摘要:In this paper, a new porous subsurface flow constructed wetland was developed to remove BOD, TN and TP from sewage. A water inlet is arranged at the front of the wetland 0.25m and 0.45m from the ground. The design has the characteristics of simple structure and uniform water distribution, which makes the wetland easy to construct and improve the removal effect of pollutants. The results showed that the average removal rates of BOD, TN and TP in the wetland system were 85.63%, 80.29% and 89.07%, respectively, when the average temperature was 26°C and the hydraulic retention time was 1.3d. The removal effect is good, which can play a certain ecological and social benefits.
