| 摘 要： | 在讨论常规的沉淀、生物降解模型在冰封期应用的基础上,进一步给出了冰冻作用损耗模型.实例分析结果表明,在冰封期,河流中化学需氧量(COD)的损耗方式以沉淀和冰冻作用为主,而生物降解作用则相对较弱.

| Abstract: | Research on the reduction of pollutants in rivers during freezing period is just at the beginning stage in China.Frozen in the ice is a special way of pollutant reduction.Models of deposition and biodegradation are summarized and applied to the freezing period rivers.Furthermore,the model for estimating pollutant frozen in ice is presented.Example analysis shows that deposition and frozen in ice are the main manners for organic pollutant reduction during freezing period.The action of biodegradation is minor. |

| Keywords: | freezing period pollutant reduction deposition biodegradation frozen in ice |
