Description
본 발명은 주로 폐수 및 고농도의 축산폐수를 미생물에 의해 정화하는데 이용되는 무독성메디아를 이용한 오폐수와 축산폐수 및 분뇨처리장치에 관한 것으로, 더욱 상세하게는 부착미생물 메디아와 에어순환장치에 의해 반응조 내부에 수중반응영역이 형성되도록 하고, 침전물과 부유물을 반응조로 되돌려지도록 하여 미생물 분해를 촉진시킴과 동시에 직·병렬로 연결되는 폐수처리장치 중간 중간에서 농도에 적합한 액비를 생산하고, 최종단계에서 방류수에 적합하도록 정화할 수 있도록 한 무독성메디아를 이용한 오폐수와 축산폐수 및 분뇨처리장치에 관한 것이다.The present invention mainly relates to wastewater and livestock wastewater and manure treatment apparatus using non-toxic media used to purify wastewater and high concentration livestock wastewater by microorganisms, and more specifically, inside the reactor by the attached microorganism media and air circulation system. Aqueous reaction zones are formed, and precipitates and suspended solids are returned to the reactor to promote microbial decomposition and to produce liquid ratios suitable for concentrations in the middle of the wastewater treatment system connected in series and parallel. The present invention relates to a wastewater, livestock wastewater and manure treatment device using non-toxic media capable of purification.
일반적으로 축산분뇨는 생물학적 산소요구량(Biochemical Oxygen Demand, 이하 "BOD"라 함.)이 대개 수만ppm(예, 20000ppm)을 넘는데, 종래 진동스크린법, 가압부상법, 응집제처리법, 활성슬러지법, 회전원통법(RBC법), 접촉처리법(HBC법) 등과 같이 물리, 화학, 미생물학이 동원된 많은 폐수처리방법이 있긴 하지만 축산분뇨와 같이 BOD가 높은 폐수는 처리가 곤란하여 방류수 수질에 미달된 상태로 하천에 방류하는 실정에 있으며, 이에 따라 수질 및 환경오염이 매우 심각한 지경에 이르게 되었다.In general, livestock manure has a biological oxygen demand (BOD) of more than tens of thousands of ppm (e.g., 20000 ppm). Conventional vibrating screen method, pressure flotation method, flocculant treatment method, activated sludge method, rotation Although there are many wastewater treatment methods that use physical, chemical, and microbiological methods such as cylinder method (RBC method) and contact treatment method (HBC method), waste water with high BOD, such as livestock manure, is difficult to treat, and thus it is less than discharged water quality. It is being discharged to rivers, which has led to very serious water and environmental pollution.
즉, 종래의 폐수처리방법 중 진동스크린법은 경사진 진동스크린 위로 폐수 및 폐기물을 낙하시켜 페수에 포함된 이물질은 진동스크린 위에서 걸러지도록 하고, 폐수만 진동스크린 밑으로 빠져서 분리되도록 한 것으로, 진동스크린을 움직이기 위해 전력 낭비가 심하였으며, 비교적 큰 이물질만을 제거할 뿐 방류수 기준에 맞춘 폐수를 정화하기에는 부족하였다.That is, in the conventional wastewater treatment method, the vibrating screen method is to drop the wastewater and waste onto the inclined vibrating screen so that foreign matters contained in the wastewater are filtered out on the vibrating screen, and only the wastewater falls under the vibrating screen to be separated. Electric power was wasted to move the wastewater, and it was not enough to purify the wastewater to meet the effluent standard, only to remove relatively large foreign substances.
또, 가압부상법은 반응조 밑에서 기포를 발생시켜 수중에 잔류하고 있는 이물질에 부상력을 가해 이물질이 수면위로 떠오르도록 한 다음 수면을 쓸어서 이물질을 분리하는 것으로 수면위로 떠오를 정도의 가볍고 큰 입자형태의 이물질 제거에만 효과가 있을 뿐 수중에 녹아 있는 유기물이나 매우 작은 입자형태로 된 이물질의 제거에는 실효성을 거두지 못하고 있으며, 수면 위의 이물질을 쓸어낼 때 기계적인 움직임을 주어야 하기 때문에 많은 전력을 소비하게 되는 단점을 지니고 있었다.In addition, the pressure flotation method generates bubbles under the reaction tank to apply a floating force to the foreign matter remaining in the water so that the foreign matter floats on the surface, and then removes the foreign matter by sweeping the water surface. It is effective only in the removal of organic matter dissolved in the water or the removal of foreign matter in the form of very small particles is not effective, and consumes a lot of power because it has to give mechanical movement when sweeping the foreign matter on the water surface Had.
그리고, 응집제처리법은 응집제와 같은 약품을 다량 투입하여 응집처리하는 방법으로서 고가의 응집제를 사용하여야 하기 때문에 처리비용이 매우 비싸게 되는 문제점이 있었고, 처리과정에서 사용한 응집제가 독성을 지니고 있기 때문에 곧바로 방류하지 못하고 후처리 과정을 거쳐 무독성처리를 해야 하나 이때에도 독성이 완전하게 제거되지 않아 위험하게 되는 문제점을 가지고 있었다.In addition, the coagulant treatment method is a method of coagulation treatment by adding a large amount of chemicals such as a coagulant, and thus, expensive coagulant has to be used, and thus, the treatment cost is very expensive. It must be treated non-toxic after the post-treatment process, but at this time also had the problem that the toxicity is not completely removed.
또한, 활성슬러지법은 "폭기법"이라 불리우는 것으로, 수중에서 기포를 발생시켜 물속에 다량의 산소를 공급함으로써 용존산소의 농도를 증대시켜 호기성미생물의 유기물분해 활동을 촉진하도록 된 것이었으나 움직임이 정적이어서 정화효율이 낮고, 저농도의 폐수정화에 적합하기 때문에 축산폐수와 같이 고농도의 폐수 정화에는 실효성을 거두지 못하고 있다.In addition, activated sludge method is called "aeration method", and it is designed to promote the organic decomposition of aerobic microorganisms by increasing the concentration of dissolved oxygen by generating bubbles in the water and supplying a large amount of oxygen in the water. Subsequently, since the purification efficiency is low and suitable for low concentration wastewater purification, it is not effective for the purification of high concentration wastewater like livestock wastewater.
또, 회전원통법은 다수의 구멍이 형성된 드럼의 하부는 수중으로 잠기도록, 상부는 공기중에 위치되도록 반응조의 수면에 수평하게 설치한 다음 드럼을 회전시켜 폐수의 공기 접촉시간 및 면적을 증대시킴으로써 용존산소의 농도를 증대시키도록 된 것으로, 저농도의 폐수정화에는 효과가 있으나 고농도의 축산폐수는 폐수중의 분뇨나 음식물 찌꺼기가 드럼에 끼거나 구멍을 메우게 되어 가동 중에 잦은 고장을 일으키므로, 축산폐수 정화에는 사용이 어렵게 되어 있었다.In addition, the rotary cylinder method is dissolved horizontally by installing the horizontally on the surface of the reaction tank so that the lower part of the drum formed with a plurality of holes to be submerged in water, the upper part is located in the air and then rotate the drum to increase the air contact time and area of the waste water. It is intended to increase the concentration of oxygen, but it is effective for low concentration wastewater purification, but high concentration livestock wastewater causes frequent breakdown during operation because manure and food wastes in the wastewater get stuck in drums or fill holes. Purification was difficult to use.
또한, 접촉처리법은 실처럼 가느다란 여러 가닥의 미생물부착 섬유를 수면 아래에 잠기도록 한 다음 방치하여 미생물에 의한 유기물 분해를 꾀한 것으로, 이 또한 축산폐수와 같이 고농도의 폐수정화시에는 분뇨나 음식물 찌꺼기와 같은 이물질이 미생물부착 섬유에 들러붙어서 미생물부착 섬유에 자생하는 미생물들을 사멸시키기 때문에 고농도의 폐수정화에는 부적합하였다.In addition, the contact treatment method is to break down the organic matter by microorganisms by submerging several strands of microorganism-attached fibers under the surface of the water and then leaving them under water. Also, during high concentration wastewater purification, such as livestock wastewater, manure or food waste It is not suitable for high concentration wastewater purification because foreign substances such as these adhere to the microorganism-attached fibers and kill the microorganisms native to the microorganism-attached fibers.
또, 축산분뇨는 자체에 많은 유기물과 질소, 인, 부유물 등 비료로서 유효한 성분을 많이 포함하고 있음에도 불구하고, 기존의 처리시스템은 고체와 액체의 분리하고, BOD를 낮추는 데에만 목적을 두고 정화장치들이 만들어져 왔기 때문에 자원의 재활용률이 현저하게 떨어지는 문제점을 갖고 있었다.In addition, although livestock manure contains many organic matters and effective ingredients as fertilizers such as nitrogen, phosphorus and suspended solids, the existing treatment system is a purification device for the sole purpose of separating solids and liquids and lowering BOD. Have been made, the recycling rate of resources had a significant drop.
한편, 현재 우리나라의 농토는 화학비료의 과잉사용으로 인해 토양이 산성화되어 농업생산성이 점점 줄어들고, 농작물의 질이 떨어져서 천연비료의 사용이 권장되고 있는데, 기존의 폐수처리 시스템은 페수로부터 분리된 고체를 퇴비화하여천연비로를 생산하는 정도에 불과하였기 때문에 생산량에 한계가 있고, 높은 가격으로 인해 보급에 장애가 있었다.On the other hand, agricultural land in our country is acidified by excessive use of chemical fertilizers, resulting in less agricultural productivity, and the use of natural fertilizers is recommended due to poor quality of crops. Since it was only composted to produce natural fuel furnaces, there was a limit to the production volume, and the high price prevented the supply.
본 발명은 상기와 같은 문제점을 해결하기 위하여 이루어진 것으로, 그 목적은 고농도의 축산폐수를 방류수 기준에 맞추어 정화할 수 있으며, 정화과정 중간 중간에 적정한 농도의 액비를 생산할 수 있는 무독성메디아를 이용한 오폐수와 축산폐수 및 분뇨처리장치를 제공함에 있다.The present invention has been made to solve the above problems, the object of which is to purify the livestock wastewater of high concentration according to the effluent standard, and the wastewater using non-toxic media that can produce a liquid concentration of the appropriate concentration in the middle of the purification process and Livestock wastewater and manure treatment device.

한편, 첨부도면 도3에 도시된 바와 같이 폐수공급탱크(90)로부터 상기 반응조(20)를 직렬 또는 병렬로 연결하고, 그 중간 중간에개폐밸브(V1,V2,V3,V4,V5,V6,V7)와 액비저장탱크(80)(81)를 두어 적정한 농도의 액비를 정화과정 중간에 뽑아내어 사용할 수 있도록 하였다.On the other hand, as shown in Figure 3 attached to the reactor 20 in series or in parallel from the waste water supply tank 90, in the middle of the opening and closing valve (V1, V2, V3, V4, V5, V6, V7) and liquid storage tanks (80, 81) were placed so that the liquid concentration of the proper concentration can be extracted and used in the middle of the purification process.
이하 본 발명에 따른 작용을 첨부된 도면에 의거하여 상세히 설명하면 다음과 같다.Hereinafter, the operation according to the present invention will be described in detail with reference to the accompanying drawings.
첨부도면 도1에 도시된 바와 같이 축산폐수, 분뇨와 같이 고농도(BOD 10000 이상)의 오·폐수가 오·폐수 유입관(21)을 통해 반응조(20) 내부로 유입되면, 반응조(20) 벽면과 반응조 격벽(70)이 이루는 사이의 수중 통로를 통해 하향하면서 반응조(20) 바닥으로 흐르게 된다.As shown in FIG. 1, when the wastewater of high concentration (BOD 10000 or more), such as livestock wastewater and manure, flows into the reaction tank 20 through the wastewater inflow pipe 21, the wall of the reaction tank 20 is shown. And flows to the bottom of the reactor 20 while descending through the underwater passage between the reactor wall 70.
이때 반응조(20) 바닥에 위치된 에어순환장치(40)에 의해 형성된 비교적 큰 공기방울에 의해 물의 유동이 하측에서 상측으로 형성되고 있기 때문에 반응조(20) 내부로 유입된 오·폐수는 그 일부가 반응조(20) 바닥에서 미세기포발생장치(32)의 하측으로 통과하여 수면을 향해 흐르게 되고, 나머지 일부는 안정된 상태에서 미세기포발생장치(32)에 의해 공급되는 산소와 섞이면서 부착미생물 메디아(30)의 하측을 향해 천천히 흐르게 된다.At this time, since the flow of water is formed from the lower side to the upper side by the relatively large air bubbles formed by the air circulation device 40 located at the bottom of the reaction vessel 20, part of the waste water introduced into the reaction vessel 20 is partially At the bottom of the reaction vessel 20, the microbubble generator 32 passes downward and flows toward the water surface, and the remaining part is mixed with oxygen supplied by the microbubble generator 32 in a stable state to adhere to the microorganism media 30. It will flow slowly toward the bottom of the.
이 과정에서 미세기포발생장치(32)에 의해 부착미생물 메디아(30)로 공급되는 오·폐수는 부착미생물 메디아(30)를 통과하면서 부착 미생물에 의해 분해되어 호기성 미생물에 산소를 공급하게 되며, 부착미생물 메디아(30)가 경사지게 설치되어 있기 때문에 미세기포와 오·폐수는 부착미생물 메디아(30)의 저면을 따라 고르게 이동하면서 체류시간이 길어짐과 동시에 미생물 정화작용이 부착미생물 메디아(30) 전체면에 고르게 분포되도록 하는 작용을 하게 된다.In this process, the waste water supplied to the adherent microorganism media 30 by the microbubble generating device 32 is decomposed by the adherent microorganisms while passing through the adherent microorganism media 30 to supply oxygen to the aerobic microorganisms. Since the microorganism media 30 are inclined, the microbubbles and the waste water move evenly along the bottom of the adherent microorganism media 30 to increase the residence time, and at the same time, the microbial purification action is evenly applied to the entire surface of the microorganism media 30. It will act to distribute.
이때 부착미생물 메디아(30)의 주변은 둥그런 형태의 유동이 형성되고 있지만 그 안쪽에는 정채된 상태의 수중반응영역(34)이 형성되면서 미생물에 의한 유기물 분해가 촉진된다.At this time, a circular flow is formed around the adherent microorganism media 30, but the decomposition of organic matter by the microorganism is promoted while the underwater reaction zone 34 is formed inside thereof.
즉, 반응조(20) 내부에 형성된 수중반응영역(34) 주변을 에어순환장치(40)에 의해 오·폐수가 돌면서 순환하기 때문에 수중반응영역(34) 내의 체류시간이 증가하여 정화작용이 촉진되고 동시에 에어순환장치(40)에 의해 순환하는 오·폐수와 수중반응영역(34)에 위치된 미생물간에 고른 접촉과 이동으로 정화효율이 증가하게 된다.That is, since the waste water circulates around the underwater reaction zone 34 formed in the reaction tank 20 by the air circulation device 40, the residence time in the underwater reaction zone 34 is increased, thereby purifying the purification operation. At the same time, the purification efficiency is increased by even contact and movement between the waste water circulated by the air circulation device 40 and the microorganisms located in the underwater reaction zone 34.
한편, 침전조(50) 내부에서 1차적으로 분해가 이루어진 오·폐수는 그 일부가 침전조 분리벽(60)의 중간에 형성된 침전조 유입구(63)를 통해 침전조(50) 내부로 천천히 유입되면서 미처 반응조(20) 내부에서 분해되지 못한 유기물 중 비중이 무거운 유기물은 바닥으로 가라앉아서 침전물을 형성하고, 비중이 가벼운 유기물은 수면위로 떠서 부유물을 형성하게 된다.On the other hand, the waste water, which is primarily decomposed in the sedimentation tank 50, is partially introduced into the sedimentation tank 50 through the sedimentation tank inlet 63 formed in the middle of the sedimentation tank dividing wall 60, and the reaction tank ( 20) Among organics that cannot be decomposed inside, heavy organics sink to the bottom to form sediment, and light organics float on the water to form floats.
이때 침전조 유입구(63)가 도2a에 도시된 바와 같이 지그재그 형태나 도2b에 도시된 바와 같이 주름관 형태로 형성된 경우 오·폐수의 흐름에 저항을 가하게 되어 반응조(20) 내부에서 갖고 있던 오·폐수의 운동에너지 일부가 소멸되면서 안정된 상태로 침전조(50)로 유입된다.At this time, when the sedimentation tank inlet 63 is formed in a zigzag form as shown in FIG. 2A or a corrugated pipe form as shown in FIG. 2B, the sedimentation tank inlet 63 adds resistance to the flow of the wastewater, and thus has the wastewater contained in the reactor 20. As some of the kinetic energy is dissipated is introduced into the settling tank 50 in a stable state.
더욱이 침전조 유입구(63)가 반응조(20)로부터 침전조(50)로 향할수록 하향 경사진 형태를 이루기 때문에 에어순환장치(40)에 의한 영향을 거의 받지 않게 되어 침전조(50) 내는 정적인 상태로 유지된다.Furthermore, since the settling tank inlet 63 is inclined downward from the reaction tank 20 toward the settling tank 50, the settling tank 50 is hardly affected by the air circulation device 40, so that the settling tank 50 remains static. do.
이후 침전조(50)로 유입된 1차 정화된 오·폐수 중의 침전물은 침전조(50)의 코너부위에 설치된 침전물 경사미끄럼판(65)에 의해 바닥에 쌓이지 못하고, 침전조 분리벽(60)과 바닥면이 이루는 침전물 리턴통로(61)를 통해 반응조(20)를 향해 되돌려지면서 반응조(20) 내부에 설치된 에어순환장치(40)에 의해 반응조(20) 내부를 다시 순환하면서 미생물 분해과정을 거치게 되며, 침전조(50) 상단의 부유물 상승부(62)를 통해 수면위로 떠오른 부유물은 침전조 분리벽(60) 상단에 설치된 수류형성판(64)에 의해 일부 안내되는 유동과 물의 유동을 반응조(20)로 되돌리는 부유물 안내판(66)에 의해 반응조(20)의 수면위로 되돌려지면서 수면위를 떠다니다가 오·폐수 유입관(21)에 의한 반응조(20) 내부에서 형성된 하향하는 물살에 이끌려 반응조(20) 바닥으로 가라앉으면서 재분해되는 과정을 거치게 된다.Since the sediment in the first purified waste water introduced into the sedimentation tank 50 is not accumulated on the bottom by the sediment slope sliding plate 65 installed at the corner of the sedimentation tank 50, the sedimentation tank separation wall 60 and the bottom surface This is returned to the reaction tank 20 through the sediment return passage (61) to circulate again inside the reaction tank 20 by the air circulation device 40 installed inside the reaction tank 20, and undergoes a microbial decomposition process, sedimentation tank (50) The float floated on the water surface through the float riser 62 of the upper portion returns the flow and the flow of water partially guided by the water flow forming plate 64 installed on the sedimentation vessel separation wall 60 to the reactor 20. Float on the water while being returned to the water surface of the reaction vessel 20 by the float guide plate 66, and then led to the downward water stream formed inside the reaction vessel 20 by the wastewater inflow pipe 21 to the bottom of the reaction vessel 20. Ash while sitting It is subjected to the process.
그리고, 반응조(20)의 수중에 위치하는 보온파이프(23)는 반응조(20) 내부에서 미생물 분해작용을 촉진시킬 수 있는 적정한 온도로 유지하는 작용을 하게 되며, 더욱이 반응조 내부에 채워진 보온단열재(24)는 외기가 반응조 내부로 전달되는 것을 차단하는 동시에 반응조(20)가 갖고 있는 열이 외부로 방출되는 것을 어느 정도 차단하는 작용을 하게 된다.In addition, the thermal insulation pipe 23 positioned in the water of the reaction vessel 20 serves to maintain an appropriate temperature to promote microbial decomposition in the reaction vessel 20, and further, the thermal insulation material 24 filled in the reaction vessel 20. ) Blocks the outside air from being transferred to the inside of the reactor and at the same time serves to block the heat of the reactor 20 from being released to the outside.
또, 침전조(50)의 중간에 위치된 배출관(22)은 침전물 및 부유물과 분리된 수중의 2차 정화된 오·폐수를 외부로 배출할 수 있게 된다.In addition, the discharge pipe 22 located in the middle of the settling tank 50 can discharge the secondary purified wastewater in the water separated from the sediment and the suspended matter to the outside.
한편, 첨부도면 도3에 도시된 바와 같이 다른 농도의 액비를 하나의 생산설비에서 생산해 내는 경우 폐수처리 과정 중간 중간에 설치된 밸브(V1)(V2)(V3)(V4)(V5)(V6)(V7)를 이용하여 다음 단계로 넘어가는 폐수를 뽑아내서 액비저장탱크(80)(82)에 저장하여 두면 다양한 농도의 액비생산시설로써 활용할 수 있게 된다.On the other hand, as shown in Figure 3, when the liquid ratio of different concentrations produced in one production facility valves (V1) (V2) (V3) (V4) (V5) (V6) installed in the middle of the wastewater treatment process Using the V7 to extract the wastewater to the next stage and stored in the liquid storage tank (80, 82) can be utilized as a liquid fertilizer production facilities of various concentrations.
이상에서 설명한 바와 같은 본 발명은 반응조 내부에 형성된 수중반응영역 주변을 에어순환장치에 의해 오·폐수가 돌면서 순환하도록 하는 구조로 되어 있기 때문에 체류시간이 증가하여 정화작용이 촉진되고 동시에 오·폐수와 미생물간에 고른 접촉으로 정화효율이 증가하며, 축산폐수를 정화하는 과정 중 중간단계에서 적합한 수준의 BOD를 갖는 액비를 뽑아낼 수 있도록 구성되어 있기 때문에 버려지는 자원을 재활용할 수 있는 효과가 있으며, 고농도의 유기성 폐수인 축산폐수 뿐만 아니라 생활오수, 공장폐수, 분뇨 등 다양한 오수 및 폐수를 처리할 수 있는 효과도 있다.As described above, the present invention has a structure that circulates the waste water by circulating the water reaction zone formed in the reaction tank by the air circulation device, so that the residence time is increased and the purifying action is promoted. Purification efficiency is increased by even contact between microorganisms, and because it is configured to extract liquid fertilizers with an appropriate level of BOD in the middle stage of the livestock wastewater purification process, it has the effect of recycling waste resources and high concentration. It is also effective to treat various sewage and wastewater such as domestic wastewater, factory wastewater, and manure as well as animal wastewater which is organic wastewater.
