Rapid cultivation of simultaneous partial nitrification, anammox and denitrification (SNAD) granular sludge by inoculating CANON flocculent sludge and controlling setting time、HRT、DO and the composition of influent substrate (the ratio of synthetic wastewater and the actual sewage) was investigated in sequencing batch reactor. Then, the feasibility of SNAD granular sludge treating domestic sewage was investigated. The results showed that SNAD granular sludge could be cultivated within 34days, the maximum size of granular sludge reached 1103 μm and the total nitrogen removal rate reached 1.03kg/(m3·d). With the decrease of influent substrate, the nitrogen removal path of CANON always kept the dominant position in the reactor. And a simultaneous removal of C, N was achieved, with the average effluent TN was 10mg/L, the average effluent COD was 40mg/L. The water quality of effluent met the demand of the first grade A standards of Urban Sewage Disposal Plant Contamination Integrated Discharge Standard (GB18918-2002).
