수처리시스템용 폭기장치{Aeration apparatus for wastewater treatment system}Aeration apparatus for wastewater treatment system

본 발명은 수처리시스템용 폭기장치에 관한 것으로, 보다 상세하게는 폐수, 하수 및 오수 등이 유입되는 집수조의 상층수를 펌핑하고 하층으로 분사시켜 집수조의 저면에 고형물이 침전되는 것을 억제하고 상층수가 하층으로 분사시 일정한 온도의 외부 공기가 함께 공급되어 폐수, 하수 및 오수 등이 대류되도록 하고 산소를 이용한 수처리 효율이 향상되도록 할 수 있는 수처리시스템용 폭기장치에 관한 것이다. The present invention relates to an aeration device for a water treatment system, and more particularly, by pumping and spraying the upper layer water of a water collecting tank into which wastewater, sewage and sewage water flows into the lower layer to suppress sedimentation of solids on the bottom surface of the water collecting tank and preventing the upper layer water from being deposited in the lower layer It relates to an aeration device for a water treatment system capable of convection of wastewater, sewage, sewage, etc. by supplying external air at a constant temperature during spraying and improving the efficiency of water treatment using oxygen.

급속한 인구의 증가 현상과 고도의 산업 발달의 이면에서 인간의 생존 활동으로 인한 다종, 대량의 폐기물은 시간이 지날수록 심각하게 환경을 오염시키고 있으며, 그 결과 환경 정화 문제는 우리 스스로 해결하지 않으면 안 되는 매우 중대한 당면 과제가 되고 있다.Behind the rapid population growth and advanced industrial development, various types and large amounts of waste from human survival activities are seriously polluting the environment as time goes by, and as a result, we have to solve the environmental cleanup problem ourselves. It is becoming a very serious challenge.

현 시점의 환경 문제 중에서 고농도 유기성 폐수, 하수 및 오수(이하, 폐수라 함)의 영양염류(질소 및 인)로 인한 수질 오염은 수계는 물론 인간에게 커다란 문제를 초래하게 되었다. Among the current environmental problems, water pollution caused by nutrients (nitrogen and phosphorus) in high-concentration organic wastewater, sewage, and sewage (hereinafter referred to as wastewater) has caused great problems not only in the aquatic system but also in humans.

이에, 질소 및 인과 같은 영양염류를 제거하는 수처리시스템은 내외에서 많이 개발되고 있다.Accordingly, a water treatment system for removing nutrients such as nitrogen and phosphorus has been widely developed both inside and outside the country.

종래의 수처리시스템은, 폐수가 유입되는 집수조와, 집수조를 거친 폐수가 유입되며 고형물을 침전시킴으로써 고액분리하는 제1침전조와, 제1침전조를 거친 폐수가 유입되는 BRD조(140)와, BRD조를 거친 폐수가 유입되며 고형물을 침전시킴으로써 고액분리하는 제2침전조와, 제2침전조와 관로로 연결되는 탈질조 등을 포함하고, 산소가 공급되지 않는 무산소 또는 혐기성 반응조의 구성을 통해서는 질산성 질소를 질소 가스로 환원하여 대기 중으로 방출시키고 활성 슬러지로부터 인의 방출을 유도하며, 산소가 공급되는 호기성 반응조의 구성을 통해서는 유기질소 또는 암모니아성 질소를 질산성 질소로 전환시켜 질소와 인을 제거하고 있다.The conventional water treatment system includes a water collecting tank into which wastewater flows, a first settling tank in which wastewater passing through the water collecting tank flows in and solid-liquid separation by precipitating solids, a BRD tank 140 into which wastewater passing through the first settling tank flows, and a BRD tank The wastewater that has passed through the inflow includes a second sedimentation tank that separates solid-liquid by precipitating solids, and a denitrification tank connected to the second settling tank by a pipe. is reduced to nitrogen gas, released into the atmosphere, phosphorus is released from activated sludge, and nitrogen and phosphorus are removed by converting organic nitrogen or ammonia nitrogen into nitrate nitrogen through the configuration of an aerobic reactor in which oxygen is supplied. .

그러나 종래의 수처리시스템은, 집수조 또는 집수조에서 탈질이 진행된 폐수가 분배조에 일정량 유입 저장된 후 제1침전조로 분배되는 구성을 가지고 있다.However, the conventional water treatment system has a configuration in which a predetermined amount of wastewater denitrified in the water collecting tank or the water collecting tank is introduced and stored in the distribution tank and then distributed to the first settling tank.

이에, 집수조 또는 분배조에 유입된 폐수는 고형물인 영양염류를 포함하고 있기 때문에, 반응조에 장시간 저장시 고형물이 무게에 의해 반응조의 하부에 퇴적되거나 그 상태로 제1침전조로 공급되어 폐수 공급관 내부에 퇴적되어 수처리 효율이 크게 저하되는 문제점이 있다.Therefore, since the wastewater introduced into the water collecting tank or distribution tank contains nutrients as solids, the solids are deposited in the lower part of the reaction tank due to their weight when stored for a long time in the reaction tank, or are supplied to the first settling tank in that state and are deposited inside the wastewater supply pipe. There is a problem in that the water treatment efficiency is greatly reduced.

또한, 집수조나 분배조에 일정량 이상으로 폐수가 저장된 후에 제1침전조로 분배되는 구성을 가지고 있기 때문에, 겨울철 등에는 정체 상태의 폐수가 결빙되어 제1침전조로 공급되지 않아 수처리 효율이 크게 저하되는 문제점이 있다.In addition, since it has a configuration in which wastewater is stored in a water collecting tank or a distribution tank in excess of a certain amount and then distributed to the first settling tank, in winter, stagnant wastewater is frozen and not supplied to the first settling tank, resulting in a significant decrease in water treatment efficiency. have.

또한, 집수조나 분배조가 호기성 반응조로 작동되는 경우 반응조의 내부에 산소를 공급하는 폭기장치가 구성되지만 대부분 반응조의 하층수에만 산소를 공급하는 구조를 가지기 때문에, 반응조의 상층수에는 산소가 부족하여 호기성 반응조로서의 수처리 효율이 크게 저하되는 문제점이 있다. In addition, when the water collecting tank or the distribution tank is operated as an aerobic reactor, an aeration device for supplying oxygen to the inside of the reaction tank is configured, but most of them have a structure that supplies oxygen only to the lower layer water of the reaction tank. There is a problem in that the water treatment efficiency as a reaction tank is greatly reduced.

도 1 내지 도 5에 도시된 같이, 본 발명에 따른 수처리시스템용 폭기장치(500)는, 수처리시스템의 반응조 중 폐수가 유입되는 호기성 반응조 등과 같은 집수조(110)의 상측부에 구성되는 베이스부(510), 베이스부(510)로부터 집수조(110)의 하층 수위까지 구성되고 집수조(110)의 상층 수위나 중층 수위의 폐수가 펌핑된 후 집수조(110)의 하층 수위에 분사되도록 하여 집수조(110)의 폐수가 상하 순환되도록 하는 펌핑분사부(520), 펌핑분사부(520)에 의해 폐수가 집수조(110)의 하층 수위에 분사시 공기(산소)가 벤츄리 구조로 분사되도록 하여 집수조(110)의 하층 수위에 공기(산소)가 공급되도록 하는 산소공급부(530) 및 베이스부(510)에 소정의 공간을 제공하고 상기 공간의 공기가 가열되도록 한 후 산소공급부(530)를 통해 집수조(110)의 하층 수위에 가열 공기가 공급되도록 하여 집수조(110)의 폐수가 대류를 통해 소정의 온도를 유지하도록 하는 공기가열부(540) 등을 포함한다. 1 to 5, the aeration apparatus 500 for a water treatment system according to the present invention includes a base part ( 510), from the base 510 to the lower water level of the water collecting tank 110, and after the wastewater of the upper or middle level of the water collecting tank 110 is pumped and sprayed on the lower level of the water collecting tank 110, the water collecting tank 110 When the wastewater is sprayed on the lower level water level of the water collecting tank 110 by the pumping spray unit 520 and the pumping spray unit 520 to circulate the waste water of the A predetermined space is provided to the oxygen supply part 530 and the base part 510 so that air (oxygen) is supplied to the lower level water level, and the air in the space is heated. and an air heating unit 540 and the like for supplying heated air to the lower water level to maintain a predetermined temperature of the wastewater of the water collecting tank 110 through convection.

여기서, 폭기장치(500)는, 베이스부(510)에 회전 가능하게 구성되고 집수조(110)의 상층 부위에 일정 부분 침수되어 집수조(110)의 상층 수위의 폐수를 퍼올려 폐수가 포말로 부서진 후 낙하되도록 하여 집수조(110)의 상층 수위에 공기(산소)가 공급되도록 하는 보조산소공급부(550)와, 보조산소공급부(550)에 장착 구성되고 보조산소공급부(550)의 회전시 집수조(110)의 상층 수위에 일정 부분 침수되어 집수조(110)의 폐수가 탈질미생물과 반응하여 탈질 처리되도록 하는 미생물디스크(560) 등을 더 포함한다.Here, the aeration device 500 is rotatably configured on the base part 510 and partially submerged in the upper layer of the water collecting tank 110 to pump up the wastewater from the upper water level of the water collecting tank 110, and after the wastewater is broken into foam The auxiliary oxygen supply unit 550 for supplying air (oxygen) to the water level in the upper layer of the water collection tank 110 by dropping it, and the auxiliary oxygen supply unit 550 is configured to be mounted and the auxiliary oxygen supply unit 550 rotates when the water collection tank 110 It further includes a microbial disk 560 and the like that is partially submerged in the upper water level of the water collecting tank 110 to react with the denitrification microorganisms to be denitrified.

한편, 폭기장치(500)는, 베이스부(510)가 집수조(110)의 상측에 설치되는 이동부(570)에 설치 구성되어 집수조(110)를 가로 및 세로 방향으로 이동하는 것이 바람직하다.On the other hand, in the aeration device 500 , it is preferable that the base part 510 is installed on the moving part 570 installed on the upper side of the water collecting tank 110 , and the water collecting tank 110 is moved in the horizontal and vertical directions.

베이스부(510)는, 집수조(110)의 상측부에 구성되고 상기 구성부들이 설치되기 위한 공간을 제공하는 수단으로서, 소정의 면적을 가지는 베이스패널(511)을 포함한다. The base unit 510 is configured on the upper side of the water collecting tank 110 and is a means for providing a space for the components to be installed, and includes a base panel 511 having a predetermined area.

펌핑분사부(520)는, 베이스패널(511)로부터 집수조(110)의 하층 수위까지 구성되고 집수조(110)의 상층이나 중층 수위의 폐수가 펌핑된 후 집수조(110)의 하층 수위에 분사되도록 하여 집수조(110)의 폐수가 상하 순환되도록 하는 수단으로서, 베이스패널(511)의 하측부에 집수조(110)의 상층이나 중층 수위에 대응되는 길이로 연장되는 폐수펌핑유입관(521), 베이스패널(511)의 하측부에 집수조(110)의 하층 수위에 대응되는 길이로 연장되는 폐수펌핑분사관(522) 및 베이스패널(511)의 상면에 위치되고 폐수펌핑유입관(521)을 통해 집수조(110)의 상층이나 중층 수위의 폐수를 펌핑한 후 폐수펌핑분사관(522)을 향해 폐수가 집수조(110)의 하층 수위에 분사되도록 하는 펌프(523) 등을 포함한다. The pumping spray unit 520 is configured from the base panel 511 to the water level in the lower layer of the water collecting tank 110, and after the wastewater of the upper or middle level of the water collecting tank 110 is pumped, sprayed to the lower level of the water collecting tank 110. As a means for allowing the wastewater of the water collecting tank 110 to circulate up and down, a wastewater pumping inlet pipe 521 extending to a length corresponding to the water level in the upper or middle layer of the water collecting tank 110 on the lower side of the base panel 511, the base panel ( 511) located on the upper surface of the wastewater pumping injection pipe 522 and the base panel 511 extending to a length corresponding to the water level in the lower layer of the water collecting tank 110 in the lower part of the water collecting tank 110, and the wastewater pumping inlet pipe 521 through the water collecting tank 110 ) after pumping the wastewater of the upper or middle layer, and a pump 523 and the like for spraying the wastewater onto the water level of the lower layer of the water collecting tank 110 toward the wastewater pumping injection pipe 522 .

여기서, 폐수펌핑유입관(521)은, 펌프(523)의 펌핑 동작시 집수조(110)의 상층 수위로부터 중층 수위의 폐수가 유입 가능하도록 하는 폐수유입구를 공지의 구조를 가질 수 있으며, 이를 통하여 집수조(110)의 수면으로부터 일정한 깊이까지의 폐수가 펌핑되도록 하여, 고압 분사되는 폐수에 의해 퇴적된 고형물이 파쇄되면서 중층이나 상층으로 부유시 다시 폐수유입구를 통해 펌핑 및 분사되는 구조가 반복되도록 하여 고형물의 파쇄를 통한 퇴적이 최대한 억제되도록 할 수 있다. Here, the wastewater pumping inlet pipe 521 may have a known structure as a wastewater inlet through which wastewater from the upper water level to the middle level water level of the water collecting tank 110 can flow in during the pumping operation of the pump 523 , and through this, the water collecting tank The wastewater from the water surface of 110 to a certain depth is pumped so that the solids deposited by the high-pressure sprayed wastewater are crushed and, when floating to the middle or upper floors, the pumping and spraying structure is repeated through the wastewater inlet so that the solids Deposition through crushing can be suppressed as much as possible.

또한, 폐수펌핑분사관(522)은 길이가 신장되거나 축소되는 구성을 가지는 것을 통하여 집수조(110)의 수위에 대응되도록 할 수 있다.In addition, the wastewater pumping injection pipe 522 may be configured to be extended or reduced in length so as to correspond to the water level of the water collecting tank 110 .

따라서 펌핑분사부(520)에 의하면, 폐수펌핑유입관(521)의 길이가 집수조(110)의 상층 수위에 대응되고 폐수펌핑분사관(522)의 길이가 집수조(110)의 하층 수위에 대응되도록 함에 따라, 상대적으로 높은 수온을 가지는 상층수가 낮은 수온을 가지는 하층 수위로 순환되도록 하여 상층 수위와 하층 수위의 수온이 일정하도록 할 수 있다. Therefore, according to the pumping injection unit 520 , the length of the wastewater pumping inlet pipe 521 corresponds to the water level in the upper layer of the water collecting tank 110 , and the length of the wastewater pumping injection pipe 522 corresponds to the water level in the lower layer of the water collecting tank 110 . Accordingly, the upper water having a relatively high water temperature is circulated to the lower water level having a lower water temperature, so that the water temperature of the upper water level and the lower water level is constant.

또한, 집수조(110)의 상층 또는 중층에 위치된 폐수가 집수조(110)의 하층에 고압으로 분사됨으로써, 무게 의해 하층에 위치된 고형물이 고압 분사되는 폐수에 의해 파쇄 및 가벼워진 상태에서 중층 또는 상층으로 부유된 후 다시 취수, 파쇄 및 분사가 반복되어 고형물의 퇴적이 최소화되며, 이에, 후처리를 위한 침전조로의 이동시 폐수 공급관 내부에 퇴적되는 것이 최소화 되어 폐수 처리 효율이 크게 향상될 수 있다.In addition, as wastewater located in the upper or middle layer of the water collecting tank 110 is injected at high pressure into the lower layer of the water collecting tank 110, the solids located in the lower layer by weight are crushed and lightened by the high-pressure sprayed wastewater to the middle or upper layer.
