Abstract: The continuous expansion of industrialization has led to a sharp rise in the rate of water pollution, the quality of water bodies is declining, while the human demand for freshwater resources is increasing day by day. In the face of the complex and severe water pollution situation, a variety of water treatment technologies are rapidly developing. Functional materials as the basis for the development of water treatment technology, more and more attention. Various types of functional materials have unique advantages, and have different processing roles and effects in water pollution treatment, but there are also different defects. The purpose of this paper is to summarize the effective treatment effect of several types of functional materials in the field of industrial wastewater, to describe the advantages and disadvantages of several types of functional materials, and to look forward to the possible future direction of research and exploration.
