摘　　要：选用单宁酸、腐殖酸、双酚A(BPA)及邻苯二甲酸二甲酯(DMP)为吸附质,对经强制放电再生后的1#和2#颗粒活性炭(GAC)进行再吸附试验,研究再生后活性炭对不同物质的再吸附能力。结果表明,不同活性炭再生后对单宁酸及腐殖酸的再吸附能力较高,使用半年的饱和炭再生后吸附能力基本都超过新炭,使用3年的炭再吸附能力也达到70%～80%;经再生后使用半年的活性炭对BPA和DMP再吸附能力恢复率都在90%以上,有的甚至超过新炭,使用3年后的再吸附恢复率达55%～70%。清洗再生炭比未清洗再生炭对单宁酸及腐殖酸再吸附效果有较大提高,而清洗再生活性炭对BPA及DMP的再吸附几乎无影响。Re-adsorption capacity of 1# and 2# spent granular activated carbon regenerated to different matter was analyzed ,1# and 2# carbon regenerated by forced discharge and tannin acid, humic acid, bisphenol A （BPA）and dimethyl phthalate（DMP） as adsorbates. The results demonstrated that annin acid and humic acid re-adsorption of GAC regenerated was high; redsorption of GAC used halfa year atter regenerated was above that of new carbon; Re-adsorption capacity of GAC used three years was 70%～ 80%;BPA and DMP re-adsorption of GAC used half a year after regenerated was over 90%, some even above new carbon; Re-adsorption capacity of GAC used three years was 55%～70%; annin acid and humic acid re-adsorption of GAC regenerated after cleaning was roach better than that of GAC regenerated without cleaning, but the effects of cleaning on BPA and DMP re-adsorption of GAC were little.
