| 摘 要： | 污染物衰减系数是反映河流水质污染变化情况、建立水质模型、计算水环境容量的重要参数之一,其确定的合理性直接影响到水环境容量以及水质模型的可靠性。通过查阅有关文献,概述了国内外部分河流的COD和BOD以及氨氮的衰减系数,并分析了影响污染物衰减系数的主要因素,为研究河流水体自净规律、计算水环境容量、区域排污总量控制计划的制定提供科学依据。

| Abstract: | Degradation coefficient of organic pollutant is one of the most important parameters,which can reflect the water quality.And it can be used to develop the water quality models and to calculate the water environment capacity.Its rationality directly affects the reliability of water environment capacity and water quality models.The degradation coefficients of COD,BOD and NH3-N in some rivers at home and abroad were summarized.And the main factors controlling degradation coefficient of organic pollutant were analyzed.It will be helpful for studying river self-purification rules,calculating the water environment capacity and making plan of controlling the total discharge quantity of pollutants. |
