Water Quality Improvement Technology Research Of Xiaosha River

In order to achieve the water quality requirements of South-to-north water transfer project, according to NanSiHu water quality problems, this research analyzed Ecological restoration techniques used in Xiaosha river. This paper analyzed the changes of the river’s COD, ammonia nitrogen,TN,TP in the repair process. So as to determined the Ecological restoration technology application on river water quality improve effectively.Before the construction of ecological restoration project, the river’s COD, ammonia nitrogen,TN,TP could not reach the standard. The COD were43.38mg/L in this river. But after the construction of Ecological restoration project, the COD were28.68mg/L and the quality is stable. The other three kinds of pollutant also gradually reduced.This paper also analyzed the application of Rubber dam in XiaoSha river. Rubber dam can effectively reduce the pollutants such as COD, ammonia nitrogen,TN,TP in river. The removement of COD is effective, but the other three influenced by climate obviously. Practical application of Rubber dam must cooperate with other repair technology to achieve more rapid and stable repair effects.The construction of Ecological restoration project can restore river ecological system, enhance the role of physics, chemistry, organisms. Improved the river self-purification.
