| 摘 要： | 根据2009年常州市老运河及支流（污染企业）的水体污染物调查资料,分析了老运河的水质状况,并计算了各河段的氨氮通量。由氨氮通量确定各支流（污染企业）的氨氮贡献。结果表明,关河西段对老运河全程氨氮浓度上升的贡献率最高,占38.9%,其次是凤凰河,江苏新亚化工有限公司对老运河全程氨氮浓度上升的贡献率占9.2%,其余污染企业对老运河的氨氮贡献率均甚小。最后在分析主要支流污染来源的基础上,提出了防治水污染的相应对策和建议。

| Abstract: | Based on the investigation data of water pollutants in the old canal and tributaries,the water quality of the old canal was analyzed.Additionally the ammonia-nitrogen flux in every reach was calculated,by which the ammonia-nitrogen contribution of every tributaries(polluting plants) was determined.The results showed that the west section of Guan River did the most contribution,accounting for 38.9%.The next contribution came from Fenghuang River,where located the Jiangsu Xinya Chemical Co.,Ltd.,accounting fo... |
