摘　　要：可吸附有机卤化物 (AOX)是人为污染的重要标志之一。北京高碑店污水处理厂二级出水中约 90 %的 AOX为可吸附有机氧化物 (AOCl)。研究了臭氧氧化、粒状活性炭吸附、粉末活性炭吸附 3种深度处理工艺对二级出水中 AOX的去除作用。臭氧的氧化反应最多可去除约 3 8%的 AOX;粒状活性炭床可运行 3 2 0 0床体积 ,吸附容量为 0 .14 mg AOX/g GH-16型活性炭 ;投加木质粉末活性炭 2 0 0 m g/L 及 2 5 mg/L 的聚合氯化铝 ,能去除 2 4.7%的AOX (adsorbable organic halogen) was an important signal of artificial pollution. In the secondary effluent of Gao Beidian Sewage Treatment Plant, about 90% AOX consisted of AOCl. Three advanced treatment processes including ozone oxidation, GAC (granular activated carbon) adsorption, PAC (powdered activated carbon) adsorption were studied for removing AOX. In ozone treatment process, the maximum removal efficiency of organic pollutants characterized by AOX was about 38%. GAC bed could run for 3200 bed volumes and the adsorption capacity was 0.14 mgAOX/g carbon. 24.7% AOX could be removed with the dosage of 200 mg/L PAC and 25 mg/L polyaluminum chloride coagulant.\;
