The invention relates to a method for removing organic waste gas containing waste gas low in spontaneous ignition point. Organic waste gas containing high-concentration waste gas low in spontaneous ignition point is subjected to water absorbing operation after being subjected to low-temperature thermal oxidation pretreatment, and therefore acid gas is removed; and the waste gas with the acid gas removed is fed into RTO to be treated. According to the method, generation of RTO 'heat accumulation layer combustion' is reduced through the treatment method that the organic waste gas containing the high-concentration waste gas low in spontaneous ignition point enters the RTO after being subjected to low-temperature thermal oxidation pretreatment, and the method for removing the organic waste gas containing the waste gas low in spontaneous ignition point has the beneficial effects of being high in organic waste gas treatment efficiency, easy and convenient to operate, and small in equipment corrosiveness.
