Abstract
The numerical simulation of tidal current field in wide and shallow waters (Naochao River) of Caofeidian industrial zone is carried out by using a two-dimensional hydrodynamic model, taking the discharge problem of temperature and drainage in a refinery integration project as an example. Taking the tidal current field as the hydrodynamic condition of the temperature drainage transport simulation, the concentration distribution of the temperature drainage in the receiving water area was predicted by using the two-dimensional convection-diffusion model of the temperature drainage, and the change of the temperature rise line and its influence were analyzed. The results showed that the water area affected by temperature rise in winter and summer were 0.28km2 and 0.35km2, respectively, when the project was discharged separately. The existing temperature displacement of China Resources Power Plant in the superposition area is: 19.1km2 in winter and 1.64km2 in summer under the influence of temperature rise. By analyzing the influence degree of wide and shallow water (Naochao River) drainage outlet on temperature rise, the conclusion that the layout of drainage outlet should be further optimized is given. conclusion that the layout of drainage outlet should be further optimized is given.
Highlights
In recent years, with the construction of coastal nuclear power plants and thermal power plants, a large number of thermal drainage into the coastal waters, so that the problem of Marine thermal pollution gradually prominent

Summary
With the construction of coastal nuclear power plants and thermal power plants, a large number of thermal drainage into the coastal waters, so that the problem of Marine thermal pollution gradually prominent. Since the temperature drainage will cause the water intake to heat up synchronously, the location of the discharge outlet will greatly affect the unit efficiency [1,2,3].From the beginning of 1980s, many domestic scholars began to conduct the simulation research of temperature drainage. Li Yanchu [4] used ADI difference method to conduct numerical simulation on the influence of temperature drainage of Punyu Power plant on the nearby sea area. Hua Zulin et al [5] conducted numerical and physical model studies on the temperature drainage of two large power plants in the Yangtze River Estuary, and predicted the influence range of temperature drainage and temperature rise distribution. Yan Bing et al [7] adopted unstructured grids to compare the influences of different extraction and drainage outlet
