| 摘 要： | 珠江广州河段10多a来的水质监测数据表明,BOD5不高,但DO较低.这种特征至今仍未改变,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.

| Abstract: | The data of more than 10 years have shown that the BOD-5 is not high but DO is low in the Guangzhou Reach water body of the Pearl River.So far this feature has not changed and there are even occasions of darkening and stinking in partial water body.The reasons of water pollution are analyzed from the point of view on the oxygen consumption,degradation of pollutants,oxygen balance of water and hydrographic condition,etc. |
