Description

technical field [0001] The invention belongs to the technical field of environmental adsorption materials, and in particular relates to an environment-friendly adsorption material and a preparation method for efficient phosphorus removal of clay / pyrolulurite. Background technique [0002] With the development of economy and society, the problem of eutrophication of water body is becoming more and more prominent, water quality is deteriorating, and algae grows wildly, seriously endangering aquatic ecosystem and human health. Excessive discharge of phosphorus is the main cause of water eutrophication. Therefore, effectively reducing the content of phosphorus in discharged wastewater has become an important way to prevent and control water eutrophication. [0003] At present, the commonly used methods for phosphorus removal mainly include biological methods, chemical precipitation methods, electrolysis methods, and adsorption methods, among which the adsorption method is an eff...
