| Abstract: | The attenuation of chemical oxygen demand(COD) in rivers during the icebound 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 attenuation of organic pollutants operated by freezing action of ice layer on rivers during the icebound season couldn't be ignored. |
