The Interception and Decontamination of Nitrogen in Input Watercourse by Lake Wetland

Abstract:

This paper select Ezhen Lake and Caohuhu Lake, which are located in the waterway of Wangyu River, as research objects in order to research the interception and decontamination of total nitrogen, dissolved total nitrogen, particle nitrogen, ammonia, nitrate and nitrite in the lakes and their impact factors. The main results are as follows: The two lake wetlands could remove nitrogen from input watercourse by interception and decontamination, especially particle nitrogen and nitrate. Factors like space shape of lake and the area, hydraulic retention time and the distribution of hydrophyte in wetlands affected the removal rates of nitrogen. This study provides theoretical and technical support for the operation and management of the project of “water diversion from Yangtze to Taihu”.
