Abstract: PURPOSE: To clarify a waste liquid such as night soil with high efficiency, without necessity of dilution or any chemicals, by introducing the highly concentrated waste liquid into a reaction vessel provided with an aerator having a large oxygen-supply capacity, and then subjecting the waste liquid to nitrification-denitrification treatment under injection of an organic carbon source.  
     CONSTITUTION: A highly concentrated waste liquid 11, from which scum is removed by a scum-separator, e.g. a decanter or a drum screen, is introduced through a line 1 into this process, without being diluted. The waste liquid 11 flows into a reaction vessel 2 equipped with an aerator 7, e.g. a porous diffuser or a disc diffuser, having a larger oxygen-supply capacity than that of a conventional sparger to feed air 8 and adapting highly concentrated active sludge to conduct an undiluted reaction process. In the reaction vessel 2, BOD is removed from the waste liquid 11, and organic nitrogen and ammoniac nitrogen are concurrently oxidized and then reduced into N 2 .
