일반적으로 유기물을 발효시켜 퇴비로 사용한 것은 오래 전부터 인류가 사용하여 왔던 방법이다.In general, fermentation of organic matter and composting is a method that has been used by humans for a long time.
이러한 종래의 유기물의 퇴비화는 야적지에 퇴비무덤을 만들어 방치하여 악취가 심하게 나고 하절기에는 해충이 들끓는 단점이 있었으나, 인구밀도가 적은 시대에는 그 다지 큰 문제가 없었다.The composting of the conventional organic matter had a disadvantage that the bad smell odors and the pests swell during the summer season by leaving the compost grave on the yard, but there was not a big problem in the age of low population density.
그러나, 근래와 같이 인구가 증가하고 산업이 발달됨에 따라서, 음식물 쓰레기, 하수슬러지, 축산폐기물, 분뇨 등과 같은 각종 유기성 폐기물의 발생량은 점점 증가하고 있고, 이러한 유기성 폐기물의 처리는 매우 심각한 문제로 대두되고 있다.However, with the recent increase in the population and the development of industry, the generation of various organic wastes such as food waste, sewage sludge, livestock waste, and manure is increasing, and the disposal of such organic wastes is very serious problem. have.

상기 침출수의 인위적인 처리를 위하여 톱밥과 왕겨와 같은 부재료가 다량으로 소요되어 처리비용이 많이 드는 단점 및,Disadvantages in that a large amount of subsidiary materials, such as sawdust and rice husk, are required for the artificial treatment of the leachate and the treatment cost is high.
악취 발생을 근본적으로 제거하지 못하고 특히, 음식물 쓰레기는 염분의 농도가 높아 감량화, 퇴비화하여도 염해 때문에 퇴비로 사용할 수 없는 단점이 있었다.Odor generation is not fundamentally eliminated, and in particular, the food waste has a high salt concentration, so even when reduced or composted, there was a disadvantage that it cannot be used as compost because of salt.
본 발명은 상기와 같은 종래의 유기성 폐기물의 처리방법의 단점을 효과적으로 해소하고자 연구 개발된 것으로서,The present invention has been researched and developed to effectively solve the disadvantages of the conventional method for treating organic waste as described above,

도 1은 본 발명의 공정을 도시한 계통도.1 is a schematic diagram illustrating a process of the present invention.
본 발명의 방법에 의하면, 염해가 없는 퇴비가 제조되는 효과뿐 아니라, 예를 들어 음식물 쓰레기 30ton(함수율 80%)이 발효 감량되어 1.2ton(함수율 50%)으로 줄어들게 됨으로 퇴비로 활용하지 않더라도 감량 효과는 지대하다(감량율 96%).According to the method of the present invention, in addition to the effect that the salt-free compost is produced, for example, 30 tons of food waste (water content of 80%) is reduced to fermentation is reduced to 1.2 tons (water content of 50%), for example, even if not used as a compost reduction effect Is huge (96% reduction).
이하, 본 발명의 유기성 폐기물의 감량화 방법을 구체적으로 실시할 수 있는 바람직한 실시예를 첨부도면 도 1에 의거하여 상세히 설명한다.Hereinafter, a preferred embodiment in which the organic waste reduction method of the present invention can be specifically carried out will be described in detail with reference to the accompanying drawings.
유기성 폐기물을 통상의 파쇄기구를 이용하여 파쇄한다.Organic waste is crushed using a conventional crushing apparatus.
상기 파쇄된 유기성 폐기물을 함수율 조절용 호퍼(Hopper)에 투입하고 씨퇴비와 혼합 교반하여 함수율이 60~65%가 되도록 조절한다.The crushed organic waste is put into a hopper for water content control (Hopper) and mixed with a seed compost to be stirred to adjust the water content to 60 ~ 65%.
상기 함수율이 조절된 유기성 폐기물을 산기관이 장착된 퇴비사에 이송하여 1.5~2m 정도의 높이로 퇴적하여 발효시키게 된다. 이렇게 유기성 폐기물의 발효가 시작되면 온도가 상승하기 시작하여, 1주일 정도에 65~70℃로 온도가 상승하였다가 하강하기 시작한다. 온도가 하강하기 시작하면 페이로다 등으로 상기 퇴적된 퇴비무덤을 교반한 후, 다시 퇴적하여 두면 온도가 다시 상승하였다가 하강하며, 이때 다시 상기와 동일한 방법으로 교반, 퇴적하여 둔다. 이러한 교반, 퇴적을 수회, 바람직하게는 3회 반복하여서 발효과정을 마치게 된다.The organic waste of which the moisture content is controlled is transferred to a compost yarn equipped with an diffuser to be deposited at a height of about 1.5 to 2 m for fermentation. When fermentation of organic waste begins, the temperature starts to rise, and the temperature rises to 65-70 ° C in about a week and then begins to fall. When the temperature starts to fall, the deposited compost tomb is stirred with a payloader or the like, and if it is deposited again, the temperature rises and then falls again. At this time, it is stirred and deposited in the same manner as above. This agitation and deposition are repeated several times, preferably three times, to complete the fermentation process.
상기 발효가 종결된 퇴비를 숙성사에 이송하여 2개월 이상 숙성시켜 완숙 퇴비를 제조하는 과정을 취하게 된다.The fermentation is completed by transferring the compost to the aging company to take a process of producing mature compost by aging for at least two months.
상기 숙성사에 퇴적된 퇴비를 채방식(스크린 설비, 진동타입, 메쉬타입)으로 걸러 못, 유리조각, 비닐 조각 등을 분리 제거하여, 퇴비를 제조하고, 이 완성된 퇴비의 일부는 상기 함수율 조절 단계에 반송하여 함수율 조절 및 악취제거용 씨퇴비로 사용하고, 나머지 잉여분의 숙성퇴비는 포장하여 토양개량제의 퇴비로 활용하게 된다.The compost deposited on the aged sand is filtered by a method (screen equipment, vibration type, mesh type) to separate and remove nails, pieces of glass, and pieces of vinyl, thereby preparing compost, and a part of the completed compost is used to control the moisture content. It is returned to the stage to be used as a compost for water content control and odor removal, and the remaining surplus maturing compost is packaged and used as a compost for soil improving agent.
이때, 상기 함수율 조절 단계에서 발생되는 악취나는 침출 폐액(침출수)을 침출수 처리라인의 조정조에 이송한 후, 폭기조를 거쳐 침전조에서 고액분리하고, 침전조로부터의 침전 오니의 일부를 상기 조정조로 반송하여, 침출수와 혼합 교반하고, 상기 과정을 반복하므로써 침출수중의 유기물의 분해를 유도하게 된다. 이 모든 과정에서 침출수의 악취가 제거된다.At this time, the odorous leachate (leaching water) generated in the water content control step is transferred to the adjusting tank of the leachate treatment line, and then solid-liquid separation from the settling tank through the aeration tank, and part of the sludge from the settling tank is returned to the adjusting tank, Mixing and stirring with the leachate and repeating the above process leads to decomposition of the organics in the leachate. In all this the odor of the leachate is removed.
상기 침전조에서의 고액분리에 의해 생성되는 상등수(활성수)는 방류조로 이송시키고, 이 방류조에 이송된 활성수를 유기성 폐기물의 운반차량과 운반용기의 세척수로 활용하므로써 악취를 제거하고, 세척한 물은 다시 조정조로 반송하여 활성수의 원료로 사용하고, 남은 활성수는 상기 퇴비 제조공정의 퇴비사의 발효단계에 반송하여 퇴비사에 분무하여 수분조절 및 악취제거용으로 사용하는 과정을 취하게 된다.The supernatant water (active water) generated by the solid-liquid separation in the sedimentation tank is transferred to the discharge tank, and the odor is removed and washed by utilizing the active water transferred to the discharge tank as a vehicle for transporting organic waste and washing water for the container. The silver is returned to the adjustment tank to be used as a raw material of the active water, and the remaining active water is returned to the fermentation stage of the composting process of the compost manufacturing process and sprayed on the composting sand to be used for moisture control and odor removal.
이때, 상기 침전조에서 고액분리에 의해 생성되는 침전 오니의 일부를 오니저류조에 이송하여 규산염분이 충진된 반응기(Reactor tower)에 의해 배양한 후, 배양된 오니를 상기 퇴비 제조공정의 함수율 조절단계 및 퇴비사 발효단계에 일정량 반송시키어 퇴비의 원료로 사용하는 반복적인 과정에 의하여 연속적으로 퇴비를 제조하게 된다.At this time, a part of the settling sludge produced by solid-liquid separation in the settling tank is transferred to the sludge storage tank and cultured by a silicate-filled reactor (Reactor tower), and then the cultured sludge is controlled by the moisture content of the compost manufacturing process and the compost sand. The compost is continuously produced by a repetitive process of returning a certain amount to the fermentation step and using it as a raw material of the compost.
이러한 연속적인 과정에 의하여 유기물은 모두 부식물로 처리되면서 침출수는 깨끗한 물로 정화되어, 전량 재활용된다.By this continuous process, the organics are all treated with corrosive materials, and the leachate is purified to clean water and recycled entirely.
특히, 유기성 폐기물(음식물 쓰레기)은 그 속에 함유된 염분이 Na+와 Cl-으로 이온화된 상태에서 킬레이트에 포집되어 Na이온은 부식산 나트륨으로 변하고, Cl이온은 다른 유기물과 화합하여 새로운 물질로 변화되어, 제조되는 퇴비가 염해가 없는 퇴비로 되어 토양개량제로의 활용이 가능하게 된다.In particular, organic wastes (food wastes) are trapped in chelates with the salts in them ionized into Na + and Cl − so that the Na ions turn into sodium humate, and the Cl ions combine with other organic matter to form new substances. As a result, the produced compost becomes salt-free compost, which makes it possible to use as a soil improving agent.
이상에서 상세히 살펴본 바와 같이, 본 발명은 토양, 수계오염 및 대기오염의 주범인 음식물 쓰레기, 축분, 폐수처리장의 슬러지를 효과적으로 감량화하여 환경정화에 기여하고, 생산된 퇴비는 염해가 전혀 없게 되어 토양 개량제로 활용하여 경제성이 확보되며, 막대한 시설의 유기성 폐기물의 매립용지가 필요없게 되어 유기성 폐기물의 처리에 따른 소요비용을 절감하게 된다.As described in detail above, the present invention contributes to the environmental purification by effectively reducing the sludge of the soil, water pollution and air pollution, food waste, animal waste, and sludge in the wastewater treatment plant, and the produced compost is no salt harm so that the soil improver Economical efficiency is secured by using it, and landfills of organic wastes of enormous facilities are not required, thereby reducing the cost of treating organic wastes.
