Background

In the process of the biological aerated filter, biological aerated treatment and filtration are important links. When the biological aerated filter operates, the biological aerated filter has the functions of biological degradation treatment and filtration. The process of the biological aerated filter requires uniform water and gas distribution, and simultaneously requires uniform aeration and oxygen supply for microorganisms in water, along with the increase of the pollutant interception amount of a filter material layer, the sludge permeability is deepened, so that the filtering speed is reduced, the resistance of the filter is gradually increased, and the turbidity of the filtered water is increased. In order to restore the normal operation of the filter and ensure the quality and quantity of the effluent water, back flushing is required. The back washing is carried out by three stages of air washing, air-water combined washing and water rinsing, and the process is finished by a special filter head. And the filter structure comprises a water distribution system, an air distribution system, an aeration system and a filter material system.
