摘要
本文应用二维水质数学模型,分析了舟山水产食品厂排污对沈家门港区水质影响的现状,并预估了新、老两厂同时运行后港区水质污染的程度。 计算结果表明,沈家门港内污染物质主要靠潮流的稀释和输移。在此狭长的水道内,水流沿纵向流动,横向水体交换少,以致污染物沿横向不易弥散。污水沿岸排放后,高浓度污染带紧贴岸边随涨落潮流往复移动,对水道内水质有一定影响。
By solving two-dimension water quality maths equations, the author analyses the influence of polluted water from Zhoushan Aquatic Food Product Factory on the water quality of Shenjiamen Hafrbour before renewing project and predicts water quality in the Harbour due to the polluted water from the new and old factory after renewing project.
The calculating results demonstrate that the dilution and transportation of the pollutant depent mainly on tidal current in Shenjiamen Channel. And in this narrow channel the transversal velocity is very small so that it is not easy for pollutant to dilute along the transversal direction. Therefore, if the polluted water from the factory drains away on the bank, a belt near the bank moves up and down with flood and ebb, and has some influence on the water quality in the channel.
