본 고안은 유기성 폐수를 정화하는 과정에 있어서 폐수속 용존산소(dissolved oxygen)를 측정하기 위한 측정캡에 관한 것이다.The present invention relates to a measuring cap for measuring dissolved oxygen in wastewater in the process of purifying organic wastewater.
제4도는 폐수가 저장된 원수탱크(11)에서 반응기(14)로 일정량의 폐수가 공급되고 산소탱크(12)에서는 미생물의 활성화를 위해 반응기(14)로 산소가 공급되어 미생물에 의해 폐수처리가 이루어지는 개략적인 구조를 보인 것이다.4 is a predetermined amount of wastewater is supplied to the reactor 14 from the raw water tank 11 in which the wastewater is stored, and oxygen is supplied to the reactor 14 to activate the microorganisms in the oxygen tank 12 to treat wastewater by the microorganisms. It is a schematic structure.
미생물은 이용한 폐수처리, 구체적으로 유기성폐수를 정화함에 있어서는 반응기(14)에 산소를 공급하여 반응기(14) 내부에 있는 매생물을 활성화시켜 유기성폐수를 정화하는 방법이 널리 이용되고 있으며, 이를 활성오니 법이라 칭하고 있다.In the treatment of wastewater using microorganisms, specifically, in purifying organic wastewater, a method of purifying organic wastewater by activating a medium inside the reactor 14 by supplying oxygen to the reactor 14 is widely used. It is called the law.
상기한 활성오니법은 대기중의 산소를 유기성폐수를 충분히 공급하면 호기성(好氣性)세균이 번식하여 산화작용을 촉진하는 원리를 이용한 것으로 특히, 산소함량이 90%이상인 고순도의 산소를 사용하여 염색폐수와 같은 악성폐수를 정화하는 것을 산소활성오니법이라 한다.The activated sludge method uses a principle that promotes oxidation by breeding aerobic bacteria when oxygen in the air is sufficiently supplied with organic wastewater, and in particular, dyeing using high purity oxygen having an oxygen content of 90% or more Purifying malignant wastewater, such as wastewater, is called oxygen-activated sludge method.
상기한 활성오니법 또는 산소활성오니법에서 반응기 내의 용존산소의 농도와 미생물에 의한 폐수처리 정도는 서로 밀접한 연관성을 가지므로 반응기내의 용존산소의 농도를 측정하는 것이 필요하다.Since the concentration of dissolved oxygen in the reactor and the degree of wastewater treatment by microorganisms are closely related to each other in the activated sludge process or the oxygen activated sludge method, it is necessary to measure the dissolved oxygen concentration in the reactor.
그런데 종래에는 용존산소를 측정하기 위해서는 측정전극(9)을 반응기 내부에 있는 유기성 폐수속에 집어 넣은 상태에서 측정해야했기 때문에 악취와 함께 심하게 오염된 폐수속에 측정전극을 설치하여 측정해야 하므로 별도의 보관장치나 조치가 필요하였고, 미생물을 활성화하여 폐수를 정화하기 위해서는 기포확산기(15)를 통해 다량의 공기방울을 반응기 내부에 공급해야 하므로 정화과정에 따른 슬러지의 발생 유속에 의한 와류현상으로 인하여 부정확한 측정이 유발되는 문제점이 있었다.However, conventionally, in order to measure the dissolved oxygen, the measuring electrode 9 had to be measured in the state of being put into the organic wastewater inside the reactor. In order to purify the wastewater by activating microorganisms, a large amount of air bubbles must be supplied into the reactor through the bubble diffuser (15). Therefore, inaccurate measurement due to the vortex caused by the sludge generation flow rate during the purification process There was a problem that was caused.
따라서 본 고안은 상기의 문제점을 해소하여 반응기 내부의 방해요인으로부터 영향을 받지 않기 위해 반응기외부에서 용존산소의 농도를 측정하여 정확성이 뛰어나면서도 측정전극의 유지관리가 간편한 측정캡을 제공함에 그 목적이 있다.Therefore, the present invention solves the above problems and measures the concentration of dissolved oxygen outside the reactor in order not to be influenced by disturbances in the reactor, and thus provides a measuring cap with excellent accuracy and easy maintenance of the measuring electrode. have.
상기한 목적에 따라, 본 고안에 있어서는 상면이 막혀있고 하면이 뚫려있는 원통형의 몸체(4)에 반응기(14)와 연결하기 위한 관통볼트(13)가 형성된 유입구(1)와 측정홀(7)로부터 폐수유출을 조절하기 위한 유량조절밸브(3)가 부착된 배출구(2) 및 측정홀(7)내부에 측정전극(9)을 고정시키기 위하여 고무링(8)이 측정홀 내부에 형성된 것을 특징으로 하는 용존산소 측정캡이 제공된다.According to the above object, in the present invention, the inlet 1 and the measuring hole 7 formed with a through-bolt 13 for connecting the reactor 14 to the cylindrical body 4 with the upper surface blocked and the lower surface opened. A rubber ring 8 is formed inside the measuring hole to fix the measuring electrode 9 in the outlet 2 and the measuring hole 7 with the flow control valve 3 for controlling the wastewater discharge from the water. A dissolved oxygen measuring cap is provided.
이하 첨부도면을 참조하여 본 고안을 상세히 설명한다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.
제2도에서 원통형 몸체(4)의 상부의 외주벽을 관통하여,형의 유입통로(5)가 형성된다. 유입통로(5)의 입구부분에는 반응기(14)와 연결하기 위해 유입구(1)를 갖는 관통볼트(13)가 설치된다. 유입통로(5)가 형성된 몸체(4)의 타방에는형의 배출통로(6)가 형성되고 배출통로(6)에는 측정홀(7)로부터 배출되는 폐수의 양을 조절하기 위한 유량조절밸브(3)가 부착된 배출구(2)가 연결된다. 관통볼트(13)와 유입통로(5)가 접속되는 부분 및 배출구(2)와 배출통로(6)가 접속되는 부분의 각각에는 폐수의 누출을 방지하기 위해 패킹(10)이 고정된다. 원통형 몸체(4)의 하방에는 츠정전극(9)을 삽입하기 위한 측정홀(7)이 형성되고, 유입통로(5)와 배출통로(6)의 일단부가 측정홀(7)에 통하고 있다. 측정홀(7)의 내주벽에는 측정홀(7)에 삽입된 측정전극(8)을 보다 견고히 고정함과 아울러 유입통로(5)를 거쳐 측정홀(7)의 내부로 유입되는 폐수가 측정전극(9)과의 틈새를 통해 누출되지 않도록 하기 위해 고무링(8)이 설치된다.Through the outer circumferential wall of the upper portion of the cylindrical body 4 in Figure 2, An inflow passage 5 of the mold is formed. Inlet portion 5 of the inlet passage (5) is provided with a through bolt 13 having an inlet (1) for connecting with the reactor (14). On the other side of the body 4, the inflow passage 5 is formed A discharge passage 6 of a type is formed, and the discharge passage 6 is connected to a discharge port 2 having a flow control valve 3 for controlling the amount of wastewater discharged from the measurement hole 7. The packing 10 is fixed to each of the portion through which the through bolt 13 and the inflow passage 5 are connected and the portion through which the discharge port 2 and the discharge passage 6 are connected. A measuring hole 7 for inserting the positive electrode 9 is formed below the cylindrical body 4, and one end of the inflow passage 5 and the discharge passage 6 passes through the measurement hole 7. The measuring electrode 8 is more firmly fixed to the inner circumferential wall of the measuring hole 7, and the wastewater introduced into the measuring hole 7 through the inflow passage 5 is measured. A rubber ring (8) is provided to prevent leakage through a gap with (9).
제3도는 본 고안에 따른 측정캡의 측정홀(7)에 측정전극(9)이 삽입된 상태를 도시하는바, 유량조절밸브(3)를 잠구어 놓은 상태에서 용존산소의 농도를 측정하게 되면 측정홀(7)내에서 폐수의 유동이 없으므로 반응기내의 용존산소의 농도에 대한 변화량을 반응기 밖에서 정확하게 알 수 있고 이와 같은 연속측정에 따른 측정치를 측정전극(9)에 연결된 디스플레이장치에 의하여 눈으로 확인할 수 있다.Figure 3 shows a state in which the measuring electrode 9 is inserted into the measuring hole 7 of the measuring cap according to the present invention, when measuring the concentration of dissolved oxygen in the state that the flow control valve 3 is closed Since there is no flow of wastewater in the measuring hole 7, the amount of change in the concentration of dissolved oxygen in the reactor can be accurately known outside the reactor, and the measured value according to such continuous measurement is visually confirmed by a display device connected to the measuring electrode 9. Can be.
상기한 측정과정을 설명하면, 먼저 몸체(4)의 측면에 부착된 호스연결용 관통볼트(13)를 측정대상의 폐수가 들어 있는 반응기의 호스에 연결하면 측정대상의 폐수는 관통볼트(13)를 통해 유입통로(5)를 지나 측정홀(7)로 들어가데 된다. 이 때 측정폐수는 유입통로(5)의부분에서 유속이 완만해지므로 와류현상이 않은 채 측정홀 내부로 유입되는 것이다.Referring to the above-described measurement process, first connecting the through-bolt for connecting the hose 13 attached to the side of the body (4) to the hose of the reactor containing the waste water of the measurement object wastewater of the measurement object through the bolt (13) Through the inflow passage (5) through and enters the measuring hole (7). At this time, the measured wastewater is As the flow velocity becomes slow in the part, it flows into the measuring hole without vortex.
이에 따라 측정홀(7)에 들어있던 공기는 측정홀 상단까지 측정대상의 폐수가 충만되면서 배출구(2)를 통해 배출된다.Accordingly, the air contained in the measuring hole 7 is discharged through the outlet 2 while the waste water of the measuring object is filled up to the upper end of the measuring hole.
따라서 측정홀(7)에 유입된 폐수에 대한 용존산소의 농도측정은 연속적으로 원할때마다 측정전극에 연결된 스위치를 단락시킴으로서 측정될 수 있다.Therefore, the measurement of the concentration of dissolved oxygen in the wastewater introduced into the measuring hole 7 can be measured by shorting the switch connected to the measuring electrode continuously whenever desired.
측정홀(7)로부터 폐수를 급속히 배출하는 것은 용존산소의 농도값이 오차를 가질 수 있으므로 이를 방지하기 위해 배출통로(6)의부분의 높이를 유입통로(5)의부분의 높이와 일치시키고 측정시 유량조절밸브(3)를 잠구어 측정홀(7)에서 측정폐수의 유동이 없도록 함으로써 측정값의 정확도를 향상시킨다.Rapidly discharging wastewater from the measuring hole 7 may have an error in the concentration of dissolved oxygen so that the discharge passage 6 may be Height of the inlet passageway (5) The accuracy of the measured value is improved by matching the height of the part and closing the flow control valve 3 during the measurement so that there is no flow of the measurement wastewater in the measurement hole 7.
이상의 설명에서와 같이 본 고안에 따른 용존산소 측정캡은 간편한 조작을 통해 반응기 외부에서 측정대상의 폐수에 대한 용존산소의 농도를 측정하는 것으로, 반응기 외부에서 측정이 이루어지므로 측정전극을 관리, 보관하는 것이 용이할 뿐만 아니라 신속하면서도 정확한 측정값을 파악할 수 있는 효과가 있는 것이다.As described in the above description, the dissolved oxygen measuring cap according to the present invention measures the concentration of dissolved oxygen in the wastewater of the measurement target through a simple operation outside the reactor. Not only is it easy, but it also has the effect of being able to identify fast and accurate measurements.
