A membrane bioreactor (MBR) is a new and efficient wastewater treatment and reuse process that integrates membrane separation technology with traditional biological wastewater treatment processes. In recent years, it has gained increasing attention in the international water treatment technology field. The membrane separation device is placed in the reactor to filter the sludge-containing wastewater in the biological reaction tank, which can retain activated sludge and large molecular organic substances, achieving sludge-water separation. This also significantly increases the concentration of activated sludge in the reactor, greatly improving the degradation efficiency of the biochemical reaction. The combination of membrane separation and biological treatment processes results in high-efficiency and high-quality effluent, making the membrane bioreactor one of the most advanced and promising wastewater treatment technologies in the world.
