| 摘 要：探討了高比表面積活性炭(HSAAC)吸附水中苯酚時(shí),活性炭用量、pH值和吸附時(shí)間等因素對苯酚吸附量和去除率的影響。實(shí)驗結果表明,HSAAC用量越大,去除效果越好。當HSAAC用量為0.2g.L-1時(shí),去除率達94%以上;在酸性條件下HSAAC對苯酚的去除效果較好,當pH值小于6時(shí),HSAAC對苯酚的去率可達95%以上;HSAAC對廢水中苯酚的吸附主要發(fā)生在前十幾小時(shí);活性炭對苯酚的吸附量和殘余質(zhì)量濃度均隨廢水中苯酚濃度的增加而增加。用堿再生HSAAC,一次再生率達93.3%,二次再生率達到了86.7%,說(shuō)明高比表面積活性炭在適宜條件下對苯酚具有較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... |
