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. It is supplied to the flotation unit 15, and the reactant (NaOH), flocculant (Alum), and flocculation aid (POLYMER) for diluting or forcibly separating wastewater are introduced on the feed path.
즉, 약품 공급부(14)에는 각각의 약품을 충진시키고, 가동되게 하면 교반동작이 이루어 지고, 약품 공급부(14)에 저장된 약품은 순환펌프의 펌핑에 의해 가압 탱크(13)에 공급되고, 일정압으로 교반되어, 상기 폐수 공급 경로를 따라 공급되면서, 폐수와 섞이게 되어 반응이 일어나게 되는데, 이러한 약품은 가압 탱크(13)에서 물과 혼합 및 반응되게 한다.That is, the medicine supply unit 14 is filled with the respective chemicals, the operation is performed when the operation is made, the chemicals stored in the chemical supply unit 14 is supplied to the pressure tank 13 by the pumping of the circulation pump, a constant pressure As it is stirred, and supplied along the wastewater supply path, it is mixed with the wastewater, the reaction occurs, this chemical is allowed to mix and react with water in the pressure tank (13).
이어서 일정압으로 압축된 폐수는 가압 부상기(15)에 공급 될 때에 고압의 페수는 자연압으로 바뀌면서 공급되고, 약품에 의해 슬러지 등과 결합되어 유입구의 유체적 공급 라인 믹서에 주입 되어 가압 부상기(15) 내에서 응집이 이루어진다.Subsequently, when the wastewater compressed to a constant pressure is supplied to the pressure flotation unit 15, the high pressure wastewater is supplied while being converted to natural pressure, and is combined with sludge by a chemical and injected into the fluid supply line mixer at the inlet to pressurized flotation ( 15) Agglomeration takes place.
이때, 응집된 슬러지 등은 가압 부상기(15)의 수면 위에 떠오르게 되는데, 실험에 의하면, 가압 부상기(14) 내의 부유물 부상속도는 1m-2m/분이 소요되며, 축산 폐수 처리 시간은 1∼5분 정도가 소요되었다.At this time, the flocculated sludge or the like floats on the water surface of the pressure flotation device 15. According to the experiment, the floating flotation speed in the pressure flotation device 14 takes 1m-2m / min, and the livestock wastewater treatment time is 1-5. It took about a minute.
한편, 가압 부상기의(15) 상측부에 마련된 플로터에 의해, 슬러지가 제거되고 이는 슬러지 공급경로를 따라 슬러지 저장조(17)에 저장되는 것이다.On the other hand, the sludge is removed by the floater provided in the upper portion of the pressure floating body 15, which is stored in the sludge storage tank 17 along the sludge supply path.
또한, 가압 부상기(15)에서 계속적으로 유입되는 페수에서 슬러지를 제거하고, 남은 폐수는 1차 처리수 탱크(16)에 공급되면서, 일정시간 경과후에 펌핑으로 카본 필터(c), 샌드필터(s), 마이크로 필터(m)를 순차적으로 거치면서, 불순물을 완전 제거하고, 용액 여과기(19)를 강제로 통과시켜 최종적인 정수처리를 수행하게 된다.In addition, the sludge is removed from the wastewater continuously introduced from the pressurized floater 15, and the remaining waste water is supplied to the primary treated water tank 16, and after a predetermined time, the carbon filter (c) and the sand filter (pumping) are pumped. s), while sequentially passing through the micro filter (m), the impurities are completely removed, and the solution filter 19 is forced through the final water treatment.
이어서, 모든 과정을 거친 정수는 2차 처리수 탱크에 유입되고, 이는 다시 자외선 살균기(21)와 마이크로 필터(22)를 거쳐 최종적으로 역삼투압막(23)을 거쳐 찌꺼기는 걸름탱크(12)로 순환되고 나머지 정화수는 용도에 따라 방류되는 것이다.Subsequently, all the purified water flows into the secondary treated water tank, which is again passed through the UV sterilizer 21 and the micro filter 22 and finally through the reverse osmosis membrane 23 to the filtering tank 12. The remaining purified water is circulated and discharged depending on the application.
이상에서 설명된 바와 같이 본 발명은, 축산 폐수 처리 효과가 기존의 방식에 비해 뛰어나며, 유지비가 저렴하고, 별도의 응집, 반응조가 불필요하며, 면적이 작아 어느 곳에나 설치 할 수 있으며, 기존의 축산 페수를 처리함에 있어서, 보다 효과적으로 처리할 수 있게된 발명인 것이다.As described above, the present invention, the livestock wastewater treatment effect is superior to the existing method, the maintenance cost is low, no separate aggregation, the reaction tank is required, the area is small, can be installed anywhere, the existing livestock In the treatment of waste water, it is an invention that can be treated more effectively.
