中文摘要：
使用打有孔洞的泡沫板作为栽培定植板，研究了菖蒲对3种不同浓度污水中氮、磷的净化效应。结果表明：试验进行30d后，菖蒲对低、中、高浓度污水的总氮（TN）去除率分别为60．3％、67．9oA、73．9％，对低、中、高浓度污水的铵态氮（NH4^＋-N）去除率分别为65．1％、68．2％、75．6％，对低、中、高浓度污水的总磷（TP）去除率分别为52．8％、60．0％、62．6％。菖蒲对高浓度污水中总氮、铵态氮和总磷的去除率最高，可用于污染水体的生物／生态修复。
英文摘要：
Using foam board with poles as planting plate, the effects of Acorus calamus on nitrogen and phosphorus purification were studied in sewages of three different concentrations. The results showed that after 30 days ~ experiment, Acorus calamus ＇ s removal rates of TN in low, middle, high concentration sewages were 60. 3%, 67. 9%, 73. 9%, respectively. Acoruscalamus＇s removal rates of NH4 ^＋ -N in low, middle, high concentration sewages were 65. 1%, 68. 2%,75. 6%,respective!y. Acorus calamus＇s removal rates of TP in low, middle, high concentration sewages were 52. 8% ,60. 0%,62. 6%. Acorus calamus showed the best removal rate of TN, NH4 ^＋ -N,and TP for high concentration sewage,which could be used for biological/ecological rehabilitation of polluted water bodies.
