The Water Quality Prediction And Water Pollution Control Research For Mid-Lower Reach Of Hanjiang River Of Middle-Route Of South-to-North Water Transfer Project

Middle-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 resource shortage in Beijing and Tianjing and the area of North of China, and improving the ecological environment of diverting area, and promoting the economy and society of diverting area to develop continuously and steadily. However, physical geography distribution of the water resource between basins will be changed, the hydrology situation of diverting area and water origin area will be transformed because of water transfer, thereby the water quality and ecological environment of diverted area will be impacted deeply. In this paper, in light of regulation principle of Middle-Route of South-to-North Water Transfer Project, aimed for all regulation projects, especial for short term project, theory and technology of system simulation and oriented object modeling methods are applied to establish simulation model, to develop the simulation platform soft of water quality prediction and water pollution control regulation of mid-lower reaches of Hanjiang river in Middle-Route of South-to-North Water Transfer Project; The research of this simulation system can be provided as a proof for demonstrating and determining the regulation projects as well as environment management. It is significant for the water resource distribution and the development of ecological environment construction. As a subsystem of South-to-North Water Transfer Project system simulation, it is compatible with the other subsystem, and can be run lonely, this platform soft has the good interface, can be manipulated conveniently, can be used widely,. It comes up to the development of computer technology and has the character of enlarging easily.In this paper, this platform is provided for simulating the impact of water transfer on water quality of mid-lower reaches of Hanjiang river and water quality of mid-lower reaches of Hanjiang river in different hydrology conditions, simultaneously, a series of simulation experiments are carried on, and come into the dependable and stable simulation results that in some extent the water quality of mid-lower reaches of Hanjiang river is not affected because of water transfer; and after water transferred, the water quality is good in most of reaches of mid-lower reaches of Hanjiang river, in some of that the water quality is go against the requirement for the water quality, the measure of water pollution control planning in the mid-lower reaches of Hanjiang river is made out.
