Abstract: The treatment effect of sewage of artificial wetland and the submerged plant combination stabilization pond system under low,medium and high,three different hydraulic loading conditions was researched. The analysis was carried out on the hydraulic load effect on the performance of the combined system,and the contribution rate of each process structure. Results showed that the combined system’ s load resistant capability is strong enough to provide good treatment effect and stable effluent; the removal efficiency of pollutants except soluble phosphate reduced with the increase of hydraulic load,optimal removal effect under low hydraulic load was gained. Negative correlation existed between treatment effect of the artificial wetland and hydraulic load,while stabilization pond is not significantly affected by the hydraulic load; the nitrogen and phosphorus removal efficiency of pollutants of stabilization pond is better than that of the artificial wetland.
