River water quality online monitoring system requirements

The river water quality online monitoring system can analyze whether the water quality flowing into the river meets the discharge requirements for a long time, and can present the monitoring data through curve drawing and other methods. However, we will be limited by various environmental factors when installing the river water quality online monitoring system. And when choosing this device, you need to follow certain requirements, and I will introduce it to you today. River water quality online monitoring system requirements 1. The selected river water quality online monitoring system should be based on advanced, forward-looking and openness, and can be realized through advanced software and hardware technologies to ensure that the equipment structure can also operate normally after a few years . 2. The equipment design method needs to follow the sampling method and water quality treatment method stipulated in the standard, and no equipment other than the standard sampling method shall be added. 3. The analysis process of the river channel water quality online monitoring system is relatively simple, the investment cost is low, the wiring needs to be reasonable and clear, and the selected piping materials should satisfy the long-term stable operation of the system. 4. It should be ensured that when the river water quality online monitoring system is powered on again, the water collection unit, control system, monitoring software and other devices can automatically resume operation, ensuring that they can continue to operate for more than 4 hours. 5. It can be operated in continuous, interval and emergency operation modes, and the monitoring frequency can be set according to the monitoring site or remote control situation. 6. System design, water pumps, and piping devices should be selected according to the principle of a complete system. The total water volume of the water collection unit should be able to meet the water requirements of multiple monitoring devices, and due consideration should be given to possible additional analytical instruments. 7. When pre-treating water samples, certain impurities in the water should be filtered and it is necessary to ensure that the representativeness of the water samples is not changed. 8. The river channel water quality online monitoring system adopts mature methods, stable performance, low operating cost and small maintenance. The measurement lower limit and range meet the water quality requirements of the monitoring points, so an analytical instrument that does not discharge pollutant waste liquid should be selected as much as possible. 9. For the discharged waste liquid that does not meet the environmental protection requirements, it is necessary to adopt the correct treatment method according to the standard. 10. The power supply system device needs to be installed with a lightning protection device to ensure the stable operation of the power supply system, and it is also necessary to install a lightning protection device on the communication device. 11. The river water quality online monitoring system has a high degree of automation, which can realize automatic adoption, automatic pretreatment and blowback, automatic analysis and automatic cleaning, and automatic recording of output data, etc. 12. The selected equipment should have the function of self-starting when the call comes. 13. Complete design instructions and design drawings must be provided when installing the system, and corresponding communication protocols should be adopted for different types of equipment. The above is the introduction to the requirements of the river water quality online monitoring system. Different types of equipment may have some differences in actual requirements, so we should clarify what requirements it requires before installing the equipment correctly.
