In recent years, with the increasingly prominent problems of water pollution and water resources shortage, membrane technology is widely used in the field of water treatment MBR membrane Technology has attracted much attention. MBR membrane technology, fully known as Membrane Bio Reactor technology, refers to the realization of liquid purification and solid-liquid separation through membrane separation technology. At the same time, combined with bioreactor technology, it makes the water treatment process efficient, stable, reliable, free of secondary pollution and other significant advantages, and is widely used in wastewater, garbage leachate, municipal water and other fields. MBR membrane technology strengthens the treatment effect of wastewater, improves its quality, and provides a strong guarantee for the protection and reuse of water resources. MBR membrane is widely used in major water treatment plants, especially in beverage plants and food industries, which produce a large amount of industrial wastewater. The proportion of MBR technology is increasing year by year. In addition to the industrial field, MBR membrane technology is also important in the field of domestic sewage treatment. Now, more and more cities use MBR membrane technology to treat sewage to meet discharge standards. For example, some sewage treatment plants in Beijing, Guangzhou and other cities use MBR membrane technology. MBR membrane technology also has other advantages. Due to its special structure, it can effectively remove most suspended solids and precipitated substances, improve the biological reaction efficiency, and achieve high quality treatment. Moreover, MBR membrane technology also reduces the use of chemicals in traditional water treatment and reduces the treatment cost. In the future, MBR membrane technology will play an important role in the field of water treatment. At the same time, as an advanced environmental protection technology, the application of MBR membrane technology needs to be further promoted and improved. We believe that with the continuous development of technology and the progress of the times, MBR membrane technology will play a more important role in meeting the needs of water resources and environmental protection.
