| 摘 要： | 2007年4月-2009年4月对上海白莲泾河段水体环境质量进行了调查,取黄浦江南码头上1个断面和白莲泾上的3个断面,于每月大、小潮当日采集各断面水样,获得了该河段的各项水质指标。2007年10月,白莲泾河道断流,泵闸工程实施。根据监测结果,以DO、BOD5、CODMn、TN和TP为指标参数,利用标准类别指数评价法对建闸工程施工活动的环境影响进行评价,结果发现:TN、TP是白莲泾河段的最主要污染指标,TN的权重系数均超过40%,甚至50%,均为劣Ⅴ类;TP的权重系数均超过10%,甚至30%,其含量是地表水Ⅳ类标准的0.8~5.6倍。总体上,白莲泾河段3个站点的水质劣于黄浦江站点,而施工前水质优于施工后。施工前,大潮期白莲泾河道IV类水比例为29%,较小潮期(8%)高出21%。建闸施工后,大小潮期间出现劣V类水的比例分别为87%和88%,潮汐对白莲泾河段并无显著影响。

| Abstract: | The investigation on water quality of Bailianjing reach in Shanghai was carried out from April 2007 to April 2009.One cross-section at South Ferry of Huangpu River and three cross-sections at Bailianjing River were chosen and the survey covered both the spring and neap tides throughout the years.The damming of pump-gateway engineering on Bailianjing River was started in October 2007.Five water quality parameters which were dissolved oxygen (DO) , biochemical oxygen demand (BOD5) , permanganate index (CODMn) , total nitrogen (TN) and total phosphorous (TP) , were used to calculate the standard category index of 4 cross-sections.The results showed that the most important pollutants were TN and TP.Weight coefficients of TN in excess of 40% or even 50%, were over V grade and didn''t meet the corresponding water quality standard.Weight coefficients of TP were more than 10% or even 30%, and TP content was 0.85.6 times as high as National Grade IV.In general, water quality of three sites at Bailianjing River was inferior to that of Huangpu River, but the pre-construction water quality was better than building sluiced.Before pump-gateway was constructed, the proportion of IV grade water in Bailianjing River during spring tide period was 29%, 21% above that during neap tide period (8%) .After pump-gateway engineering started, the percentage of the water grade worse than V during spring and neap tide periods was 87% and 88%, showing that tides did not have any noticeable effect on Bailianjing River. |
