With the continuous improvement of environmental protection awareness, water quality monitoring has attracted more and more attention. However, there are many technical problems in the actual water quality monitoring work, which not only affect the accuracy of the monitoring results, but also restrict the further development of water quality monitoring. In this paper, we will discuss the technical problems and countermeasures in water quality monitoring.
1. Technical issues in water quality monitoring.
1.Water quality sampling issues.
Water quality sampling is the basic work of water quality monitoring, and its quality is directly related to the accuracy of monitoring results. In practice, there are the following problems in water quality sampling: first, the sampling points are inaccurate, resulting in the unrepresentative water samples collected;Second, the sampling frequency is insufficient, which cannot fully reflect the changes in water qualityThird, the sampling method is not standardized, resulting in contamination or destruction of water samples.
2.Problems with detection methods.
Water quality monitoring requires the use of appropriate testing methods to ensure the accuracy of monitoring results. However, in practice, the detection method has the following problems: first, the scope of application of the detection method is limited, which cannot meet the monitoring needs of a variety of water quality indicators;Second, the sensitivity of the detection method is insufficient, resulting in the inability to detect low-concentration pollutants;Third, the operation of the detection method is cumbersome, which affects the monitoring efficiency.
3.Problems with instrumentation and equipment.
Instruments and equipment are important tools in water quality monitoring, and their quality directly affects the accuracy of monitoring results. In practice, there are the following problems in the instrumentation and equipment: first, the accuracy of the instrument and equipment is not enough, resulting in a large error in the monitoring results;Second, the maintenance of instruments and equipment is not in place, resulting in equipment damage or performance degradation;Third, the upgrading of instruments and equipment is not timely, which cannot meet the new monitoring needs.
2. Coping strategies.
In view of the above technical problems, the following countermeasures are proposed:
1.Establish a sound water quality sampling system.
Establishing a sound water quality sampling system is the key to solving the problem of water quality sampling. First of all, it is necessary to clarify the sampling point and frequency to ensure that the collected water samples are representativeSecondly, the sampling method should be standardized to avoid contamination or destruction of water samplesFinally, it is necessary to strengthen the training and management of sampling personnel, and improve the quality and sense of responsibility of sampling personnel.
2.Optimize your detection methods.
In view of the problems existing in the detection method, the research and optimization of the detection method should be actively carried out. First of all, it is necessary to expand the scope of application of detection methods to meet the monitoring needs of various water quality indicatorsSecond, the sensitivity of the detection method should be improved to detect contaminants at low concentrationsFinally, it is necessary to simplify the operation process of the detection method and improve the monitoring efficiency.
3.Strengthen the management and maintenance of instruments and equipment.
The management and maintenance of instruments and equipment is an important part of water quality monitoring. First of all, it is necessary to strengthen the accuracy management of instruments and equipment to ensure the accuracy of monitoring resultsSecondly, it is necessary to establish a sound instrument and equipment maintenance system, and regularly inspect and maintain the equipmentFinally, it is necessary to update the instruments and equipment in time to meet the new monitoring needs.
III. Conclusion. Water quality monitoring is an important part of environmental protection, and the solution of technical problems is of great significance to improve the accuracy of monitoring results. Through the implementation of coping strategies such as establishing a sound water quality sampling system, optimizing detection methods, and strengthening the management and maintenance of instruments and equipment, the technical problems in water quality monitoring can be effectively solved and strong support can be provided for the development of environmental protection.
