Membrane Bioreactor (MBR) is a new type of wastewater treatment technology that combines high-efficiency membrane separation technology with biochemical technology. The membrane module directly performs solid-liquid separation in the biochemical pool, replacing the secondary sedimentation tank in the activated sludge method, and effectively achieves the purpose of muddy water separation. The high-efficiency retention effect of the membrane allows the nitrifying bacteria to be completely retained in the bioreactor, so that the nitrification reaction can be smoothly carried out, the ammonia nitrogen can be effectively removed, the sludge can be avoided, and the macromolecular organic matter which is difficult to degrade can be retained at the same time, and the The residence time of the reactor is maximized. After applying MBR technology, the main pollution removal rate can reach: COD≥93%, the suspended solids and turbidity are close to zero, the water quality is good and stable, and it can be directly reused to realize the sewage resource.
