摘要：

阐述了漂浮栽培植物修复系统的技术原理、特点与系统组成， 研究了在该系统中种植美人 蕉和旱伞草2 种植物的生长状况以及这些植物对城市河湖水体中氮、磷等的净化效果。尝试了将 漂浮栽培植物与生物接触氧化技术结合起来， 并研究了植物与生物填料的组合系统对水质的改 善效果。结果表明， 美人蕉和风车草在漂浮植物修复系统对氨氮的去除率均在90%以上， 漂浮栽 培植物与软性填料的组合系统对水中CODMn 的去除率达46%以上。

关键词: 城市河湖, 净化, 漂浮植物修复系统, 生物接触氧化

Abstract:

The technological principle, characteristics and composition of floating phytore mediation systems for water quality restoration were described and analyzed. The growth and effect of Canna generalis and Cyperus alternifolius on TN and TP removal from urban water bodies were also investigated based on experiments. And a new bio - plant technology for water quality restoration of urban water bodies, which combined floating cultivation system with biological contact oxidation, was utilized to purify polluted water of an urban river and a lake in Xi'an City of China. The experimental results showed that Canna generalis and Cyperus alternifolius had better effects on water body purification, and more than 90% of nitrogen was removed by the both systems. And the bio- plant system composed of floating cultivation and soft bio- media could not only remove TN and TP effectively, but also greatly degrade organic pollutants from the water bodies, with a high removal rate of 46% of CODMn obtained.

Key words: biological contact oxidation, floating phytoremediation system, purification, urban lakes and rivers
