jaue2016105: Study on the Effect of Subsurface Flow Constructed Wetland on Nitrogen and Phosphorus Removal

Abstract

Subsurface flow constructed wetland for removal of organic matter and nitrogen and phosphorus are affected by a variety of factors，This article Study on different hydraulic loading and discharge height on pollutant removal effect. Results show that：discharge height will not significantly affect wetland TP、COD concentration，the removal of NH4-N is slightly under the influence of drainage height，and as the hydraulic load increase and decrease. Denitrification under the influence of height of drainage, water height, and denitrification enhanced.
