英文摘要： In order to solve the problems of hypolimnetic anoxia, endogenous pollution and eutrophication during the stratified period, high load water pollution when the natural mixing occured, and to exert the favorable effects on continuously increasing dissolved oxygen and improving water quality during the natural mixing process, the focused research work of this project are as follows, on the basis of the study of water quality evolution characteristics in stratified reservoirs and artificial mixing-oxygenating technology, (1)Effects of thermal regime on water quality evolution processes and its mechanism, (2) Dynamic process and control conditions for destroying stratification, inhibiting the release of endogenous pollution and controlling algal blooms by artificial mixing-oxygenating technology, (3) Synergistic effect on water quality continuous improvement of artificial mixing and induced natural mixing of stratified reservoirs, (4) Mechanism , technique and dynamic process of water quality evolution after complete of natural mixing induced by the artificial mixing of the reservoir. By making the fullest use of reservoir natural mixing process and the existing engineering platform, the operating conditions of the artificial mixing system which induces natural mixing of reservoir will be optimized, and effects and technical strategy on water quality improvement for stratified reservoir of water source will be proposed in order to provide theoretical guidance and technical support for inhibiting the release of endogenous pollution , controlling algal blooms, continuously improving water quality and reducing power consumption.
