Description

침전조와 유수분리기를 포함하는 폐수 처리장치{wastewater treatment apparatus including sedimentation tank and water separator}Wastewater treatment apparatus including sedimentation tank and water separator}

본 발명은 침전조와 유수분리기를 포함하는 폐수 처리장치에 관한 것으로서, 더욱 상세히는 처리조 내에서 이동되는 수류의 흐름을 공간 흐름 형태로 바꿔주되 유속을 최대한 느리게 하고, 배출조로의 배출 방향을 상하 여러 곳에 분산시켜서 수류의 상하 공간 분산 및 수위 조절로 침전 및 유수 분리 효율을 극대화할 수 있는 침전조와 유수분리기를 포함하는 폐수 처리장치에 관한 것이다.The present invention relates to a wastewater treatment apparatus including a sedimentation tank and an oil / water separator. More specifically, the flow of water flowing in the treatment tank is changed to a spatial flow form, but the flow rate is as slow as possible, The present invention relates to a wastewater treatment apparatus including a sedimentation tank and an oil / water separator capable of maximizing sedimentation and oil / water separation efficiency by dispersing the space up and down and adjusting the water level.

일반적으로 폐수는 각 가정 및 공공건물, 영업건물 등에서 배출되는 오,폐수와 공장에서 배출되는 공장폐수로 구별되며, 공장폐수는 다시 넓은 뜻의 산업폐수에 포함되고, 이러한 각종 폐수(이하 오,폐수를 통칭함)는 오염물질을 처리하지 않고 그대로 방류할 경우 수질오염과 토양오염 등의 원인이 되고 있다.In general, wastewater is classified into wastewater discharged from each home, public building, and business building, and factory wastewater discharged from a factory. Factory wastewater is again included in industrial wastewater in a broad sense, and various waste water (hereinafter, wastewater) Collectively) is the cause of water pollution and soil pollution when discharged as it is without treatment.

그러므로 상기 폐수는 대부분 부상조, 침전조, 유수분리기를 이용한 폐수 처리장치를 이용하여 오염물질을 처리하고 있다.Therefore, most of the wastewater is treated with contaminants using a wastewater treatment apparatus using a flotation tank, a sedimentation tank, and an oil / water separator.

상기 침전조는 폐수 중에서 물보다 무거운 물질을 처리조의 하부로 침전시켜 제거하는 고/액 분리장치이다.The settling tank is a solid / liquid separation device that removes the material heavier than water in the wastewater by sedimenting the lower part of the treatment tank.

상기 유수분리기는 폐수 중 기름처럼 물보다 가벼운 물질(자연스럽게 부상)의 자체 부상력을 이용하여 물과 분리시키는 장치이다.The oil / water separator is a device that separates water from water by using a self-levitation force of a material (naturally floating) that is lighter than water in the wastewater.

상기 부상조를 이용한 수처리장치는 폐수인입구를 통해 내부로 유입된 폐수를 수평으로 흐르게 하면서 물보다 가벼운 이물질을 처리조 상부로 부상시켜 제거하는 고/액 분리 방식의 장치이다.The water treatment apparatus using the flotation tank is a solid / liquid separation device that floats the wastewater introduced into the interior through the wastewater inlet horizontally and floats and removes the foreign matter lighter than the water to the upper portion of the treatment tank.

상기 부상조를 이용한 수처리장치는 폐수 속에 포함된 슬러지의 부상 효율성이 떨어짐에 따라 부상슬러지 수집기로 수집되는 수거량이 미미하여 폐수처리 기능이 떨어지며, 침전조 및 유수분리기를 이용한 폐수 처리장치는 수평의 수류 흐름만으로 침전시키는 방식이어서 처리 효율이 높지 못하다고 할 수 있다.The water treatment apparatus using the flotation tank has a small amount of waste collected by the flotation sludge collector as the efficiency of sludge contained in the waste water decreases, so that the wastewater treatment function is reduced. The wastewater treatment apparatus using the sedimentation tank and the oil / water separator has only a horizontal flow of water. Because of the method of precipitation, it can be said that the treatment efficiency is not high.

폐수 처리장치의 선행기술로는 아래 특허문헌에 개시된 바와 같이 본원 출원인이 개발하여 제10-0789996호로 등록받은 대한민국 공개특허공보 공개번호 제10-2007-0048142호(2007.05.08.공개)의 "부상조와 침전조와 유수분리기를 포함하는 폐수처리장치"가 있다.(이하 '선행기술 1'이라 칭함)As the prior art of the wastewater treatment apparatus, as disclosed in the patent document below, "Injury" of Korean Patent Application Publication No. 10-2007-0048142 (published on May 8, 2007), which was developed by the present applicant and registered as No. 10-0789996, is disclosed. Wastewater treatment system comprising a tank, a sedimentation tank and an oil / water separator ”(hereinafter referred to as“ prior art 1 ”).

상기 선행기술 1은 폐수처리조 내부에 구멍이 다수 형성된 수류분산패널을 1개 이상 다수 구비하고, 수류분산패널 뒤쪽에는 다수의 경사판이 일정간격으로 채워진 침전유도통을 설치하며, 폐수인입구와 대향된 반대쪽에는 상하로 조절되는 이동부재와 고정부재에 의해 간격이 조절되는 유입구를 구비하고, 수류분산패널 사이에 경사판이 비스듬히 설치된 침전유도통을 구비하며, 유입구의 크기 조절에 따라 폐수배출구로 배출되는 수량을 조절함으로써 폐수의 수류압 및 속도를 조절하여 슬러지의 부상 및 침전 효과를 높이도록 한 것이다.The prior art 1 is provided with at least one water dispersion panel having a plurality of holes formed in the wastewater treatment tank, the rear side of the water dispersion panel is installed with a set of sedimentation induction through which a plurality of inclined plates are filled at a predetermined interval, facing the wastewater inlet On the opposite side is provided with an inlet which is controlled by a moving member and a fixed member which are adjusted up and down, and has a settling induction pipe installed at an oblique angle between the water distribution panel, and discharged to the wastewater outlet according to the size of the inlet. By adjusting the water pressure and speed of the waste water to increase the flotation and sedimentation effect of the sludge.

상기 선행기술 1은 경사판이 비스듬히 경사져 설치된 침전유도통을 사용하는 것으로서, 수류의 흐름을 하향으로 유도하여 오,폐수의 침전물을 아래쪽으로 유도하는 효과는 좋지만 수류의 흐름이 수평으로 같은 위치에서만 일률적으로 행하여져서 이물질의 부상효과를 높이지 못하였다.The prior art 1 uses a sedimentation induction pipe installed at an oblique angle to the inclined plate, and the effect of inducing sediment of wastewater and wastewater by inducing the flow of water downward is good but the flow of water is uniformly only at the same position horizontally. It did not increase the floating effect of the foreign matter.

또 다른 폐수 처리장치로는 '대한민국 공개특허공보 제10-2012-0068327호(2012년6월27일 공개)의 '폐수처리장치의 수류 공간흐름을 이용한 수직유도판형 가압부상조"가 있다.(이하 '선행기술 2'라 칭함)Another wastewater treatment device is a vertical induction plate pressurization tank using the water flow space of the wastewater treatment device of Korea Patent Publication No. 10-2012-0068327 (published June 27, 2012).

상기 선행기술 2는, 폐수인입구와 폐수배출구 사이에 수류분산패널을 설치하여 폐수처리장치를 구성할 때 단면이 웨이브 형태인 수십개의 수직유도판이 세워진 수직공간흐름유도부를 수류분산패널 사이에 설치하고, 폐수처리조 후미에 격리된 수류조절조 바닥에는 수류가 상향 유입되는 수류조절배관을 설치하고, 수류조절조 전방에는 수류를 수류조절배관 아래쪽으로 유도하는 격벽을 설치하여 수류분산패널과 수직유도판들이 수류의 흐름을 상하의 공간흐름으로 바꿔주면서 수류의 유속을 느리게 하여 이물질의 부상시간을 충분히 확보하여 주도록 함으로써 이물질 부상 효율을 높일 수 있도록 한 것이다.In the prior art 2, when installing the wastewater treatment device by installing the water distribution panel between the wastewater inlet and the wastewater outlet, the vertical space flow induction section in which dozens of vertical guide plates having a wave cross section is installed between the water dispersion panel, At the bottom of the water flow control tank, which is isolated at the rear of the waste water treatment tank, a water flow control pipe is installed at the bottom of the water flow control, and a partition wall that guides the water flow down the water flow control pipe is installed at the front of the water flow control tank. By changing the flow of the flow up and down the space flow while slowing the flow of the water flow to ensure a sufficient time for the injuries of foreign objects by increasing the efficiency of foreign matters.

그러나 상기 선행기술 2는 수류조절배관이 수류조절조의 바닥에 일정 높이로 고정되어 있는 것이므로 수류조절조의 수위 조절이 어려워서 수류량에 따른 유속 조절을 좀 더 미세하게 조절하지 못함에 따라 폐수의 처리 효율을 극대화시키지 못하는 문제점이 있다.However, the prior art 2 is because the water flow control pipe is fixed to the bottom of the water flow control tank at a certain height, it is difficult to control the water level of the water flow control tank to adjust the flow rate according to the flow rate more finely, thereby improving the treatment efficiency of the wastewater. There is a problem that cannot be maximized.
