水库水体底质界面污染物交换的熵描述

Entropy Description for Pollutants Exchanging Across the Water Sediment Interface in Reservoirs

针对水库底质中污染物易向上覆水体释放形成二次污染的问题，提出了水库底层水体与底质之间污染物交换的浓度熵理论．给出了底质和水体中污染物质迁移的浓度熵流和熵产生的数学描述式．

The exchange of pollutants across the water sediment interface is the main reason causing a secondary contamination in reservoirs. In this paper, the theory of entropy for the exchange of pollutants between water and sediments is put forward. The mathematical expressions of the entropy flow for the transport of pollutants across the water sediment interface and the entropy yields within both water body and sediments are given.
