Introduction to biological aerated filter

The aerated biological filter is abbreviated as BAF, which is a new type of biological membrane wastewater treatment process developed in Europe and the United States in the late 1980s. The process has the functions of removing SS, COD, BOD, nitrification, denitrification, phosphorus removal, and AOX (hazardous substances) removal. It is characterized by integrating biological oxidation and interception of suspended solids into one, saving subsequent sedimentation tanks (secondary sedimentation tanks) Compared with other secondary biochemical treatment technologies, it has high volume load, strong impact load resistance, good treatment effect, good removal effect on carbon source pollutants and nitrogen source pollutants, small footprint, and treatment process. It has the advantages of simplicity, capital construction cost, operating cost saving and simple management, and high degree of automation. The related equipment of the biological aerated filter can be controlled by a computer. The operating data and parameters can be displayed on the computer. The computer program can realize the automatic control of the operating equipment. It can be called a true mechatronics sewage treatment equipment, which is easy to operate. And management.
