Description

Technical Field

[0001] The present invention relates to the technical field of detection devices, and in particular to a water quality analyzer. Background Art

[0002] Phosphorus dissolved in water is also caused by geological changes, but most of it comes from feces and urine. Phosphorus-containing substances such as livestock wastewater, factory wastewater, and fertilizers are commonly used indicators of total phosphorus to reflect eutrophication of water bodies. Generally, the phosphorus concentration in rivers and lakes in densely populated areas is high. Excessive nutrients such as nitrogen and phosphorus enter lakes, reservoirs, bays and other waters, prompting a large number of algae and other plankton to reproduce rapidly. As a result, not only will the rapid reproduction of algae make the water turbid and smelly, the transparency will decrease, and the sensory properties will deteriorate, but also these algae and other organisms will die and be decomposed by aerobic microorganisms, resulting in insufficient dissolved oxygen in the water, causing the death of fish and other organisms in large numbers. Therefore, the monitoring of total phosphorus concentration in water quality has become an important indicator for environmental monitoring. However, the structure of the existing water quality analyzer is relatively simple, and there is a lack of equipment for mixing and stirring water samples, which leads to uneven mixing of impurities in the water sample, thereby affecting the final analysis results of the water quality analyzer, and has certain defects. Summary of the invention
