PURPOSE : A pure oxygen aerating apparatus and a sewage and wastewater treating apparatus including the same are provided to increase the using efficiency of oxygen by measuring the concentration of non-used oxygen and transferring the non-used oxygen to an inner collecting panel if the concentration is higher than a pre-determined value.CONSTITUTION : A pure oxygen aerating apparatus(200) is floated on the surface of water in a reacting bath(110) storing sewage and wastewater. The apparatus includes an impeller(230), a first collecting panel(210), and a second collecting panel(220). The impeller pulverizes oxygen and transfers the pulverized oxygen into the sewage and the wastewater in the reacting bath. The first collecting panel collects non-pulverized oxygen and re-supplies the collected oxygen to the impeller. The second collecting panel collects materials generated from the microorganism metabolism of the pulverized oxygen.COPYRIGHT KIPO 2013
