| 摘 要： | 针对吉林市铁合金厂排污口下游江水的污染情况，设计研究江段，分段、分层取样。通过野外与室内实验，分析研宄了江水污染物的主要成分，并对NH4^ 的纵向、横向、垂向上的分布特征及其影响因素进行了详细研究。结果表明，垂直方向污染物扩散可以瞬时完成，在极短的时间内基本能达到完全混合；在横向和纵向上，岸边排放污染物一般只在近岸扩散，污染范围一般也只在靠近排污口一带；随着离排污口距离增大，污染物浓度降低，横向变化率较纵向大。本研究为排污口的污染物控制与治理、水资源保护提供了科学依据。

| Abstract: | The pollution situation of the downstream river water of the Second Songhua River at the drains of Alloy Iron Factory of Jilin City is studied in this paper. The water samples are adopted according to its depth and the river reaches. Field and indoor experiments are carried out and the primary compositions of pollutants in the river water are recognized. Longitudinal,transversal and vertical distribution characteristics and influence factors of NH4+ are analyzed,which provides liable basis for controlling and harnessing the pollutants of the drains. The results show that the pollutants can instantaneously diffuse and basically reach complete mixing in very short time. In the transversal and longitudinal directions,the pollutants discharged from the bank diffuse in the near bank and the pollution zone is near by the wastewater discharge outlet. The concentration of the pollutants decreases as the distance to the wastewater discharge outlet increases. The rate of the transversal change is higher than that of the longitudinal. The fact provides a scientific ground for the pollution control,harnessing and water resources protection. |
