碩士 === 國立中山大學 === 海洋環境學系 === 84 === Using Ocean Outfall equipment to dilute and clean the wastewater has become a popular method to solve the problem of waste water for coastal cities in many countries. It solved the pollution problem by huge capacity of dilution in the Ocean and lower con- centration of pollutants. Because the Ocean have infinite capac- ity of dilution and the cost were cheaper in operation for a long time, it has the developmental potentiality in treating wa- stewater in the future. But inproperty operation and weak design will cause the secondary pollution in coastal zone , so there are many engineers still devote themselves to this study today. This paper extends Chen and Yuan's(1996) three dimensional numerical model, to establish three dimensional finite differe- nce turbulent diffusion model which solves Reynolds Average Navier-Stoke eqution and Diffusion eqution for simulating the change of flow field and pollutants in process of discharge.
