摘　要：探讨了高比表面积活性炭(HSAAC)吸附水中苯酚时,活性炭用量、pH值和吸附时间等因素对苯酚吸附量和去除率的影响。实验结果表明,HSAAC用量越大,去除效果越好。当HSAAC用量为0.2g.L-1时,去除率达94%以上;在酸性条件下HSAAC对苯酚的去除效果较好,当pH值小于6时,HSAAC对苯酚的去率可达95%以上;HSAAC对废水中苯酚的吸附主要发生在前十几小时;活性炭对苯酚的吸附量和残余质量浓度均随废水中苯酚浓度的增加而增加。用碱再生HSAAC,一次再生率达93.3%,二次再生率达到了86.7%,说明高比表面积活性炭在适宜条件下对苯酚具有较好的吸附性能和良好的再生效果。

Abstract：The adsorption effects of high-specific surface area activated carbon(HSAAC)on phenol in wastewater were discussed and the factors,such as the dosage of activated carbon, pH value, the adsorption time ,the removal rate and others, were reseasched . The results of the tests showed that the greater the dosage of HSAAC, the better the effect of the removal rate of phenol . When the dosage of HSAAC was 0.2g L~(-1) the removal rate reached above 94%. Under the acidity condition, the treatment showed a better eff...
