has achieved remarkable results.
