选择慈姑、水葱、香蒲、小叶章、菖蒲、泽泻、芦苇、地榆、水莎草9种典型湿地植物,构建小型人工模拟湿地,分析在不同水力停留时间下湿地植物对城市生活污水的净化能力。研究结果表明,最佳的水力停留时间为5 d,植物对COD、TN和TP的平均去除率分别为：55.25%、81.80%、77.51%,均高于对照组;植物对COD的去除能力大小排序为：香蒲〉菖蒲〉水莎草〉水葱〉慈姑〉小叶章〉泽泻〉地榆〉芦苇;对TN去除能力大小为：香蒲〉慈姑〉菖蒲〉小叶章〉水莎草〉水葱〉泽泻〉地榆〉芦苇;对TP去除能力的大小依次为：香蒲〉小叶章〉慈姑〉水葱〉菖蒲〉水莎草〉泽泻〉地榆〉芦苇。综合分析表明,香蒲、菖蒲、水葱和慈姑的净污能力最强,可应用于人工湿地中。
選擇慈姑、水蔥、香蒲、小葉章、菖蒲、澤瀉、蘆葦、地榆、水莎草9種典型濕地植物,構建小型人工模擬濕地,分析在不同水力停留時間下濕地植物對城市生活汙水的淨化能力。研究結果錶明,最佳的水力停留時間為5 d,植物對COD、TN和TP的平均去除率分彆為：55.25%、81.80%、77.51%,均高于對照組;植物對COD的去除能力大小排序為：香蒲〉菖蒲〉水莎草〉水蔥〉慈姑〉小葉章〉澤瀉〉地榆〉蘆葦;對TN去除能力大小為：香蒲〉慈姑〉菖蒲〉小葉章〉水莎草〉水蔥〉澤瀉〉地榆〉蘆葦;對TP去除能力的大小依次為：香蒲〉小葉章〉慈姑〉水蔥〉菖蒲〉水莎草〉澤瀉〉地榆〉蘆葦。綜閤分析錶明,香蒲、菖蒲、水蔥和慈姑的淨汙能力最彊,可應用于人工濕地中。

A total of nine wetland plants including Sagittaria trifolia Linn,Scirpus validus Vahl,Typha orientalis Presl,Deyeuxia angustifolia Y.L.Chang,Acorus calamus Linn,Alisma plantagoaquatica Linn,Phragmites australis,Sanguisorba officinalis Linn and Juncellus serotinus were selected to construct a small-scale man-made wetland in Harbin.The pollutant removal ability of these wetland plants were analyzed under different hydraulic retention time.Results showed that the optimal hydraulic retention time was 5d,and the average removal rate of TN,TP,COD among the wetland plants was 81.80%,77.51%,and 55.25%,higher than that of the control groups.The removal capacity of TP were ordered as follows:Typha orientalisDeyeuxia angustifoliaSagittaria trifoliaScirpus validusAcorus calamusJuncellus serotinusAlisma plantagoaquaticaSanguisorba officinalisPhragmites australis.The order of the removal capacity of TN was:Typha orientalisSagittaria trifoliaAcorus calamusDeyeuxia angustifoliaJuncellus serotinusScirpus validusAlisma plantagoaquaticSanguisorba officinalisPhragmites australis.The order of the removal capacity of COD was:Typha orientalisAcorus calamusJuncellus serotinusScirpus validuSagittaria trifoliaDeyeuxia angustifoliaAlisma plantagoaquaticaSanguisorba officinalisPhragmites australis.These results indicated that Typha orientalis、Scirpus validus、Sagittaria trifolia were the best wetland plants with higher removal ability,which could be used in constructed wetlands.
