The utility model discloses a catalyst molecular sieve high-temperature low-oxygen TPA (terephthalic acid) removal combustion treatment device. The device mainly comprises a fluidized bed furnace, a charging bin, a feeding device, a sealing blanking valve, a discharging device, a discharging device, an air regulating valve, a settling chamber, a filtering chamber, a combustor, a re-combustion chamber, a process heat exchanger, an induced draft fan, a cold flue baffle valve, a chimney, a cold smoke bypass baffle valve, a middle section discharging device, a high-temperature circulating fan, a high-temperature flue baffle valve, a mixer, an air flue baffle valve and an air blower. An air duct bypass baffle valve and an air suction opening. A TPA template agent in a molecular sieve framework is fully contacted with high-temperature low-oxygen flue gas in a fluidized bed furnace in a fluidized and suspended state for heat exchange and low-intensity combustion, so that collapse and damage of the framework due to t
