Zusammenfassung:	To solve a problem that a conventional wastewater treatment apparatus using microorganisms cannot efficiently treat wastewater containing a nitrogen compound.SOLUTION: A wastewater treatment apparatus (100) includes a reaction vessel (51) for treating wastewater and a gas supplier (10) placed submerged in wastewater in the reaction vessel (51). The gas supplier (10) supplies oxygen-containing gas to the wastewater from an inside and carries nitrifying bacteria on an outer surface in contact with the wastewater.SELECTED DRAWING: Figure 4 【課題】従来の微生物を用いた廃水処理装置では、窒素化合物を含有する廃水を効率的に処理することができなかった。【解決手段】廃水処理装置（１００）は、廃水を処理する反応槽（５１）と、反応槽（５１）中で、廃水に浸漬して配置される気体供給体（１０）と、を含む。気体供給体（１０）は、酸素を含む気体を内側から廃水に供給し、かつ、硝化菌を廃水に接する外側表面に担持する。【選択図】図４
