福建东山湾水质状况分析与污染防治对策

Analysis on the water quality state and the countermeasures for the pollution control in Dongshan Bay of Fujian

该文以DIN(无机氮 )、PO3-4 P、COD和DO为化学指标参数 ,分析 1 994～ 1 998年东山湾海域有机质污染和营养类型。结果表明 ,东山湾湾顶区水质总体上属于中度污染 ,内湾区属于轻度污染 ,水体 30 %时段处于富营养化状态 ,PO3-4 P是主要污染因子。根据污染特征 ,分析了影响水质的因素 ,并在此基础上 ,提出相应的防治措施。

The organic polluted state and nutrient type were studied at the Dongshan Bay in 1994～1998. Dissolved inorganic nitrogen, dissolved inorganic phosphorus, chemical oxygen demand and dissolved oxygen were determined. The results showed that the polluted condition in the top the sea area of the bay was at the middle level, and the other was low. 30% of water period was the eutrophic condition. The dissolved inorganic phosphorus was the key pollution factor. According to the features of the pollution, the factors affected were discussed. Based on these, the countermeasures for the pollution control were proposed.
