重金属、农药和抗生素污染的修复对于保护浅水湿地的生态环境具有重要意义。浅水湿地由于功能的独特性和生态的复杂性，传统的污染修复方式难以实现高效、绿色、稳定的修复效果。本项目通过表面修饰等技术在纳米粘土上负载光催化剂，制备具有可见光响应的光催化材料；以堆肥颗粒为核心，纳米粘土基光催化材料为裹覆材料，在粘结剂存在下制备纳米粘土-堆肥复合材料；研究复合材料对浅水湿地中重金属、农药、抗生素的吸附与解吸行为与机理及其在可见光下对农药与抗生素的降解效率和机理；通过不断地试验和反馈，筛选出同时对重金属、农药、抗生素的吸附能力强、对农药与抗生素的降解效率高的复合材料；通过对复合材料的环境风险评估、盆栽与实地试验等，形成能实际应用于受污染浅水湿地的修复剂及修复技术、方法和理论。本项目的研究成果可为浅水湿地的重金属、农药和抗生素污染的高效、低成本修复提供新思路、新模式和新技术。

The remediation of heavy metals, pesticides, antibiotics pollution are extremely important for protecting the ecological environment of shallow water wetlands. Due to the unique function and the complicated ecology of shallow water wetlands, the traditional pollution restoration method is difficult to achieve efficient, green and stable effectiveness. In this project, photocatalytic materials with visible light response were prepared by loading photocatalysts on nanoclays by techniques such as surface modification. Nanoclay/compost composites were prepared by using composting particles as the core and nanoclay-based photocatalysts as cladding materials in the presence of binder. The effects and mechanism of the composites on the adsorption and desorption of heavy metals, pesticides, antibiotics in shallow-water wetlands were studied. Moreover, the degradation efficiency and mechanism of pesticides and antibiotics under visible light were studied. Through continuous testing and feedback, composites with high adsorption capacity for heavy metals, pesticides, antibiotics, and high degradation efficiency of pesticides and antibiotics was selected. Through the environmental risk assessment, potting and field experiment of composite materials, the remedial agents, remediation techniques, methods and theories can be developed to be applied to the practical contaminated shallow water wetlands. The projectcan provide new ideas, new models and new technical approaches for the remediation of shallow water wetlands with high efficiency and low cost.
