Abstract:In order to study the general effect of treatment of sewage using a horizontal subsurface-flow constructed wetland, a more detailed wetland regression equation of TN、TP needs to be established to guide the design of constructed wetlands. In this study, we used the main pollutant index TN、TP as indicator and classified more than 500 groups of collected data in accordance with the season, hydraulic loading, planting vegetation type in accordance with the "black box model". We analysed different factors affecting pollutant removal by constructed wetlands, took use of season and the hydraulic loading as the main classification criteria. Based on that ,12 groups of regression equations for TN and TP removal were established according to the linear regression method. The goodness of fit R2 values ranges from 0.65 to 0.95, showing the accuracy has been greatly improved.
