Modelling Phosphorus Removal in Horizontal Subsurface Flow Constructed Wetlands

Longhua Gao and Long Xie
Abstract—In this paper a mathematical model for prediction of phosphorus removal with total phosphorus (TP) as the check index in horizontal subsurface flow constructed wetlands was developed. The model considered the water flow and transportation, diffusion, dispersion and biochemical reaction of phosphorus. The physical and biochemical parameters of the model were calibrated by one set of the experimental data. Then the model was valided by another set of the experimental data. The predicted effluent TP concentrations were well agreed with the actual effluent TP concentrations. The model can be used to simulate the phosphorus removal effect in horizontal subsurface flow constructed wetlands. The average removal rate of TP for domestic sewage in planted and unplanted constructed wetland with high concentration of influent were 88.22% and 85.06% respectively, while their removal rates were 94.23% and 90.77% respectively with low concentration of influent. So vegetation had improvement effect on TP removal.

Index Terms—Horizontal subsurface flow constructed wetlands, mathematical model, numerical method, phosphorus removal.
