본 발명은 하·폐수 정화장치에 관한 것으로 하·폐수를 처리하는 기존의 혐기조 또는 혐기성 유동층 폐수처리장치의 후단에 호기조와 침전조를 결합한 형상으로 동시에 하·폐수를 처리할 때 발생되는 냄새의 제거도 고려한 탈취장치를 반응조의 상단에 설치한 구조를 갖는 호기성 유량안정화조의 창출에 관한 것이다.The present invention relates to a sewage / wastewater purification device, which combines an aerobic tank and a sedimentation tank at the rear end of an existing anaerobic or anaerobic fluidized bed wastewater treatment system for treating sewage and wastewater. The present invention relates to the creation of an aerobic flow rate stabilization tank having a structure in which the deodorization device considered is installed at the top of the reaction tank.

기존의 혐기성유동층 폐수처리장치는 오염물질의 제거효율에 있어서 탄소, 질소, 인을 18 : 1 : 0.21의 비율로 조제한 인공합성폐수를 적용한 경우에 실험결과는 화학적산소요구량(COD)의 제거율은 55%∼77%정도이며 또한 실증적으로 제지폐수를 적용한 경우에도 화학적산소요구량의 제거율은 유입원수의 부하변동 등의 영향으로 인하여 52%∼92% 정도의 제거율을 보였다.Existing anaerobic fluidized bed wastewater treatment system uses artificial synthetic wastewater prepared with carbon, nitrogen, and phosphorus in a ratio of 18: 1: 0.21 in pollutant removal efficiency. In the case of paper wastewater, the removal rate of chemical oxygen demand was about 52% ~ 92% due to the fluctuation of load of influent.

상기한 혐기성유동층 폐수처리장치는 식품가공폐수, 주정폐수, 제지폐수, 석유화학폐수 등을 비롯한 각종 고농도 유기성 폐수의 전처리를 목적으로 최초 안출되었으나 처리공정에 있어서 유입폐수의 부하변동, 운전인자의 변동등과 같은 환경적 인자에 따라서 폐수의 처리효율이 저하되는 문제점이 있었다.The anaerobic fluidized bed wastewater treatment system was initially designed for pretreatment of various high concentration organic wastewater, including food processing wastewater, alcoholic wastewater, papermaking wastewater, petrochemical wastewater, etc. There was a problem that the treatment efficiency of the waste water is reduced according to environmental factors such as.

또한 폐수처리에 관한 환경규제 법규의 강화와 질소와 인과 같은 영양염류의 규제에도 완벽하게 대응하고 최종적으로 배출되는 배출수의 수질 향상을 위해서도 현실적으로 후속처리 장치가 요구되는 실정이다.In addition, there is a need for a post-treatment device in order to fully comply with the regulations on environmental regulations on wastewater treatment and to fully regulate the nutrients such as nitrogen and phosphorus and to improve the quality of the discharged water.

따라서 본 발명은 기존 혐기성유동층 폐수처리 장치의 문제점을 해결하기 위하여 후속처리장치로서 질소와 인과 같은 영양염류의 처리를 위한 호기성 유량안정화조를 설치할 필요가 있고 더불어 보다 효율적인 구조의 반응조가 필요하다. 즉 본 발명은 호기성유량안정화조를 설치함에 있어서 그 형상을 폐수의 폭기반응과 침전이 한 반응조에서 일어나도록 형상을 고안하고 동시에 호기성 처리에 따른 폐수의 비산과 악취의 발생을 저감시킬 수 있는 탈취장치(후드)가 설치된 구조를 창출한 것이다.Therefore, in order to solve the problems of the existing anaerobic fluidized bed wastewater treatment apparatus, it is necessary to install an aerobic flow rate stabilization tank for the treatment of nutrients such as nitrogen and phosphorus as a subsequent treatment apparatus, and a reactor having a more efficient structure is required. That is, the present invention devises a shape in which the aerobic flow rate stabilization tank is formed so that the aeration reaction and precipitation of the waste water occur in one reaction tank, and at the same time, a deodorization apparatus that can reduce the generation of effluent and odor from the aerobic treatment. (Hood) created the structure installed.

이하 발명의 요지를 첨부된 도면에 연계시켜 그 구성과 작용효과를 상세히 설명하면 다음과 같다.Hereinafter, the configuration and the effect of the present invention will be described in detail with reference to the accompanying drawings.

제1도는 종래의 일반적인 하·폐수의 탈인탈질처리의 흐름도이다.1 is a flow chart of the conventional dephosphorization treatment of general sewage and wastewater.

하·폐수를 유량조정조(1)와 스크린(2)을 통과시키고 혐기조 또는 혐기성유동층 폐수처리장치(3)와 호기성반응조(4) 그리고 침전조(5)로 처리하는 공정도이다.This is a process chart in which sewage and wastewater are passed through a flow regulating tank (1) and a screen (2) and treated with an anaerobic tank or anaerobic fluidized bed wastewater treatment apparatus (3), an aerobic reaction tank (4), and a sedimentation tank (5).

제2도는 본 발명에 따른 호기성유량안정화조의 구조도이다.2 is a structural diagram of the aerobic flow rate stabilization tank according to the present invention.

이는 기존의 제1도에서 호기성반응조(4)와 침전조(5)를 하나로 묶어 이를 호기성유량안정화조(60)라 한 것이다. 호기성유량안정화조(60)는 폭기를 위한 폭기조와 침전조를 하나로 합친 구조이다.This is referred to as aerobic flow rate stabilization tank (60) by tying the aerobic reactor (4) and the settling tank (5) as one in the existing FIG. The aerobic flow rate stabilization tank 60 is a structure in which the aeration tank and the precipitation tank for aeration are combined into one.

즉, 반응기 내부에 폭기부(61)를 두어 폭기장치를 설치하고 유체흐름에 따라서 슬러지가 침전되도록 폭기부 후단을 슬러지 침전조와 같은 형상의 인발용 호퍼(62)를 결합시킨 구조이다.That is, the aeration device 61 is installed inside the reactor to install the aeration device, and the rear end of the aeration unit combines the drawing hopper 62 having the same shape as the sludge settling tank so that sludge is settled according to the fluid flow.

이때 폭기부(61)와 인발용 호퍼(62)의 형상은 폭기와 침전에 따른 유체의 수리학적체류시간을 고려하여 설계를 한다. 인발용 호퍼(62)는 유체가 유출되는 쪽을 제2도와 같이 긴 경사면으로 한다. 그리고 호기성유량안정화조(60)의 상부는 후드(63)와 배출구(64)를 설치하고 배출구(64)에는 악취물질을 제거하기 위한 활성탄 패드(65)를 장착 및 탈착이 가능케 삽입설치하여 활성탄 교체의 편리함 부가시킨 구조로 한다.At this time, the shape of the aeration portion 61 and the drawing hopper 62 is designed in consideration of the hydraulic retention time of the fluid due to aeration and precipitation. The drawing hopper 62 makes the side from which a fluid flows out into a long inclined surface like FIG. In addition, the upper portion of the aerobic flow rate stabilization tank 60 is installed with a hood 63 and an outlet 64, and an activated carbon pad 65 is installed in the outlet 64 to remove and remove odorous substances. Convenience of added structure.

그러므로 본 발명은 호기성유량안정화조(60)를 창출하여 호기성유량안정화조의 전단부에서는 하·폐수를 폭기장치로 폭기시키고 그 후단부에서는 슬러지의 침전 및 인발을 위한 인발용 호퍼(62)를 구성하여 하·폐수를 처리하는 공정 및 형상을 창출한 것이다.Therefore, the present invention creates an aerobic flow rate stabilization tank 60 to aeration at the front end of the aerobic flow rate stabilization tank by aeration device and to form a drawing hopper 62 for sedimentation and drawing of sludge at the rear end thereof. It created a process and shape for treating sewage and wastewater.
