含油污泥脱水萃取工艺研究
|
摘要
针对辽河油田浮渣底泥进行了特性分析及萃取工艺优化实验。对不同含水率的含油污泥进行萃取实验,分析含油污泥中水分对萃取过程的影响,确定适宜含油污泥萃取的含水率区间为20.0%~30.0%。适宜的萃取条件为:剂泥比(质量)为2∶1,萃取温度50℃,萃取时间30 min,在此优化条件下,含油污泥油分萃取率>65%。
The characteristics analysis and solvent extraction process optimization were conducted for the oily sludge formed in the sewage treatment plant. The extraction experiment of oily sludge with different water content was carried out to analyze the influence of water on extraction process,and the suitable range of water content for oily sludge extraction was 20. 0% ~ 30. 0%. The optimized extraction conditions were time 30 min,temperature 50 ℃,solvent/sludge mass ratio 2,under which more than 65% oil could be extracted.
