Abstract:: Four kinds of wetland plants, including Iris pseudacorus, Typha orientalis, Zizania aquatica and Phragmites australis were selected to study the removal efficiency of total nitrogen (TN), total phosphorus (TP), ammonia nitrogen (NH₄⁺-N), biological oxygen consumption (BOD₅) and chemical oxygen consumption (COD_Cr) from domestic sewage by plants and the N, P accumulation in biomass in the constructed wetland. The results showed that: (1) the purification efficiencies of four kinds of wetland plants were different in a ‘V’ type with the seasons which showed rebound period > stabilization period > recovery period > period start; (2) the four kind of plants in constructed wetland could effectively promote the removal efficiency, which showed that Iris pseudacorus and Zizania aquatica were higher than Typha orientalis and Phragmites australis, while the removal efficiencies of TP, NH₄⁺-N and COD_Cr had no significant difference (p > 0.05); (3) the aboveground and the underground biomass showed Iris pseudacorus and Zizania aquatica were higher than Typha orientalis and Phragmites australis, and the ratios of most plants biomass aboveground (A/U) varied between 1 and 2 except for Iris pseudacorus, the underground biomass accounted for more than 40% to total biomass, and the concentrations of nitrogen and phosphorus of aboveground biomass were higher than those in the underground biomass, which showed that Iris pseudacorus and Zizania aquatica were higher than Typha orientalis and Phragmites australis; (4) correlation analysis showed that plant accumulations of nitrogen and phosphorus displayed significantly positive linear correlation with plant biomass and concentrations of nitrogen and phosphorus (p < 0.01), and biomass could be used as an indicator to screen the appropriate artificial wetland plants.
