PURPOSE : A method and an apparatus for gasification-combusting septic waste are provided to save costs required for treatment by using the septic waste as a heating source. CONSTITUTION : A method for gasification-combusting septic waste includes a drying process, a gasifying process, and a gasification-combusting process. The drying process includes the following : septic waste is introduced/stored/measured; the septic waste is heated/stirred, and evaporated air current is introduced into a combusting heat source; and the dried solid materials are discharged; the discharged solid materials are stirring-stored/pulverizing-supplied. The gasifying process includes the following : dried solid materials are oxidation-heated by supplying external air to form a heating layer; gas generated from the oxidation-heating process penetrates through the heating layer to discharge the solid materials; the solid materials are re-oxidation-heated to form a heating layer; and gas generated from the re-oxidation-heating process penetrates through the heating layer to discharge gas and the solid materials. The gasification-combusting process includes the following : combusting heat is generated; the combusting heat and a drying source are supplied; exhaust gas is condensed/dehydration-separated; and condensed water is discharged, and exhaust gas without moisture is returned.
