摘要
温排水来源于电厂汽轮机的冷却用水,具有温度高、排量大、持续排放等特点,排入近岸海域随水流扩散,会形成水平、垂直方向的流速和温度分布,其夹带的余热引起海水温升,对海洋生物造成影响。研究表明,温排水对海洋生物如鱼类、浮游动植物、底栖动物等造成影响,改变其生存、生长和繁殖的自然环境,同时它损害海洋生物的多样性。
Thermal discharge with the characteristics of high temperature, large displacement and conti-nuous discharge, is derived from the cooling water of steam turbine in power plant. It will diffuse along the flow when discharged into offshore area, and then form the certain distribution of velocity and temperature in both horizontal and vertical direction. The waste heat of thermal discharge increases the temperature of sea water, which affects marine organism. Researches show that thermal discharge affects marine organism such as fish, zooplankton and phytoplankton, zoo benthos, through changing their natural environment for survival, growth and reproduction;meanwhile, thermal discharge also damages the biological diversity of Marine organism.
