NOVELTY - Processing high-concentration nitrogenous waste water using microorganism comprises passing nitrogenous waste water through the preprocessing system, first reaction system and second reaction system, at last, discharging the qualified effluent, passing pre-processed waste water through first reaction system into nitration reaction tank, separating slurry by particulate matter (PM) membrane, discharging sludge into sludge concentration tank, flowing supernatant into second reaction system, carrying out anaerobic ammonia oxidation reaction of upper clear liquid, reacting, and separating slurry.    USE - The method is useful for processing high-concentration nitrogenous waste water using microorganism (claimed).    ADVANTAGE - The method can control total nitrogen below 20 mg/l and chemical oxygen demand below 80 mg/l after processing high concentration nitrogen waste water, and can assure other index reach national standards.    DETAILED DESCRIPTION - Processing high-concentration nitrogenous waste water using microorganism, comprises passing nitrogen-containing waste water through the preprocessing system, the first reaction system and the second reaction system, at last, and discharging the qualified effluent, where the pre-processing system comprises oil removing device, uniform mixing device and air flotation device, in which passing sequentially pre-processed waste water through the device, entering waste water into the first reaction system, where the first reaction system comprises a reaction tank and particulate matter (PM) membrane, then passing through nitration reaction tank, after the reaction, separating slurry by PM membrane, discharging the lower layer sludge into sludge concentration tank and processing, flowing the supernatant into the second reaction system and processing, where the second reaction system comprises anaerobic ammonium oxidation (Anammox (RTM: Anaerobic ammonium oxidation)) reaction tower and PM film, flowing upper layer clear liquid through anaerobic ammonium oxidation reaction tower and carrying out anaerobic ammonia oxidation reaction, reacting again waste water, separating slurry by the PM membrane, and finally reaching the standards.
