In the sewage treatment process, accurate and real-time water quality monitoring plays a crucial role. Water quality monitoring mainly includes two processes of manual sampling and laboratory analysis. Manual sampling is generally carried out by professional technicians who regularly collect water samples from sewage pools, treatment plants and other links. The sampling process is complicated and inefficient. Due to equipment and space limitations, most sewage sampling points are fixed, and the collected water samples cannot accurately represent the sewage. After collecting the water samples, the technicians need to carry them to the laboratory for analysis, which not only consumes transportation costs but also needs to consider whether the water samples are contaminated during transportation. There are too many uncertain factors to accurately obtain the water quality of the sewage. SUMMARY
