Jin-hae bay in enclosed sea area has been more serious water quality due to the eutrophication and red tides etc., since 1989.
In order to deal with it, Government has spent totally 28.5billion from 1990 to 1994 and are doing the dredging work for removing contaminent in the bottom of the sea. Also government are operating sewage disposal plant but water quality is still bad.
Especially, the water quality in the ok-gye sea area is bad and the result comes from the environmental load of Masan-Changwon seawage disposal plant.
In this study, we carry out the sea water flowing simulation and understand the flowing characteristics of the objective sea area. By using that calculated flowing data, we construct the simulation model of pollution diffusion and then through that simulation we aime at gasping the characteristics of that water quality environment.
In case discharge of Masan-Changwon sewage disposal plant after the first existing treatment flow in the sea area, we calculate the distribution of COD.
In case the developed discharge after the second extension work flow in the sea area, we compare the distribution of COD to that and than we analyzed quantitatively the influence that the pollution load of Masan-Changwon sewage disposal plant are involved in the environment of sea quality in Jin-hae Bay.
