Abstract
현재 돼지의 분뇨처리 방법은 액비 형태로 처리 및 농경지에 방류 가능한 BOD,COD,무취 등의 정부의 처리기준에 맞게 정제된 방류수(퇴비기능)를 토양에 방출하는 형태이고,
돼지의 똥,오줌,급수장치를 이용 돼지가 취수 시에 낙하되는 물을 모아둔 것을 일차로 고형물을 걸러내고 고형물이 대부분 제거된 오수를 해수담수화 장비에 공급하여 담수생산 및 담수 생산 시에 발생되는 잉여 응축수( 해수의 경우 고염도 염수에 해당 되는 형태)로 구분 하여 담수화 하는 방법을 이용한 것으로 이 과정에서 고열,저기압처리등의 사유로 미생물이 소멸가능성이 농후하다, 이 응축 오수에 미생물을를 투입하여서 폭기 등의 처리를 병행하여 고농도 액비화 하는 것이다At present, the method of disposal of swine manure discharges discharged purified water (compost function) to the soil according to government processing standards such as BOD, COD, odorless which can be treated in the form of liquid and discharged to farmland.
It is the first time that pigs collect the water that falls down when the pigs take the water by using the pig's poo, piss, watering device, and it supplies the seawater to the seawater desalination equipment, In this process, microbes are likely to disappear due to high temperature, low pressure treatment, etc., and the microbes are introduced into the condensed water. Aeration and the like are carried out in parallel to carry out high concentration liquefaction

해수담수화 기술을 활용하여 돼지 배설물 처리 및 고농도 액비 생산 방법Treatment of pig excrement and production of high concentration liquid using seawater desalination technology
[해결하고자 하는 과제][Problem to be solved]
한국은 과도한 돼지 사육으로 현재는 돈분의 배출이 과다한 상태이며, 축산 농가는 돼지의 똥.오줌,돼지급수시 흘린 물을 모아서 액비로 제조하기 위하여 상당한 기일이(정부권장 6개월) 요구됨 액비 제조회사는 상당한 금액을 받으면서 이를 수거하여 액비로 제조하나 하절기등에는 수요처가 많지 아니하여 돼지 축산농가의 가장 큰 애로사항이 분뇨의 처리임. 한정된 분뇨의 저장 시설에 하절기 방류처를 확보 못한 처리 업체의 처리 지연으로 매일 발생되는 분뇨의 과다로 저장 용양 초과로 돈분이 넘쳐서 농민이 억울하게 형사 처벌되는 사례도 허다함. 현재 대한 민국은 돼지 분뇨의 처리 수량 절감이 시급한 상태임.Korea is in need of a considerable time (6 months recommended by the government) to collect the puddle, urine, and water poured from the pigs and make them into the pot. Is a large amount of money to be collected and collected as liquid fertilizer, but in the summer season, there are not many consumers, so the biggest difficulty of pig farming farmers is the treatment of manure. There is also a case where farmers are punished unfairly due to overfishing due to excessive storage of manure caused by delays in processing facilities that have not secured a summer discharge site in a limited manure storage facility. Currently, the Republic of Korea is in a state of urgent need to reduce the volume of processed pig manure.
돼지 분뇨를 일차로 고형분을 걸러서 건조하고 해수담수화 기술을 활용하여 담수 생산 및 고농도 액비의 원료로 사용하는 것으로 처리업체에 발주하는 처리 수량을 1/5이하로 감소하게 한다.Pig manure is firstly filtered through solid matter, dried and used as seawater desalination technology for freshwater production and high concentration liquid fertilizer to reduce the amount of processed water ordered to the processing company to less than 1/5.
즉 축사의 자체 담수화로 방류되는 수량만큼 처리의뢰 분뇨의 수량이 급격히 감소 하게 된다.In other words, the quantity of the manure to be treated is sharply reduced as much as the quantity of the manure discharged by self-desalination of the housing.
이 때 담수화과정에서 고열, 증산 용량 증가 목적의 저기압처리등의 사유로 액비로 발효화 하기 위한 미생물이 소멸 혹은 감소의 우려가 있는 관계로 적정 미생물 등을 첨가 한다In this case, due to the high temperature in the desalination process, low pressure treatment for the purpose of increasing the evaporation capacity, etc., there is a possibility that the microorganisms to be fermented by the liquid fermentation may disappear or decrease, and appropriate microorganisms are added
돼지 축산 농가의 가장 큰 고민인 분뇨 처리 문제를 현장에서 담수화 처리로 처리 의뢰 용량의 급격한 감소로 농가의 획기적인 처리비용 절감 및 농업 용수 확보 용이, 악취에 시달리는 인근 주민 민원 해소, 고형분의 퇴비화로 농업 생산성 증대.Treatment of manure disposal, which is the biggest concern of pig farming farmers, by desalination treatment in the field, drastically reduced the requesting capacity of the farm to reduce the disposal cost of the farm and easy to secure farming water, solve complaints of nearby residents suffering from bad odor, increase.
돼지분뇨를 1차로 고형분을 걸러서 퇴비화 하기 쉬운 형태로 제조하고, 해수 담수화 기술 활용 돼지 배설물 처리 및 고농도 액비원료의 생산 방법Pig manure is firstly prepared by filtering solids and making it easy to compost, processing seawater desalination technology, processing pig excrement and producing high-concentration liquid raw materials
해수로 부터 염분 및 기타 화학물질을 제거하여 담수를 생산하기 위하여 다단 플래쉬법, 다중효용법, 증기압축법과 같은 증발법과 막을 이용한 역삼투압법, 전기를 이용한 전기투석법, 및 냉동법, 이온교환수지법 등의 공정 및 보다 적은 에너지로 담수를 생산하는 순도가 높고 단위 생산수당 에너지 소비량이 적고 스케일 행성을 방지하기 위해 기압을 내려 끓는점을 낮춘 증발법, 역삼투압 법의 취수, 응집·여과 등의 전 처리, 고압펌프와 응축수에서 에너지를 회수하여 사용할 수 있게 하는 에너지회수장치를 갖춘 역삼투시스템, 등의 방법으로 기술력을 확보 하고 있는 해수 담수화 기술을 활용하기 위한 해수유입과 유사한 상태로 전환을 위하여, 1차로 고형분이 여과된 돼지 분뇨 오수를 해수 담수화 방법으로 고농도 응축오수와 자유롭게 배출 가능한 담수를 구분 하여 외부처리업체에게 의뢰하는 분뇨의 수량을 획기적으로 저감 시키는 것이다. 이 때 액상화된 고형분은 이송시키면서 열품건조 등의 방법으로 건조하여 퇴비자원으로 활용한다.In order to produce fresh water by removing salt and other chemicals from seawater, it is necessary to use evaporation method such as multi-stage flash method, multiple utility method, vapor compression method, reverse osmosis method using membranes, electrodialysis method using electricity, Etc., the purity to produce fresh water with less energy, the energy consumption per unit production is low, the evaporation method which lowers the boiling point by lowering the pressure to prevent the scale planet, the pretreatment such as the withdrawal of the reverse osmosis method, coagulation and filtration , A reverse osmosis system equipped with an energy recovery device that can recover energy from a high-pressure pump and condensate, etc. In order to switch to a state similar to seawater inflow to utilize seawater desalination technology, Pig manure wastewater filtered by solid water can be freely discharged with high concentration of wastewater by seawater desalination method One is to drastically reduce the quantity of manure that is separated from the fresh water and referred to an external processing company. At this time, the liquefied solids are dried and transferred to a composting resource.
이때 응축수는 액비화를 위하여 담수화과정에서 소멸,감소의 우려가 있는 미생물을 투입 및 포기등의 처리로 액비화 한다.At this time, the condensed water is liquefied by the treatment such as the addition and the abandonment of the microorganisms which are likely to disappear or decrease in the desalination process for the liquefaction.
[실시예][Example]
돼지 2000두를 사육하는 축산 농가에서 1두당 0.005m3(5리터)씩 매일 배출 되는 총량 10,000리터를(10m3 비중 1로 추정 10톤) 정부 기준 6개월간 발효를 시키려면 18만 리터의 저장 용량이 필요하여 여분 포함하여 200m3(통칭 200톤)의 저장 면적이 필요하나,공간의 부족으로 조기 방출을 위하여 위하여 미생물 투입,폭기의 방법으로 호기성 미생물을 활발하게 작용하게하여서 25일 단위로 액비업체 혹은 방류 업체에게 25톤을 톤당 25.000원씩에 방출하였다.A total of 10,000 liters (10,000 tons per day) of 0.005 m 3 (5 liters) per 1 livestock farming house with 2000 pigs is estimated to be 10 tons per 10 m 3. this in need, including extra 200m 3 one need a storage area (common name 200 tons), hayeoseo actively acts by aerobic microorganisms in the microorganism is turned on, the method of aeration, in order to early release due to the lack of space for manure areas 25 days Or 25 tons / ton to the discharge company.
하절기등의 시기에 이 분뇨를 받아 줄 농가가 부족한 상태에서는 저장 요량의 부족으로 분뇨탱크가 넘쳐서 형사처벌을 받다가, 1차로 고형분의 퇴비화 2차 담수화 설비로 약 15%만 처리하게 되어서 기존 시설인 저장량 20만리터를 (20톤) 6개월에 1회 처리의 방법으로 초봄.가을등의 시기에 요구량에 많은 시기에 배출을 하는 방법으로 전환하다.In the case of lack of farmhouse to receive this manure during the summer season, the manure tank is overcrowded due to the shortage of storage capacity, and then it is subject to criminal penalties, and it is treated only about 15% by the secondary composting desalination plant of solid content, It is converted into the method of discharging at the time of demand at the time such as early spring and autumn by the method of processing 20,000 tons (20 tons) once every six months.
축사에서 매일 방출되는 분뇨의 1차 고형분 처리는 스크루 이송 방법 및 열풍 건조로 수분 함유량 15%이하로 건조하여서 고형 퇴비재료로 생산하고 이송 및 제조 경로에 고압 방지를 위한 맥도날 위에 탈취필터 이중 부착 방식으로 냄새를 제거하여 공기를 방출하고,담수화 되어서 정부 배출 기준을 충족한 상태로 농업 용수로 바로 방류하고. 잉여 응축 오수는 저장조에 다시 들어가게하고 미생물 투입,포기의 방법으로 호기성 발효를 유도하여 무취,BOD,COD 등의 기준 충족 혹은 처리 업체를 통하여 6개월 1회 방출 한다.The primary solids treatment of manure that is released daily from the house is by screw conveying method and hot air drying to produce moisture content of less than 15% to produce solid compost material and deodorization filter To remove the odor to release air, to desalinate and discharge to agricultural water in a state satisfying government emission standards. Surplus condensed sewage enters the storage tank again and induces aerobic fermentation by microbial input and abandonment method, and it releases it once every six months through satisfying standards such as odorless, BOD, COD, or the treatment company.
