摘要
珠江广州河段水体中BOD_5不高而溶解氧较低的特征,10多年来没有改变,甚至发展到局部水质出现发黑发臭的现象。文章从污染物耗氧、污染物降解能力、水体氧平衡和水文条件等方面剖析这种水质污染的原因,进而提出解决广州河段水污染控制的有效途径。
There were low dissolved oxygen and not high BOD_5 in Guangzhou Reach water of Pearl River. This feature was no many changes in the past 10 years and even happened the darkening and smelling in partial water. The reasons of water pollution were analyzed from the point of view on oxygen demand and decomposition capability of pollutant, oxygen balance in water and hydrology. The available ways to control this kind of pollution were discussed.
