Nitrogen and phosphorus removal performance and kinetics absorption by Ipomoea aquatica
摘要
Abstract
The absorption kinetics of ammonium, nitrate and phosphorus by Ipomoea aquatica were studied,after that ammonium, nitrate and inorganic phosphorus removal from eutrophic water was examined under indoor static simulation experimental condition. The relationship between the uptake rate and the concentration was depicted using the Michaelis-Menten equation. The purposes of this study were to provide a scientific foundation for the removal mechanism of ammonium ,nitrate and inorganic phosphorus from water. The results showed that the maximum velocities (Vmax) of absorption on ammonium, nitrate and inorganic phosphorus were 23.59, 2.88 and 1.52μmol/( g FW·h), the Michaelis constant(Km ) were 1.90,10. 94 and 0. 97μmol/L. The results of static state removals of TN, NH4+-N, TP, DOP by I aquatica were 38.13％ ,44. 85％ ,63.77％ and 53.95％ , respectively. It is proved that I. aquatica could be used to purify the eutrophicated water body.关键词
