통상적으로, 음식물 쓰레기 등의 유기 폐기물은 다량의 동식물성 섬유질, 단백질, 탄수화물, 칼슘, 수분 등을 함유하고 있어, 분해 후 소멸시키지 않고 그대로 매립할 경우 유기 폐기물에서 발생되는 추출물이 지하수 및 상수원으로 유입되어 이들을 오염시키게 된다.In general, organic wastes such as food waste contain a large amount of animal and vegetable fiber, protein, carbohydrates, calcium, water, etc., so that the extracts generated from organic wastes flow into groundwater and water supply when they are landfilled without being destroyed after decomposition. To contaminate them.
그리하여 최근에는 음식물 쓰레기를 포함한 유기 폐기물을 미생물을 이용하여 분해 소멸시키는 방법이 제시되고 있다. 예를들면, 일본국 실용신안공개 제55-8302호, 일본국 실용신안공개 제55-33004호, 일본국 실용신안 공개 제3-34030호, 일본국 실용신안공개 제3-45936호, 일본국 실용신안공개 제4-45589호 및 일본국 실용신안공개 제6-42935호 등에 개시된 "유기성 고형물 폐기물의 발효장치"; 대한민국 실용신안 공개공보 제94-12627호, 실용신안 공개공보 제94-12628호, 실용신안 공개공보 제94-20714호, 실용신안 공개공보 제96-4300호, 실용신안 공고공보 제95-7395호, 실용신안 공고공보 제95-24804호 및 일본국 실용신안공개 제59-33735호, 일본국 실용신안공개 제63-162843호 등에 개시된 "음식물 쓰레기나 유기 폐기물을 비료나 사료화하는 방법이나 장치"; 일본국 특허공개 제8-132008호에 개시된 "유기폐기물의 탄화처리장치"; 일본국 특허공개 제8-132004호, 일본국 특허공개 제8-57458호 및 일본국 특허공개 제8-57459호에 개시된 "음식물을 포함한 쓰레기의 처리장치"가 그것이다.Thus, recently, a method of decomposing and extinguishing organic waste including food waste using microorganisms has been proposed. For example, Japanese Utility Model Publication No. 55-8302, Japanese Utility Model Publication No. 55-33004, Japanese Utility Model Publication No. 3-34030, Japanese Utility Model Publication No. 3-45936, Japan "Fermentation apparatus of organic solid waste" disclosed in Utility Model Publication No. 4-45589 and Japanese Utility Model Publication No. 6-42935; Korea Utility Model Publication No. 94-12627, Utility Model Publication No. 94-12628, Utility Model Publication No. 94-20714, Utility Model Publication No. 96-4300, Utility Model Publication No. 95-7395 "Method and apparatus for fertilizing or feeding food waste or organic waste" disclosed in Utility Model Publication No. 95-24804, Japanese Utility Model Publication No. 59-33735, and Japanese Utility Model Publication No. 63-162843; "Carbonation treatment apparatus of organic waste" disclosed in Japanese Patent Laid-Open No. 8-132008; "A waste disposal apparatus including food" disclosed in Japanese Patent Laid-Open No. 8-132004, Japanese Patent Laid-Open No. 8-57458 and Japanese Patent Laid-Open No. 8-57459.

레스토랑의 조리장에서 배출된 음식물 쓰레기 100㎏을 본 발명 및 종래 실시예에 따른 유기 폐기물 처리 장치에 각각 넣고 24시간동안 처리하여 <표 1>과 같은 결과를 얻었다. <표 1>에서 알 수 있는 바와 같이 본 발명의 유기 폐기물 처리 장치는 종래의 유기 폐기물 처리 장치와 비교하여 최종적으로 배출되는 폐수량도 작을 뿐 아니라, 폐수의 BOD값도 현저히 낮았다.100 kg of the food waste discharged from the restaurant of the restaurant was put into the organic waste treatment apparatus according to the present invention and the conventional example, and treated for 24 hours to obtain a result as shown in <Table 1>. As can be seen from Table 1, the organic waste treatment apparatus of the present invention was not only small in the amount of waste water finally discharged compared to the conventional organic waste treatment apparatus, but also significantly lower in BOD value of the waste water.
(여기서, MLSS는 Mixed Liquor Suspender Solid로서 미생물 농도를 표시한다.)(Here, MLSS is a mixed liquor suspender solid and displays the microbial concentration.)
상술한 바와 같이 본 발명의 실시예에 따른 유기 폐기물 처리 장치는 최종 배출수를 배출함에 있어 내부에 잔존하고 있는 오니를 제거하는 등 재차 정화시켜 배출함으로써, 배출수로 인한 2차 오염을 막아 환경 오염 방지 및 상수원 보호 등에 큰 효과가 있다.As described above, the organic waste treatment apparatus according to the embodiment of the present invention purifies and discharges the sludge remaining inside to discharge the final discharged water, thereby preventing secondary pollution due to the discharged water to prevent environmental pollution and It has a great effect on water supply protection.
또한, 본 발명의 실시예에 따른 유기 폐기물 처리 장치는 장치의 크기나 구조는 컴팩트하게 유지하면서도 배수 정화 기능을 추가로 갖추게 됨으로써 제작 및 설치가 용이한 효과가 있다.In addition, the organic waste treatment apparatus according to the embodiment of the present invention has an effect of facilitating manufacture and installation by additionally equipped with a wastewater purification function while maintaining a compact size or structure of the apparatus.
또한, 본 발명의 실시예에 따른 유기 폐기물 처리 장치는 1차 배출된 물을 냉각수로 재활용함으로써 냉각수 보급 기간이 길어지는 등 관리가 편리한 효과가있다.In addition, the organic waste treatment apparatus according to an embodiment of the present invention has a convenient management effect such that the cooling water supply period is extended by recycling the first discharged water to the cooling water.
