The invention discloses equipment and process for treating radioactive organic waste. The equipment comprises a double-layer rotary type pyrolysis gasification furnace, a secondary combustion chamber and radiation monitoring equipment, wherein the double-layer rotary type pyrolysis gasification furnace comprises a raw material inlet, a high-temperature flue gas inlet, a low-temperature flue gas inlet, a crude fuel gas outlet and an ash outlet; the secondary combustion chamber comprises an air inlet, a crude fuel gas inlet and a high-pressure flue gas outlet; the crude fuel gas outlet is communicated with the crude fuel gas inlet, the high-temperature flue gas inlet is communicated with the high-temperature flue gas outlet, the low-temperature flue gas outlet is communicated with a flue gas discharge pipeline, and the radiation monitoring equipment is arranged on the flue gas discharge pipeline. The equipment has the advantages that extra superheated steam needs not to be supplemented, the amount of flying ash carried in fuel gas is reduced greatly, the volume reducing ratio of radioactive waste is high, solid waste residues are stable, liquid and gas pollutants are not generated, and the equipment is clean, environmentally friendly, capable of achieving continuous production, good in economy and wide in application range.
