黄浦江上游水源地水质污染分析与突发性水污染事件分级

对2007-2010年黄浦江上游水源地水质调查数据进行分析后认为：NH3-N和CODMn污染主要来自其上游的淀山湖及省界来水，淀山湖、拦路港斜塘及黄浦江上游主干水质污染程度有逐年降低趋势，淀山湖尤为明显，黄浦江几大支流依据污染程度排序为大泖港〉园泄泾〉斜塘〉太浦河；黄浦江原水中的NH3-N和CODMn可以通过臭氧＋生物活性炭的深度处理工艺有效降低，使出厂水水质达标；移动源污染（船舶）已成为黄浦江水源地最难以控制的污染源之一，并成为原水供应最主要的风险；建议将黄浦江上游水源地区域内外发生的突发性水污染事件分为四级，并提出相应的分级标准。

Analysis of Water Quality Pollution and Classification of Accidental Water Pollution Events in Upstream Water Source of Huangpu River

The analysis of water resource area of the Huangpu River from 2007 to 2010 show that the pollution of NH3-N and CODM, are mainly from Dianshan Lake and provincial boundaries. The pollution degree has dropped yearly in Dianshan Lake, Xietang River and the mainstream of Huangpu River, particularly in Dianshan Lake. Among the main tributaries, Damaogang River is the worst polluted river, which follows Yuanxiejing River, Xietang River and Taipu River on the basis of the pollution degree. NH3-N and COD~ in raw water of Huangpu River can be removed effectively by O3-BAC process so that the finished water meets the drinking water standards well. Pollution from moving sources of pollution, especially ships, has become one of pollution source hardly con- trolled. Classification of accidental water pollution events in upstream water resource area of the Huangpu River was suggested, and the standard of classification was proposed.
