摘要/Abstract

摘要： 对冰封期河流中化学耗氧量（COD）削减问题进行了研究，提出冰层的冻结对COD的削减作用. 给出沉淀作用、生物降解及冰层的冻结对河流中COD的削减模型. 实例分析结果表明，冰封期河流冰层的冻结对有机污染物的削减作用不能忽略.

关键词: 冰封期, 河流, 削减模式, COD

Abstract: The attenuation of chemical oxygen demand(COD) in rivers during the i cebound season was examined, and how the freezing action of ice-layer worked on the attenuation of COD was presented. The reduction model of COD in rivers by precipitation, biodegradation and freezing action of ice-layer was put forward. Via living example analyses, it should be concluded that the attenuatio n of organic pollutants operated by freezing action of ice-layer on rivers durin g the icebound season couldn’t be ignored.

Key words: icebound season, river, reduction mode, chemical oxygen demand
