Abstract
With the development of industry, wastewater treatment has become a critical environmental protection issue. Ion exchange resins, due to their high-efficiency selective adsorption characteristics, have demonstrated unique advantages in the removal of heavy me tal ions and organic pollutants. This study aims to investigate the application effects and optimization strategies of ion exchange resins in different types of wastewater treatment. By comparing the performance differences of various resin materials and integrating practical engineering cases, this research systematically evaluates key parameters such as resin selectivity, regeneration capability, and service life. The experiments combined batch adsorption with dynamic column tests to examine the influence of factors like pH value, temperature, and flow rate on adsorption performance, establishing mathematical models to predict optimal operating conditions. Results show that ion exchange resins modified with specific functional groups exhibit significant selective adsorption capacity for heavy me tal ions such as copper, cadmium, and lead, with maximum adsorption capacities exceeding 35 mg/g. Additionally, novel macroporous structure resins showed excellent decolorization effects for organic dye wastewater, achieving removal rates over 90%. Through the study of the relationship between resin structure and performance, an optimization design concept based on molecular simulation technology was proposed, providing theoretical basis for developing high-performance environmentally friendly ion exchange materials. This research not only enriches the theoretical system of ion exchange but also offers practical technical solutions for advanced industrial wastewater treatment, possessing significant academic value and broad application prospects.
