【Abstract】 Due to the coupled effects of the properties of minerals and the advantages offered by composite materials, mineralbased composite materials have exhibited unique performances and attracted significant attention in the field of ecoenvironmental studies with extensive applications in improving water quality. This paper reviews various methods for enhancing the structure and properties of mineral-based composites materials, including acid/alkali etching, thermal activation modification, surface modification, and metal nanoparticle load modification. The mechanisms of these materials in effectively fixing/removing heavy metals, organic and inorganic pollutants in the aquatic environmental pollutants include adsorption,catalytic reactions, and synergistic effects with aquatic organisms such as microorganisms and aquatic plants. Mineral-based composite material plays a vital role in advancing biological ecological restoration, promoting the growth of aquatic plants, and enhancing microbial diversity. And the paper summarizes application cases of mineral-based composite materials in water environment restoration and management, and emphasizes the focus of future research on assessing their performance and longterm effects in different water quality environments, exploring best approaches of their joint application with other advanced techniques, and optimizing their manufacturing processes and material costs.
