Description

{Automatic water quality measurement method to automatically manage quality control solution and standard solution, and water quality automatic measuring device for performing thereof}

The present invention relates to an automatic water quality measurement method, and more particularly, maintains the accuracy of water quality measurement through a quality control solution and a standard solution, and automatically manages the quality control solution and standard solution to automatically detect abnormalities. It relates to an automatic water quality measurement method and an automatic water quality measurement device for performing the same.

For water quality management, we established a water quality remote monitoring system (TMS) that can scientifically measure the level of pollution and discharge of wastewater, and have business sites attach an automatic water quality meter to measure the concentration of pollutants emitted at all times. In addition, by exempting business site visits and inspections for discharge sites, the transparency and efficiency of guidance and inspection work can be enhanced. Furthermore, the government is promoting “remote water quality monitoring” in order to scientifically and rationally promote the total amount of water pollution management system. System (TMS) construction project” is being promoted.

The water quality remote monitoring system (TMS) is a system that reduces water pollution in advance by remotely managing pollutant emissions from the source unit. It is essential for managing pollutant emissions more systematically and efficiently and at the same time laying the foundation for environmental informatization. When the water quality remote monitoring system (TMS) is established, it is possible to create an environmental informatization system that can comprehensively manage water pollution across the country by establishing a shared system among the Ministry of Environment, local governments, and wastewater discharging businesses by using the automatic water quality measurement data as a database .

Water quality TMS requires that automatic measurement equipment be maintained and managed normally at all times because automatic measurement data is immediately transmitted to the control center and used as administrative data. should have In case the data is not transmitted to the control center due to invalid data due to inspection of the measuring device or temporary abnormality of the measuring device, even though the emission and prevention facilities are operating normally, invalid data for use in statistical analysis or total amount calculation There may be cases where it is necessary to create an alternative material to replace the . Therefore, if the equipment is well managed and invalid data is not produced, disadvantages and disputes that may occur when generating substitute data can be reduced.

The automatic water quality meter in operation should undergo regular quality inspection to maintain the reliability of measurement data, and methods and procedures for conversion formula management through periodic calibration should also be established. The control center not only collects measurement data, but also analyzes trends by business site through statistical analysis of measurement data to provide technical support for the status and calibration of measuring devices. By distributing it to the operation manager, it is used as a guideline for the operation of automatic measuring instruments. A technology related to such an automatic water quality measurement device is disclosed in 'Patent Document 1'.

Some of the continuous automatic water quality measuring instruments are quality controlled according to the water pollution process test standards. For continuous automatic measuring instruments in the water pollution process test standards, the Korea Environment Corporation visits the site once a year and continuously monitors them in the name of quality inspection and integrated inspection. The quality control of such a water quality measurement device requires repeated measurement operations several times, and a manager must continuously reside and manage the measurement while the repeated measurement is performed. In other words, quality control can be performed only when the manager repeats the dilution, manufacture, and input of the sample required for the repeated operation of quality control. In the case of measuring devices that take a long time to analyze, it may take several days, raising the problem of wasting manpower.

In particular, in the case of total organic carbon, total nitrogen, and total phosphorus measuring instruments, if the sample is continuously measured due to the characteristics of the measuring instrument, contamination accumulates inside the instrument and the measurement result is biased. When checking the status, there is a problem in that it is inefficient and the management status of the measuring device varies depending on the user.

The terms or words used in the present specification and claims conform to the technical idea of the present invention based on the "principle that the inventor can appropriately define the concept of a term in order to best describe his invention" It should be interpreted as the meaning and concept that

Therefore, the embodiments described in this specification and the configurations shown in the drawings are only the most preferred embodiments of the present invention, and do not represent all the technical ideas of the present invention, so various equivalents that can replace them at the time of the present application It should be understood that there may be water and variations.

The first step is to measure the quality control solution.

The second step is a step of confirming whether the result of the first step is within the allowable range set by the user. The permissible range of the quality control solution can be set arbitrarily by the user, but preferably a standard standard is set.

In step 3-1, if the result of step 2 is measured within the allowable range, the quality control solution is expected to be in a normal state, so the water quality of the target sample is measured.

Step 3-2 is a step to prepare a calibration curve by measuring the standard solution when the result of step 2 is out of the allowable range.

Steps 3-1 and 3-2 are selectively performed according to the result of step 2, and if step 3-1 is performed, subsequent steps are interrupted and the process returns to step 1.

The fourth step is to check whether the calibration curve prepared in step 3-2 is within the allowable range compared to the existing calibration curve. The allowable range of the calibration curve can be set arbitrarily by the user, but preferably a standard standard is set.

In step 5-1, if the result of step 4 is within the allowable range, trust the state of the standard solution and replace the newly created calibration curve with the existing calibration curve. In this case, too, the quality control solution is expected to be in a normal state, so the water quality of the target sample is measured.

Step 5-2 is a step of maintaining the existing calibration curve and sending a notification signal when the result of step 4 is out of the allowable range. In this case, the notification signal is a signal sent to the person in charge or the manager of the automatic water quality measurement device, and may use a notification through an application, a web-based notification, or a mobile text message notification through SMS.

Steps 5-1 and 5-2 are selectively performed according to the result of step 4, and if step 5-1 is performed, subsequent steps are stopped and the process returns to step 1.

Specifically, the first step, step 1-1 measuring the weight before use of the standard solution / quality control solution; And it is configured to include a step 1-2 of measuring the weight of the standard solution / quality control solution after use.

The second step is to derive the difference between the weight of the standard solution/quality control solution measured in step 1-1 and the weight of the standard solution/quality control solution measured in step 1-2, and then based on this, the number of times or period that can be used Step 2-1 of calculating and a step 2-2 of determining whether the calculated value is within a set value.

In step 3-1, when the result of step 2-2 is measured within the allowable range, the available number of times or period is stored in the menu inside the device. If step 3-1 proceeds, it may be terminated as it is, but step 1-2 may be restarted to continuously check the status of the standard solution/quality control solution.
