The invention discloses an anaerobic ammonia oxidation-coupled denitrification composite denitrification system and a quick starting method. The system is composed of an anoxic tank and an anaerobic tank, the anoxic tank performs periodic aeration through an aeration pump, a sequencing batch operation mode is adopted, the anaerobic tank is an up-flow sludge bed reactor, the anoxic tank mainly performs partial nitrosation, and effluent enters an anaerobic device for next anaerobic ammonia oxidation and denitrification reaction. According to the invention, a matrix formula without organic matterin inlet water is adopted; by gradually shortening the hydraulic retention time (from 7h to 4h) and precisely regulating and controlling dissolved oxygen based on the nitrogen form in the process, aseed sludge system taking denitrification as a main denitrification path is quickly cultured into a denitrification system taking anaerobic ammonia oxidation as a main part and denitrification as an auxiliary part.
