PURPOSE: A sewage disposal device using a hollow complex carrier and a method thereof are provided to prevent degradation of dentrificaion and dephosphorization efficiency due to dissolved oxygen, and to retreat remaining nitrogen and phosphorous in sewage. CONSTITUTION: A sewage disposal device(100) using a hollow complex carrier includes the following: a screen tank(110) eliminating adulteration included in sewage; an anaerobic tank separating phosphorus in sewage supplied from the screen tank and a denitrification tank; an anoxic chamber denitrating the nitrogen in the sewage which is transferred from a sewage and a contact oxidation tank(140); the contact oxidation tank removing the remaining nitrogen and the phosphorous; a settling tank(150) discharging the sludge; and a denitrification tank removing the nitrogen included in the sludge. The contact oxidation tank includes a diffuser and the hollow complex carrier. |
