Limit Level for Pollution Control of Sluices and Dams on Shaying River

Because of the serious pollution of Shaying River, the excessive water storage by sluices and dams on that river is one of the prime reasons for the pollution of trunk stream Huai River. To counter this problem, this paper tries to regulate the water storage by sluices and dams on Shaying River, this paper explores the limit level for pollution control to prevent water pollution incident caused by centralized discharge of polluted water by proposing and defining the concept of limit level for pollution control, and establishing a model of limit level for pollution control of sluices and dams for the purpose of reservoir profiting and pollution-control. Besides, this paper applies the above method to multiple sluices and dams on Shaying River in Huai River Basin, and solves the model by multi-objective genetic algorithm. The calculation results indicate that the established model is a practical, effective way to determine the limit level for pollution control of sluices and dams on Shaying River which provides important technical support for the development of pollution-control regulation among sluices and dams in Huai River Basin in China.
