为了清晰理解湛江湾内某电厂脱硫酸性废水排放入海后的时空输移路径,及其引起海水pH变化的空间影响范围,应用ECOMSED海洋模式模拟该电厂近岸海域的水动力过程和脱硫酸性废水排放引起海水pH变化的空间影响范围.模拟结果显示:湛江湾海域潮汐特征为不规则半日潮,潮流基本沿航道深槽呈往复运动,大潮涨潮过程流速介于0.8~0.9 m·s-1之间,落潮过程流速在1.1~1.2 m·s-1之间;电厂脱硫酸性废水直排入海后随潮流呈带状输移,导致水体pH低于7.8的极端影响面积为30.70 km 2,占湛江湾海域面积16.2%.

To understand the space-time distributing and sea water pH changes with the acidic effluent from power plants draining into Zhanjiang Bay, the hydrodynamic processes of Zhanjiang Bay were simulated by ECOMSED. The changes of seawater pH were done also, the changes of which were caused by the acidic effluent discharge of power plant. The results of the simulation show that, the tidal characteristics were irregular semidiurnal tides in Zhanjiang Bay. The tidal processes were reciprocating along the waterway deep trench. The flow rate of raising tide was the range of 0.8~0.9 m·s-1. The flow rate of ebb tide was the range of 1.1~1.2 m·s-1. The acidic effluent of power plant was zonal transported by the tide in Zhanjiang Bay. The area with its extreme impact was 30.70 km2, accounting for the Zhanjiang Bay area of 16.2%.
