Membrane bioreactor (MBR) is a new type of sewage treatment technology that separates and filters the muddy sewage in the biochemical reaction tank through hollow fiber membrane components, combining membrane separation technology with activated sludge biotechnology.
Technical advantages
MBR process can efficiently separate activated sludge and water. The sludge retained by the membrane can be returned to the biochemical pool, which can increase the sludge concentration of the biochemical pool by more than one time, thereby improving the biochemical efficiency of the biochemical pool and enhancing the degradation effect of pollutants. At the same time, the high-precision filtration of the membrane can efficiently ensure the water quality of the produced water, and the produced water can be reused after disinfection.
Typical applications
It is widely used in reverse osmosis system pretreatment, municipal sewage treatment and reuse, municipal building reuse water, industrial organic wastewater treatment and reclaimed water reuse, garbage leachate and other water treatment.
MBR membrane bioreactor: an efficient sewage treatment technology With the rapid development of industrialization and urbanization, sewage treatment has become an increasingly important issue.
MBR membrane bioreactor, as an advanced sewage treatment technology, has received widespread attention in recent years.
MBR combines membrane separation technology and biological treatment technology, which can effectively remove organic matter, nitrogen, phosphorus and other pollutants in sewage and achieve efficient sewage purification.
1. Basic principles of MBR membrane bioreactor MBR membrane bioreactor mainly consists of two parts: bioreactor and membrane separation component.
Microorganisms in the bioreactor generate bioenergy by degrading organic matter in sewage and remove pollutants at the same time.
The membrane separation component retains microorganisms in the reactor by physical interception, while allowing the treated water to flow out through the membrane, thereby achieving solid-liquid separation and sewage purification.
2. Advantages of MBR membrane bioreactor MBR technology has the following significant advantages over traditional activated sludge method:
(1) High effluent quality: MBR technology can completely remove suspended solids, bacteria and viruses in sewage through the efficient interception of the membrane. The effluent water quality is clear and transparent, meeting various reuse requirements.
(2) Small footprint: MBR technology combines biological reaction and membrane separation process, which greatly reduces the reactor volume and is suitable for urban areas with tight land resources.
(3) Low sludge production: The sludge in the MBR reactor is relatively old, the sludge production rate is low, and the sludge has good settling properties and is easy to handle.
(4) Flexible operation: MBR technology can flexibly adjust operating parameters according to changes in water quality to achieve stable operation.
(5) Easy to achieve automated management: The operation monitoring of the MBR system is relatively simple, which facilitates automated control and remote monitoring.
