Membrane bioreactor (MBR) is a new type of high efficiency wastewater treatment process, which integrates membrane separation technology and traditional biological treatment technology in recent years. Membrane separation process is used to replace gravity sedimentation process, regardless of the settling performance of solid particles. Both can complete the solid-liquid separation process, and can avoid the system failure caused by the loss of organism. Because of the complete separation of hydraulic retention time and sludge retention time in MBR, Therefore, the problem of sludge bulking is eliminated. The membrane bioreactor technology has many obvious advantages which can not be compared with the traditional biological treatment technology because of the high efficiency interception in the membrane separation process.
Characteristics and advantages
Standard modular design, intensive chemical plant production, reliable performance, stable water production, high quality.
The suspended matter and turbidity are close to zero and can be reused directly.
The biochemical degradation efficiency is high, the biochemical effect is good, the mud age is long, and the surplus sludge is few.
The density of the membrane assembly is high, and the two sink and mechanical filtration unit are omitted, and the area is small.
The component type is flexible and the maintenance and management is simple.
