摘　　要：采用二维有限元数学模型,对青岛碱厂白泥脱硫废水排放在胶州湾水动力作用下夏季和冬季不同温升的扩散范围进行了预测,并根据不同温升的影响范围分析评估对娄山河口附近海洋生物的影响情况。预测结果表明,白泥脱硫废水温升排放,在夏季影响较冬季小,夏季时温升超一、二类水质的面积为0.30 km2,离排放口的最远距离为0.78 km,没有超三、四类水质的水域;冬季时温升超一、二类水质的面积为1.24 km2,离排放口的最远距离为1.82 km,超三、四类水质的水域面积为0.35 km2,离排放口的最远距离为0.81 km。冬季温升较高,会对生态环境产生一定的不利影响。A two-dimensional finite element model was used to simulate tidal flow and temperature diffusion range of the desulfurization wastewater discharged by Qingdao Alkali Corporation,which was aimed at analyzing the influence of the thermal discharge on the marine organisms near Loushan Estuary.The analysis results show that the thermal discharge has a less influence in summer than that in winter.In summer,the area exceeding class I,II water quality standard is about 0.30 km2,and its farthest distance from the outfall is 0.78 km.There is no area exceeding class III,IV water quality standard.But in winter the area exceeding class I,II standard increases to 1.24 km2,and its farthest distance reaches 1.82 km.The area exceeding class III,IV in winter is 0.35 km2 with 0.81 m farthest distance from outfall.The temperature rise in winter is higher,which has unfavorable influence on the marine ecological environment.
