Key Nutriments Persistence with Various Loading of Phosphorus Pollution in Cihu Lake, China

Abstract:

Dredging is the available method to clarify eutrophic lake water for some engineers in recent years. This engineering may cause at least two negative influences on water environment, (a) pollution by dredging would occur during the operation, and (b) long-term effect degrade with some lake become dirty subsequently. Changes of the concentration of TP after the engineering of dredging are the focus in this paper. The content of total carbon (TC) and total nitrogen (TN) change at the same time for different original concentration of TP. Five grade original concentration of TP was simulated and the changing law was presented with the process of duration (D) and the change of temperature (T) as the independent variables. The results indicated that the concentration of TP decreased almost to 50% of their original ones respectively. But the changes of concentrations of TN and TC abide by the distinguished rule.
