| 摘 要： | 根据延河主干河段排污现状，以ＢＯＤ５为指标，估算了进入河流的生活污水和工业废水负荷，并运用稳态一维ＢＯＤ５降解模型进行了分析计算，得出延河主干河面的河流综合自净系数为Ｋ＝２．６９，说明延河这样的高含沙量河流具有很强的有机污染自净能力，对２０１０年的河流水质预测表明，为保证延河水质达标，必须采取有效的措施控制生活污水和工业废水排放。

| Abstract: | The pollution loads of domestic and industrial wastewater were calculated according to the current condition of pollutant discharged to the main reach of the Yanhe River. The one dimensional steady state BOD 5 decomposition model was applied for pollution analysis. It was estimated that the coefficient of self purification was as high as 2.69, showing the high capacity of organic decomposition of the high turbidity river. The river water quality was also predicted for the year of 2010, and the results indicated the need of effective control of domestic and industrial wastewater pollution to meet the water environmental standard. |
