The utility model relates to an automated sequential reaction device used for cultivating and researching aerobic granular sludge, which is characterized in that the utility model comprises a reactor body, a stirring system, an aerating system and a control system, wherein, the proportion of the height of the reactor body and the diameter of a barrel body is more than 10; the reactor body is provided with a water inlet, a sampling opening and a water discharging opening, which can be controlled to be opened and closed by the control system, and the bottom is provided with a sludge discharging opening. The stirring system is arranged in an inner cavity of the reactor body; a micropore aeration head of the aerating system is arranged at the bottom of the reactor body and is connected with a blower and a nitrogen system, which are controlled by the control system through air delivery pipelines. The middle lower position of the reactor body is also provided with a heating system which comprises a heating jacket which coats the middle lower part of the reactor body. The heating jacket is provided with a water inlet and a water outlet, and is connected with a water pump and a hot water source with a constant temperature through pipelines. The utility model can fast cause granular sludge to be formed, and simultaneously can realize different test purposes of the research, the cultivation, the nitrification and denitrification, the denitrifying phosphorus removal of granular sludge, etc. The operation is simple and convenient.
