胶州湾海域水质预测

PREDICTION OF WATER QUALITY IN JIAOZHOU BAY

在已建潮流模型的基础上,用ADI法建立了胶州湾扩大域变动边界的平流—扩散输运模型,以COD为指示因子,预测了胶州湾海域1995年、2000年的水质、青岛环海公路海上段、沧口区北半部污水截流、北水南调、集中排放以及胶州湾西部经济开发对海域水质的影响等。为青岛市环保部门制定环保规划提供决策依据。

Based on the established tidal current model, this paper uses the ADI numerical method to establish a varied-boundary convection-dispersion mass transport model in the extended Jialzhou Bay area. Using COD as the indicator of pollutant, it predicts the water quality of Jiaozhou Bay in 1995 and 2000, and the impact on the water quality caused by the Round the Sea Highway, the sewage blocking in northern Cangkou district, the project of sending waste water from the north to the south, concentrated discharge, and the economic development west of Jiaozhou Bay etc. It provides the Environmental Protection Department of Qingdao with a basis for making decisions in to working out environmental protection plans.
