摘　　要：以硝基苯为水中有机污染物的代表,探索了活性炭的有效改性方法,并进一步研究了改性活性炭吸附硝基苯的过程中吸附时间、温度及pH对硝基苯吸附量的影响,结果表明硝基苯的去除率达99.811%,活性炭的吸附量为24.054 mg/g,处理后的废水达到国家三级废水排放标准。Take the nitrobenzene as orgnic contamination to explore effective modification methods of activated carbon,some operation parameters such as the adsorption time,temperature and pH were examined in the further study of the modified activated carbon adsorption of nitrobenzene.The results showed that the nitrobenzene removal rate is as more as 99.811 % and the adsorption capacity of activated carbon reach over 24.054 mg/g.the wastewater reach the third grade of national integrated wastewater discharge Standard.
