The Degradation Law of Three Nitrogen in the Wetland of ShenYang Xiquan Lake

Article Preview

Abstract:

For the water pollution problem in the wetland of Xiquan Lake in Shenbei of ShenYang, we carried out the degradation and adsorption expriements of three nitrogen and explored the law of them. We collected the soil and indigenous plants at the scene, by measuring the growing season and non-growing season soil and plant removal rate of ammonia nitrogen,nitrate and nitrite nitrogen, analysis the degradation and adsorption law of the wetland soils and plants for the three nitrogen. We take use of the reaction rate equation to calculate the two growth cycle average coefficient of the degradation and adsorption. The results show that the soil and plant can take in some of the three nitrogen. When the adsorption reaches the saturation, they come to dynamic equilibrium.
