Description
본 발명은 유기성 오 폐수의 처리를 위해 사용되는 활성오니 접촉담체 및 그 제조방법에 관한 것이다.The present invention relates to an activated sludge contact carrier used for the treatment of organic wastewater and a method for producing the same.
산업용 폐수나 축산폐수 및 생활오수 등과 같은 유기성 오 폐수의 처리는 일반적으로 미생물을 이용한 생물학적 처리에 의존하며, 이 생물학적 처리의 효율을 높이기 위해 미생물제재를 사용하기도 한다.Treatment of organic wastewater, such as industrial wastewater, livestock wastewater and domestic wastewater, generally relies on biological treatment with microorganisms, and microbial agents are also used to increase the efficiency of this biological treatment.
이러한 일반적인 오 폐수의 처리방법은 수중에 함유된 미생물균의 증식에 적당한 조건을 가지는 반응조에서 호기성 미생물이 증식되어 혼탁한 유기물질을 분해하고, 이렇게 반응조를 통해 분해된 유기물질은 침전조에서 고액분리한 후 분리된 상등액인 처리수를 하천으로 방류시키게 된다.In this general wastewater treatment method, aerobic microorganisms grow and decompose turbid organic matter in a reaction tank having conditions suitable for the growth of microorganisms in water. After that, the treated supernatant is discharged to the stream.
그러나 상기와 같은 일반적인 유기성 오 폐수 처리방법은 미생물에 의해 유기물질을 분해, 발효, 산화시키기 위해 최소 6∼8시간의 접촉시간이 요구되며, 또한 일반적인 처리방법보다 효율을 높이기 위해 사용되고 있는 미생물제재를 이용한 처리방법은 다소의 효율은 기대할 수 있으나, 이 또한 생물학적 처리에만 한정될 뿐이다.However, the above general organic wastewater treatment method requires a contact time of at least 6 to 8 hours in order to decompose, ferment and oxidize the organic material by microorganisms, and is also used to improve the efficiency of microorganisms that are being used to improve efficiency than general treatment methods. The treatment method used can be expected to have some efficiency, but this is also limited to biological treatment only.
따라서 종래의 유기성 오 폐수의 처리방법은 생물학적인 처리 과정에서 질산화물 및 황산화물이 비산될 때 발생하는 악취가 대기를 오염시키고, 유입수의 수질변동, 즉 유입수의 오염농도 변화가 심하고 이물질의 함유량이 갑자기 많이 발생하거나, 유입수에 살균제 및 기름과 같은 독성물이 혼입될 경우에는 처리시스템내에 존재한 미생물의 활동을 방해 또는 사멸시켜 유기물의 분해를 어렵게할 뿐만 아니라 활성오니 플록(floc)의 응집력을 저하시키게 됨으로써 분해되지 않은 부유성 물질(SS)이 상등액과 함께 방류되어 하천을 오염시키는 문제점이 있었다.Therefore, in the conventional method of treating organic wastewater, the odor generated when nitrates and sulfur oxides are scattered during biological treatment contaminates the air, and the fluctuation of water quality of the influent, that is, the pollution concentration of the influent is severe, and the content of foreign substances is sudden. In case of high occurrence or incorporation of toxic substances such as fungicides and oils into the influent, it will interfere with or kill the activity of microorganisms present in the treatment system, making it difficult to dissolve organic matters and reduce flocculation of activated sludge flocs. As a result, the undecomposed suspended matter (SS) is discharged together with the supernatant to contaminate the river.
이에 본 발명은 상술한 바와 같은 종래의 제반 결함을 감안하여 이루어진 것으로, 그 목적은 생물학적 분해 뿐만 아니라 활성오니 플록(floc)의 생성 및 활성화를 촉진시켜 미생물의 증식과 생장력을 강화 및 왕성하게 하고, 물리화학적인 반응으로 활성오니의 응집력을 강하고 무겁게 하여 고액분리가 뚜렷하게 이루어지도록 하며, 유기물 분해에 필요한 시간을 단축시킬 수 있는 유기성 오 폐수처리용 활성오니 촉진제 제조방법을 제공함에 있다.Therefore, the present invention has been made in view of the above-mentioned conventional defects, and its object is to promote and generate biological activity as well as to promote the generation and activation of activated sludge flocs, thereby enhancing and vigorizing the growth and growth of microorganisms, The present invention provides a method for preparing activated sludge accelerator for treating organic wastewater, which can make solid-liquid separation distinctly by making the cohesive force of activated sludge strong and heavy by physicochemical reaction, and shorten the time required for decomposition of organic matter.

이하 본 발명 실시예를 상세히 설명한다.Hereinafter, embodiments of the present invention will be described in detail.
본 발명이 적용되는 유기성 오 폐수처리용 활성오니 접촉담체는 황토를 주성분으로 제조되는 것으로, 주지된 바와 같이 황토 한 스픈에는 약 2억마리의 토양성 미생물이 살고있어 다양한 효소들이 순환작용을 일으키는 것으로, 이러한 황토의 성분에는 카탈라아제, 디페놀옥시다아제, 사카라제, 프로테아제 등이 포함되어 있다.The activated sludge contact carrier for organic wastewater treatment to which the present invention is applied is manufactured with ocher as a main component, and as it is known, about 200 million soil microorganisms live in the ocher-spoon which causes various enzymes to circulate. The components of such loess include catalase, diphenol oxidase, saccharase, protease and the like.
상기 카탈라아제는 미생물의 생장을 저해하는 독소를 제거하며, 디페놀옥시다아제는 황산화제 역할을 하며, 유기물을 분해하여 영양을 공급하고, 사카라제는 비료의 요소에 걸맞는 역할을 하여 미생물의 생육에 필요한 영양물질을 공급하며, 또한 프로테아제는 단백질 속의 아니노산을 가수 분해하여 체내의 노폐물을 없애고 부패를 막는 역할을 한다. 특히 상기와 같은 특성을 가지는 황토에는 수질정화에 필요한 미생물의 신진대사를 돕을 이로운 성분을 함유하고 있다.The catalase removes toxins that inhibit the growth of microorganisms, diphenol oxidase acts as a sulfate agent, decomposes organic matter and supplies nutrition, and saccharase plays a role that is suitable for the fertilizer's urea. In addition to supplying nutrients, the protease hydrolyzes the ananoic acid in the protein to remove waste products in the body and prevents corruption. In particular, ocher having the above characteristics contains beneficial components to help metabolism of microorganisms required for water purification.
이러한 황토에 함유된 각종 이로운 효소와 토양성 미생물이 강력한 활성력을 갖는 최적의 황토 설정을 위하여 전국적으로 널리 분포되어 있는 여러 종류의 황토를 수집하여, 수용액을 만들어 침전액 및 상등수를 비교하였고<실험 1>, 여러종류의 황토를 생물학적 처리효과 실험<실험 2>하여 가장 적합한 황토를 선정하였다. 그 실험 결과는 다음과 같다.In order to establish the optimum loess with various active enzymes and soil microorganisms contained in such loess, various types of loess which are widely distributed throughout the country were collected, aqueous solutions were prepared, and the precipitates and the supernatant were compared. 1>, experiments on biological treatment effect of various types of ocher <Experiment 2> to select the most suitable ocher. The experimental results are as follows.

Through this process, natural sedimentation results in different characteristics of the sediment and the supernatant for each sample. In this way, the degree of solid-liquid separation is confirmed and the pH of each supernatant is checked. As a result, the physicochemical properties of the supernatant with the clearest liquid separation were from pH 4.5 to 6, the color of ocher was red yellow, the specific surface area was 27.2㎡ / g, and the chemical composition was shown in the table below.
