A device and method for enhancing nitrogen and phosphorus removal based on a multistage AO partial denitrification coupled with Anammox process in combination with a sludge hydrolytic acidification mixture belong to the technical field of active sludge method wastewater treatment. A system includes a water tank, a water pump, a biochemical reaction zone, a hydrolytic acidification tank and other devices. A multistage AO step-feed pipeline is used to inject raw water into the reaction zone in a segmented manner, guaranteeing efficient utilization of organic matter in the raw water; biofilm carriers are added into an anaerobic zone and anoxic zones to enrich anammox bacteria, and nitrite nitrogen produced by partial denitrification provides a substrate for the anammox bacteria to realize autotrophic nitrogen removal; a nitrification and phosphorus accumulating bacteria aerobic phosphorus uptake are performed in aerobic zones; and part of excess sludge in a secondary sedimentation tank enters the hydrolytic acidification tank to convert macromolecular organic matter into low molecular weight organic matter, a hydrolytic acidification mixture and the excess sludge in the secondary sedimentation tank synchronously flow back to the anaerobic zone, and as a high-quality carbon source, the low molecular weight organic matter can promote partial denitrification. The system provides a novel method for efficient and energy-saving treatment of municipal wastewater.

The present application provides a system and method for realizing partial anammox advanced nitrogen and phosphorus removal through mainstream and sidestream biofilm cyclic alternating for a municipal wastewater treatment plant. The system includes three main component units: a mainstream zone (a), an advanced treatment zone (b) and a side stream zone (c). Advanced nitrogen and phosphorus removal of the entire system is realized through cyclic alternating of biofilms. In the mainstream zone (a), the main function of an anaerobic/anoxic zone is to perform heterotrophic denitrification nitrogen removal, and partial denitrification/anammox autotrophic nitrogen removal, and the main function of an oxic zone is to remove organic matter, perform aerobic phosphorus uptake, and complete a nitrification reaction. In a denitrification fluidized bed () in the advanced treatment zone (b), advanced treatment is performed for a mixed solution of effluent and raw water in the mainstream zone to achieve heterotrophic denitrification, and partial denitrification/anammox autotrophic nitrogen removal. A high-ammonia nitrogen anammox nitrogen removal zone () in the sidestream zone (c) enriches anammox bacteria based on biofilms, realizing autotrophic nitrogen removal of sidestream high-ammonia nitrogen wastewater.
