The present invention relates to a multi-point continuous water quality measuring system, and provides a multi-point continuous water quality measuring system capable of continuously measuring water quality for each multi-pointer in real time in a wastewater treatment plant.

In a conventional wastewater treatment plant, various water quality items are measured and monitored at each step. To this end, a meter that measures water quality at each stage and various control devices that store, transmit, and visualize the measured value must be installed at points corresponding to each stage. In this case, not only a lot of cost is required, but also a lot of manpower is required to manage it.

In addition, since multiple measuring devices are located at multiple points with different surrounding environments, not only is maintenance difficult, but also aging progresses differently for each measuring device, and it is difficult to determine whether or not the measuring device itself is contaminated. As a result, a fatal problem occurs in which the reliability of the measured value is lowered.

Among the following descriptions, descriptions overlapping those of the above-described embodiments will be omitted. Also, the techniques described below can be applied to the foregoing embodiments.

7 is a diagram for explaining a multi-point continuous water quality measurement system according to a third embodiment of the present invention.

As shown in FIG. 7 , the multi-point continuous water quality measurement system according to the third embodiment includes a central sample measurement unit 100, a sample circulation unit 200, a reference solution storage unit 400, a control unit 500, and an optional measurement unit. A sample switching unit 300 having a unit 600, providing a sample from the sample circulation unit 200 to the central sample measuring unit 100, and providing the sample after measurement has been completed to the sample circulation unit 200 again. include

The sample switching unit 300 includes at least one connection pipe 310 connected to the at least one sample circulation unit 200, a reference connection pipe 320 connected to the reference solution storage unit 400, and at least one A central pipe 330 connected to the connection pipe 310, the standard connection pipe 320, and the chamber pipe 140, and a central pipe 330 connected to the at least one connection pipe 310 and the chamber pipe 140 At least one communication valve 340 communicating with the liver, a discharge pipe 380 connected to the sample circulation unit 200, and a discharge valve 390 communicating between the discharge pipe 380 and the central pipe 330 and a reference valve 350 communicating between the standard connection pipe 320 and the central pipe 330, and a drain valve 360 draining the central pipe 330. The sample switching unit 300 further includes a standard detection switch 370 installed in the standard connection pipe 320 .

Through this, it is possible to provide the sample for which the measurement has been completed to the circulation pipe 210 that has been introduced. Due to this, additional contamination by the measured sample can be prevented. At this time, it is effective that the discharge valve 390 and the discharge pipe 380 have the same configuration as the connection pipe 310 and the communication valve 340 . In addition, it is effective to prevent the sample from flowing back into the chamber by providing a backflow prevention device in the discharge pipe 380 .

Although the technical idea of the present invention described above has been specifically described in a preferred embodiment, it should be noted that the above embodiment is for explanation and not for limitation. In addition, those skilled in the art of the present invention will be able to understand that various embodiments are possible within the scope of the technical idea of the present invention.
