The goal of this study was to compare the effects of three plants (ryegrass, chicory and cress) in floating bed systems on purification of sedimentation pond wastewater (low-concentration) and biogas slurry (high-concentration) from geese farm in winter. The results showed that the floating bed with ryegrass had better removal rates on chemical oxygen demand (COD), total nitrogen (TN) and total phosphorus (TP) of low-concentration wastewater than other groups at 60 days (P<0.05), and the removal rates were 53.0%, 83.3% and 61.1% respectively. At 90 days, cress has the best performance on removing 5- day biochemical oxygen demand (BOD5) and turbidity (P<0.05), with a removal rate of 82.9% and 80.8%. The removal rates of BOD₅, COD, TN and turbidity by ryegrass in highconcentration wastewater were significantly higher than other treatments (P<0.05), which were 84.0%, 70.2%, 56.2% and 82.1% respectively. However, ryegrass had better stem height, root length and plant biomass production compared with cress and chicory. In conclusion, ryegrass was an optimal floating plant for purification of geese wastewater in winter and the optimal treatment time was 60 days. The regress has strong adaption for fluctuate concentrations of pollutants and is suitable for treatment of livestock and poultry wastewater in practice.
