Abstract

본 발명은 생물학적 교대반응공정에서 각종 폐수 특히 요수를 폭기, 무산소 및 침전공정을 교대로 거치면서 폐수를 처리하는 생물학적 교대반응에 의한 오·폐수처리 방법에 관한 것으로, 종래에도 많은 내용의 기술이 있었으나, 처리장내의 악취로 인한 2차적환경오염을 야기시키는 문제가 있었고, 또한 처리를 위한 시설물의 구조물을 각 공정별로 별도로 시설하여 사용했기 때문에 많은 공간의 확보 및 시설에 따른 부담율이 높은 문제점이 있었다.The present invention relates to a wastewater treatment method by a biological shift reaction for treating wastewater by aeration, anaerobic and sedimentation of various wastewaters, particularly urea, in a biological shift reaction process. In addition, there was a problem of causing secondary environmental pollution due to odor in the treatment plant, and there was a problem of securing a lot of space and a high burden rate according to the facility because the structure of the facility for treatment was used separately for each process.

본 발명은 이러한 문제점을 근본적으로 제거하기 위하여 창출된 것으로, 특히 오·폐수에 존재하는 유기물을 폭기공정, 무산소공정 및 침전공정으로 하나의 교대반응조에서 교대로 반복처리하여 질산성질소(NO3-N), 암모니아성질소(NH3-N)를 각각 질소로 방출시키거나 질산성질소로 변화되면서 인의 축적이 일어나도록 하여 유기물질의 침강을 유도 제거하여 오·폐수를 처리하는데 있다.The present invention is, more particularly, aerating the organic matter present in the wastewater process, an oxygen-free process and the precipitation process, the nitrate nitrogen by repeating processing alternately in a shift reactor to generate in order to fundamentally eliminate the above problems (NO 3 - N) and ammonia nitrogen (NH 3 -N) are released to nitrogen or changed to nitrate nitrogen, respectively, to cause phosphorus accumulation to induce and remove sedimentation of organic materials to treat sewage and wastewater.
