摘要
评估了现有水体除氟技术,重点探讨了吸附法的应用潜力与发展前景。综述了混凝沉淀、电化学、离子交换、膜处理和吸附法等多种技术,突出吸附法在操作简便、成本较低和应用广泛等方面的优势。选取铝基、黏土、生物质和碳基等多种吸附材料,分析了其除氟表现,并结合实验与模拟,探讨了pH、温度、吸附剂投加量等因素对吸附氟的影响。结果显示,铝基和碳基吸附剂在效率和经济性上具有明显优势。
This study aims to systematically evaluate existing fluoride removal technologies in water,with a focus on the potential and prospects of adsorption methods.A comprehensive literature review compared various techniques such as coagulation-precipitation,electrochemical methods,ion exchange,membrane filtration,and adsorption,highlighting the advantages of adsorption in terms of simplicity,low cost,and broad applicability.Several adsorbent materials,including aluminum-based,clay,biomass,and carbon-based materials,were selected for in-depth analysis of their fluoride removal performance.The study also explored key factors influencing adsorption efficiency,such as pH,temperature,and adsorbent dosage,through experiments and simulations.Results indicate that aluminum-based and carbon-based adsorbents demonstrate significant advantages in both efficiency and cost-effectiveness.This evaluation provides valuable insights for optimizing existing technologies,improving water treatment efficiency,and addressing global fluoride pollution issues.
