본 발명에서는 축산폐수, 분뇨, 매립지 침출수, 식품가공공장 배출폐수, 도축장폐수, 수산물가공공장 배출폐수, 음식물쓰레기 침출수 및 탈수여액과 같은 고농도유기성폐수를 경제적이면서 효율적으로 고도처리를 하기 위해서 토양의 유기물질을 안정된 부식물질로 전환하는 부식화미생물 및 이들 미생물과 상호공생관계에 있는 미생물의 생육환경조건이 최적이 되면서 부식화반응이 활발히 일어날 수 있는 최적의 환경조건을 조성하여 활성화되게 배양된 이들의 미생물에 의해 폐수중 유기오염물질은 물론이고, 질소, 인, 악취유발물질 등을 물에 불용성이면서 비휘발성의 부식전구물질로 전환하여 침전 제거한 다음에 산화, 응집처리 후에 침전 또는 가압부상처리에 의해서 탈색 및 미 제거된 오염물질을 고도처리를 하는 공정으로, 유기물질을 안정적이면서 효율적으로 부식물질을 생성하는 부식화반응 메카니쥼(Mechanisms)과 부식화미생물 및 이들 미생물과 상호공생관계에 있는 미생물의 종류와 특성을 보면 다음과 같다.In the present invention, in order to economically and efficiently process high concentration organic wastewater such as livestock wastewater, manure, landfill leachate, food processing plant wastewater, slaughterhouse wastewater, aquatic product plant wastewater, food waste leachate and dehydration filtrate, Corrosive microorganisms converting substances into stable corrosive materials and microorganisms that have mutual symbiosis with these microorganisms are optimized, and the optimum environmental conditions for the active corrosive reactions are created and their cultured to be activated. By microorganisms, not only organic pollutants in wastewater but also nitrogen, phosphorus and odor-causing substances are converted into insoluble and non-volatile corrosion precursors in water and precipitated and then oxidized and flocculated, followed by precipitation or pressure injury treatment. It is a process to highly treat decolorized and unremoved pollutants. As never look at the corrosion reaction mechanical nijyum (Mechanisms) and corrosion Chemistry microorganisms and the type and nature of the microorganisms in these microorganisms and the mutual symbiotic relationship to efficiently generate corrosive materials as follows.

토양에 유기물질이 투입되면 소랑셀루로섬(Sorangium cellulosum), 악티노마이세스 그로비오포러스 로시어스(Actinomyces globioporus roseus)와 같은 방선균, 아스퍼길러스 니거(Aspergillus niger), 페니실륨종(Penicillium Sp.)과 같은 곰팡이류, 세파로스포륨 고르도니(Cephalosporium gordoni), 바실루스 마이코이데스(Bacillus mycoides), 바실루스 루테어스(Bacillus luteus)와 같은 균류등은 녹말, 당류, 단순 단백질과 같이 분해가 용이한 물질을 섭취하여 CO2, H2O와 같은 간단한 무기화합물로 분해하면서 대사산물로 폴리페놀(Polyphenol)성 화합물을 배설한다.When organic substances are put into the soil, Actinomyces such as Sorangium cellulosum, Actinomyces globioporus roseus, Fungi such as Aspergillus niger, Penicillium sp. Fungi such as cephalosporium gordoni, Bacillus mycoides, and Bacillus luteus consume CO 2 , H 2 by ingesting easily degradable substances such as starch, sugars, and simple proteins. Decompose into simple inorganic compounds such as O and excrete polyphenolic compounds as metabolites.

그리고, 폴리페놀성화합물은 공기중에서 산소와 부식물질중에 함유된 산화효소(Polyphenoloxidase)의 촉매작용에 의해서 퀴논(Quinone)화합물로 산화되면서 과산화수소(H2O2)를 생성한다.In addition, the polyphenolic compound generates hydrogen peroxide (H 2 O 2 ) as it is oxidized to a quinone compound by the catalytic action of oxygen and corrosive oxidase (Polyphenoloxidase).

과산화수소(H2O2)는 토양중에 존재하는 제일철염(FeSO4)과 같은 금속염과 반응하여 푸리 하이드록실기(Free Hydroxyl Radical ; OHㆍ)를 생성한다.Hydrogen peroxide (H 2 O 2 ) reacts with metal salts such as ferrous salt (FeSO 4 ) present in the soil to form Free Hydroxyl Radical (OH ·).

푸리 하이드록실기는 부식화반응 중간에 생성되는 풀브산(Fulvic acid)과 같은 유기산(Organic acid)과 반응하여 과산화물질을 생성한 다음에 산화효소(Oxidase)를 생성한다.Puri hydroxyl groups react with organic acids such as Fulvic acid, which are formed during the corrosive reaction, to produce peroxides and then to produce oxidases.

산화효소는 폴리페놀화합물을 공기 중에서 퀴논화합물로 산화하는데 촉매적인 역할을 한다.Oxidases catalyze the oxidation of polyphenolic compounds to quinone compounds in the air.

퀴논화합물은 미생물에 의해서 분해가 어려운 셀루로스(Cellulose), 탄닌(Tannin), 리그닌(Lignin) 등과 중ㆍ축합반응을 하여 물에 불용성이면서 비휘발성의 안정된 거대 고분자물질인 부식물질이 생성된다.The quinone compound undergoes a polycondensation reaction with cellulose, tannin, and lignin, which are difficult to decompose by microorganisms, to produce a corrosive substance which is insoluble in water and is a non-volatile, stable macromolecular substance.

악취발생물질인 암모니아(NH3), 유화수소(H2S), 메르캅탄(Mercaptan), 휘발성 아민과 같은 물질은 부식물질에 부동화(Immobilization)되므로써 악취발생이 저감된다.Odor-producing substances such as ammonia (NH 3 ), hydrogen sulfide (H 2 S), mercaptan, and volatile amines are immobilized to corrosive substances to reduce odor generation.

또한, 부식전구물질은 킬레이트(Chelate)성 물질로서 토양중 미네랄성분과 착화합물을 형성하여 동ㆍ식물에 미네랄 공급이 용이하게 하는 기능을 가지고 있다.In addition, the corrosion precursor material is a chelate material and has a function of facilitating mineral supply to animals and plants by forming complex compounds with minerals in the soil.

특이한 사항은 부식화반응에 의한 폐수처리의 경우에는 질소화합물이 폴리펩타이드(Polypeptide), 아미노산의 형태로 부식물질에 부동화되어 잉여오니로 제거되므로서 호기성, 혐기성의 조작이 없이도 질소화합물이 고도로 처리될 수 있다.In particular, in the case of wastewater treatment by the corrosion reaction, nitrogen compounds are immobilized to corrosive substances in the form of polypeptides and amino acids and removed as surplus sludge so that nitrogen compounds can be treated highly without aerobic and anaerobic manipulation. Can be.

그리고, 부식화미생물과 상호공생관계에 있는 미생물중에는 생물인광석(Bio-phosphate)이라고도 하는 악시네토박터속(Acinetobacter Sp.) 등이 우점적으로 생육하기 때문에 폐수중 인 성분은 거의 완벽하게 제거된다.Also, among the microorganisms that are mutually symbiotic with the corrosive microorganisms, Acinetobacter Sp., Also known as bio-phosphate, predominantly grows, so that the phosphorus component in the wastewater is almost completely removed. .

부식화반응에 의한 폐수중 유기오염물질의 처리효율을 향상하기 위해서는 다음과 같은 환경조건을 조성해 주어야 한다.In order to improve the treatment efficiency of organic pollutants in wastewater by corrosion reaction, the following environmental conditions should be established.

1) 부식화미생물 및 이들 미생물과 상호공생관계에 있는 미생물은 세포막이나 세포핵 등에 미네랄 함량이 높기 때문에 미네랄 공급이 충분하여야만 활발한 대사활동을 하므로 시스템(System)내에 충분한 미네랄을 공급하여야 한다.1) Corrosive microorganisms and microorganisms that have mutual symbiosis with these microorganisms have high mineral content in cell membranes and cell nuclei, so they must be supplied with sufficient minerals for active metabolic activity. Therefore, sufficient minerals must be supplied in the system.

2) 활발한 부식화반응에 의해서 부식물질이 생성되기 위해서는 산화효소의 공급이 원활하여야 하며, 부식화미생물 및 이들 미생물과 상호공생관계에 있는 미생물의 대사활동이 활발하여야 한다.2) In order for corrosives to be produced by active corrosive reactions, the supply of oxidase must be smooth, and the metabolic activity of corrosive microorganisms and microorganisms that have mutual symbiosis with these microorganisms must be active.

이들 미생물은 산화환원전위(ORP) 값이 +250∼+350mV인 산화적 분위기에서 활발한 대사활동을 하면서 부식화반응이 촉진되기 때문에 산화효소의 공급과 호기성 분위기가 되어야 한다.These microorganisms have to be supplied with oxidase and aerobic atmosphere because the corrosive reaction is promoted by active metabolic activity in an oxidative atmosphere with an ORP value of +250 to + 350mV.

3) 적정 pH의 조건은 6전후의 약산성에서 부식화미생물의 생육이 활발하므로 pH는 5.5∼6.5 정도로 유지하는 것이 좋다.3) Since the growth of corrosive microorganism is active at weak acidity around 6, the pH should be maintained at 5.5 ~ 6.5.

4) 온도는 중온성미생물로 25∼35℃에서 부식화미생물의 생육이 활발하나 저온이나 고온에 대한 내성은 일반활성오니에서 활동하는 미생물에 비해서 내성이 강하다.4) The temperature is mesophilic microorganisms, and the growth of corrosive microorganisms is active at 25 ~ 35 ℃, but the resistance to low temperature and high temperature is stronger than that of microorganisms in general activated sludge.

이상과 같은 조건을 감안하여 본 발명에서는 폐수중 유기오염물질이 생물학적 부식화반응에 의해서 경제적이면서 효율적으로 고도처리를 할 수 있는 처리공정을 개발하였는데 도면을 중심으로 설명하면 다음과 같다.In view of the above conditions, the present invention has developed a treatment process capable of economically and efficiently highly treating organic pollutants in wastewater by biological corrosive reactions.

고농도유기성폐수의 경우에는 유입폐수중 대형고형물은 조목스크린(1)에서 제거하고, 모래와 같이 비중이 무거운 이물질은 침사지(2)에서 침전되면 침사지 스크랩퍼(3)에 의해서 제거된 다음에 저류조(4)로 보낸다.In the case of highly concentrated organic wastewater, large solids in the inflow wastewater are removed from the crude wood screen (1), and foreign substances with heavy gravity such as sand are removed by the sedimentation scraper (3) when settled in the sedimentation basin (2), 4) to send.

폐수중 SS(Suspended solid)분은 진동세목스크린(7)에 의해서 제거하거나 축산폐수와 같이 유기성 SS 성분이 다량 함유되어 있는 경우에는 탈수기(6)에 의해서 탈수 처리후 여액을 집수조(8)로 보낸다.SS (Suspended solid) in the waste water is removed by vibrating fine screen (7), or in the case of containing large amount of organic SS components such as livestock waste water, dehydrator (6) sends the filtrate to the sump (8) after dehydration treatment. .
