Abstract

Abstract: Mean purification ability and remove efficiency of nitrogen（N）and phosphorus（P）were investigated by using six plants with Ipomoea aquatica Forsk, Scindapsus aureus, Pinellia pedatisecta Schott（including earlier stage and later stage）, Philodenron selloum Koch and Epipremnum aureum in the condition of static water. The results as the following:（1）the order of the removal efficiency of N and P was expressed as: I. aquatica Forsk>P. pedatisecta Schott（later stage）>E. aureum>P. selloum Koch>P. pedatisecta Schott（earlier stage）>S. aureus. The remove efficiency of total nitrogen（TN）, total phosphorus（TP）, NO-N, NO-N, NH₄⁺-N and PO₄^3--P was 41.81%, 54.92%, 88.57%, 73.67%, 57.81% and 85.83%, respectively.（2）the order of the recovery rate of dissolved oxygen was expressed as: P. pedatisecta Schott（later stage）>P. pedatisecta Schott（earlier stage）>E. aureum>P. selloum Koch>S. aureus>I. aquatica Forsk. The recovery rate of dissolved oxygen was 40.23%. In conclusion, combined the results of the remove efficiency and recovery rate, E. aureum and P. pedatisecta Schott（earlier stage）could be chosen as the possible plants to purify water.

Key words: plants, purify water, removal efficiency of N and P, recovery rate of DO
