이와 같이 구성된 종래 하수처리장의 하수처리공정을 개략적으로 설명하기로 한다.The sewage treatment process of the conventional sewage treatment plant constructed as described above will be schematically described.

도 1에서와 같이 각 가정 등에서 발생 되는 하수가 유입펌프장(100)으로 유입되어 유량저장조(200)로 공급 저장된 다음, 유량조정조(200)로부터 반응조(300) 의 유입공정(310)으로 유입되고, 산소공급, 유기물산화, 분해, 인의 과잉 섭취 및 제거를 하기 위한 포기공정(320), 교반, 포기중지, 슬러지와 처리수를 분리하는 침전공정(330) 및 처리수 및 슬러지를 배출하기 위한 배출공정(340)이 순차적으로 진행되어 슬러지는 슬러지 저류조(380)로 별도로 배출되고, 처리수는 디켄터펌프(350)를 통하여 처리수조(400)로 공급된 다음, 생물막조(500)로 공급되어 필터링 및 미생물로써 분해되고, 소독설비(600)로 공급되어 소독처리되며, 유량계(700)로 공급되어 양을 계측하여 배출 처리된다.As shown in FIG. 1, the sewage generated in each of the households is introduced into the inflow pump station 100, is supplied to the flow storage tank 200, then flows into the inflow process 310 of the reaction tank 300 from the flow control tank 200, (330) for separating sludge and treated water, and a discharging process (330) for discharging treated water and sludge, and a discharging process for discharging treated water and sludge And the sludge is discharged separately to the sludge storage tank 380. The treated water is supplied to the treatment water tank 400 through the decanter pump 350 and then supplied to the biofilm tank 500 to be subjected to filtration and / Is disassembled as a microorganism, is supplied to a disinfection facility (600), is disinfected, is supplied to a flow meter (700), and is discharged and processed.

한편, 도 2에서와 같이 반응조(300)의 배출공정(340)에 대한 동작상태를 개략적으로 설명하기로 한다. 2, the operation of the reaction tank 300 in the discharging process 340 will be schematically described.

먼저, 유량저장조(200)로부터 공급되는 하수가 반응조(10)의 유입공정(310)으로 유입되고, 반응조(10) 외부에 설치된 송풍기(미도시)로부터 반응조(10) 내부로 공기가 공급되어 포기공정(320)이 진행되고, 송풍기가 작동을 멈추면 침전공정(330)이 진행되어 처리수(301)와 슬러지(302)가 분리되며, 슬러지(302)는 반응조(300) 내부의 슬러지/처리수 계면(303)까지 침전된다.First, the sewage supplied from the flow rate storage tank 200 flows into the inflow step 310 of the reaction tank 10, air is supplied into the reaction tank 10 from a blower (not shown) provided outside the reaction tank 10, When the process 320 is performed and the blower stops operating, the settling process 330 proceeds to separate the treated water 301 and the sludge 302, and the sludge 302 is sludge / treated in the reaction tank 300 Water interface 303 as shown in Fig.

이때, 조류판(360)의 상부 영역에 침적되는 슬러지(302)를 제거하기 위하여 에어리프트펌프(372)가 동작되면서 송기관(37)을 통해 에어리프트관(366)의 일측으로 공기가 공급되면, 에어리프트관(366) 내에서 기포로 부상하게 된다.When the air lift pump 372 is operated to remove the sludge 302 deposited on the upper portion of the bird's plate 360 and air is supplied to one side of the air lift tube 366 through the air supply pipe 37 , And the air lift tube (366) is floated in air bubbles.

이와 같이 기포가 상승함과 동시에 에어리프트관(366) 내에는 부압이 형성되고, 부압이 형성됨에 따라 조류판(360)의 상부 영역에 침적된 슬러지(302)가 수직관(362) 내로 빨려 들어가게 되고, 수직관(362)을 통해 빨려들어간 슬러지(302)는 연결관(364)과 에어리프트관(366)을 거쳐 반응조(300) 외부의 슬러지 저류조(380)로 배출된다.As the air bubbles rise, a negative pressure is formed in the air lift tube 366. As the negative pressure is formed, the sludge 302 deposited in the upper region of the bird plate 360 is sucked into the vertical tube 362 The sludge 302 sucked through the vertical pipe 362 is discharged to the sludge storage tank 380 outside the reaction tank 300 via the connection pipe 364 and the air lift pipe 366.

결국, 침전공정(330)중 침적된 슬러지(302)는 슬러지 처류조(380)로 이송되어 조류판(360)의 상부에 존재하지 않게 되고, 조류판(360) 상부에 수직브라켓(354)로써 구비된 디켄터펌프(350)가 동작되어, 조류판(360) 상부 영역의 처리수(301)가 디켄터펌프(350) 일측의 토출구(352)에 구비된 처리수배출관(356)을 통하여 처리수조(400)로 공급 처리된다.As a result, the deposited sludge 302 in the sedimentation step 330 is transferred to the sludge holding tank 380 and is not present in the upper part of the bird plate 360, and as a vertical bracket 354 on the bird plate 360 The treated decanter pump 350 is operated so that the treated water 301 in the upper region of the bird's plate 360 flows through the treated water discharge pipe 356 provided in the discharge port 352 of the decanter pump 350, 400).

그러나, 반응조의 배출공정에서 디켄터펌프의 동작으로 처리수가 토출구 상부에 구비된 처리수배출관을 통해 처리수조로 배출시, 디켄트펌프 내부에 포기공정후 잔류하고 있는 에어로 인해 펌프의 토출불량이 발생되어 수처리가 어려워져 반응조의 정상적인 사이클 운전을 할 수 없어, 운영상 어려움이 발생되었다.However, when the process water is discharged to the treated water tank through the treated water discharge pipe provided at the upper portion of the discharge port by the operation of the decanter pump in the discharge process of the reaction tank, the discharge failure of the pump occurs due to the air remaining after the aeration process inside the decanter pump Water treatment became difficult and normal cycle operation of the reaction tank could not be carried out, resulting in operational difficulties.

본 고안은 이와 같은 종래의 문제점을 해결하기 위하여 안출된 것으로, 본 고안의 목적은 반응조의 배출공정에서 디켄터펌프의 동작으로 처리수가 토출구 상부에 구비된 처리수배출관을 통해 처리수조로 배출시, 포기공정후 잔류하고 있는 에어가 처리수와 함께 디켄터펌프 내부로 유입되면 에어를 외부, 즉 반응조로 신속하게 배출시킬 수 있도록 구성한 수중 펌프내 토출부 개선장치를 제공하는 데 있다.It is an object of the present invention to provide an apparatus and a method for disposing a disinfection pump in a disposing process of a reactor, And the air can be quickly discharged to the outside, that is, the reaction tank, when the air remaining after the process flows into the decanter pump together with the treated water.

도 4 및 도 5에서와 같이, 각 가정 등에서 발생되는 하수가 유입펌프장(10)으로 유입되어 유량저장조(20)로 공급 저장된 다음, 유량조정조(20)로부터 반응조(10)의 유입공정(32)으로 유입되어, 산소공급, 유기물산화, 분해, 인의 과잉 섭취 및 제거를 하기 위한 포기공정(34), 교반, 포기중지, 슬러지와 처리수를 분리하는 침전공정(36) 및 처리수 및 슬러지를 배출하기 위한 배출공정(38)이 순차적으로 진행되어 슬러지는 슬러지 저류조(39)로 별도로 배출되고, 처리수는 디켄터펌프(80)를 통하여 처리수조(40)로 공급된 다음, 생물막조(50)로 공급되어 필터링 및 미생물로써 분해되고, 소독설비(60)로 공급되어 소독처리되며, 유량계(70)로 공급되어 양을 계측하여 배출 처리된다.4 and 5, the wastewater generated in each household is introduced into the inflow pump station 10 and is supplied to the flow rate storage tank 20 and then supplied from the flow rate adjustment tank 20 to the inflow stage 32 of the reaction tank 10, (34) for performing oxygen supply, organic oxidation, decomposition, excessive intake and removal of phosphorus, a stirring step, a stopping step, a precipitation step (36) for separating sludge and treated water, and a step for discharging treated water and sludge And the sludge is discharged separately to the sludge storage tank 39. The treated water is supplied to the treatment water tank 40 through the decanter pump 80 and then supplied to the biofilm tank 50 And is supplied to the disinfection facility 60 for disinfection treatment and is supplied to the flow meter 70 for measuring the amount thereof and discharged.

한편, 도 6에서와 같이 반응조(30)의 배출공정(38)에 대한 동작상태를 개략적으로 설명하기로 한다. 6, the operation of the reaction tank 30 in the discharging process 38 will be schematically described.

먼저, 하수가 유량저장조(20)로부터 반응조(10)의 유입공정(32)으로 유입되고, 반응조(10) 외부에 설치된 송풍기(미도시)로부터 반응조(10) 내부로 공기가 공급되어 포기공정(34)이 진행되며, 송풍기가 작동을 멈추면 침전공정(36)이 진행되어 처리수(1)와 슬러지(2)가 분리되고, 슬러지(2)는 반응조(30) 내부의 슬러지/처리수 계면(3)까지 침전된다.First, the sewage flows into the inflow step 32 of the reaction tank 10 from the flow rate storage tank 20, air is supplied into the reaction tank 10 from a blower (not shown) provided outside the reaction tank 10, And the sludge 2 is separated from the sludge / treatment water interface 34 in the reaction tank 30 by the sedimentation process 36, (3).

이때, 조류판(84)의 상부 영역에 침적되는 슬러지(2)를 제거하기 위하여 에어리프트펌프(89)가 동작되면서 송기관(37)을 통해 에어리프트관(87)의 일측으로 공기가 공급되면, 에어리프트관(87) 내에서 기포로 부상하게 된다.At this time, when air is supplied to one side of the air lift tube 87 through the air supply pipe 37 while the air lift pump 89 is operated to remove the sludge 2 deposited on the upper region of the bird plate 84 , And the air lift tube (87) is floated in air bubbles.

이와 같이 기포가 상승함과 동시에 에어리프트관(87) 내에는 부압이 형성되고, 부압이 형성됨에 따라 조류판(84)의 상부 영역에 침적된 슬러지(2)가 수직관(85) 내로 빨려들어가게 되고, 수직관(85)을 통해 빨려들어간 슬러지(2)는 연결관(86)과 에어리프트관(87)을 거쳐 반응조(30) 외부의 슬러지 저류조(39)로 배출된다.As the air bubbles rise, a negative pressure is formed in the air lift tube 87. As the negative pressure is formed, the sludge 2 deposited in the upper region of the bird plate 84 is sucked into the vertical tube 85 The sludge 2 sucked through the vertical pipe 85 is discharged to the sludge storage tank 39 outside the reaction tank 30 via the connection pipe 86 and the air lift pipe 87.

결국, 침전공정(36)중 침적된 슬러지(2)는 슬러지 처류조(39)로 이송되어 조류판(84)의 상부에 존재하지 않게 되고, 조류판(84) 상부에 스직브라켓(82)로써 구비된 디켄터펌프(80)가 동작되어, 조류판(84) 상부 영역의 처리수(1)가 디켄터펌프(80) 일측의 토출구(81)에 구비된 처리수배출관(83)을 통하여 처리수조(40)로 공급 처리된다.As a result, the deposited sludge 2 in the sedimentation step 36 is conveyed to the sludge holding tank 39 so that it does not exist in the upper part of the algae plate 84, and as the swirl bracket 82 on the algae plate 84 The treated decanter pump 80 is operated so that the treated water 1 in the upper region of the bird plate 84 flows through the treated water discharge pipe 83 provided in the discharge port 81 on one side of the decanter pump 80 40).

한편, 도 7 및 도 8에서와 같이 반응조(30)의 배출공정(38)에서 디켄터펌프(80)의 동작으로 처리수(1)가 토출구(82) 상부에 구비된 처리수배출관(83)을 통해 처리수조(40)로 배출시, 포기공정(34)후 잔류하고 있는 에어가 처리수(1)와 함께 디켄터펌프(80) 내부로 유입된다.7 and 8, in the discharging process 38 of the reaction tank 30, the treated water 1 is supplied to the treated water discharge pipe 83 provided above the discharge port 82 by the operation of the decanter pump 80 The air remaining after the aeration process 34 flows into the decanter pump 80 together with the treatment water 1. [

그러면, 도 8에서와 같이 디켄터펌프(80)의 케이스(80a)에 형성된 결합 나사공(90)에 외주면의 수나사(92a)로써 체결된 조인트볼트(92)의 에어 및 처리수 유입공(92b)을 통해 처리수(1)와 함께 에어가 유입되면, 조인트볼트(92)의 수나사(92a)에 암나사(92a)로써 체결된 에어배출챔버(94) 내주면에 삽입된 부상차단볼(96)이, 처리수(1)의 수압에 의해 상방으로 서서히 부상하게 되고, 이와 동시에 에어배출챔버(94) 내주면과 부상차단볼(96) 외주면 사이를 통하여 에어가 에어배출챔버(94) 상단의 에어배출공(94b)을 통해 외부, 즉 반응조(30) 내부로 신속하게 배출되고, 처리수에 의해 계속적으로 상승하는 부상차단볼(96)에 의해 에어배출공(94b)이 차단되어 처리수(1)는 더이상 배출되지 않게 된다.8, the air of the joint bolt 92 fastened to the case 80a of the decanter pump 80 by the male screw 92a of the outer circumferential surface and the air of the process water inflow hole 92b of the joint bolt 92, The injured block ball 96 inserted into the inner circumferential surface of the air discharge chamber 94 fastened with the female screw 92a to the male thread 92a of the joint bolt 92 is inserted into the joint bolt 92, At the same time, the air flows between the inner circumferential surface of the air discharge chamber 94 and the outer circumferential surface of the floatation blocking ball 96 by the water pressure of the treatment water 1, The air discharge hole 94b is shut off by the floatation blocking ball 96 which is rapidly discharged to the outside, that is, the inside of the reaction tank 30 via the water discharge holes 94b, 94b, It is not discharged.

이에 따라 처리수(1)와 함께 유입되는 에어에 의해 디켄터펌프(80)의 효율이 떨어지지 않고 동작되어 처리수(1)를 원활하게 처리할 수 있게 된다.Accordingly, the effluent of the decanter pump 80 can be operated without the efficiency of the decanter pump 80 being lowered by the air introduced together with the treated water 1, so that the treated water 1 can be smoothly treated.

이후, 에어배출챔버(94) 내부의 차단수(1)가 조인트볼트(92)의 에어 및 처리수 유입공(92b)을 통해 토출구(82) 상부의 처리수배출관(83)을 통해 처리수조(40)로 배출되면, 부상차단볼(96)이 하강하여 조인트볼트(92)의 에어 및 처리수 유입공(92b) 상단 내주면을 차단하게 된다.The interception water 1 in the air discharge chamber 94 is discharged through the air of the joint bolt 92 and the process water inflow hole 92b through the process water discharge pipe 83 above the discharge port 82 40, the floatation blocking ball 96 is lowered to block the air of the joint bolt 92 and the inner peripheral surface of the upper end of the process water inflow hole 92b.
