Process and system for enhanced nitrogen removal in a wetland and recirculating sand filter wastewater treatment system |
摘要 |
A process and system for enhanced nitrogen removal in a wastewater treatment facility comprises a constructed wetlands and a recirculating sand filter. The effluent from the constructed wetlands passes through the recirculating sand filter to facilitate ammonia conversion to nitrates. A portion of the wastewater is recycled from the recirculating sand filter to the constructed wetlands to provide for anaerobic denitrification of the wastewater in a nutrient rich environment.
