阐述了受纳水体热环境容量的内涵,提出了基于热环境容量评价指标与热环境容量模拟的滨海电厂温排放控制方法。以黄茅海海域为例,在潮流数值模拟基础上建立了热环境容量数学模型,并结合水质与生态要求获取了三个控制指标。采用模型试算法,确定了该海域目前的热环境容量为1 725 m3“℃/s,在建核电厂投运后排热量为1 500 m3”℃/s,满足相应的热环境容量要求。研究结果可为温排放的统筹管理和海域资源的阶梯开发提供技术支撑。
The connotation of the thermal environment capacity of the receiving water body is expounded, and the thermal emission control method of the coastal power plant based on the thermal environment capacity assessment index and the thermal environment capacity simulation is proposed. Taking Huangmaohai sea area as an example, a mathematical model of thermal environment capacity was established based on tidal current numerical simulation, and three control indexes were obtained according to water quality and ecological requirements. The model test method was used to determine the current thermal environment capacity of the sea area is 1 725 m3 / s and the heat release capacity is 1 500 m3 / s after the project is put into operation, which meets the corresponding thermal environment capacity requirements . The results can provide technical support for co-ordinated management of temperature discharge and ladder development of marine resources.
