在所建潮流场的基础上,建立了八所近岸海域拉格朗日余流模型及乎流——扩散输运模型。预测八所污水集中排海对海域水质的影响,选COD为有机物污染的指标因子,经多方案比较,提出推荐位置及相应位置下的最大允许排放量。

Based on the calculated tidal current field, this paper constructs a Lagrangian residual current model and a convection- dispersion model, predictes the distribution of concentration when the sewage of Basuo is discharged concentratively, and chooses COD as the index factor of organic pollutant. Through comparison of many programs, the authors recom-mende the position of outlet and its maximum permitted discharge amount.
