MBBR Bio Filler Extrusion Line 1) Partial denitrification by external return sludge; A small part of the wastewater to be treated by biochemical treatment enters the pre anoxic tank through the one point inlet channel, while the external return activated sludge from the subsequent secondary sedimentation tank treatment unit enters the pre anoxic tank through the external return channel. The organic matter in the influent of the one point inlet channel and the carbon source degraded by internal respiration are used in the pre anoxic tank to denitrify the NO3 -- N brought by the reflux activated sludge; 2) In anaerobic phosphorus removal, most of the wastewater to be treated goes into the anaerobic tank through the two-point inlet channel. Without dissolved oxygen and NO3 -- N, the phosphorus accumulating bacteria in the anaerobic tank can absorb the easily degradable organic matter brought in by the two-point inlet channel by using the energy stored in the body and store it in the form of PHB; In the subsequent activated sludge aerobic tank and MBBR sludge membrane aerobic tank, the phosphorus accumulating bacteria can oxidize and metabolize the PHB stored in the body by molecular oxygen or combined oxygen, and generate energy, so as to absorb excessive phosphate from sewage, and the excessive phosphorus accumulating bacteria will be discharged into the biological pool along with the discharge of excess sludge to achieve the purpose of biological phosphorus removal 3) During anoxic denitrification, the effluent from the anaerobic tank enters the anoxic tank. At the same time, the internal return nitrification liquid from the internal reflux device of MBBR flows into the anoxic tank through the internal return channel of nitrification liquid. Denitrifying bacteria in the activated sludge can make full use of the easily degradable organic matter in the influence for denitrification and denitrification, so as to remove NO3 --N in the internal return nitrification liquid, so as to achieve the purpose of deep denitrification.
