Abstract

본 발명은 환경오염원으로서 큰 부분으로 차지하는 사람, 가축의 분뇨나 기타 고농도 유기오수를 액상부식법에 의하여 고액분리한 후 액체부분을 방류수 수질기준에 적합한 정수가 되도록 처리함에 있어서 방류정수내의 질소화합물을 효과적으로 처리제거하는 고농도 유기 오수의 질소제거방법에 관한 것으로, 특히 선출원된 특허출원 제92-1307호의 개량에 관한 것이다.The present invention relates to a method and apparatus for separating nitrogenous compounds in discharged water by treating a liquid portion of a human body, livestock manure, or other highly concentrated organic wastewater, which is a major part of environmental pollution sources, 0001] This invention relates to a method for removing nitrogen in high-concentration organic wastewater which effectively removes the nitrogen from the wastewater, and more particularly to the improvement of the above-mentioned patent application No. 92-1307.

고농도 유기오수의 질산화와 질소제거를 단일조에서 동시에 수행하지 않고 액상부식조를 호기성액상부식조와 혐기성액상부식조로 각각 분리 구성시켜 투입된 유기오수가 상기 혐기성액상부식조에서 교반되어져 질소를 제거되게 하며, 호기성액상부식조로 이송되어 폭기에 의해 질산화와 탈질에 관여하는 호기성미생물(질산화균)과, 혐기성미생물(탈질균) 각각의 균체내의 적응기간을 없애 환경에 적응하는데 따른 시간의 지체없이 탈질화시키는 것을 특징으로 한다.The nitrification and nitrogen removal of the high concentration organic wastewater are not simultaneously performed in a single tank, but the liquid corrosion tank is separated into the aerobic liquid tank and the anaerobic tank by separating the organic ozone into the anaerobic tank, (Denitrifying bacteria) and anaerobic microorganisms (denitrifying bacteria), which are transferred to the liquid phase corrosion tank, are denitrified without delay in the adaptation to the environment by eliminating the adaptation period in the cells of the aerobic microorganisms do.
