英文摘要: Reclaimed water contains large amounts of nutrients (N, P, etc.), which make reclaimed water reuse district face certain pollution risks. Aquatic plants combining compound microorganism preparations can be a practical method to purify in situ reclaimed water. Based on this approach, Typha angustifolia (emergent plant) and Myriophyllum verticillatum (submerged plant), as well as Nitrogen-Cycle Bacteria (compound microorganism preparation) were chosen to test the N, P purification effects in reclaimed water by simulated field experiments. The results showed that: TN removal efficiency in emergent plant configurations was above 60%, and the best configuration was Typha angustifolia (20 strains/barrel) combined with Nitrogen-Cycle Bacteria (8 g/m(3)) (TA+NB_High, TN removal efficiency was 88.2%). The average removal rate of TN in Myriophyllum verticillatum combined with Nitrogen-Cycle Bacteria treatment (MS+NB_Low) was 25%, TP removal rate was about 76%, and BOD5 removal rate was about 45%. In emergent aquatic plants combined with Nitrogen-Cycle Bacteria treatments, the adsorbed and utilised nitrogen by aquatic plants was from flux transfoanation among overlying water, interstitial water and sediment, which reached higher removal effect in 30-90 days, the recommend harvest frequency for emergent plants is one test cycle (30 days).
