Performance of Horizontal Subsurface Flow Constructed Wetland of Application of Oily Wastewater

Abstract:

In order to evaluate the effects of constructed wetland treating oily wastewater, wastewater treatment was monitored during five months. The results showed that when the influent flux was 1.2m3/d, the mean removal rates of COD, TN, NH4+-N and mineral oil in the horizontal flow constructed wetland were 54.27%, 53.47%,54.84% and 50.19%, respectively. Constructed wetland had better removal efficiency and run stably in the treatment process of oily wastewater.
