摘　　要：以城市污水处理厂二级生物处理出水地下回灌为回用目的，研究了活性炭吸附深度处理工艺。通过静态吸附试验选定了适于处理二级出水的粒状活性炭，并运用ＡＤＳＡ 软件对有机物在活性炭上的吸附行为进行了分析。将活性炭吸附同混凝砂滤相结合，研究两种不同组合工艺对有机物的去除效果，筛选出了适于城市污水处理厂二级出水地下回灌的深度处理工艺，再生水中以ＤＯＣ 表征的有机物浓度可达３ｍｇ／Ｌ～４５ｍｇ／Ｌ以下。An advanced treatment technology of activated carbon adsorption(ACA)to treat the secondary effluent of municipal wastewater plant for groundwater rercharge was studied.The granular activated carbon,which is optimally suitable for municipal wastewater was chosen by isotherm adsorption experiments and adsorption behaviors of organic pollutants on different kinds of activated carbons were analyzed with ADSA program.Two different combined processes consisted of coagulation.sand filtration and ACA were conducted to investigate the removal efficiency of organic contaminants,through which the suitable advanced treatment process was selected and DOC value of the effluent could be decreased to less than 3～4.5 mg/L.
