Research on The Management of Thermal Discharge by Coastal Power Plant

With the quick development of power plant industry, the effect quantity of thermal discharge incearses gradually and so dose its on water enviormnent. But it doesn´t have special criterion of the warm water drainage at present. Based on the comprehensive summary of the progress in related area and the present situation of the warm water in our country, the paper indicates our country environmental management´s problems of the warm water. Take the Qingdao power plant for example. Two dimensional model of the transport and diffusion for the warm water is established. According to this numerical model, the concentration distribution of the warm water in the warm water drainage and the area of its influence are numerically predicted. Analyze the effects on ocean ecosystem brought by the warm water. Finally, propose strategy in management of warm water and utilization of waste heat.
