바실러스 종 혼합균에 의한 하·폐수정화처리장치Sewage / Wastewater Purification System by Bacillus Species

본 고안은 바실러스 종 혼합균에 의한 하·폐수 정화처리장치에 관한 것으로서, 비니리덴 크로라이드계 섬유를 특수망상구조로 만든 회전미생물접촉체에 바실러스 종 혼합균을 부착시켜 성장케한 후 폭기조에서 바실러스 종 혼합균을 활성화하는 조건으로서 공급되는 전체공기량을 3실로 구분된 폭기조 제1실에 60%이상을, 그 나머지를 폭기조 제2실, 폭기조 제3실 및 회전미생물접촉조에 미리 조정된 비율에 따라 점감폭기가 되도록 하며, 바실러스 종 혼합균의 성장에 필요한 무기성활성제를 적당량 투입하고, 폭기조 제3실에서 회전미생물접촉조 쪽으로 포자화된 폭기액을 가변적으로 순환이 이루어지도록 하며, 폭기조 제1실에는 침전지에 침전된 슬러지의 일부를 반송시켜 바실러스 종 혼합균의 농도를 일정하게 유지토록 하는데, 이러한 조건이 되면 바실러스 종 혼합균은 사상균체화 → 포자 → 발아 → 사상균체화의 생활환이 이루어지는 과정에서 기하급수적으로 분열·성장을 계속하여 고농도의 혼합균체로 우점배양됨으로서 하·폐수중에 함유되어 있는 유기물 및 영양염류인 질소·인 등이 다량으로 섭취되므로서 정화되어 깨끗한 물로 바뀌고, 또한 처리과정에서 발생되는 악취들은 바실러스 종 혼합균에 의하여 섭취되어 제거되므로 별도의 탈취설비가 필요없으며, 침전지에서는 고·액분리가 잘될뿐만 아니라, 슬러지 발생량이 현저하게 감소되는 등의 탈수효율이 뛰어나 처분할 슬러지 케이크량도 적어 그에따른 처리비용이 감소하는 바실러스 종 혼합균에 의한 하·폐수 정화처리장치에 관한 것이다.The present invention relates to a sewage and wastewater treatment apparatus using mixed Bacillus spp., Which is made by attaching Bacillus spp. Mixed bacteria to a rotating microbial contact body made of a special network structure of vinylidene chromide-based fiber, and then in the aeration tank. As a condition for activating the species mixed bacteria, the total amount of air supplied is 60% or more in the first aeration tank divided into three chambers, and the rest is pre-adjusted to the second aeration chamber, the third aeration tank and the rotating microbial contact tank. Attenuated aeration, the appropriate amount of inorganic activator required for the growth of Bacillus species mixed bacteria, and the aeration of the spores aerated spores from the third chamber to the rotary microbial contact tank to the variable circulation, the first aeration tank In order to maintain a constant concentration of Bacillus species mixed bacteria by returning a part of the sludge deposited in the sedimentation basin, Bacillus spp. Is mixed with filamentous cells → spores → germination → filamentous fungi, and continues to divide and grow exponentially and predominantly grow into mixed cells of high concentration. Nitrogen, organic matter and nutrients contained in sewage and wastewater Phosphorous is ingested in large quantities to be purified and replaced with clean water. Also, odors generated during the treatment are ingested and removed by mixed Bacillus species, so no separate deodorization equipment is required. In addition, the present invention relates to a sewage and wastewater purification apparatus using Bacillus sp. Mixed bacteria, which is excellent in dehydration efficiency such as a significant reduction in sludge generation, and thus a small amount of sludge cake to be disposed of, thereby reducing the treatment cost.

일반적으로 하·폐수 정화처리장치에 관한 기술은 1976년 국내 최초로 건설된 청계천 하수처리장에서부터 현재에 이르기까지 전국에 건설된 하수처리장 및 폐수처리장들의 대부분은 표준활성슬러지기술 및 그 응용기술로서 유기물과 부유물질만을 제거한 후 방류시킬뿐 부영양화 및 적조현상의 원인이 되는 질소 및 인의 제거는 이루어지지 않았다. 이에 대해 정부에서는 1996년 1월 1일부터 수질방류기준에 질소 및 인을 제거할 수 있는 적합한 시설을 갖추도록 하였는 바, 그러나 국내기술로서는 해결할 수 없어 선진해외기술인 A/O, A2/O, VIP,Bardenpho, UCT, SBR 등을 도입하여 건설을 하고 있는데, 이들 기술의 원리는 모두 질소를 질산화 시킨후 무산소상태에서 탈기하는 방법으로서 질소를 제거하며, 인은 혐기성 상태를 만들어 인의 방출을 늘린다음 호기성상태로 전환시켜 미생물이 인을 과잉섭취케한 다음 그 슬러지를 처리하는 기술이다. 그러나, 이들의 기술들은 질소 및 인의 제거효율이 60 ∼ 70% 정도이며, 수온, 수질 및 수량 변동에 민감하여 안정된 수질을 얻을 수 없다. 또한 질소를 질산화시키는데 엄청난 동력이 소요될뿐만 아니라 공정이 복잡하여 시설의 운전에 고도의 기술을 요한다. 그리고, 각 공정에서 발생되는 악취를 제거하기 위한 시설을 별도로 설치해야 하며, 시설의 부식이 강하여 수명이 짧고, 이에대한 시설의 유지비도 많이드는 등의 여러 문제점이 내재되어 있었다.In general, most of the sewage and wastewater treatment plants constructed nationwide from Cheonggyecheon sewage treatment plant, which was first constructed in 1976 to the present, are standard activated sludge technology and applied technologies. Only the material was removed and then discharged, but nitrogen and phosphorus, which caused eutrophication and red tide, were not removed. In contrast, in the government can not solve as a bar, but domestic technology hayeotneun from January 1, 1996 to be equipped with the appropriate facilities to remove nitrogen and phosphorus in the water discharge based on advanced foreign technology, A / O, A 2 / O , It is constructed by introducing VIP, Bardenpho, UCT, SBR, etc. The principle of all these technologies is to nitrate nitrogen and then degas in anoxic state to remove nitrogen, and phosphorus makes anaerobic state to increase phosphorus release. It is a technique to convert the sludge to an aerobic state by causing the microorganism to ingest excessive phosphorus. However, these techniques have a nitrogen and phosphorus removal efficiency of about 60 to 70%, and are sensitive to fluctuations in water temperature, water quality and yield, and thus cannot obtain stable water quality. In addition to the tremendous power required to nitrate nitrogen, the process is complex and requires high technology to operate the facility. In addition, it is necessary to install a separate facility for removing odor generated in each process, the corrosion of the facility is strong, there is a lot of problems, such as short life, high maintenance costs for the facility.

본 고안은 종래의 표준활성화 슬러지기술 및 그 응용기술 등이 처리하지 못한 질소 및 인의 제거와 최근 도입되고 있는 선진해외기술인 질소 및 인 제거기술의 복잡한 공정·고가의 시설비 및 시설유지비가 많이 소요되는데 비하여 제거효율은 기대할 정도가 못되므로 이러한 점을 보완하여 유기물 및 부유물질 제거는 물론 질소 및 인까지도 경제적이고 효율적으로 제거하고, 또한 각 처리과정에서 발생하는 각가지 악취물질을 제거하는 탈취설비에 대한 대책도 해결하며, 특히 유기성산업폐수, 가정하수, 분뇨 및 축산폐수처리 등에 탁훨한 바실러스 종 혼합균에 의한 하·폐수정화처리장치를 제공하는데에 그 목적이 있다.The present invention requires a lot of complicated process and expensive facility and facility maintenance costs of nitrogen and phosphorus removal technology which is not processed by conventional standard activated sludge technology and its application technology, and nitrogen and phosphorus removal technology, which are recently introduced overseas technology. As the removal efficiency is not as expected, it is necessary to supplement these points to economically and efficiently remove not only organic matter and suspended solids, but also nitrogen and phosphorus, as well as countermeasures for deodorization facilities that remove various odorous substances generated in each treatment process. The present invention aims to provide a sewage and wastewater purification apparatus by mixing Bacillus spp. Which is excellent for organic industrial wastewater, home sewage, manure and livestock wastewater treatment.

상기 목적을 달성하기 위하여 본 고안의 장치는 유기성산업폐수, 가정하수, 분뇨 및 축산폐수를 정화처리함에 있어서, 비니리덴 크로라이드계 섬유를 특수망상구조로 만든 회전미생물접촉체에 바실러스 종 혼합균을 부착시켜 성장케 하는 회전미생물접촉조와 폭기조를 연계시켜 공기를 공급하면서 하·폐수를 처리하되, 상기 폭기조에 들어가는 전체공기량의 60∼70%를 폭기조 제1실에 공급하고 나머지 20∼ 30%의 공기는 폭기조 제2실 및 폭기조 제3실에 각각 공급하고 약 5%정도는 상기 회전미생물접촉조에 분할 공급하도록 된 특징이 있다.In order to achieve the above object, the device of the present invention, in the treatment of organic industrial wastewater, household sewage, manure and livestock wastewater, Bacillus species mixed bacteria in a rotating microbial contact made of a special network structure Process the sewage and wastewater while supplying air by connecting the microbial contact tank, which is attached to grow, and the aeration tank, and supplies 60-70% of the total air volume entering the aeration tank to the first aeration chamber and the remaining 20-30% of air. Is supplied to the aeration chamber second chamber and the aeration tank third chamber, respectively, and about 5% is characterized in that divided supply to the rotary microbial contact tank.

또, 본 고안의 다른 특징으로 상기 회전미생물접촉조는 생물화학적산소요구량(BOD)의 부하에 따라 대수가 결정되며, 병렬로 설치되도록 함에 있다.In another aspect of the present invention, the rotary microbial contact tank has a log number determined according to the load of biochemical oxygen demand (BOD), and is to be installed in parallel.

또한, 도1에 의하면 유량조정조(5)와 유량분배조(11) 사이에 세목스크린(9)를 설치하여 원수중에 함유되어 있는 미세한 부유물질까지 제거시킨후 회전미생물접촉조(13)에 정량적으로 이송할 수 있도록 구성되어 있다. 회전미생물접촉조(13)에서는 미생물접촉체가 회전되면서 조안의 유입 하·폐수속의 침적상태와 대기중에 있어서의 공기의 공급을 교대로 반복하면서 왕성한 미생물의 생육을 도모하도록 구성되어 있다.1, a fine screen 9 is installed between the flow rate adjustment tank 5 and the flow rate distribution tank 11 to remove fine suspended substances contained in the raw water, and then quantitatively in the rotating microbial contact tank 13. It is configured to be transported. The rotary microbial contact tank 13 is configured to grow vigorous microorganisms while the microbial contact is rotated to alternately repeat the deposition state of the inflow and outflow into the tank and the supply of air to the atmosphere.

상술한 본 고안에 의한 것은 유량과 수질에 의하여 산정된 대수만큼을 병렬로 배치한 제1회전미생물접촉조(13a)와 제2회전미생물접촉조(13b)의 다공조직체로 구성된 회전미생물접촉조(13)에서 망상으로 접착형성된 균상체를 접촉조중에서 4-8rpm 정도로 회전시키면 균상체에 바실러스 종 혼합균이 부착하여 대수성장을 하면서 고밀도화되어 연속적으로 유입되는 하·폐수중에 함유된 오염물질을 흡착분해하는 장치이다.According to the present invention described above is a rotary microbial contact tank consisting of a porous structure of the first rotary microbial contact tank 13a and the second rotary microbial contact tank 13b arranged in parallel by the number calculated by the flow rate and the water quality ( 13) Rotating the fungus body formed into a mesh in the contact tank at 4-8rpm, adsorbing and decomposing contaminants contained in the sewage and wastewater, which are densified and continuously inflowed while adhering Bacillus species to the fungus body. Device.

균상체가 특수망상구조이므로 부착된 바실러스 종 혼합균에 대한 산소공급능력이 탁훨하기 때문에 단위 용적당 아주 높은 유기물부하를 감당할 수 있다.Since the fungus has a special network structure, the oxygen supply ability to the attached Bacillus species mixed bacteria is excellent, so that the organic load can be very high per unit volume.

회전미생물접촉조(13)을 거친 처리수는 폭기조 제1실(18a)에서 바실러스 종 혼합균은 가장 왕성하게 증식되면서 유기물 및 영양염류를 최대한으로 섭취하여 영양원으로 이용되면서 깨끗한 물로 정화된 후 폭기조 제2실(18b)로 유입된다.The treated water passing through the rotary microbial contact tank 13 is the most vigorous growth of Bacillus species in the first chamber 18a of the aeration tank, while maximizing the intake of organic matter and nutrients and using it as a nutrient source to purify it with clean water. It flows into two chambers 18b.

상기 폭기조 제2실(18b)에서는 성장 및 증식이 필요한 유기물 및 영양염류가 갑자기 부족한 빈 영양상태로 전환되는 중간과정으로서 바실러스 종 혼합균은 자신의 생존을 위하여 포자를 형성할 준비를 한다. 즉, 막대세포로 이어진 실모양의 사상체들은 악조건하에서 강한 저항성을 가지는 세포 1개당 1개의 포자를 형성하기 시작하는데, 이때 용존산소가 존재하면 포자형성이 늦어지므로 공기공급량을 급격히 줄여 용존산소를 0.1mg/ι이하가 되도록 조절한다. 이 단계가 포자화가 되기 위한 준비단계이다.In the second chamber 18b of the aeration tank, the Bacillus sp. Mixed bacterium prepares to form spores for its own survival as an intermediate process in which the organic matter and nutrients that need growth and proliferation are suddenly switched to an empty nutrition state. In other words, the filamentous filaments that lead to rod cells start to form one spore per cell having strong resistance under adverse conditions. If dissolved oxygen is present, spore formation is slowed down, so the air supply is sharply reduced to decrease the dissolved oxygen by 0.1 mg. Adjust to be less than / ι. This is the preparation stage for sporeing.

다음은 폭기조 제3실(18c)에서는 슬러지가 침강되지 않을 정도만큼의 공기를 공급하면서 바실러스 종 혼합균에 대하여 최악의 생활환경을 조성하므로서 남아있는 사상체를 모두 포자화시킨다. 그런데 포자화 과정에서 특이할만한 현상이 일어나는데, 포자화가 되면서 포자주변에 점착물질이 생성되어 포자가 서로 엉켜 붙으면서 주위의 부유물질 등을 함께 부착시켜 응집덩어리가 점점 커지면서 비중도 늘어나므로 다음공정인 침전지(23)에서 고·액분리가 뚜렷하게 이루어진다.Next, the aeration tank third chamber 18c spores all remaining filaments by creating the worst living environment for the Bacillus species mixed bacteria while supplying enough air so that the sludge does not settle. However, a peculiar phenomenon occurs during the sporulation process. As spores are formed, an adhesive substance is formed around the spores, and spores are entangled with each other, and the surrounding suspended solids are attached together to increase the cohesive mass and the specific gravity increases. In (23), solid-liquid separation occurs clearly.

또한, 폭기조 제3실(18C)에서는 회전미생물접촉조(13)에서 유실되는 바실러스 종 혼합균의 보충을 위하여 폭기액순환펌프(20)로서 유량분배조(11)로 유입량 대비 50∼200% 정도를 가변적으로 계속 보낸다. 이렇게 함으로써 망상구조에 부착된 바실러스 종 혼합균의 농도를 일정하게 유지시켜 줄 수 있다.In addition, the aeration tank third chamber (18C) is about 50 to 200% of the flow rate into the flow distribution tank (11) as the aeration liquid circulation pump (20) for replenishing Bacillus species mixed bacteria lost in the rotary microbial contact tank (13). Continue to send variably. By doing so, the concentration of the Bacillus species mixed bacteria adhered to the network structure can be kept constant.

포자화되면서 형성된 응집덩어리인 슬러지는 침전조(23)로 유입되면서 빠르게 고·액이 분리되며 상징액은 방류조(30)을 거쳐 방류관(31)을 통해 방류되고, 침강된 슬러지중 일부는 반송슬러지펌프(24)에 의하여 계량조(16)로 유입량 대비 50∼200%정도를 가변적으로 계속 보내는데, 이는 폭기조 제1실(18a)에서의 바실러스 종 혼합균을 107- 1011개/mι정도로 고농도를 유지시켜야만 안정된 처리를 계속할 수 있기 때문이며, 나머지 슬러지는 잉여슬러지펌프(26)에 의하여 슬러지농축조(28)로 이송되어 농축된 후 별도의 탈수설비에 의하여 처리된다.Sludge, which is agglomerated mass formed as spores, flows into the settling tank 23, and the solid and liquid are quickly separated, and the supernatant is discharged through the discharge pipe 31 through the discharge tank 30, and some of the settled sludge is returned to the sludge. The pump 24 continuously sends about 50-200% of the inflow rate to the metering tank 16, which is a high concentration of 10 7-10 11 / mι of Bacillus species mixed in the first chamber 18a of the aeration tank. This is because only a stable treatment can be continued, and the remaining sludge is transferred to the sludge concentration tank 28 by the excess sludge pump 26, concentrated and processed by a separate dehydration facility.

이와같이 본 고안 특수망상구조로 형성된 회전미생물접촉조와 폭기조로 구성된 하.폐수정화처리장치는 처리해야할 하.폐수를 차례로 유입시켜 회전미생물접촉체에 부착된 바실러스 종 혼합균과 접촉케 하므로서 일차 처리되고 미처리된 오염물질은 폭기조(18)에서 완벽하게 제거시키고, 또 특수망상구조로 형성된 회전미생물접촉조(13)는 폐수와 대기중을 회전하면서 산소를 공급받으며, 회전미생물접촉조(13)내의 부유물질 침적을 방지하기 위하여 소량의 공기를 주입하고, 3개의 실로 구성된 폭기조(18)에 공급되는 전체공기량의 60∼70%는 폭기조 제1실(18a)에 공급하고, 폭기조 제2실(18b)에는 20%정도를 남는 공기는 폭기조 제3실(18c)과 회전미생물접촉조(13)에 공급하고, 폭기액의 순환은 폭기조 제3실(18c)에서 유량분배조(11)로 유입량대비 50∼200%를 가변적으로 실시하며, 침전지(23)에서 계량조(16)로 슬러지를 유입량대비 50∼200%를 가변적으로 반송하는 것을 특징으로 한다.Thus, the sewage and wastewater purification treatment device composed of the rotating microbial contact tank and the aeration tank formed by the special network structure of the present invention is first treated and untreated by inflowing the wastewater to be treated, in contact with the Bacillus species mixed bacteria attached to the rotating microbial contact. The contaminant is completely removed from the aeration tank 18, and the rotary microbial contact tank 13 formed of a special network structure receives oxygen while rotating the wastewater and the atmosphere, and the suspended matter in the rotary microbial contact tank 13 In order to prevent deposition, a small amount of air is injected, and 60 to 70% of the total amount of air supplied to the aeration tank 18 composed of three chambers is supplied to the aeration tank first chamber 18a, and to the aeration tank second chamber 18b. About 20% of the remaining air is supplied to the aeration tank third chamber 18c and the rotary microbial contact tank 13, and the circulation of the aeration liquid is 50 to the flow rate of the inflow into the flow distribution tank 11 from the aeration tank third chamber 18c. Variable 200% Carried out, and to the sludge to the weighing tank 16 in the settling tank (23) characterized in that the variable conveying the contrast 50-200% inflow.

이상 상술한 바와 같이 본 고안에 의한 처리는 각종 시설 또는 가정 등에서 배출되는 하·폐수에 바실러스 종 혼합균을 접종하여 배양·증식시키면 함유된 오염물질인 유기물, 질소 및 인 등을 효과적으로 제거시킴과 더불어 발생되는 악취도 제거되는 장치로서 환경측면에서 보면 그 효과는 지대한 고안이라고 볼 수 있으며, 경제적인 측면으로도 유용한 고안이다.As described above, the treatment according to the present invention inoculates Bacillus sp. Mixed bacteria into sewage and wastewater discharged from various facilities or homes to incubate and multiply to effectively remove organic substances, nitrogen and phosphorus, etc., which are contained. It is a device that removes the odor that is generated. In terms of environment, the effect can be seen as a great design, and it is also a useful design for the economic aspect.
