이상과 같이 구성되어진 본 발명의 작용 및 효과를 바람직한 실시 예에 의거하여 설명하면 다음과 같다.Referring to the operation and effect of the present invention configured as described above based on the preferred embodiment are as follows.

도 1에서 보는 바와 같이 폐수 유입관을 통해 유입되는 페수는 액 분리기(10)를 통해 액과 슬러지를 분리하여 찌꺼기는 따로 배출 시켜 소각하고 액은 페수 탱크(11)에 저장한다.As shown in FIG. 1, the wastewater introduced through the wastewater inlet pipe separates the liquid and the sludge through the liquid separator 10, incinerates wastes separately, and incinerates the liquid to be stored in the wastewater tank 11.

이어서 페수탱크(11)의 담긴 페수는 걸름 탱크(12)로 공급되고 걸름탱크(12)의 스크린(a)을 통해 미세한 입자의 찌꺼기를 분리하여 찌꺼기가 제거된 폐수는 걸름 탱크(12)에 보관된다.Subsequently, the wastewater contained in the wastewater tank 11 is supplied to the filtering tank 12, and the wastewater from which the residue is removed is separated in the filtering tank 12 by separating the fine particles from the screen (a) of the filtering tank 12. do.

걸름탱크(12)에서는 일정이상의 수위를 갖게 되면, 이는 가압 탱크(13)로 유입되고 가압 탱크(13)에서는 축산 페수를 직접가압 하며, 가압 탱크(13)를 거친 페수는 공급 라인을 따라, 가압 부상기(15)에 공급되는데, 공급 경로 상에는 페수를 희석 되게 하거나, 강제 분리시키는 반응제(NaOH)와 응집제(Alum), 그리고 응집 보조제(POLYMER)가 투입된다.When the tank 12 has a predetermined level or more, it flows into the pressurizing tank 13 and directly pressurizes livestock wastewater in the pressurizing tank 13, and the wastewater passing through the pressurizing tank 13 is pressurized along the supply line.
