Research on the Application of Aeration Oxygenation Technology in Urban Black and Odorous Water Quality Improvement

In the fast urbanization,much polluted water was produced,which exceeded the river capacity,leading to the worsen of ecological environment of the urban river,pollution and eutrophication of urban landscape waters in our country were getting increasingly serious in recent years,and the polluted river has been an obstacle for the developing city.The current status and the reasons of urban black and odorous rivers were reviewed,and the application progress of environment improvement technology was introduced,the main questions and solutions of the urban landscape river improvement technology were also analyzed.Hereinto,solar aeration treatment technology could realize the treating both principal and secondary aspect,comprehensive improvement and long-term maintenance of landscape waters,and had remarkable comprehensive advantages and bright practice prospect.
