With retention time prolonged, the concentrations of TN, NH4(superscript +)-N and TP of domestic sewage were obviously reduced in all floating-bed systems, however the NO4(superscript +)-N concentrations were gradualjy accumulated due to the stronger nitrification than denitrification. The plants in floating-bed system increased significantly the N2O flux, which was 174.44μg/(m^2h), 82.19μg/(m^2h), 112. 49μg/(m^2h) and 44.81μg/(m^2h), respectively, for the Lolium mutliflorum, Oenanthe javanica, Vetiveria Zizanioides arid none-plant floating-bed systems.
