이하 본 발명의 바람직한 실시 예를 첨부도면을 참조하여 보다 상세하게 설명하면 다음과 같다.Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

도1은 본 발명에 따른 오폐수 정화 처리 시스템의 구성도이다.1 is a block diagram of a wastewater purification treatment system according to the present invention.

본 발명의 오폐수 정화 처리장치도 사용하고 난 오폐수가 집수조로 유입되면 일련의 과정을 차례로 거치면서 정화 처리되어 재이용수조로 공급되게 하는 기본적인 맥락은 종래와 같다.If the wastewater used in the wastewater purification treatment apparatus of the present invention also flows into the sump, the basic context of purifying and supplying it to the reuse tank through a series of processes is the same as before.

다만, 본 발명은 더욱 효과적으로 오폐수가 정화 처리될 수 있도록 한 것으로 이는 도1에서와 같이 집수조(100), 재이용수조(110), 진공자흡식펌프(400), 부상분리조(500), 분배관(510), 배오존분해장치(520), 청소구(600)가 기본적으로 동원된다.However, the present invention is to enable the waste water to be purified more effectively, which is as shown in Figure 1, the collection tank 100, the reuse water tank 110, vacuum self-priming pump 400, floating separation tank 500, distribution pipe 510, the ozone decomposing device 520, the cleaning tool 600 is basically mobilized.

집수조(100)는 사용하고 난 오폐수가 최초 유입되는 장치이며, 재이용수조(110)는 일련의 과정을 차례로 거치면서 정화 처리된 처리수가 재이용될 수 있도록 저장되는 장치이다.The sump tank 100 is a device into which wastewater used is first introduced, and the reuse tank 110 is a device that is stored so that the treated water can be reused while going through a series of processes.

진공자흡식펌프(400)는 펌핑조(100)에 유입된 오폐수와 오존발생기(300)에서 발생된 오존화공기를 혼합시키고, 오존화공기와 혼합된 오폐수를 오존반응시켜 오폐수속의 오염물질을 산화시킬 수 있도록 공기와 혼합이 가능하도록 구성된다.The vacuum self-priming pump 400 mixes the waste water introduced into the pumping tank 100 and the ozonated air generated by the ozone generator 300 and oxidizes the pollutants in the waste water by ozone reacting the waste water mixed with the ozonated air. It is configured to be mixed with air so as to make it possible.

부상분리조(500)는 진공자흡식펌프(400)에 의해 산화된 오폐수가 내부로 유입되면 오폐수에 함유된 슬러지를 기포에 부착시켜 부상 분리되게 한 후, 분리된 슬러지는 슬러지 자동제거장치(210)에 이송시켜 제거되게 하고 처리된 처리수는 활성탄여과기(700)를 거쳐 재이용수조(110)로 공급되게 하는 역활을 수행한다.Floating separation tank 500 is attached to the sludge contained in the waste water when the oxidized waste water by the vacuum self-priming pump 400 is introduced into the air bubbles to separate the sludge, separated sludge automatic sludge removal device (210) ) To be removed by transporting the treated water and the treated water is supplied to the reuse tank 110 through the activated carbon filter 700.

상기한 부상분리조(500) 상단에는 배오존분해장치(520)가 설치되어, 부상분리조(500)에서 내부에서 반응하지 않고 남아 있는 오존을 제거하고, 부상분리조(500) 하단에는 청소구(600)가 형성되어 부상분리조(500) 내부로 투입된 슬러지가 침적되면 이를 외부로 배출시킬 수 있도록 구성된다.The ozone decomposing device 520 is installed at the top of the floating separation tank 500 to remove ozone remaining without reacting inside the floating separation tank 500, and a cleaning tool at the bottom of the floating separation tank 500. When 600 is formed and the sludge injected into the flotation tank 500 is deposited, it is configured to discharge it to the outside.

이와 같이 구성된 본 발명의 오폐수 정화 처리 시스템을 작동시키면 집수조(100)내부로 유입된 오폐수는 슬러지 자동제거장치(210)를 통하여 슬러지가 제거된 상태에서 펌핑조(200)로 투입되고, 오존발생기(300)에서는 오존화공기를 발생시킨다.When the waste water purification treatment system of the present invention configured as described above is operated, the waste water introduced into the collection tank 100 is introduced into the pumping tank 200 in a state in which sludge is removed through the automatic sludge removal device 210, and an ozone generator ( 300) generates ozonated air.

상기와 같은 상태에서 펌핑조(200)에 유입된 오폐수와, 오존발생기(300)에서 발생된 오존화공기는 진공자흡식펌프(400)에 의해 흡입되면서 혼합되고, 오존화공기와 혼합된 오폐수는 오존화공기의 오존이 빠른 속도로 오폐수 속의 오염물질과 골고루 접촉되기 때문에 오존의 직접반응과 간접반응으로 산화되며, 산화된 오폐수는 부상분리조(500)로 투입된다.The waste water introduced into the pumping tank 200 and ozone generated in the ozone generator 300 are mixed while being sucked by the vacuum self-priming pump 400 and mixed with the ozonated air. Since ozone in the ozonated air is contacted with the pollutants in the wastewater at high speed evenly, it is oxidized by direct and indirect reaction of ozone, and the oxidized wastewater is introduced into the flotation tank 500.

이때 부상분리조(500) 내부에 유입된 오폐수에는 슬러지가 다량 함유되어 있고 이러한 슬러지는 부분적으로 슬러지 침적이 발생하기 때문에 청소구(600)를 이용하여 슬러지를 빼주면 되고, 부상분리조(500) 내부에서 반응하지 않고 남아 있는 오존은 배오존분해장치(520)를 통하여 분해 제거된다. At this time, the wastewater introduced into the floating separation tank 500 contains a large amount of sludge, and since such sludge partially causes sludge deposition, the sludge may be removed using the cleaning tool 600, and the floating separation tank 500 may be used. Ozone remaining without reacting inside is decomposed and removed through the ozone decomposition apparatus 520.

한편, 부상 분리된 슬러지는 슬러지 자동제거장치(210)에 이송되어 제거되고, 용액 즉, 슬러지가 제거된 오폐수는 활성탄여과기(700)를 거쳐 재이용수조로 공급되는 것이다.On the other hand, the flotation sludge is separated and transported to the sludge automatic removal device 210 is removed, the solution, that is, waste water from which the sludge is removed is supplied to the reuse tank through the activated carbon filter (700).

이상에서 살펴본 바와 같이 본 발명에 의하면, 집수조로 유입된 오폐수를 진공자흡식펌프를 이용하여 펌핑하고, 펌핑된 오폐수는 기포에 부착시켜 부상분리 시킨 후, 오폐수에 함유된 슬러지는 슬러지 자동제거장치에 이송시켜 제거되게 하고, 슬러지가 제거된 오폐수는 활성탄 여과기를 거쳐 재이용수조로 공급되기 때문에 오폐수 속에 함유된 오염물질이 효과적으로 제거될 수 있는 등의 효과가 있는 것이다.As described above, according to the present invention, the wastewater introduced into the sump is pumped by using a vacuum self-priming pump, and the pumped wastewater is attached to bubbles to separate and float, and the sludge contained in the wastewater is automatically removed from the sludge removal apparatus. The waste water, which is transported and removed, is fed to the reuse tank through the activated carbon filter, so that contaminants contained in the waste water can be effectively removed.

이상에서는 본 발명을 특정의 바람직한 실시 예를 참고하여 설명하였으나, 본 발명은 상기한 실시 예에 한정되지 아니하며 본 발명의 요지를 벗어나지 않는 범위에서 통상의 지식을 가진 자에 의해 다양한 변경과 수정이 이루어질 수 있는 것임을 밝혀둔다.The present invention has been described above with reference to specific preferred embodiments, but the present invention is not limited to the above-described embodiments, and various changes and modifications may be made by those skilled in the art without departing from the gist of the present invention. Make sure you can.
