Study On Water Quality Simulation Of The Regional Aquatic Enviroment Of East-Route Of South-to-North Water Transfer Project And The Pump Running Plan

East-Route of South-to-North Water Transfer Project is the important part of South-to-North Water Transfer Project, it is important for solving the water resources shortage along the line of South-to-North Water Transfer Project ,and improving the economy and society of diverting area to develop continuously and steadily. However, the quality of transferring water bears directly on the service value of water resources and improvement of the society along the line. And it not only determines the actual profits of water transfer project but also brings important influence to aquatic environment along the line of water transfer.Located in the southwest of the city of Huai'an of Jiangsu province ,Huaiyin No.2 pumping station is the constituent parts of the third pumped junction of East-Route of South-to-North Water Transfer Project in china. Because of Huaiyin No.2 pumping station adjacent to the city of Huai'an where water was polluted seriously, the water source of the pump was polluted in some degree. Once the pump was running, with a lot of polluted water coming in, it would cause upper deteriorated water quality and influence the water quality of East-Route of South-to-North Water Transfer Project. It's urgent to study on water quality prediction of the regional aquatic environment and the Pump Running Plan of Huaiyin No.2 pumping station. This paper discussed these contents:1 study on the water transfer instances at home and abroad and the history,present status and trend of water quality model of rivers.2 based on Huaiyin No.2 pumping station, with the survey of pollution sources and the result of water quality monitoring of some rivers, analyze the major water quality problem and pollutant of regional aquatic environment.
