Anaerobic ammonia oxidization granule sludge starting method for treatment of urban sanitary sewage

The invention relates to an anaerobic ammonia oxidization granule sludge starting method for the treatment of urban sanitary sewage, and belongs to the field of water environment restoration and regeneration. According to the method, an upflow anaerobic sludge bed is adopted by a reactor; volcanic rock fillers with the particle diameter of 4 to 5mm are filled in one fourth to one third volume of the upper part of the reactor and are inoculated with the mature anaerobic ammonia oxidation and nitrosation mixing sludge, i.e. the granule sludge is cultured gradually at the low filtering rate; next, the granule sludge is cultured in a strengthening manner by continuously raising the section filtering speed; the treatment capacity of the granule sludge is strengthened by changing the water quality; and finally the granule sludge can be used for the treatment of the sanitary sewage. After 145 days, the average particle diameter of the granule sludge reaches 2.0mm, so that the granule sludge is capable of treating the sanitary sewage of 40 to 50mg/L, i.e. the water quality of effluent water reaches 1A standard, and the load reaches 3kg/m3/d. Therefore, the method provided by the invention is suitable for the starting of an upflow anaerobic ammonia oxidization granule sludge reactor for the treatment of the urban sanitary sewage.
