Integrated wastewater treatment equipment utilizes processes such as A/O, A2/O, or A/O-MBR, combining biological degradation, sedimentation, optional disinfection, and other treatment steps into a compact, unified system. It is designed to treat domestic wastewater and industrial wastewater with similar characteristics. The equipment features a space-saving design with a small footprint and can be fully installed underground. It operates efficiently, offers strong resistance to shock loads, delivers high treatment performance, and is easy to operate and maintain. The treated effluent maintains stable quality and complies with Class A or B standards as defined in the Discharge Standard of Pollutants for Municipal Wastewater Treatment Plants (GB18918-2002). Installation options include underground or above-ground placement, with standard treatment capacities ranging from 24 to 500 m³/d. For larger capacities, custom solutions are available.
