| 英文摘要 |
| The paper gives a review on the research and developing situation about the process of oil from sludge by a lowtemperature thermo-chemical conversion. It is involved in the mechanism、kinetics、technological factors、flowage、equipments、environmental and economic features and so on. The technical characteristics of the process is a distillation process of the organics. The conclusion is that the maxium oil yield can be achieved under the temperature 450℃ and retention time 0.5 hour, the process is a net energy exportor, the final effluences of the process meet the current environmental standards, the treatment cost of the process is lower than the incineration process and the thermo-chemical technology used for the sludge treatment can be commercialized applied. Finally, the main equipments of the process have been appraised in a pilot scale test. |
