| 中文摘要 |
| 为了消除污染,资源回收利用,进行了用硫酸的催化炭化作用将石油炼厂废水污泥制做活性炭的研究。结果表明,在0.5-0.7MPa、150-170℃、pH1.7-1.8的条件下,用废硫酸可使废水污泥炭化分离出来,炭渣经用KHCO3活化制成粒状活性炭,其质量可达GB/T13804-92M级标准。 |
| 英文摘要 |
| The results from the study showed that the sulphuric acid may allow sludges in the wastewater to carbonize and then separate from the wastewater under the conditions of applied pressure of 0.5-0.7 MPa,temperature of 150-170℃ and pH of 1.7-1.8.The granular activated carbon can be produced using the carbon cinder carbonized from wastewater sludges by KHCO3 activation.The main quality indices of the product are better than GB/T 13804-92(China)secondary granular activated corbon. It was found thatcatalytical carbonification of.sludges is lower cost approach of treating wastewater sludges from oil refinery with waste acid. |
