Study On The Ecological Restoration Technology Of Beidagang Reservoir

The "Yellow River economy",tianjin project storage reservoir in tianjin-Beidagang reservoir,for the eastern route project.In recent years,the water resources in the reservoir has changed dramatically,which has been shown as follows: the amount of water is reduced greatly,the water quality of the reservoir is bad,and the function of the city water source is greatly weakened.In order to make the water environment management and water ecological restoration technology research,the research on the water environment management and water ecological restoration technology of Beijing University,and promote the development of Tianjin City,it has important significance for the development of the city.In this paper,the following aspects of in-depth study:(1)Summarizing the existing research results on the ecological restoration techniques of reservoir slope protection,the eutrophication evaluation and control methods,the conclusions and shortcomings of the existing research and the main research contents of this paper are summarized.(2)This paper introduces the present situation of the ecological situation of the Beidagang reservoir,especially the water quality of the reservoir,and puts forward the corresponding improvement measures.(3)According to the actual situation of Beidagang Reservoir screening of aquatic plants,the assembly experiment of submerged plant restoration and submerged aquatic plants and water plants,ensure the smooth implementation of aquatic macrophyte restoration demonstration project.(4)Research on the practicability of environmental protection green vegetation concrete technology.(5)Through the demonstration project,the water plant restoration and water quality improvement are achieved successfully,and the results show that the water plant and the reservoir water quality improvement.Through the research of this paper,the improvement measures of the ecological environment of the reservoir in Beijing University are put forward:After drinking water,because of the poor quality of water pollution and the release of sediment pollutants,it is necessary to restore the diversity of aquatic plants as a basis,supplemented by strengthening reservoir management,thereby reducing water pollution and ensuring the safety of drinking water.Submerged plant purification plays a key role in the process of water in the Beidagang Reservoir,to ensure the diversity of aquatic plants,will also greatly enhance the ability of water purification.Aquatic plants and submerged plants combination can improve the self-purification capacity of water bodies,especially the increase of organic matter degradation ability.Through the restoration of aquatic plants,floating plants and submerged plants could significantly reduce the content of organic matter in water,rich in algal diversity,has a positive effect on improving water quality and ecological stability.Environmental protection type of green vegetation concrete has the function of protecting the dam and the green,which is beneficial to prevent soil erosion,and increase the function of ecological and water conservation and water conservation.The proposed Beidagang reservoir water environment management and water ecological restoration technology scheme,and puts forward the environmental protection green vegetation concrete technology is adopted to Beidagang reservoir in ecological slope protection.For many in our country the reservoir water ecological environment governance of science and technology level of ascension is of great significance.Research results of the project,can be used in other reservoir water environment ecological management,solve the bottle diameter effect of reservoir water environment deterioration,popularization and application prospect.
