Overview
The membrane bioreactor is an efficient sewage treatment system that integrates membrane separation technology and biological treatment technology. Its core consists of a biological reaction unit and a membrane separation unit, and solid-liquid separation is achieved through negative pressure suction filtration. It is widely used in municipal sewage regeneration, industrial wastewater treatment, decentralized water supply, and seawater desalination pretreatment.
Note: The microstructure of the outer surface of the membrane is 40,000 times
Working Process
Features
High-efficiency purification efficiency
The membrane pore size of the membrane bioreactor is ≤0.1μm, which has a physical interception effect, can completely separate suspended matter, bacteria, and macromolecular organic matter, meantime promote the enrichment of nitrifying bacteria, and enhance the biodegradation ability, so that the effluent SS <5mg/L (conventional process is about 20mg/L), turbidity <0.5NTU, COD removal rate >95%, ammonia nitrogen removal rate >98%
Space intensive
By integrating biological treatment and solid-liquid separation functions, the membrane bioreactor eliminates the secondary sedimentation tank and deep treatment unit. Compared with traditional processes, the floor area is reduced by 40-60%, particularly suitable for scenarios with tight land resources or rapid deployment.
Intelligent operation and maintenance
The PLC+SCADA system in the membrane bioreactor monitors water quality parameters in real-time, automatically adjusts key indicators such as aeration volume and membrane flux, and reduces manual intervention.
Anti-fouling design
The membrane bioreactor slows down the membrane fouling rate and maintains the membrane flux (10-40L/m²·h) by optimizing the membrane wire spacing (large channel design) combined with intermittent operation (8 minutes of water production + 2 minutes of shutdown).
