Abstract
In order to calculate and analyze the ship sewage river water environment, the influence of internal selection of rivers into the lake taihu main Chengdong port as the research object, based on the speed of flow, ship, ship engine power data such as a ship sewage and oil wastewater is put forward and the calculation method of and on the basis of zero dimensional water quality model, using the method of simulation optimization control goal against the push model (COIM method), the water environmental carrying capacity and the associated model of ship emissions of pollutants. The maximum bearing capacity of the Chendong port water body to the ship is deduced by using the correlation model, and the method to improve the bearing capacity of the water body is proposed according to the COIM model. The results show that the number of ships can be accommodated in Chendong Port is more than three times that of the existing ships, and the organic oxygen consumption (COD), nitrogen (N) and phosphorus (P) in the ship sewage have no significant influence on the water environment of Chendong Port.
