Abstract

본 발명은 미국에서 특허만기로 종료된 밀폐식 순산소폭기법(UNOX)과 영국의 BOC사 특허인 개방형폭기법(VITOX)과의 장점만을 도입하여 고안한 것으로서 UNOX의 압력이용과 VITOX의 폭기조의 개방화등 양쪽의 이점을 취하였다.The present invention was devised by introducing only the advantages of the closed oxygen aeration method (UNOX) and the BOC patented open aeration method (VITOX) in the United States, and the UNOX pressure and VITOX aeration opening It has taken advantage of both.

공기중의 산소를 이용하던 종래의 폭기방식에서 순산소만을 분리하여 직접 주입하는 순산소법은 동력 전달효율이 높고 폭기조의 크기를 현저하게 줄일수 있는 방법으로 부지의 부족 및 반응기의 고효율을 기하기 위하여 시도되는 미래의 공법으로 여기에 산소의 용해도가 극히 낮음에 비추어 압력으로 강제 주입하여 헨리법칙에 따라 압력에 비례하여 용해하는 성질을 이용하였고, 반응기를 개방형 폭기조, 중류탑형, U튜브형, 심정이용법 등의 반응기를 이용하여 종래의 방법과 현저히 고효율의 방법을 취하여 고안하였다.In the conventional aeration method that used oxygen in the air, the pure oxygen method that directly injects pure oxygen by injecting only oxygen directly has high power transmission efficiency and can significantly reduce the size of the aeration tank. In the future, the method is used to force the injection into the pressure in the light of the extremely low oxygen solubility, and to dissolve it in proportion to the pressure according to Henry's law. The reactor was designed using a conventional method and a method of remarkably high efficiency.

이는 종래의 폭기조가 배제된 폐수 및 오수처리장의 화학플랜트화가 가능하게 된 계기가 될 것이다.This will be an opportunity to enable chemical plantation of wastewater and sewage treatment plants without the conventional aeration tank.
