Disclosed are a method and device for realizing advanced nitrogen removal of mature landfill leachate and sludge reduction by using sludge fermentation products as carbon source, belonging to the field of biological treatment of sludge of high ammonia nitrogen wastewater. The mature landfill leachate first enters a PNA-SBR, the reactor operates in an anoxic/anaerobic/oxic (A/A/O) mode, denitrification is performed at an anoxic state; then anaerobic ammonia oxidation is performed at an anaerobic stage to remove part of ammonia nitrogen and nitrite nitrogen; partial nitrification is performed at an oxic stage to remove the ammonia nitrogen; discharged water is pumped into a DN-SBR, meanwhile, an excess sludge fermentation mixture is added, the reactor operates in an anoxic/anaerobic/oxic (A/A/O) mode, organic matters in the sludge fermentation mixture are used for denitrification at an anoxic stage, and meanwhile, microorganisms store an inner carbon source; ammonia nitrogen brought by the fermentation mixture is removed at an anaerobic stage; and denitrification is performed through the inner carbon source at an oxic stage. The remarkable sludge reduction effect is achieved while a removal rate of TN achieves 96.0%, and the method and the device are suitable for advanced removal of the high ammonia nitrogen wastewater.

An apparatus for treating municipal sewage by anaerobic/aerobic/anoxic (AOA) [1] process via simultaneous endogenous partial [2] denitrification coupled with anammox in anoxic zone is disclosed. The apparatus mainly includes a raw water tank () for sewage, an AOA reactor () and a sedimentation tank (), the sludge flows back from the bottom of the sedimentation tank () to the anoxic zone () and the anaerobic zone () respectively, and biofilm filler is added to the anoxic zone (). The sewage enters the AOA reactor (), and the intracellular carbon source is stored in the anaerobic zone () to remove the organic matter in the raw water. Then it enters the aerobic zone () for nitrification, and the generated nitrate-nitrogen enters the anoxic zone () for endogenous partial denitrification. The filler in the anoxic zone () uses the generated nitrite-nitrogen by endogenous partial denitrification and the remaining ammonia-nitrogen in the raw water to perform anammox reaction. The generated nitrate-nitrogen can be further removed by endogenous denitrification in the anoxic zone (). Endogenous partial denitrification coupled with anammox is used for nitrogen removal in the anoxic zone (), which can reduce the requirement of aeration in the aerobic zone () and the carbon sources in the anoxic zone (), and suitable for low C/N ratio municipal sewage treatment. A method for treating municipal sewage by AOA process via endogenous partial denitrification coupled with anammox in anoxic zone is also provided.
