Description

Technical Field

[0002] In the field of sewage treatment and water resource reuse, MBR, also known as membrane bioreactor, is a new water treatment technology that combines membrane separation unit with biological treatment unit. Membrane Bio-Reactor (MBR) is a new type of wastewater treatment system that organically combines membrane separation technology with biological treatment technology. The membrane component replaces the terminal secondary sedimentation tank of traditional biological treatment technology, maintains a high concentration of activated sludge in the bioreactor, increases the organic load of biological treatment, thereby reducing the footprint of sewage treatment facilities, and reduces the amount of residual sludge by maintaining a low sludge load. The membrane separation equipment is mainly used to intercept the activated sludge and macromolecular organic matter in the water. Due to its effective interception effect, the membrane bioreactor can retain microorganisms with a long generation cycle, and can achieve deep purification of sewage. At the same time, nitrifying bacteria can fully reproduce in the system, and its nitrification effect is obvious, which provides the possibility of deep phosphorus removal and nitrogen removal.
