NOVELTY - Anaerobic ammonia oxidation and heterotrophic denitrification of ammonia sludge, comprises inoculating ammonia granular sludge, adding PVC spherical filler in a reactor, at first stage, adding (a) ammonium chloride, (b) sodium nitrite, (c) sodium bicarbonate and (d) organic phenol, adding oxidized and denitrified bacteria and then culturing, adding of ammonia nitrite and nitrogen and then cultivating the bacteria, at second stage adding (a)-(d), and then culturing, inoculating a sludge to a red mud and white mud, and independently scanning the muds to observe mixed bacteria.    USE - The method is useful for anaerobic ammonia oxidation and heterotrophic denitrification of ammonia sludge (claimed).    DETAILED DESCRIPTION - Anaerobic ammonia oxidation and heterotrophic denitrification of ammonia sludge, comprises inoculating ammonia granular sludge with a concentration of 1000-2000 mg mixed liquor volatile suspended solid (MLVSS)/l, adding PVC spherical filler in an upper part of a reactor with a diameter of 10 cm, controlling the filling rate to 30-50%, at first stage, adding ammonium chloride, sodium nitrite, sodium bicarbonate and organic phenol, converting concentration of phenol into chemical oxygen demand (COD) concentration, adding oxidized and denitrified bacteria and then culturing, adding of ammonia nitrite and nitrogen with a COD concentration of 50-70, 80-100 and 20-30 mg/l, adjusting a pH value to 7-8 by adding sodium bicarbonate, adjusting water inlet flow rate at hydraulic retention time (HRT) of 1.5-3 hours using water inlet peristaltic pump, temperature of 20-30 degrees C by a temperature control system including a bed reactor and then cultivating the bacteria for 30-60 days, and entering into next stage when the removal rate of ammonia nitrite and nitrogen is 40-50%, the concentration of the ammonia nitrite and nitrogen is gradually increased, and concentration of the phenol is 20-30 mg/l, at second stage adding ammonium chloride, sodium nitrite, sodium bicarbonate and organic phenol, adding of ammonia nitrite and nitrogen with a COD concentration of 50-70, 80-100 and 40-30 mg/l, and then culturing when the removal rate of ammonia nitrite and nitrogen is greater than 80% and then culturing for 30-60 days using 7-10 mg/l of ammonia nitrite and nitrogen, culturing and observing by digital photo, inoculating a sludge to a red mud and white mud coated with white and red fungus, and independently scanning the red mud and white mud using electron microscope to observe mixed bacteria.
