摘　　要：采用数值模拟的方法,计算和分析了上海市金山区水域无污水排放、放流管深海正常排放、岸边紧急排放和污水未经处理直接排放4种不同排放方式对纳污海域水质的影响。结果表明,在金山邻近海域的水动力条件下,上述4种排放方式中,岸边紧急排放对近岸海域的污染最严重。在事故排放这一最不利工况时,金山排海工程所选定的排放口,紧急排放对纳污海域环境的影响仍然是有限的,不会影响到小金山岛等敏感水域的水质。Wastewater marine disposal is a kind of technology that makes full use of huge dilution and assimilation capability of the ocean. Computation and analysis were made for four cases in Jinshan area of Hangzhouwan Bay by the numerical simulation method. The results showed that the effect on water quality was more significant in emergency case than the other three cases. According to analysis of the water quality near the outfall sea area, even in the most disadvantage case （accident discharge）, the effect was still quite limited and would not have influence on the sensitive area such as Xiao Jinshan Island.
