Description

오수처리용 제트폭기장치{TEH Z-AERATION DEVICE FOR THE SEWAGE DISPOSAL}Jet aeration device for sewage treatment {TEH Z-AERATION DEVICE FOR THE SEWAGE DISPOSAL}

본 고안은 호기성 생물 공정을 이용한 폭기장치의 개량고안으로서, 특히 폭기조 내에 유입되는 오수를 제트폭기 노즐을 통해 반복 순환시킴과 동시에 질산화에 필요한 충분한 용존산소를 다량 공급하여 공기의 수중용해률을 극대화 시키므로 오수의 정화효율을 보다 향상시켜 줄수 있도록 한 오수처리용 제트폭기장치에 관한것이다.The present invention is an improvement plan of aeration apparatus using aerobic biological process, and in particular, it repeatedly circulates the sewage introduced into the aeration tank through the jet aeration nozzle and maximizes the water dissolution rate of air by supplying a large amount of dissolved oxygen necessary for nitrification. The present invention relates to a sewage treatment jet aeration device that can further improve the purification efficiency of sewage.

통상 사용되는 호기성 생물 공정을 이용한 폭기장치는 일정한 원통의 폭기조 내에 다수개의 격판을 설치하고 그 내에 호기성 생물을 저장 한 다음 폭기조 하부에서 산기관을 통하여 공기를 반복적으로 공급하여 호기성 생물과 오수가 공기에 상호 접촉하여 정화작업이 수행토록 하고 있다.The aeration system using aerobic bioprocesses, which are commonly used, installs a plurality of diaphragms in a fixed aeration tank, stores aerobic organisms therein, and then repeatedly supplies air through the diffuser at the bottom of the aeration tank. The purge is performed in contact with each other.

그러나 위와 같은 종래의 폭기장치는 폭기조 내에 다량의 오수를 저장한 다음 폭기조 하부에서 공기를 주입하는 방법을 사용하고 있어, 투입된 공기의 일부 2 - 3% 정도만이 수중에 용해되어 미생물의 유기물 분해에 이용되고 나머지 97 - 98%의 공기는 수면으로 부상하여 대기중에 날아가 버리는 폐단을 가지게 된다.However, the conventional aeration device as described above uses a method of storing a large amount of sewage in the aeration tank and then injecting air from the bottom of the aeration tank, so that only about 2 to 3% of the injected air is dissolved in water and used to decompose microorganisms. The remaining 97-98% of the air rises to the surface, leaving the lungs flying away into the atmosphere.

이는 호기성 생물 공정을 이용한 오수처리방법은 다량의 공기를 오수와 호기성 생물에 접촉시켜 정화작업을 실시케 하는 것인데, 위의 경우 단순히 폭기조 내에 오수를 저장 한 상태로 공기를 주입하는 것으로 대부분의 공기가 자연적으로 수면에 부상하여 대기중으로 날아가 버리므로, 오수와 호기성생물에 공기가 충분히 접촉을 갖지 못하여 정화 효율이 매우 떨어지는 폐단을 가지고 있었던 것이다.The sewage treatment method using aerobic biological process is to contact a large amount of air to the sewage and aerobic organisms to purify. In this case, the air is simply injected into the aeration tank with the waste water stored. Naturally, the surface of the water rises to the air, so that the waste water and aerobic organisms do not have enough contact with the air, so the purification efficiency was very poor.

따라서 본 고안은 상기와 같은 종래의 제반 문제를 해소하기 위하여 안출된 것으로서 특히, 폭기조내의 오수가 제트폭기노즐을 통해 공기와 함께 반복순환될수 있도록 하여 공기와의 마찰률을 높여 주고 또 폭기조 내에 다수개의 파공판을 설치하여 공기의 수중용해률을 극대화 시키므로 오수의 정화효율을 보다 향상시켜 줄수 있도록 함에 그 기술적 과제를 가지는 것이다.Therefore, the present invention has been devised to solve the conventional problems as described above. In particular, the sewage in the aeration tank can be repeatedly circulated with the air through the jet aeration nozzle, thereby increasing the friction rate with the air and a plurality of aeration tanks. By installing the perforated plate to maximize the water dissolution rate of the air is to have the technical problem to improve the purification efficiency of sewage more.

본 고안은 상부 양측으로 오수투입부(25)와 배출부(24)가 각각 마련되는 통상의 폭기조(22)에 있어서,The present invention is in the conventional aeration tank 22 is provided with a sewage input portion 25 and the discharge portion 24 on both sides of the upper,

상기 폭기조(22) 내부 양측에 각각 하측이 연통된 격벽(23)을 설치하여 수위상승에 따른 오수의 배출이 이루어지는 침전실(21)을 구성하고, 그 내측 중앙부로는 하측부가 밀폐된 폭기실(2)을 별도 구성하여 그 내에 상부로 에어펌프(12)의 에어분사관(11)이 관통설치되어 있는 제트폭기노즐(1)을 내설하여 상기 폭기조(22) 하단부와 펌프(31)가 설치된 연결관(3)으로 상호 연결구성되게 하되, 상기 폭기실 (2)내에는 제트폭기노즐(1)과 동일 선상이 되게 그 하측부로 다수개의 파공판(13)을 설치하여서 된 구조이다.A partition 23 having lower sides communicating with both sides of the aeration tank 22 constitutes a sedimentation chamber 21 in which wastewater is discharged according to an increase in water level, and an inner central portion of the aeration chamber 22 has a lower sealed portion. 2) separately configured to internally install the jet aeration nozzle (1) through which the air injection pipe 11 of the air pump 12 is installed in the upper part of the aeration tank 22, the lower end connection and the pump 31 is installed The pipe 3 is connected to each other, and the aeration chamber 2 has a structure in which a plurality of perforated plates 13 are installed at the lower side thereof in the same line as the jet aeration nozzle 1.

이상과 같이 구성된 본 고안의 작용을 첨부된 도면과 함께 보다 상세히 설명하자면 먼저 첨부된 도면 도 1 과 같이 폭기조(22) 내에 다량의 호기성생물을 충진 시킨 다음 오수투입부(25)를 통해 적정량의 오수를 폭기조(22) 내로 투입하여 상기 호기성 생물과 희석시키고 이를 다시 폭기조(22) 하단부에 연결설치된 연결관(3)을 통해 제트폭기노즐(1)로 유입시켜 공기와 함께 폭기조(22) 내로 분사되게 하므로 오수와 미생물이 공기에 충분히 접촉될수 있도록 하였다.Referring to the operation of the present invention configured as described above in more detail with reference to the accompanying drawings, as shown in Figure 1 attached a large amount of aerobic organisms in the aeration tank 22 and then the appropriate amount of sewage through the sewage input unit 25 Into the aeration tank 22 to dilute with the aerobic organism and inject it into the jet aeration nozzle 1 through a connecting pipe 3 installed at the lower end of the aeration tank 22 to be injected into the aeration tank 22 together with the air. Therefore, the sewage and microorganisms can be sufficiently in contact with the air.

이를 보다 구체적으로 설명하자면, 첨부된 도면 도 1 에서 처럼 오수의 정화 작업을 실시할 경우 상기 제트폭기노즐(1)의 에어분사관(11)으로 강한 공기를 주입시켜 폭기실(2)내의 오수를 파공판(13) 외주연으로 와류현상을 일으키게 하므로 공기와의 접촉률을 상승시키고 또 강하게 주입되는 공기를 다수개의 파공판(13)에 부딧치게 하여 공기방울이 부서져 오수속에 보다 용이하게 용해될수 있도록 하였다.More specifically, when the wastewater purification operation is performed as shown in FIG. 1 of the accompanying drawings, strong air is injected into the air injection pipe 11 of the jet aeration nozzle 1 to discharge the sewage in the aeration chamber 2. Due to the vortex phenomenon caused by the outer periphery of the perforated plate 13, the contact rate with the air is increased, and the strongly injected air is buried in the plurality of the perforated plates 13 so that the air bubbles are broken so that they can be more easily dissolved in the wastewater.

그리고 상기 폭기실(2)에서 제트분사노즐(1)에 의하여 1차적으로 정화된 오수는 계속하여 투입되어지는 오수의 수위 상승으로 인해 그 외측의 침전실(21)로 자연 이송되어 지는데 이때 상기 정화가 완료된 오수는 폭기조(22) 양측의 배출부(24)로 수위상승에 따른 자연배출이 실시되고 반대로 정화가 완벽하게 이루어지지 못한 오수는 그 무게에 의하여 침전실(21) 바닥부로 가라앉아 폭기조(22) 하단에 설치된 연결관(3)을 통해 상기 제트폭기노즐(1)과 폭기조(22)를 반복 순환되게 하므로 다량의 공기 주입과 오수의 순환으로 인해 용존산소량이 극대화 되면서 정화효율이 상승하게 되는 것이다.In addition, the sewage purified primarily by the jet spray nozzle 1 in the aeration chamber 2 is naturally transported to the sedimentation chamber 21 outside of the sewage due to an increase in the level of the sewage introduced continuously. Completed sewage is discharged to the aeration tank 22 on both sides of the aeration tank 22, the natural discharge is carried out according to the rise in the water level, on the contrary, the sewage that is not completely purified by the weight sinks to the bottom of the settling chamber 21 by the weight of the aeration tank ( 22) Since the jet aeration nozzle 1 and the aeration tank 22 are repeatedly circulated through the connection pipe 3 installed at the bottom, the purification efficiency is increased while maximizing the dissolved oxygen amount due to the large amount of air injection and the circulation of the sewage. will be.

이상에서 살펴본 바와 같이 본 고안은 오수를 폭기실과 침전실 그리고 제트폭기노즐을 통해 계속해서 순환될수 있게 함은 물론 폭기조 내로 공기를 계속하여 오수와 함께 분사 되게 하므로 오수와 호기성 생물들이 공기에 접촉이 충분히 이루어 질수 있도록 하고 또 제트폭기노즐을 통해 강하게 주입되는 공기로 폭기실내의 오수를 회전시킴과 동시에 다량으로 투입되는 공기를 파공판에 부딧치게 하여 충분한 량의 용존산소량으로 정화효율을 극대화 시켜 줄수 있는 장점을 가지는 것이다.As described above, the present invention not only allows the waste water to be continuously circulated through the aeration chamber, the sedimentation chamber and the jet aeration nozzle, but also continuously injects the air into the aeration tank with the waste water, so that the sewage and aerobic organisms have sufficient contact with the air. It is possible to maximize the purification efficiency with sufficient dissolved oxygen by rotating the sewage in the aeration chamber with the air injected strongly through the jet aeration nozzle and allowing a large amount of air to be injected into the perforated plate. To have.
