摘　　要： 介绍了2种用于猪场污水氧化塘中进行污水净化处理的漂浮栽培植物修复系统的技术原理、特点、系统组成、种植管理技术,研究了在这个系统中种植美人蕉Cannageneralis、风车草Cyperusalternifolius、香根草Vetiveriazizanioides、蕹菜Ipomoeaaquatica、细叶萼距花Cuphenhyssopifolia、彩叶草Coleusscutellarioides、金叶木Sanchezianobilis和紫杯苋Cyathulaprostrata等几种植物的生长状况以及这些植物对污水中氮、磷的净化效果.结果表明,这2种漂浮植物修复系统具有设施简单、管理方便的特点.这些植物中的美人蕉、香根草、蕹菜、细叶萼距花等在该系统中生长良好并具有很好的水质净化效果和广泛的应用前景. The technical principles, characteristics, composition and planting techniques of 2 kinds of floating phytoremediation systems made with bamboo and degradable polyfoam plate were described. The growth of Canna generalis, Cyperus alternifolius, Vetiveria zizanioides, Ipomoea aquatica, Cuphen hyssopifolia, Coleus scutellarioides, Sanchezia nobilis, Cyathula prostrata and the purification effects on N and P in piggery wastewater by these plants cultivated in the systems were also investigated. The results showed that the floating phytoremediation system was simple to install and manage, and durable too. Canna generalis, Vetiveria zizanioides, Ipomoea aquatica and Cuphen hyssopifolia had good purification effects on N and P in piggery wastewater. These systems have prospects for a vast range of application in purifying wastewater.
