Abstract

In this study, aquatic plants were used to control the pollution of eutrophicated water. The results showed that aquatic plants had a higher ability to remove total nitrogen (TN), total phosphorus (TP) and nitrate nitrogen. Among them, foxtail alga (Myriophyllum verticillatum) and grain leaf pondweed (Potamogeton maackianus) could effectively remove TN (83.84% and 77.54%), TP (91.3%) and nitrate nitrogen (95.85% and 90.65%), but had no significant effect on removing ammonia nitrogen (only 14% to 70%). Sediment shielded by plastic could prolong the release of the nutrients from it for 15 to 20 days, and show the compensation effect later. The results also showed that aquatic plants could greatly improve the transparency of water, but could not improve the COD and DO of water effectively.
