摘    要:研究了两栖榕在潜流型人工湿地的生长特性及其对污水的净化效果。一年多的实验表明,生长在人工湿地的两栖榕具有发达的侧根和不定根,保持正常的净光合速率,蒸腾速率,根系活力生长速率。两栖榕人工湿地对TN,TP,CODCr和BOD5的去除率分别为54.2%、40.9%、72.4%和74.3%,与无植物系统相比较,去除率分别提高了17%、12%、10%和11%,此外,两栖榕人工湿地系统中,水力停留时间对去除率果有一定影响。

关 键 词:两栖榕  人工湿地  去除率  水力停留时间  净光合速率  污水净化效果

Abstract:The amphibious banyan (Ficus spp.), an evergreen tree mainly in Guangdo ng Province, is conspicuously distinct from a commonly cultivated and widely dis tributed banyan in subtropical China, Ficus microcarpa, in morphology, anatomy a nd flooding tolerance. In the study presented in this report, two main approache s were made to: (1) the morphological, growth-related and photosynthetic charac t eristics, and (2) the purifying efficiency for sewage of amphibious banyan culti vated in the constructed wetland. ...
Keywords:amphibious banyan  constructed wetland  removal rate  hydraulic rete ntion time (HRT)  net photosynthetic rate
