The aim of this study was to explore a more effective treatment method to improve the quality of polluted river water by studying different river water treatment processes and the influence of heavy metals on their treatment effects.In this study, we will use various treatment processes such as biological treatment, chemical treatment and physical treatment to treat river water. We will compare the treatment effects of these processes and analyze the differences and reasons. At the same time, we will explore the influence of heavy metals on these treatment processes to determine the mechanism of heavy metals on the treatment effect of river water.精品文档---下载后可任意编辑Through this study, we will draw the following conclusions: first, different river water treatment processes have obvious differences, and the most suitable process should be selected according to the actual situation; second, different heavy metals have different effects on the treatment effect, and should be treated separately; finally, by combining the advantages of various processes, a high-efficiency and adaptable river water treatment process can be designed.【Key words】river water；water treatment process；heavy metal; treatment effect; environmental problem
