Do you know the process of MBR integrated equipment processing?

Ħin: 2020-04-17 Viżti: 6

MBR (Membrane Bioreactor) is a combined process that combines biological treatment and membrane separation. A hollow fiber membrane module is placed in the bioreactor. The hollow fiber membrane is ultrafiltration (UF) with a pore size range of 0.04 μm, mainly used to intercept suspension and organic matter. Its characteristics can maintain a certain concentration of microorganisms in the biological reaction tank and purify the sewage.


MBR membrane bioreactor is a new type of high-efficiency sewage treatment process that combines high-efficiency membrane separation technology with traditional activated sludge process. It is placed in an aeration tank with MBR membrane module with unique structure. The biologically treated water is filtered by a pump through a filter membrane and then extracted. MBR sewage treatment is very different from the traditional sewage treatment method. The membrane separation device replaces the secondary sedimentation tank and tertiary treatment process in the traditional process. Therefore, high-quality effluent is obtained, which solves the problem that the effluent quality of sewage treatment by traditional environmental protection equipment does not meet the requirements of reclaimed water reuse. The water after MBR sewage treatment can be directly used as municipal water or further treated as various industrial water.

The presence of MBR membrane greatly improves the capacity of solid-liquid separation of the system, so that the effluent, water quality and volume load of MBR membrane bioreactor are greatly improved, and the water quality standard after membrane treatment is high (more than the national level A Standard), after sterilization, finally form high-quality recycled water with high water quality and biological safety, which can be directly used as a new water source.

Due to the filtration effect of the membrane, the microorganisms are completely trapped in the MBR membrane bioreactor, which realizes the complete separation of the hydraulic retention time and the activated sludge age, eliminating the problem of sludge expansion in the traditional activated sludge method. MBR membrane bioreactor has high removal efficiency of pollutants, strong nitrification ability, can simultaneously perform nitrification, denitrification, good denitrification effect, stable effluent water quality, low residual sludge output, compact equipment, and small footprint (only traditional (1 / 3-1 / 2 of the process), easy incremental expansion, high degree of automation, simple operation and other advantages.

The MBR membrane bioreactor assembly series has the advantages of compact structure, beautiful appearance, small footprint, low operating cost, stable and reliable, high degree of automation, and convenient maintenance and operation. The effluent quality of MBR sewage treatment is good, better than the water quality standard of reclaimed water, and it is the international advanced sewage treatment product equipment. The series of membrane modules of the MBR membrane bioreactor has formed a standardized series of products. Each module is composed of several standard membranes. It can also be individually designed according to user needs to meet user needs.

MBR integrated equipment uses membrane bioreactor (MBR) for wastewater treatment and reuse. It has all the advantages of membrane bioreactor: good effluent quality, low operating cost, strong impact resistance, and sludge volume Less, high degree of automation, in addition, as an integrated device, it has a small footprint and is easy to integrate. It can be used not only as a small-scale sewage recycling equipment, but also as a core treatment unit of a larger sewage treatment plant (station). It is one of the hotspots in the field of sewage treatment and has broad application prospects.
