| Abstract: | Although the mechanism of lake eutrophication is complicated,the basic factors are improper artificial activities and uncontrollable management.The pollution sources were classified as primary and secondary.Strictly managing and controlling the sources of primary and secondary pollution sources were favorable for lake eutrophication control and improvement of water quality.According to theory and practice of our comprehensive control,this paper provided ample evidence of primary pollution source control in many ways.For pointsource,by intercepting and dredging, for area-source,by channel engineering,management engineering and bioengineering which played function in collectiontransformation of aquntic plants and aquatic animals, and also in protection of biological zones.It was clarified that the mechanism and effect of controlling entrances of nutritive substances. In addition, the evaluation of secondary sources had also been done on safety, stability, expenditure and efficiency,based on starting practice,intermediate practice and enlarged practice, in removing mechanism and biopurification of soluble N and P by culturing aquatic plants at the edge of lake, by precipitation,absorption, flocculation and complex of power coal ash,etc.,by exchange of high concentrative N and P in bottom layer,and by blockade and stabilization of precipitated N and P in bottom mud. |
