摘　　要：选用鸢尾(Iris tectorum)、石龙芮(Ranunculus sceleratus L.)、酸模(Rumex acetosa L.)3种挺水植物作为湿地植物进行无土栽培,研究它们在生活污水中的生长特性及对生活污水中主要污染物的净化能力。试验集中在春末夏初进行,结果表明,3种植物均生长良好。当污水停留时间(HRT)为7 d时,鸢尾对COD,TP,TN去除的贡献率分别为46.74%,17.71%,11.33%;石龙芮对COD,TP,TN去除的贡献率分别为39.82%,28.59%,8.88%;酸模对COD,TP,TN去除的贡献率分别为54.69%,20.26%,7.47%。经过处理后的污水水质显著提高,充分表明这3种植物应用于人工湿地是可行的。Select three macrophytes Iris tectorum, Ranunculus sceleratus L. and Rurnex acetosa L. cultivating with no soil to study their growth characteristics and their ability to removal main pollutants from domestic wastewater. The experiments went on during late spring to early summer, the results show that the test plants grow well. When the retention time is 7 d, the contribution rates of Iris tectorum on the removal of COD, TP, TN are 46. 74%, 17. 71%, 11.33%; while Ranunculus sceleratus are 39. 82%, 28. 59%, 8.88%; Rumex acetosa are 54.69 %, 20. 26 %, 7.470%. After the treatment the quality of wastewater is improved prominently, which indicates that these three rnacrophytes applied to constructed wetland are feasible.
