생물활성수(ＢＭＷ) 공법에 의한 축산폐수의 효율적 처리방법 및 그 장치{A Method and Apparatus for treatment of livestock waste water using Bacteria Mineral Water process}A method and apparatus for efficiently treating livestock wastewater by biologically active water ({MＷ} method) {A Method and Apparatus for treatment of livestock waste water using Bacteria Mineral Water process}

본 발명은 축산폐수를 처리하는 방법 및 그 장치에 관한 것이며, 특히 액비화가 어려운 액상의 축산분뇨인 축산폐수를 생물활성수(Bacteria Mineral Water; 이하에서는 ‘BMW’로 약칭합니다) 공법을 이용하여 생물학적 및 화학적 처리공정에 의해 효과적으로 처리하는 방법 및 그 장치에 관한 것이다.The present invention relates to a method and apparatus for treating livestock wastewater, and in particular, livestock wastewater, which is a liquid livestock manure, which is difficult to liquefy, is biologically prepared using a bioactive water (Bacteria Mineral Water; hereinafter abbreviated as 'BMW') method. And a method and an apparatus for effective treatment by a chemical treatment process.

축산폐기물로부터 고ㆍ액 분리된 액상의 축산폐수는 질소 및 인과 같은 영양염류가 다량 함유된 고농도의 유기성 폐수이므로 축산폐수가 하천으로 유입될 경우 영양염류에 의한 부영양화 등으로 히천의 수질에 심각한 오염을 초래하지만, 분뇨 등 고형의 축산폐기물은 하수 등에 비하여 난분해성으로 처리효율이 대체적으로 낮다. The liquid livestock wastewater, which is separated from the livestock waste solids and liquids, is a high concentration of organic wastewater containing nutrients such as nitrogen and phosphorus. Therefore, when livestock wastewater enters the stream, it can cause serious pollution to the water quality of the river due to eutrophication by nutrients. However, solid livestock waste, such as manure, is generally low in treatment efficiency due to poor degradability compared to sewage.

축산폐수 등 고농도의 유기성 폐액의 정화 및 처리방법으로는 활성오니법을 비롯한 장기폭기법, 접촉산화법, 살수여상법 및 이들의 조합에 의한 처리방법 등이 있으나, 상기한 방법들은 호기성 미생물균을 증식 배양시켜 상기 미생물이 유기질을 분해시키는 처리방법으로서, 이러한 종래의 방법들은 주로 호기성 미생물에 의한 폐수정화기술로 폐수의 미생물 분해를 위해 호기성 미생물의 배양 증식에 따른 시간이 많이 소요는 단점이 있으므로 국내 공개특허공보 공개번호 특2003-0026950호에서는 상기 선행기술을 개선점으로 하수처리장의 잉여슬러지를 이용하여 축산폐수를 처리하는 방법 및 장치를 개시하고 있다.As a method of purifying and treating organic waste liquid of high concentration such as livestock wastewater, there are long-term aeration method including activated sludge method, catalytic oxidation method, water treatment method, and a combination thereof, but the above methods multiply aerobic microorganisms. As a treatment method for culturing the microorganisms to decompose organic matters, these conventional methods are mainly wastewater purification techniques by aerobic microorganisms, so it takes a long time due to the growth of aerobic microorganisms for microbial decomposition of wastewater. Patent Publication No. 2003-0026950 discloses a method and an apparatus for treating livestock wastewater using surplus sludge in a sewage treatment plant.

또한 일본특허공보 특허번호 제2504364호는 활성부식물질에 의한 축산폐수 처리기술인 BMW(Bacteria Mineral Water)공법으로 축산폐수를 처리하는 축산폐기물 처리방법을 개시하고 있으나 대량의 공기주입에 따른 다수의 폭기공정이 필요하고, 축산폐수의 처리를 위한 기간이 오래 소요되는 문제점이 있으며, 또 국내 등록특허공보 등록번호 10-0988556호는 축산폐수를 암석 및 토양미생물로 처리하여 생물활성수(BMW ; Bacteria Mineral Water)를 생산하는 축산분뇨 자원화시스템을 개시하고 있으나 축산폐수의 정화를 위한 목적보다는 병충해 및 냉해 방지, 발아 촉진 및 수확량 증대, 토질 개선 및 지력 향상, 사료 효율 증대, 가축 건강 증진, 고품질 퇴비 생산, 악취 및 파리 발생 억제 등에 유용한 생물활성수(Bacteria Mineral Water)의 효율적인 생산에 중점을 둔 기술이다.In addition, Japanese Patent Publication No. 2504364 discloses a method for treating livestock waste by treating livestock wastewater with BMW (Bacteria Mineral Water), a technology for treating livestock wastewater by active corrosive substances, but a large number of aeration processes resulting from a large amount of air injection. There is a problem that takes a long time for the treatment of livestock wastewater, and the Korean Patent Publication No. 10-0988556 is a biologically active water (BMW; Bacteria Mineral Water) by treating livestock wastewater with rocks and soil microorganisms ), But also to produce livestock waste manure resources system, but to prevent pests and cold damage, promote germination and increase yield, improve soil quality and improve intellect, increase feed efficiency, improve livestock health, produce high quality compost, odor rather than purify livestock wastewater. And a technique focused on efficient production of Bacteria Mineral Water, which is useful for suppressing flies.

본 발명은 축산폐수의 정화에 따른 문제점을 해결하여 축산폐수처리 기술분야에서 고ㆍ액 분리한 난분해성으로 액비화가 어려운 액상의 축산폐수를 생물활성수(Bacteria Mineral Water) 공법에 의한 처리공정과 활성슬러지 처리공정 및 화학적 처리공정의 효율적인 조합에 의해 축산폐수를 방류수 수질의 기준치 이하로 정화함으로써 본 발명을 완성하였다.    The present invention is to solve the problems caused by the purification of livestock wastewater by treating the livestock wastewater in difficult to liquid liquefaction with solid and liquid separation in the livestock wastewater treatment technology by the biologically active water (Bacteria Mineral Water) process The present invention has been completed by purifying livestock wastewater to below the standard value of effluent water by an efficient combination of a sludge treatment process and a chemical treatment process.

본 발명은 축산폐수로부터 고ㆍ액 분리한 난분해성의 액비화가 어려운 액상의 축산분뇨인 축산폐수를 생물활성수(Bacteria Mineral Water) 공법에 의한 생물학적 처리, 화학적 처리인 팬톤산화반응 및 물리적 처리인 활성탄 흡착에 의해 효과적으로 처리하는 방법 및 그 장치를 제공하는데 목적이 있다.   The present invention is a biological treatment, a biological treatment by the Bacteria Mineral Water method, a biotreatment of livestock manure, which is difficult to liquid-decompose liquid solidified from solid and liquid separation from livestock wastewater, and a chemical treatment such as pantone oxidation and physical treatment of activated carbon. It is an object of the present invention to provide a method and an apparatus for effectively treating by adsorption.

본 발명에 따른 생물활성수(Bacteria Mineral Water)공법에 의한 축산폐수의 효율적 처리방법 및 그 장치는 활성미생물배양조에서 부식화 미생물 배양체로부터 배양된 부식화 미생물을 생물반응조에 공급하여 부식화 반응 및 활성슬러지에 의한 원수의 생물학적 분해반응 후, 탈질공정, 화학적 산화공정을 거쳐 협잡물이 제거된 액상의 축산폐수인 원수를 완전하게 정화시켜 방류하는 것으로 이루어진다.Efficient treatment method and apparatus for livestock wastewater by the Bacteria Mineral Water method according to the present invention is to supply the corrosive reaction microorganism cultured from the corrosive microbial culture in the active microbial culture tank to the bioreactor and After biological decomposition of raw water by activated sludge, the raw water, which is a liquid livestock wastewater from which contaminants are removed through denitrification and chemical oxidation, is completely purified and discharged.

생물활성수(Bacteria Mineral Water) 공법(이하에서는 ‘BMW 공법’으로 정의합니다)에 의한 일반적인 처리기술은 축산폐기물인 동식물의 유해나 배설물 등으로 대표되는 유기물이 토양에서 부식화되는 원리 즉 토양으로 유입된 유기물이 토양미생물에 의해 분해되는 원리를 이용하는 것이다.    The general treatment technology by the Bacteria Mineral Water process (hereinafter referred to as the 'BMW process') is the principle that organic matters represented by the harmful or excreta of animal and animal wastes, which are livestock waste, are introduced into the soil. This is to use the principle that organic matter is decomposed by soil microorganisms.

상기 토양 미생물군 내에는 주로 호기성 미생물과 통성 혐기성 미생물이 공존하며, 이중에서도 통성혐기성 미생물이 80% 이상 존재한다. 이들의 대사회로는 이중성을 구비하는데, 유리산소의 농도가 2ppm 이상 존재 시 대사회로가 있고, 두 번째 기능은 유리산소 농도가 낮거나 없는 조건하에서 기능을 하는 대사회로가 있다. 물질면에서 보면 전자에 의해 생성한 대사물질에는 페놀(phenol) 또는 phenol 노출기가 있는 화합물이 함유되어 있으며, 이때 작용하는 미생물은 통성혐기성 세균인 방선균, Bacillus 속 등의 미생물이 주체가 되며, 토양에 유입된 유기물은 이들의 미생물에 의해 분해된다. 이 과정을 부식화과정이라 하며, 이와 같은 유기물의 부식화(humification)는 토양 미생물군 (Bacillus, 방선균과 같은 통성혐기성 미생물)의 대사기능과 대사기능의 유도조정에 의해 큰 역할을 하는 규산염이 존재할 때 혐기적 조건하에서 방향족 구성물질이 생성되어 고분자화 하여 최종적으로 토양에 안정된 물질로 부식이 되면서 정화가 된다.     In the soil microbial group, mainly aerobic and anaerobic microorganisms coexist, and among these, at least 80% of anaerobic microorganisms are present. These metabolic circuits have a duality, there is a metabolic circuit when the concentration of free oxygen is more than 2ppm, and the second function is a metabolic circuit that functions under low or no free oxygen concentration. In terms of materials, the metabolites produced by the former contain phenol or compounds with exposed phenol, and the microorganisms acting are mainly microorganisms such as actinomycetes and Bacillus genus. The introduced organic matter is decomposed by their microorganisms. This process is called the corrosive process, and the humification of such organic matters has a silicate that plays a big role by the induction and regulation of metabolic and metabolic functions of soil microorganisms (Bacillus, fascicular anaerobes such as actinomycetes). Under anaerobic conditions, aromatic constituents are formed, polymerized, and finally cleaned and corroded to a stable material in the soil.

When the aeration is carried out, Bacillus bacteria, which have an excellent ability to remove nitrogen from the anaerobic microorganisms latent in activated corrosive soil pellets, are cultured as dominant species, and the residence time is preferably about 1 day.

상기 본 발명에 따른 상기 생물반응조(4)는 유량조정조(2)로부터 유입되는 원수를 생물학적으로 처리하는 반응조로서 생물반응조(4)에서의 원수의 정화는 활성슬러지(반송슬러지)에 의한 생물학적 반응 및 유기물의 토양미생물에 의한 부식화반응 즉 활성미생물 배양조(4)로부터 공급되는 부식화 미생물로부터 유도되는 부식화 반응에 의해 원수 중의 유기물은 부식전구물질인 고분자 물질로 되면서 물에 불용성의 물질로 전환되어 1차 침전조로 이송되는 것으로 이루어진다.    The bioreactor 4 according to the present invention is a reactor for biologically treating the raw water introduced from the flow regulating tank 2, and the purification of the raw water in the bioreactor 4 is carried out by biological reaction by activated sludge (transfer sludge) and Corrosion reaction by organic microorganisms, ie, corrosion reactions derived from the corrosive microorganisms supplied from the active microorganism culture tank 4, the organic matter in the raw water is converted into an insoluble substance in water while becoming a polymer material as a corrosion precursor. It consists of being transported to the primary sedimentation tank.

Decomposition and the conversion of nitrogen to ammonium nitrogen (NH 3 -N), nitrite nitrogen (NO 2 -N) and nitrogen nitrate (NO 3 -N) through the process of decomposing and corrosive to anaerobic microorganisms such as Bacillus As it proceeds, the phosphorus compound causes most of the mineral components eluted from the activated siliceous rocks in the active microbial culture step to recombine with the chelate complexes produced as metabolites in the bioreactor, and most of them are removed.
