摘要
运用平流输运扩散模型对大连市马栏河污水排海工程岸边排放和深水排放的海水水质进行预测,分析比较了两种排放方式的水质状况。结果表明,与同等排放量岸边排放方式比较,在经一级处理深水排放情况下,受纳污水水体的海水质量状况大大改善,符合海洋功能区划(二类水质标准)的要求,混合区面积大大小于《污水海洋处置工程污染控制标准》(GWKB4-2000)对混合区范围的要求。
Based on the advection-dispersion model, the seawater quality discharged into the shore and offshore of Malan River in Dalian was simulated. The two ways discharged were analyzed and compared. The results showed that the seawater quality would be improved overly after first disposed and long-dated deep water discharged. The seawater quality could be reached the requirement of the division of marine functional region（ the second class water quality criterion）. The commixed zone is much smaller than that in the sewage dispose project accord with the pollution control criterion.
