A process and system for enhanced nitrogen removal in a wetlands wastewater treatment facility is disclosed. Air is bubbled into the wetland to form an overall aerobic zone to enhance nitrification of the ammonia in the wastewater. A portion of the effluent is recycled back to the nutrient rich, anaerobic zone of the inlet of the wetland to enhance denitrification of the wastewater.
