Description
본 발명은 토양권의 자연정화력을 이용하여 일반가정이나 공공건물에서 배출되는 각종 생쓰레기 및 오수를 지렁이를 이용하여 정화처리하는 방법 및 그 장치에 관한 것이다.The present invention relates to a method and an apparatus for purifying various live garbage and sewage discharged from a general household or a public building by using an earthworm using a natural purification power of the soil zone.
오수 및 오탁물질에 의한 공공수역의 오탁진행은 광범위한 규모로 진행중이며, 그 정화대책으로서는 물리적 수단, 화학적 수단, 생물적 수단을 조합시켜 오수 및 오탁물질의 각종 정화처리를 행하여서, 어느 일정 수질기준을 정해 공공수역인 하천, 바다 등에 방류시키는 대책을 현재 세계 각국에서 실시중이지만, 영양염(질소분 또는 인분)의 처리가 불충분하여 완전하게 오탁물질을 제거하기까지는 이르지 못하는 것이 현실정이다.Pollution progress in public waters by sewage and pollutants is being carried out on a wide scale. As a countermeasure, various purification treatments of sewage and pollutants are carried out by combining physical, chemical and biological means. Although measures are currently being taken in various countries around the world for the purpose of establishing and discharging public waters such as rivers and seas, the treatment of nutrients (nitrogen or phosphorus) is insufficient and it is not possible to completely remove contaminants.
상기한 오수정화의 실정을 해결하기 위해 활성오니법에 의한 오수처리기술이 개발되었다.In order to solve the above situation of sewage purification, a sewage treatment technique using an activated sludge method has been developed.
그러나 이러한 활성오니법의 출현에 의해 유기물을 소면적의 장치에서 제거율90% 이상으로 하기까지 발전되어 세계 각국에서 하수처리방식으로 적용하고 있지만, 수용성 유기물을 미생물의 체중을 전환시킨 기술에 그치고 있어서, 그 처리를 둘러싸고 해결해야 할 여러 가지 문제점을 야기하고 있었다.However, with the advent of the activated sludge method, organic materials have been developed to have a removal rate of 90% or more in a small-area device, and many countries have applied them as sewage treatment methods. It has caused a number of problems that need to be addressed around the process.
학술적 표현으로 균체전환율이라고 칭하고 있는 활성오니법에서는 50% 이상이 잉여오니(고체)로 회수되어서, 고액(固液)분리, 탈수, 건조, 소거등의 작업을 하지 않으면 안되는 어중간한 기술로 끝나고 있다.In the activated sludge method, which is called the cell conversion rate in academic terms, more than 50% of the sludge is recovered as a surplus sludge (solid), ending with a halfway technique that must be performed for solid-liquid separation, dehydration, drying, and eradication.
또, 물리적처리법은 침전에 의한 고액분리법이 주체가 되어 1차처리라 칭하고 활성오니법을 2차처리, 그외의 고급처리를 3차처리라고 분류할 수 있지만, 모두 장치내에 남아있는 잉여오니를 꺼내어 별도로 처리하지 않으면 안된다고 하는 문제점이 있다. 따라서, 상술한 활성오니법에 의한 오수처리 기술의 문제점을 해결하기 위해서, 현재 각국에서는 오수의 토양에 의한 처리법이 개발되어 실시되고 있다.In the physical treatment method, the solid-liquid separation method by sedimentation is mainly a primary treatment, and the activated sludge process can be classified as a secondary treatment and other advanced treatments as a tertiary treatment. There is a problem that it must be handled separately. Therefore, in order to solve the problem of the sewage treatment technique by the activated sludge method mentioned above, the treatment method by the soil of sewage is currently developed and implemented in each country.
이 토양에 의한 처리법, 즉, 토양정화법은 지표하 1m 정도의 토양에 생존하는 토양미생물, 식물뿌리등을 활용하고, 또 토양 그 자체가 갖고 있는 물리적, 화학적 성질을 이용하여 오수 및 오니를 정화하고자 하는 공법으로서, 토양중의 특수한 물의 운동의 하나인 모세관사이폰 침윤현상을 토양학적으로 응용하여 지하수의 오염방지, 토양중의 오니의 분해촉진, 악취의 제거등에 토양표면층의 미생물의 활동을 활용하는 처리방식이다.This soil treatment method, namely soil purification method, utilizes soil microorganisms and plant roots that live in the soil about 1m below the surface, and purifies sewage and sludge using the physical and chemical properties of the soil itself. The method is to apply the capillary siphon infiltration phenomenon, which is one of the special water movements in the soil, to utilize the microbial activity of the soil surface layer to prevent groundwater contamination, promote the decomposition of sludge in the soil, and remove odors. That's how it works.
상기한 토양정화법에 의한 처리방식에 의하면, 종래의 오수처리기술에 비해 오수 및 오니의 처리효과가 극히 우수하지만, 오니의 분해효율을 더욱 높이기 위한 방법의 도입이 더욱 요망되고 있다.According to the treatment method by the above-mentioned soil purification method, the treatment effect of sewage and sludge is extremely superior to the conventional sewage treatment technique, but it is further desired to introduce a method for further increasing the decomposition efficiency of sludge.
상기한 토양정화법을 대별하면, 토양피복형과 토양트렌치형으로 나눌 수 있는데, 전자는 주로 탈취에, 후자는 주로 오수의 고도처리에 중점을 두고 있으며, 부차적으로 원생동물, 후생동물의 이용이 조합되어 있었다.The soil purification method can be roughly divided into soil coating type and soil trench type. The former mainly focuses on deodorization and the latter mainly focuses on the advanced treatment of sewage. It was.
이에 대해서 본발명은 지렁이의 난포(卵包)를 토양정화법을 토대로 한 오수, 오니처리장치에 추가적으로 공급하는 것에 의해 잉여오니의 발생량을 0 또는 감량하고자 하는 것이다.In this regard, the present invention intends to reduce or reduce the amount of surplus sludge generated by additionally supplying the worms of the earthworm to the sewage and sludge treatment apparatus based on the soil purification method.
가장 실용성이 높은 것은 소규모의 가정용 처리장치로서, 잉여오니의 처리가 지렁이에 의해 완전하게 행해진다.The most practical is a small household treatment apparatus, in which the treatment of surplus sludge is completely performed by the earthworm.
그 원리는 오수의 오니, 토양중의 오니등과 함께 지렁이가 매일 자기의 체중과 동일한 정도의 유기물, 세균, 토양등을 먹고 반드시 지표면으로 운반하여 배설하는 습성을 이용한 것이다.The principle is that the earthworm eats organic matter, bacteria, soil, etc. equal to its own weight every day along with the sewage sludge and the sludge in the soil.

제1도 및 제2도는 본 발명의 오니감량방법을 이용하는 한가지 예인 토양식 부엌 쓰레기 처리장치(1)를 나타내는 평면개략도 및 단면개략도이다.1 and 2 are plan and schematic views showing a soil type kitchen waste disposal apparatus 1 as one example using the sludge reduction method of the present invention.
이 처리장치는 부엌에서 배출되는 음식쓰레기 등의 부엌쓰레기를 완전하게 처리하기 위한 것으로서, 지표밑 약 45㎝ 정도의 깊이에 둘레 가장자리를 지표면측으로 높이가 약 15㎝ 정도로 되도록 절곡한 염화비닐제의 지수판(2)을 설치하고 그 위에 다수의 구멍이 표면에 형성되어 있는 맥주나 청량음료 운반용 상자등의 플라스틱 상자체(5)를 얹고 다시 그 상자체(5)위에 상부에 덮개(3)를 보유하는 염화비닐제의 원통형 본체(4)를 설치하며, 부엌으로부터의 배출물이 장치내로 유입될 수 있도록 본체(4)의 측벽에 관통구멍을 형성하여 유입관(6)을 삽통시켜 구성된다.This treatment device is for completely processing kitchen waste such as food waste discharged from the kitchen. The vinyl chloride index plate is bent at a depth of about 45 cm below the ground surface to a height of about 15 cm to the ground surface side. (2) and a plastic box (5) such as a beer or soft drink carrying box having a plurality of holes formed on the surface thereof, and again having a lid (3) on the box (5). The cylindrical body 4 made of vinyl chloride is provided, and a through hole is formed in the side wall of the main body 4 so that the discharge from the kitchen can be introduced into the apparatus, and the inlet pipe 6 is inserted.
처리장치(1)를 설치하기 위해 파낸 흙은 매설토(7)로 사용하여 매설되는데, 이때 매설토(7)에 나무껍질 등을 분쇄하여 혼합하면 토양의 모세관사이폰 침윤작용이 보다 용이하게 된다.Soil excavated to install the treatment device 1 is buried using the buried soil (7), at this time, by crushing and mixing the bark and the like in the buried soil (7) to facilitate the capillary siphon infiltration of the soil. .
여기서 언급하는 모세관사이폰 침윤현상이란, 유입되는 오수 및 오니가 표면장력에 의해 토양 내의 공극을 통하여 상승하는 모세관 현상과, 또 대기압의 작용으로 오수가 오수면의 높이보다 높은 곳으로 일단 상승된 후, 낮은 곳으로 이동하는 사이폰현상과 상기한 오수 및 오니가 토양입자의 좁은 공극을 상방 또는 측방으로 침윤한 후에 하강하는 현상을 총칭하는 것이다.The capillary siphon infiltration referred to herein refers to a capillary phenomenon in which the incoming sewage and sludge rise through the voids in the soil due to surface tension, and after the sewage is elevated to a height higher than the height of the sewage surface by the action of atmospheric pressure, It is a generic term for the siphon phenomena moving to a lower place, and the sewage and sludge as described above fall down after infiltrating the narrow pores of the soil particles upwardly or laterally.
상기한 구성의 처리장치(1)에서 부엌으로부터 유입관(6)을 통해 장치내부로 유입되는 음식쓰레기등의 유기물을 함유하는 오수 및 오니가 지수판(2)에 저류된 후, 장치주변의 매설토(7) 및 지표층토양(8)사이에서 상기한 현상에 의해 침윤되어 토양권내의 미생물의 작용에 의해 분해되어 정화가 행해진다(제2도의 화살표참조)In the processing apparatus 1 of the above-mentioned structure, the sewage and sludge containing organic matter, such as food waste which flows into the apparatus from the kitchen through the inflow pipe 6, is stored in the index plate 2, (7) and surface layer soils (8) are infiltrated by the above-mentioned phenomenon, decomposed by the action of microorganisms in the soil zone and purified (see arrows in FIG. 2).
본발명은 상기한 바와 같은 현상에 의해서도 분해되지 못하고 잔존하는 잉여 오니를 지렁이를 이용하여 완전하게 분해하는 것으로, 상기한 토양식 부엌쓰레기 처리장치(1)의 덮개(3)는 열고, 처리장치(1)내부에 지렁이의 난포를 투입하면, 온도, 수분, 영양조건에 의해 지렁이의 생존량이 결정된다.The present invention is to completely decompose the surplus sludge that is not decomposed by the above-described phenomenon by using an earthworm, and the cover 3 of the soil type kitchen garbage processing apparatus 1 is opened, and the treatment apparatus ( 1) When the worm's follicles are injected inside, the survival rate of the earthworm is determined by temperature, moisture, and nutritional conditions.
난포는 토양중의 환경조건에 맞으면 연속적으로 공급되는 영양의 범위, 즉, 유기물의 공급범위 내에서 부화생육하게 된다.Follicles hatch and grow within the range of nutrients that are continuously supplied, i.
이와 같이 부화생육되는 지렁이가 유기물을 매일 자기의 체중과 동일한 양만큼 먹고 지표면에 배설하게 되므로, 처리장치(1)내에는 잉여오니가 거의 잔존하지 않게 된다.In this way, the hatched worms eat organic matter by the same amount as their body weight every day and are excreted on the ground, so that surplus sludge hardly remains in the treatment apparatus 1.
이와 같은 처리방법에 의하면, 유기물농도가 500ppm 정도인 부엌배수를 5ppm 이하로 낮출 수 있다.According to this treatment method, the kitchen wastewater having an organic concentration of about 500 ppm can be lowered to 5 ppm or less.
이하, 본발명의 지렁이를 이용한 오니감량방법을 적용하는 다른 오수처리장치에 대하여 설명한다.Hereinafter, another wastewater treatment apparatus using the sludge reduction method using the earthworm of the present invention will be described.

부호(9)는 혐기성 또는 호기성 여상조를 나타내며, 부호(10)은 모세관침윤 트렌치를 나타낸다. 상기한 여상조(9)를 매설할 때에는 사권에 매설지점을 파고 부동침하 방지의 기초공사를 한 후에 그 위에 염화비닐판을 상부를 용접하여 제작한 상부가 개방되어 있는 직육면체 형상의 지수상자체(14)가 설치되어 있고, 상기한 지수상자체(14)내부에는 표면에 다수의 구멍이 형성되어 있는 맥주나 청량음료 운반용 상자체(15)가 복수개 적층되어 있다.The sign 9 represents an anaerobic or aerobic phase filter, and the sign 10 represents a capillary infiltration trench. When embedding the filter tank (9), a rectangular parallelepiped shaped box (14) having an open upper part made by digging a buried point in the winding mill and performing basic work of preventing anti-sedimentation, and then welding the upper part of a vinyl chloride plate thereon. Is provided, and a plurality of boxes for transporting beer or soft drinks 15 having a plurality of holes formed on the surface thereof are stacked in the inside of the still water box 14.
상기한 상자체(15)가 적층되어 있는 상부에는 제4도에 도시되어 있는 바와 같이 유공강철통이나 필름통등의 접촉여재를 부직포주머니에 넣어 일정한 부피의 접촉여재 주머니로 하여 산형상을 이루도록 가득 채운 후 그 위에 매설토를 채운다.As shown in FIG. 4, the upper part of the box body 15 is stacked to form a mountain-shaped shape by putting a contact medium such as a perforated steel tube or a film tube into a nonwoven fabric bag and forming a contact volume bag of a constant volume. After filling, fill up the soil.
이와 같이 산형상으로 접촉여재를 채우는 것은 토양권 내의 미생물이 여상조(9)내로 원할하게 공급되도록 하기 위한 목적이다. 또한 접촉여재로서 유공강철통이나 필름등을 사용하는 것은, 이들 재료의 성분이 철이기 때문에 산화작용이 촉진되어 접촉여재에 접촉되는 오수의 분해가 촉진되기 때문이다.Filling the contact medium in the form of an acid as described above is for the purpose of smoothly supplying microorganisms in the soil zone into the filter tank (9). In addition, the use of a porous steel tube or a film as a contact medium is because the components of these materials are iron, which promotes oxidation and promotes decomposition of sewage in contact with the contact medium.
상기한 여상조(9)가 매설되어 매설토로 피복될때의 매설토의 깊이는 산형상으로 채워지는 접촉여재의 정상부에서 지표면까지의 거리가 약20㎝ 정도, 또한, 그 좌우측 부분으로부터 지표면까지의 거리는 약 30㎝ 정도가 바람직하다.The depth of the buried soil when the filter tank 9 is buried and covered with buried soil is about 20 cm from the top of the contact medium filled with the mountain shape to the ground surface, and the distance from the left and right portions to the ground surface is about 30 cm. About cm is preferable.
이는 토양전내의 미생물의 활동이 가장 활발한 깊이이기 때문이다. 물론 여상조의 용량은 유입되는 오수의 양에 따라 변경 가능하다.This is because the activity of microorganisms in the soil field is the most active depth. Of course, the capacity of the filter tank can be changed depending on the amount of sewage introduced.
그리고 상기한 여상조(9)의 합성수지재 맨홀(13)을 매개로 하여 접속되는 모세관침윤 트렌치(10)는 이하의 방식으로 구성되어 있다.The capillary infiltration trench 10 connected through the synthetic resin manhole 13 of the filter tank 9 is constructed in the following manner.
먼저 깊이가 60㎝ 정도 되도록 상기한 트렌치(10)가 매설될 지역의 토양을 파낸 후, 부동침하방지의 기초공사를 하고, 폭이 약 20㎝ 정도, 높이가 약 20㎝ 가 되도록 염화비닐제의 지수판(16)을 수밀시공하여 부설한다.First, dig the soil in the area where the trench 10 is to be buried so as to have a depth of about 60 cm, and then carry out the foundation work to prevent anti-sedimentation, and the width of about 20 cm and the height of about 20 cm The index plate 16 is watertightly laid and laid.
부설되는 지수판(16)의 길이는 유입되는 오수량에 따라 변경할 수 있지만, 통상 1인당 2m 정도의 길이로 하는 것이 바람직하다.The length of the index plate 16 to be installed can be changed depending on the amount of sewage to be introduced, but it is usually preferred to have a length of about 2m per person.
또, 상기한 유공관(17)의 말단부는 지표면측으로 만곡성형하여 상기한 유공관(17)을 점검할 수 있도록 측정구(18)를 설치한다.In addition, the distal end portion of the above-described air hole tube 17 is formed to be curved toward the ground surface side, so that the measuring tool 18 is provided so that the above-described hole hole 17 can be inspected.
이와 같은 방식으로 모세관침윤 트렌치(10)를 설치한 후, 매설토(7)를 매설한다. 이 경우 매설토(7)는 상술한 모세관사이폰 침윤현상이 원할하게 이루어지고, 미생물의 활동이 촉진될 수 있도록 분탄(粉炭), 나무껍질, 낙엽 등을 가공성형하고, 이것에 검은 색을 띠는 화산회를 적정량 혼합하여 제조되는 인공토양을 사용하는 것이 바람직하다. 또한 상기한 부엌쓰레기 처리장치(1) 및 여상조(9)를 매설하기 위한 매설토로서도 상기한 인공토양을 이용하는 것이 바람직하다.After the capillary infiltration trench 10 is installed in this manner, the buried soil 7 is embedded. In this case, the buried soil (7) is smoothly formed in the above-described capillary siphon infiltration phenomenon, and processed to form the coal, bark, fallen leaves, etc. so as to promote the activity of microorganisms, it has a black color It is preferable to use an artificial soil prepared by mixing an appropriate amount of volcanic ash. Moreover, it is preferable to use the said artificial soil as embedding soil for embedding the said kitchen waste processing apparatus 1 and the filter tank 9 above.
상기한 바와 같이 구성된 여상조(9)에는 화장실배수, 및 기타의 생활오수가 유입된다. 화장실에서 배출되는 오니는 주로 분뇨와 화장지가 주가 되는 오탁물로서, 분뇨와 화장지는 여상조 밑으로 침전된 후 시간이 경과함에 따라 가스를 발생시켜 부상되어 상기한 접촉여재(19)에서 여과된 후 매설토(7)내에 보류된다. 여상조(9)내에서 오수면(20)을 지표하 30㎝ 로 하면, 상술한 바와 같이 모세관사이폰 침윤현상에 의해 1차적으로 처리되며, 상기한 매설토(7)내에 지렁이의 난포를 공급하면, 부화증식하여 접촉여재(19) 및 매설토(7)내의 유기물을 먹고 지표면으로 이동하여 매설토(7)내의 유기물을 먹고 지표면으로 이동하여 배설하게 된다. 따라서, 지렁이에 의한 여상조(9)의 정화능력을 한층 높일 수 있게 된다.The toilet tank 9 constructed as described above introduces toilet drainage and other household wastewater. Sludge discharged from the toilet is mainly a manure and toilet paper waste, manure and toilet paper is settled under the filtration tank and after the time is generated by the generation of gas is injured and filtered in the above contact medium (19) buried Reserved in the soil (7). If the sewage surface 20 in the filter tank 9 is 30 cm below the surface, it is primarily treated by capillary siphon infiltration as described above, and when the follicles of the earthworms are supplied into the buried soil 7, After hatching, the organic matter in the contact medium 19 and the buried soil 7 is eaten and moved to the ground, and the organic matter in the buried soil 7 is moved to the ground and excreted. Therefore, the purification ability of the filter tank 9 by an earthworm can be improved further.
여상조(9)내에 저류되어 있던 오수는 유출측 오수맨홀(12)과 오수맨홀(13)을 경유하여 모세관침윤 트렌치(10)의 유공관(17)내로 유입되어 상기한 유공관(17)의 구멍을 통해 모세관사이폰 침윤현상에 의해 매설토(7)내로 분출되어 2차 정화처리된다.The sewage stored in the filter tank 9 flows into the perforated pipe 17 of the capillary infiltration trench 10 through the outflow-side sewage manhole 12 and the sewage manhole 13 and through the hole of the perforated pipe 17 described above. By capillary siphon infiltration, it is ejected into buried soil 7 and subjected to secondary purification.
이 경우에도 상술한 바와 같이 매설토(7)내에 지렁이의 난포를 투입하여 부화증식되도록 하면, 모세관사이폰 침윤현상에 의한 정화능력을 한층 높일 수 있다.In this case, as described above, by inserting the follicles of the earthworm into the buried soil 7 to allow hatching and propagation, it is possible to further increase the purification ability by the capillary siphon infiltration phenomenon.
이상과 같은 발명에 의하면 종래에 사용되고 있었던 부엌쓰레기 처리장치나, 여상조 및 모세관침윤 트렌치를 이용한 오수정화처리장치에 지렁이의 난포를 투입하여 부화증식시켜서, 지렁이가 갖고 있고 성질을 이용하여 오수 및 오니중의 함유되어 있는 유기물을 보다 효율적으로 처리할 수 있다.According to the invention as described above, by inserting the follicles of the earthworm into the trash purification apparatus using a conventional kitchen waste treatment apparatus or a filter tank and capillary infiltration trenches, and hatching and propagation of the earthworm, the earthworm has a property of sewage and sludge The organic substance contained can be processed more efficiently.
따라서, 부엌쓰레기의 문제를 택지내에서 해결할 수 있고, 또한 그 외의 생활오수를 완전하게 정화처리할 수 있으므로 사회적, 경제적인 가치가 극히 높다.Therefore, since the problem of kitchen waste can be solved in the housing site and other living sewage can be completely purified, social and economic values are extremely high.
