The A/O integrated device for treatment of domestic wastewater in small cities

When domestic wastewater is treated by the A/O integrated equipment developed in this project, the COD, BOD, ammonia nitrogen and total phosphorus in the effluent will meet the A-Class of Standard I (COD less than 50mg / L, BOD less than 20 mg / L, Ammonia less than 8 mg / L, total phosphorus less than 1 mg / L). The equipment is compact in structure, occupies a small area and saves energy.
