Membrane Bioreactor, or MBR for short, is a water treatment technology that is a highly efficient biochemical water treatment technology that combines biotechnology and membrane technology. Membrane Bioreactor is an efficient wastewater treatment technology that combines membrane separation technology and traditional sludge method. Due to the filtering effect of the membrane, the organisms are completely trapped in the bioreactor, achieving a complete separation of the hydraulic retention time and the sludge age, and maintaining a high MLSS in the bioreactor. Strong nitrification ability and high pollutant removal rate.
Membrane bioreactor is a new water treatment technology combining high-efficiency membrane separation technology and activated sludge method. The application of hollow fiber membrane replaces the secondary sedimentation tank in the activated sludge method for solid-liquid separation, which effectively achieves the purpose of mud-water separation. Make full use of the high-efficiency retention of the membrane, which can effectively retain the nitrifying bacteria, and completely retain it in the bioreactor, so that the nitrification reaction can be carried out smoothly, effectively remove ammonia nitrogen, avoid the loss of sludge, and can trap macromolecular organic compounds that are difficult to degrade for a while , Extend its residence time in the reactor, so that it can get the maximum decomposition. After applying MBR technology, the removal rate of main pollutants can reach: COD≥93%, SS = 100%. The effluent suspended solids and turbidity are almost zero, and the treated water quality is good and stable, which realizes the recycling of sewage.
MBR integrated equipment is an integrated equipment that uses membrane bioreactor (MBR) for wastewater treatment and reuse. It has all the advantages of membrane bioreactor: good effluent water quality, low operating cost, strong system impact resistance, sludge Small amount, high degree of automation, etc. In addition, as an integrated device, it has a small footprint and is easy to integrate. It can be used as both a small sewage reuse equipment and a core treatment unit of a larger sewage treatment plant (station). It is one of the current hotspots in the field of sewage treatment and has broad application prospects.
Suitable for residential sewage, office buildings, shopping malls, hotels, restaurants, institutions, schools, troops, factories and other domestic sewage and similar industrial organic wastewater, such as organic sewage in textile, beer, paper, tanning, food, chemical and other industries deal with.
