3D打印智造三维石墨烯基磷选择性电极材料，实现污水深度处理高效磷回收

This project utilizes 3D printing technology to manufacture 3D graphene-based phosphorus-selective electrode materials, achieving efficient phosphorus resource recovery through electrochemical enhancement technology for secondary effluent of sewage treatment plants. The project involves fields such as material chemistry, intelligent manufacturing, physical chemistry, and electrochemistry. Scientific issues such as phosphorus selectivity sensitivity, adsorption-desorption mechanism, and process adaptation and regulation have become important aspects of promoting the development of this technology. Focusing on sewage deep treatment to improve effluent quality while building a phosphorus loss control system, this project explores the optimization of electrode micro-interface conditions and flow channels through 3D printing technology, further improving mass transfer efficiency and electrochemical performance, and enhancing the pseudo-capacitance properties and phosphorus recovery efficiency by loading phosphorus-selective metal oxides. The project systematically studies the functional development of high-performance carbon material carriers through modern intelligent manufacturing technology, builds three-dimensional graphene-based electrodes with phosphorus selectivity refinement, and has significant scientific value and practical significance for promoting deep treatment of sewage phosphorus recovery processes based on electrochemical enhancement methods. Additionally, it provides a theoretical and scientific basis for the construction of a phosphorus circulation system and the recovery of high-value-added products in synchrony with resource utilization for sewage treatment.
