The principle is to fill the reactor with high specific surface area As the carrier of microbial growth, the inside of the filter is aerated. When the sewage flows through, the organic matter in the sewage will biochemically react with the biofilm on the surface of the filler. At the same time, the interception between the granular fillers is used to remove the suspended matter in the water to achieve purification Purpose, its biggest feature is that it integrates biological oxidation and interception of suspended solids, saving subsequent sedimentation tanks. With the advancement of technology, biological aerated filters that integrate the anaerobic zone and the aerobic zone for simultaneous nitrification and denitrification reactions have emerged, but there are still some disadvantages: the aerobic zone and the anaerobic zone are set in the same device Internally, the anaerobic nitrification and denitrification reactions cannot be carried out efficiently, resulting in the effluent not meeting the requirements of the first-level standard; the current biological aerated filter generally requires that the COD value is not higher than 500mg/L, but the mixed industrial and domestic sewage of oil and gas fields usually contains For oil, the COD value is high, and the existing biological aerated filter is not suitable for treatment.
