Purification of Nitrogen and Phosphorus in Lightly Polluted Landscape River by Effective Microorganisms Combined with Submerged Plants

In this paper the purification performance of nitrogen and phosphorus in slightly polluted water by the combination of EM and submerged plants, Hydrilla verticillata was investigated. The results showed that the combination of EM and Hydrilla verticillata have a good purification effect on TN and TP in lightly polluted water, and the removal rate could reach to 70% and 97.3%, respectively. As compared with the treatments of aquatic plants and EM separately, the removal rate of TN and TP were increased by 23.4%, 2.1% and 23.4%, 41.3%, respectively.
