| Abstract: | Constructed wetland and its removal mechanisms of nitrogen and phosphorus in wastewater treatment were introduced. Latest research status of removal efficiency improvement of nitrogen and phosphorus were systematically expatiated on process optimization, wetland plants, substrates and microorganisms. Some proposals about the ways to improve the removal efficiency of nitrogen and phosphorus were given, such as optimizing the design of constructed wetland system, screening of wetland plants species, combination of substrate, and microorganism population adjustment in the bed of constructed wetland. Based on which the current problem and research orientation of constructed wetland were discussed. |
