With the continuous development of industry, the discharge of domestic and industrial water bodies has been increasing, resulting in the precipitation of heavy metal ions, nutrients containing phosphorus, organic matter and other pollutants in the riverbed mud. In particular, after the plankton in the river absorbs phosphorus, its growth rate accelerates and its ability to compete for oxygen in the water is improved.
