| Abstract: | Substrate types and season changes were employed to study the effects on nitrogen removal efficiency of the constructed wetlands. The following conclusions are concerned by the study. Nitrogen removal efficiency can be affected by substrate types, compared with the combined substrate, cinder substrate is more fit for the removal of nitrogen. Season changes has a significant impact to nitrogen removal efficiency, the sequence of average nitrogen removal efficiency is summer 〉 autumn〉 spring 〉 winter. |
