The comprehensive water quality monitoring parameters comprise contributions of various water body chemical components, so that the content analysis is difficult to realize by a single electrochemical method, and the common determination method is a chemical analysis method, so that the automatic monitoring equipment for the water quality monitoring parameters has a complex structure, a large volume and single monitoring parameters, and can normally work only by being provided with a water sample pretreatment system such as precipitation and filtration and a chemical reagent waste liquid recovery treatment system.

In addition, the traditional automatic water quality monitoring station needs to be built in a specially designed large-floor-area land station house, and a water pump with large power and a water pipeline with large length are matched to introduce a water sample into the water sample pretreatment system from a monitoring site. The water quality monitoring station is the mainstream form of the domestic and foreign surface water pollution automatic monitoring station so far, but the water quality monitoring station is high in cost, difficult to construct and complex to maintain and difficult to be used for real-time water quality monitoring at a large-area water area far from the shore, so that the water quality monitoring station is prevented from being used as a basic component to form a large-scale water environment automatic monitoring network.
