Description
본 고안은 수질오염방지시설에서 사용되는 침전지 계면관리에 관한 것이다.The present invention relates to the sedimentation basin management used in water pollution prevention facilities.
일반적으로 침전지의 슬러지 인발은 타이머에 의해 설정된 시간동안 슬러지 계면과는 무관하게 펌프에 의해 인발되거나 인력에 의해 계면측정기로 측정 후 펌프를 가동하여 슬러지 계면을 관리해 왔다. 이로 인해 슬러지 이외의 상등수가 함께 배출되거나 인력에 의해 측정해야 함으로 인력의 소요가 많은 문제점이 발생하였다. 최근 시도되고 있는 방식은 침전지 안에 초음파식 또는 광학식 등의 센서를 설치하여 침전지 안의 슬러지 농도나 계면을 측정하여 펌프와 연결하는 방식이 시도되고 있으나 침전지 안에 설치된 센서류에 부유물이 쉽게 부착되어 정도가 떨어지고 오동작하는 문제점이 발생하였다. 경우에 따라서 센서 자동세척장치를 부착하는 경우도 있으나 센서 자체가 부유물이 많은 침전지 내의 물에 담겨있어 충분한 세척효과를 기해할 수 없는 문제점이 있다.In general, the sludge withdrawal of the sedimentation basin has been managed by the pump after being drawn by the pump or measured by the interface meter by manpower regardless of the sludge interface for the time set by the timer. This caused a lot of manpower requirements because the supernatant other than sludge should be discharged together or measured by manpower. Recently attempted method is to install a sensor such as ultrasonic or optical in the sedimentation basin to measure the sludge concentration or interface in the sedimentation basin and to connect it to the pump, but the suspended matter is easily attached to the sensors installed in the sedimentation basin A problem occurred. In some cases, the automatic sensor cleaning device is attached, but there is a problem that the sensor itself is contained in the water in the sedimentation basin with a lot of suspended solids, which can not impair the sufficient cleaning effect.
본 고안은 상기와 같은 문제점을 해소하기 위해 센서부의 오염이 없고 센서의 상태를 육안으로도 쉽게 관측이 가능하도록 측정부를 외부에 별도로 설치하고 측정대상 시료를 펌프 등에 의해 측정부로 이송되도록 이루어진 것에 특징이 있다.In order to solve the above problems, the present invention is characterized in that the measurement unit is separately installed so that there is no contamination of the sensor unit and the state of the sensor can be easily observed with the naked eye, and the sample to be measured is transferred to the measuring unit by a pump or the like. have.

이하 첨부된 도면에 의해 상세히 설명하면 다음과 같다.Hereinafter, described in detail by the accompanying drawings as follows.
도 1은 침전지(T) 내의 하부에 침전된 슬러지(S)를 인발하여 측정후 지시치에 의하여 펌프(P)가 가동되도록 하는 구조도로서 침전지(T)에 침전된 슬러지(S) 양이 증가하여 상한설정높이(H) 이상이 되었을 때 외부에 설치된 농도측정부(M)에서는 시료의 농도를 간헐적으로 또는 지속적으로 검출하여 슬러지(S) 계면이 상한 설정높이(H)에 도달되었음을 판단하게 되고 이 결과치에 의해 펌프(P)에 기동신호를 보내게 된다. 펌프가 가동되어 슬러지 계면이 하한설정높이(L)에 도달하게 되면 마찬가지로 농도측정부(M)에서 슬러지(S)의 농도를 통해 하한설정높이(L)에 도달하였음을 판단하게 되고 펌프(P)에 정지신호를 보내어 펌프(P)가 정지하게 되어 슬러지(S) 계면이 상한설정높이(H)와 하한설정높이(L) 사이에서 유지될 수 있다. 또한 농도검출 후에는 세척라인(C)을 통해 유입된 청수에 의해 농도측정부(M)의 센서부가 세척됨으로써 농도측정부(M)는 청결한 상태가 유지되어 정도의 감소나 오동작을 방지할 수 있다.1 is a structural diagram that draws sludge (S) precipitated in the lower part in the sedimentation basin (T) to operate the pump (P) according to the measured value after measurement, the amount of sludge (S) deposited in the sedimentation basin (T) increases and the upper limit When the height exceeds the set height (H), the concentration measuring unit (M) installed on the outside detects the concentration of the sample intermittently or continuously to determine that the sludge (S) interface has reached the upper limit set height (H). The start signal is sent to the pump P. When the pump is operated and the sludge interface reaches the lower limit set height (L), the concentration measuring unit (M) determines that the lower limit set height (L) has been reached through the concentration of the sludge (S). The pump (P) is stopped by sending a stop signal to the sludge (S) interface can be maintained between the upper limit set height (H) and the lower limit set height (L). In addition, after detecting the concentration, the sensor unit of the concentration measuring unit M is washed by fresh water introduced through the washing line C, so that the concentration measuring unit M is kept clean, thereby preventing a decrease or malfunction of the degree. .
이상에서 상술한 바와 같이 본 고안은, 농도측정용 센서 등의 농도측정부를 수중이 아닌 외부에 설치함으로써 센서의 오염을 방지하고 유지관리를 쉽도록 하여 정도가 높은 슬러지 농도측정이 가능하고 슬러지 계면을 정확히 관리할 수 있는 것이다.As described above, the present invention, by installing a concentration measuring unit such as a concentration measuring sensor to the outside, not in the water to prevent contamination of the sensor and easy maintenance, it is possible to measure the sludge concentration of high accuracy and to make the sludge interface It can be managed accurately.
