Description

분뇨 및 축산폐수의 무방류 처리방법{Treatment method of waste water and excrementitious matter}Treatment method of waste water and excrementitious matter

본 발명은 분뇨 및 축산폐수의 무방류 처리방법에 관한 것으로서, 보다 상세하게는 분뇨 및 축산폐수를 발효시켜 고형분은 퇴비로 액상분은 액비로 재활용하는 새로운 구성의 분뇨 및 축산폐수의 무방류 처리방법에 관한 것이다.The present invention relates to a method for non-discharge treatment of manure and livestock waste, and more particularly, to a method for non-discharge treatment of manure and livestock waste in a new configuration in which solid waste is composted to ferment manure and livestock wastewater, and liquid content is converted into liquid fertilizer. will be.

분뇨나 축산폐수는 그대로 방류하면 심각한 환경오염을 유발하기 때문에 정화하여 방류하여야 하는데, 이러한 분뇨나 축산폐수를 발효시켜 퇴비로 재활용하기도 한다. 이와 같이 분뇨나 축산폐수를 발효시키는 경우에는 먼저 고형분과 액상분을 분리한 다음, 고형분은 발효시키고 액상분은 정화하여 방류한다. 그런데 상기 액상분이 제거된 고형분에도 다량의 수분이 함유되어 있기 때문에 고형분을 그대로 발효시키는 경우에는 수분에 의해 발효가 제대로 되지 않거나 발효에 상당히 긴 시간이 소요된다. 따라서 분뇨나 축산폐수의 발효전에 걸러진 고형분의 수분함량을 낮춘 다음 발효시켜야 하는데, 고형분에 함유된 수분의 양을 낮추기 위해서는 별도의 장치를 구비하여 고형분을 압착하는 등의 처리를 하여야 하므로 별도의 장치가 필요할 뿐만 아니라 처리공정도 복잡하므로 종래에는 수분을 조절하기 위해 수분조절제를 투입하여 비교적 용이하게 수분을 조절하였다. 한편 종래에는 수분조절제로 톱밥을 사용하였는데, 전술한 바와 같이 고형분 자체의 수분함량은 낮추지 않은 채 톱밥만을 투입하기 때문에 톱밥이 비교적 많은 양 소요되어 전체적인 처리비용이 상승되었다.If manure or livestock wastewater is discharged as it is, it will cause serious environmental pollution. Therefore, manure or livestock wastewater can be fermented and recycled as compost. In this way, when fermentation of manure or livestock wastewater, the solids and liquids are separated first, then the solids are fermented and the liquids are purified and discharged. However, since the solid content from which the liquid component is removed contains a large amount of water, when the solid content is fermented as it is, the fermentation is not properly performed by water or takes a long time for fermentation. Therefore, before the fermentation of manure or livestock waste water, the content of the filtered solids should be lowered and then fermented.In order to lower the amount of water contained in the solids, a separate device must be provided for the treatment of pressing solids, etc. Not only is it necessary, but also a complicated treatment process, it was conventionally controlled to adjust moisture relatively easily by adding a moisture control agent to control moisture. Meanwhile, in the past, sawdust was used as a moisture control agent. As described above, since only sawdust was added without lowering the moisture content of the solid content itself, sawdust was consumed in a relatively large amount, thereby increasing the overall treatment cost.

또한, 고형분이 걸려진 액상의 폐수는 별도의 처리과정을 거쳐 정화되어 방류된다. 그런데 이 액상의 폐수 중에는 수질부영양화를 초래하는 질소와 인이 다량 함유되어 있는데, 폐수 중의 질소와 인을 제거하기 위해서는 고도의 처리시설 및 고비용이 소요된다. 따라서 축산농가 중에는 폐수 중의 질소와 인을 기준치 이하로 제거하지 않은 채 방류하기도 하여 심각한 수질오염을 유발시킨다.In addition, the wastewater of the liquid hung solid is purified and discharged through a separate treatment process. However, this liquid wastewater contains a large amount of nitrogen and phosphorus that causes water eutrophication, and it requires a high treatment facility and a high cost to remove nitrogen and phosphorus from the wastewater. Therefore, some livestock farmers discharge nitrogen and phosphorus in the wastewater without removing them below the standard value, causing serious water pollution.

본 발명은 전술한 바와 같은 문제점을 해결하기 위한 것으로서, 본 발명의 목적은 분뇨나 축산폐수를 속성발효시켜 고형분은 퇴비로 액상분은 액비로 재활용함으로써 경제적일 뿐만 아니라 처리과정에서 부산물이 발생되지 않는 무방류 처리방법으로 환경친화적인 새로운 구성의 축산분뇨 및 폐수의 무방류 처리방법을 제공하고자 하는 것이다.The present invention is to solve the problems as described above, the object of the present invention is to ferment the manure or livestock waste water fast to recycle the solid content as liquid compost to liquid waste as well as economical by-products do not occur in the process It is to provide a new environment-friendly composition of livestock manure and wastewater.

A subsidiary material mixing process for preparing conditions for activating microorganisms by mixing sawdust or chaff and mixing vermiculite with a moisture control agent, a fermentation process for fermenting manure and livestock wastewater in which the moisture control agent is mixed, and the fermentation process. It comprises a separation process for separating the livestock manure and wastewater into solid and liquid component, the solid component is post-processed to produce a compost, the liquid component is characterized in that the liquid-free fertilization treatment method of manure and livestock wastewater Is provided.

본 발명의 다른 특징에 따르면, 상기 질석은 가열처리되어 박리팽창된 것을 특징으로 하는 분뇨 및 축산폐수의 무방류 처리방법이 제공된다.According to another feature of the present invention, the vermiculite is heated and peeled and expanded to provide a non-discharge treatment method of manure and livestock wastewater.

본 발명의 또 다른 특징에 따르면, 상기 농축과정이 이루어지는 농축조의 내부압력은 대기압보다 낮은 압력으로 조절되어 농축조로 유입된 분뇨 및 축산폐수 중의 수분이 100℃ 보다 낮은 온도에서 증발되도록 된 것을 특징으로 하는 분뇨 및 축산폐수의 무방류 처리방법이 제공된다.According to another feature of the present invention, the internal pressure of the concentration tank in which the concentration process is performed is controlled to a pressure lower than atmospheric pressure so that the water in the manure and livestock wastewater introduced into the concentration tank is evaporated at a temperature lower than 100 ℃ A non-discharge treatment method for manure and livestock wastewater is provided.

이하, 본 발명의 바람직한 실시예를 첨부한 도면에 의거하여 설명하면 다음과 같다. 도 1과 도 2는 본 발명에 의한 바람직한 실시예를 보인 공정도와 처리시스템의 개략도이다.Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings. 1 and 2 are schematic diagrams of a process diagram and a processing system showing a preferred embodiment according to the present invention.

먼저, 분뇨 및 축산폐수에서 모래 등의 협잡물을 제거한 다음, 저장조(10)에 저장하여 소정일 체류시킨다. 이는 분뇨 및 축산폐수의 유량 및 오염물질의 부하량을 균등하게 하여 후처리공정에 부하가 생기지 않게 함으로써, 처리의 안정화를 도모하기 위한 것이다. 이때 저장조(10)에는 블로워(12) 등을 이용해 공기를 공급하여서 고형물이 침적되는 것을 방지한다.First, to remove impurities such as sand from the manure and livestock waste water, and then stored in the storage tank 10 to stay for a predetermined day. This is to stabilize the treatment by equalizing the flow rate of the manure and livestock wastewater and the load of pollutants so that no load is generated in the post-treatment process. At this time, the reservoir 10 is supplied with air using a blower 12 to prevent the solids from being deposited.

그리고 상기 저장조(10)에 체류되어 성상 등이 균등화된 분뇨 및 축산폐수를 농축조(20)로 이송시켜 분뇨 및 축산폐수에 함유된 수분 중의 일부를 제거시킨다. 이 농축조(20)에서는 분뇨 및 축산폐수를 가열하여 수분을 증발시키는데, 이때 분뇨 및 축산폐수를 가열시키는데 필요한 에너지를 절감하기 위해 본 발명에서는 농축조(20)의 내부 압력을 대기압보다 낮은 압력으로 유지하여 물의 비등점을 100℃ 이하로 낮춘다. 따라서 상기 농축조 내의 압력을 -76mmHg정도의 진공압으로 유지하고, 내부 온도를 60~70℃로 유지하는데, 바람직하게는 이와 같은 농축조(20)에서 축산폐수의 수분을 10~15%정도 증발농축시킨다. 그리고 이때 증발효율을 증가시키고 고형물이 침적되는 것을 방지하기 위해 교반기로 교반시킨다. 이와 같이 농축조(20)에서 처리하는 과정에서는 분뇨 및 축산폐수에 함유된 수분의 일부가 증발되어 후처리공정에서 혼합되는 수분조절제의 사용량을 감소시킬 수 있을 뿐만 아니라 각종 병원균 및 기생충란이 사멸되고 분뇨 및 축산폐수의 유기물은 열분해가 수행되어 미생물이 분해하기 쉬운 저분자물질로 변화된다.Then, the manure and livestock wastewater, which is retained in the storage tank 10 and is equalized, is transferred to the concentration tank 20 to remove some of the water contained in the manure and livestock wastewater. In the concentration tank 20, the manure and livestock wastewater is heated to evaporate water. In this invention, in order to reduce the energy required to heat the manure and livestock wastewater, the internal pressure of the concentration tank 20 is maintained at a pressure lower than atmospheric pressure. Lower the boiling point of water to 100 ° C or lower. Therefore, the pressure in the concentration tank is maintained at a vacuum pressure of about -76 mmHg, and the internal temperature is maintained at 60 to 70 ° C. Preferably, the concentration of the livestock wastewater in the concentration tank 20 is evaporated to 10-15%. . And then it is stirred with a stirrer to increase the evaporation efficiency and to prevent solids from depositing. As such, in the process of the concentration tank 20, a part of the water contained in the manure and livestock waste water is evaporated to reduce the amount of the moisture control agent mixed in the post-treatment process, as well as kill various pathogens and parasites, The organic matter in the livestock wastewater is thermally decomposed to change into low molecular weight substances which are easily decomposed by microorganisms.

이어서 농축된 분뇨 및 축산폐수를 혼합배양조(30)로 유입시키는데, 이 혼합배양조(30)에서는 후공정인 발효과정에서 속성으로 발효가 진행되도록 하기 위해 미생물이 활성화될 수 있는 최적조건을 제공한다. 일반적으로 발효는 적정C/N비와 수분함량이 요구되는데, 적절한 조건을 맞추어주지 못하면 발효기간이 길어지거나 충분히 발효되지 못한 저질의 퇴비가 제조된다. 따라서 본 발명에서는 적정 C/N비를 맞추어주기 위해 탄소공급원으로 톱밥, 왕겨, 볏집 등을 투입하여 C/N비가 25~35정도 되도록 한다. 그리고 수분함량을 조절하기 위해 수분조절제로 질석을 투입한다. 질석(Vermiculite)은 SiO2, MgO, AL2O3를 주성분으로 하는 점토광물로서, 수분보유력이 크고 영양물질의 흡착능력이 크며, 토양의 산성화를 방지하기 때문에 흔히 토지개량제로 사용된다. 이러한 질석을 분뇨 및 축산폐수에 혼합하면 수분조절은 물론 악취발생방지에 탁월하고 산화발효의 효율을 증대시킨다. 특히, 질석은 가열하면 층간수가 탈수되면서 발생하는 수증기에 압력에 의해 3~30배까지 박리팽창하는데, 박리팽창된 질석은 수분흡수율이 매우 높아 300~500중량%의 물을 흡수할 뿐만 아니라 다공성이여서 표면적이 넓기 때문에 미생물의 담체로서의 역할도 한다. 또한, 질석은 미생물에게 영양물질 및 미네랄을 지속적으로 제공하여 미생물의 활동을 증가시키는 등 미생물이 활성화될 수 있는 환경을 조성하여 미생물의 활성도를 높인다. 따라서 바람직하게는 박리팽화된 질석을 사용하는데, 이와 같이 질석을 혼합하면 전술한 바와 같은, 효과를 얻을 수 있을 뿐만 아니라 질석에 함유된 미네랄성분에 의해 최종적으로 생산되는 퇴비의 품질이 상승된다. 미설명부호 32는 부재료 투입장치이다.Subsequently, the concentrated manure and livestock wastewater are introduced into the mixed culture tank 30. The mixed culture tank 30 provides optimum conditions for activating microorganisms so that fermentation proceeds as a property during the fermentation process, which is a post-process. do. In general, fermentation requires an appropriate C / N ratio and water content. If the proper conditions are not met, fermentation may be prolonged or poorly produced. Therefore, in the present invention, the sawtooth, rice hulls, rice hulls, etc. as a carbon supply source to adjust the appropriate C / N ratio so that the C / N ratio is about 25 to 35. And vermiculite is added as a moisture control agent to control the moisture content. Vermiculite is a clay mineral composed mainly of SiO 2 , MgO, and AL 2 O 3 , and is often used as a land-improving agent because of its high water retention, high adsorption capacity of nutrients, and prevention of soil acidification. When the vermiculite is mixed with manure and livestock wastewater, it is excellent in controlling moisture as well as prevention of odor and increases the efficiency of oxidation fermentation. In particular, vermiculite is exfoliated and expanded up to 3 to 30 times by pressure in water vapor generated when interlayer water is dehydrated when heated.The exfoliated and expanded vermiculite absorbs 300 to 500% by weight of water due to its high water absorption and is porous. Because of its large surface area, it also serves as a carrier for microorganisms. In addition, vermiculite increases the activity of microorganisms by continuously providing nutrients and minerals to microorganisms, thereby creating an environment in which microorganisms can be activated. Therefore, it is preferable to use exfoliated expanded vermiculite. Mixing vermiculite in this way can not only achieve the effects described above, but also increase the quality of the compost finally produced by the mineral component contained in the vermiculite. Reference numeral 32 is a material input device.

한편, 기숙성된 퇴비와 액비를 상기 혼합배양조(30)에 반송시켜 발효에 필요한 미생물을 공급하는데, 이와 같이 기숙성된 퇴비를 반송시킴으로써 상기 톱밥이나 질석 등과 같은 부재료의 사용량을 감소시킬 수 있다. 이와 같이 처리되는 상기 혼합배양조(30)는 미생물이 활성화되도록 호기상태를 유지하여야 하므로 공기를 주입하면서 교반기로 교반하여 호기성상태를 유지시키고 온도를 55℃정도로 유지시킨다.On the other hand, by feeding the matured compost and liquid fertilizer to the mixed culture tank 30 to supply the microorganisms required for fermentation, by returning the matured compost can reduce the amount of subsidiary materials such as sawdust, vermiculite, etc. . The mixed culture tank 30 treated as described above should maintain an aerobic state to activate microorganisms, so that the mixture is stirred with a stirrer while injecting air to maintain an aerobic state and maintain a temperature of about 55 ° C.

이와 같이 처리하여 미생물이 활성화될 수 있는 최적의 조건을 마련하여 미생물의 활성도가 높아지면, 분뇨 및 축산폐수를 발효조(40)로 유입시킨다. 이 발효조(40)에서는 미생물에 의해 분뇨 및 축산폐수가 발효되는데, 이때 발효조(40) 내의 온도를 50~60℃로 유지시켜 발효가 속성으로 진행되도록 하는데, 약 3~5일정도 발효시킨다. 이때 상기 발효조(40)에 공기를 주입하여 호기상태가 유지되도록 하며, 교반기로 교반하여 처리물과 공기가 고르게 접촉되도록 하는데, 필요에 따라서는 이와 같은 발효조(40)를 다수개 설치할 수도 있다.By treating in this way to provide the optimum conditions for the microorganism to be activated, when the activity of the microorganism increases, manure and livestock wastewater is introduced into the fermentation tank (40). In the fermentation tank 40, manure and livestock wastewater are fermented by microorganisms, and at this time, the temperature in the fermentation tank 40 is maintained at 50 to 60 ° C. so that the fermentation proceeds as an attribute, and fermentation is performed for about 3 to 5 days. At this time, the aerobic state is maintained by injecting air into the fermentation tank 40, and agitated with a stirrer to evenly contact the processing material and air, if necessary, a plurality of such fermentation tank 40 may be provided.

상기 발효조(40)에서 분뇨 및 축산폐수가 발효되면 분리기(50)로 고형분과 액상분을 분리한다. 이어서 분리된 고형분은 고품질의 퇴비가 되도록 퇴비숙성건조조(60)에서 처리하는데, 건조조의 온도를 40℃정도로 유지하여 발효과정에서 생성된 발효부산물과 잔류하는 유기물질이 충분히 발효되도록 한다. 그리고 이때 가열된 공기를 주입하여 호기상태를 만들어 주면서 동시에 퇴비가 건조되도록 하는데, 퇴비가 뭉쳐지지 않도록 교반기로 교반하면서 약 5~15일정도 체류시켜 숙성건조시킨다. 그리고 숙성된 퇴비는 조쇄선별기(62)를 거쳐 미제거된 이물질을 제거한 다음, 소정단위로 포장한다.When the manure and livestock wastewater is fermented in the fermentation tank 40, the solid and liquid components are separated by the separator 50. Subsequently, the separated solids are treated in the compost aging drying 60 to ensure high quality compost. The temperature of the drying bath is maintained at about 40 ° C. so that the fermentation by-products generated during the fermentation process and the remaining organic substances are sufficiently fermented. At this time, the heated air is injected to create an aerobic state and at the same time to allow the compost to dry, while the compost does not agglomerate by stirring with a stirrer to dry for about 5 to 15 days. And the aged compost is removed by the debris separator 62, and then packaged in a predetermined unit.

한편, 상기 분리기(50)에서 분리된 액상분은 발효액비생산조(80)로 이송된다. 이 발효액비생산조(80)에는 공기를 주입하여 호기성상태를 유지하면서 반응조의 온도를 약 50℃정도로 유지시킨다. 이때 바람직하게는 박리 팽화된 질석을 충진하여 액비완숙의 효율을 높이고 액비의 품질을 높인다. 그리고 완숙된 액비는 여과기(82)로 여과하여 투입된 질석과 액비에 포함되어 있는 기타 고형물을 제거한다. 이와 같이 하여 생산된 액비는 저장조(84)에서 체류시켜 품질을 균등화시킨 후, 소정단위로 포장한다.On the other hand, the liquid component separated from the separator 50 is transferred to the fermentation broth ratio production tank (80). Air is injected into the fermentation broth ratio production tank 80 to maintain the temperature of the reaction tank at about 50 ° C while maintaining an aerobic state. In this case, preferably, the peeled and expanded expanded vermiculite is filled to increase the efficiency of liquid completion and increase the quality of the liquid ratio. And the mature liquid ratio is filtered by the filter 82 to remove the added vermiculite and other solids contained in the liquid ratio. The liquid ratio thus produced is retained in the reservoir 84 to equalize the quality, and then packaged in predetermined units.

이상에서와 같이 본 발명에 의하면, 분뇨 및 축산폐수를 발효시켜 고형분은 퇴비로 액상분은 액비로 재활용함으로써 경제적일 뿐만 아니라 무방류 처리방법으로 환경친화적인 새로운 구성의 축산분뇨 및 폐수의 무방류 처리방법을 제공할 수 있다. 이러한 본 발명은 발효전에 분뇨 및 축산폐수에 함유된 수분의 일부를 제거함으로써 수분조절제의 투입양을 절감할 수 있으며, 혼합배양조에 미생물을 활성화시킨 후 발효조에서 발효시키기 때문에 발효기간을 단축시킬 수 있다. 또한, 종래에는 분뇨 등을 발효시키는 전체과정 중에서 발효가 일어나는 발효조의 온도만 소정온도로 유지시키나, 본 발명에서는 전체처리과정에서 각 처리조들의 온도를 적정수준으로 유지시킴으로서 발효에 소요되는 시간을 단축시킬 수 있다. 이와 같은 본 발명에 의하면 질석에 함유된 미네랄성분에 의해 고품질의 퇴비를 얻을 수 있다.As described above, according to the present invention, the manure and livestock wastewater are fermented, the solid content is composted, and the liquid content is recycled into the liquid fertilizer.
