Abstract

유기성 하수, 오폐수의 회분식 자연정화 방법 및 그 장치에 관한 것으로, 종래에는 한공정에서 침전시킨 후 방류할 시에는 침강성이 불량한 물질이 그대로 부유된 상태로 배출되기 때문에 방류수의 수질을 크게 악화시킬 수 있고, 영양염류를 제거하기 위한 혐기, 호기, 무산소 등의 진행과정에서 미생물균이 혐기성 미생물균, 호기성 미생물균, 임의성 미생물균으로 즉시 변환되지 않으므로, 미생물을 이용한 순환변화가 어려워 영양염류의 제거효율 변화 폭이 매우 큰 단점이 있었다.The present invention relates to a batch natural purification method for organic sewage and wastewater, and a device thereof. In the related art, when sedimentation is carried out in one step and discharged, a poorly settled substance is discharged as it is, which can greatly deteriorate the quality of the discharged water. In the process of anaerobic, aerobic, and anaerobic to remove nutrients, microorganisms are not immediately converted to anaerobic, aerobic, or random microorganisms, so it is difficult to circulate using microorganisms. There was a big disadvantage.

본 발명은 이러한 단점을 제거하기 위해 잉여 슬러지 또는 반송 슬러지를 배양조에서 토양성 미생물균군을 우점종화하여 침사지와 분배조, 반응조, 탈수기 저류조에 이송하여 처리공정에서 발생되는 악취 및 방류수에 잔류되어 있는 부유물 등의 문제점을 해결할 수 있었다.In order to eliminate such disadvantages, the present invention predominates the soil microbial group in a culture tank to remove excess sludge or conveyed sludge, and transfers them to the settling basin and distribution tank, the reaction tank, and the dehydrator storage tank. Problems such as floats could be solved.
