Some people might say that since the water in the river is flowing and it has its own self-purification ability, why is it still necessary to monitor the water in the river? Isn’t this unnecessary? Of course not! Keep reading and you’ll understand.

With the continuous improvement of people’s living standards and the continuous progress of society, the discharge of industrial and agricultural wastewater as well as domestic sewage has also increased. If these wastewater and sewage are directly discharged without treatment and then flow into rivers, it is obvious that they will pollute the originally clean rivers. If it seriously exceeds the self-purification capacity of the river water, Over time, it will naturally lead to pollution of the river water. In fact, many urban rivers have been seriously polluted, and the main sources are the several sources introduced above. Therefore, what we need to do is to solve the pollution problem of river water quality and restore the ecological and social functions of rivers. This can be said to be the key to ensuring the sustainability of cities.

Why is it Necessary to Monitor the Water in Rivers?

Online monitoring of river water quality is actually one of the important tasks in water resource protection, with the main purpose of preventing pollution. The water quality is monitored in real time through a water quality monitor, and the relevant data is obtained to determine the condition of the water body. In fact, when it comes to water quality monitoring systems, they are a means to reflect water environment technology and are of great significance to water environmental protection!

The main items of online monitoring of river water quality include: some indicators for monitoring algae, monitoring of nutrient salt values (actually ammonia nitrogen), organic matter (determining the content of organic matter in water by monitoring COD), as well as pH value, temperature, dissolved oxygen, turbidity, electrical conductivity, etc.
