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.
