摘　　要：在原水水质持续改善和饮用水标准不断提升的双重背景下,优化常规工艺是经济有效的提质方法。此研究通过中试规模滤柱装置模拟实际滤池操作,系统分析了不同炭层厚度对COD_(Mn)和2-MIB等关键水质指标的去除效果。结果表明,炭层厚度设置为0.5 m~1.0 m,炭砂滤池能够有效发挥吸附和生物降解的双重作用,实现稳定且高效的水质净化效果。SEM和生物量分析验证了炭层上部生物膜的高活性对污染物去除作用。合理设置炭砂滤池中活性炭层的厚度,可有效提升水质净化效率,为水厂工艺改造提供了理论依据和技术支持。Amidst the continuous improvement of raw water quality and the ever-increasing standards of drinking water,optimizing conventional processes is an economical and effective method for quality enhancement.This study utilized a pilot-scale filter column setup to simulate actual filter operations,systematically analyzing the impact of various activated carbon layer thicknesses on the removal of key water quality indicators such as COD_(Mn)and 2-MIB.The results indicate that setting the activated carbon layer thickness to 0.5~1.0 m enables the GAC filter to effectively exert dual functions of adsorption and biodegradation,achieving stable and efficient water purification.SEM and biomass analysis confirmed the high activity of the biofilm on the upper part of the activated carbon layer in pollutant removal.Properly setting the thickness of the activated carbon layer in GAC filters can significantly enhance water purification efficiency,providing theoretical support and technical guidance for water plant process upgrades.
