With the improvement of people’s living standards, people pay more and more attention to the water quality! In the case of more and more serious environmental pollution, how to know the situation of water pollution? This chapter water quality online monitoring instrument manufacturers to understand together with you whether fish can detect water pollution!

It is necessary to use the water quality monitor to detect the sewage in real time, of course, if there is no such instrument, can you use fish to monitor the pollution of the water quality? The answer is: Yes!

Because the fish that survive in the polluted water source (especially some fish that are very sensitive to water pollution) will have some abnormal behavioral symptoms, such as: climbing bass living in fresh water, appearing from the water and land, which is caused by the lack of oxygen in the water quality, and the carp in the pond, water pollution has led to its deformity. It can be seen that observing the growth of fish in the water can determine whether the water quality is healthy!

If the COD content in the water is very high, it is easy to reduce the oxygen in the water, which will cause hypoxia, making the fish breathe more difficult, and seriously cause the death of the fish. In addition, the short-term impact of ammonia nitrogen and total phosphorus nitrogen on fish is not large, but it will cause secondary pollution “photosynthesis” in the long term, thus forming COD. Of course, the content of the major indicators in the water is within the standard range, it does not matter! This requires the use of COD-8000- COD online analyzer to monitor the content of COD in water. Of course, the indicators in sewage are not only an indicator of COD, which requires sampling to see what the specific indicators are, and then targeted online monitoring of water quality.
