摘　　要：考察艾蒿人工生态绿地在不同水力负荷下对生活污水中氮和磷的去除效果。结果表明,艾蒿人工生态绿地启动快,处理效果稳定。人工生态绿地构建后即有很好的除磷效果,构建2周后有较好的除氮效果,在试验的水力条件下,总氮去除率达92%-95%,水力负荷对总氮去除率的影响小,总磷的去除率可达到95%,水力负荷对总磷去除率的影响很大。The study was conducted to evaluate the artificial ecological greenbelt of Moxa (Artemisia argyi Levl et Vent) performance in removing nitrogen and phosphate from domestic wastewater under various hydraulic loading rates. The artificial ecological greenbelt (AEG) showed rapid start-up behaviors in which process stabilities were achieved in the following sequence: phosphate removal in the AEG of Moxa without an adaptation period, nitrogen removal in the AEG of Moxa after 2 weeks, Nitrogen removals were excellent, with efficiencies of 91% to 92%. Removal efficiencies were affected little by the hydraulic loading trials. Phosphate removal of 95% can occur, with the efficiencies being inversely related to hydraulic loading.
