[Objective] To investigate the water purification capabilities of Polygonum species and assess their suitability for the remediation of domestic sewage. [Methods] Polygonum hydropiper, Polygonum orientale, Polygonum divaricatum and Polygonum lapathifolium were selected as the research objects. The removal effects of total nitrogen (TN), ammonium nitrogen (NH4+-N), nitrate nitrogen (NO3--N), and total phosphorus (TP) in two concentrations of domestic sewage by these four species of Polygonum were discussed through a simulated hydroponic experiment. Additionally, the accumulation ability of Polygonum species to nitrogen and phosphorus in sewage was examined. [Results] (1) All four species of Polygonum exhibited good removal effects on nitrogen and phosphorus in two concentrations of domestic sewage. (2) Under high concentration sewage treatment, the removal rates of TN, NH4+-N and TP by Polygonum orientale, Polygonum divaricatum and Polygonum lapathifolium were 96.04%~97.41%, 94.60%~97.79% and 98.78%~99.68% (28 days), respectively, which were significantly higher than those of Polygonum hydropiper (p |
