%X Phosphorus removal in subsurface constructed wetland treating agriculture non pointed wastewater was studied in pilot scale. The experimental results showed that the removal rates of TP increased with HRT increasing when the nominal hydraulic retention time was less than 5 days. The pH decreased distinctly when the retention time was too longer in the batch and sequence style, it may bring on a lower removel rate of TP. The amount of TP that can be removed by harvesting were about 15.8% and 9.5% compared to the total quantity of removing in Phragmitas communis and zizania caduciflora constructed system respectively. Temperature impacted on the romovel of TP, the removel rate of TP decreased 30% in the winter compared to summuer.
