- Аннотация: In order to explore better treatment process of oily sludge, the field scale experiments were conducted using the sludge containing 12.68% oil. The performance of microbe preparation bio-augmentation (MPB) and compost treatment with manure (CTM) was compared. For the first experiment, 10 L solution containing 150 g microbe preparations and the nutrition were sprayed onto the MPBC cell. The initial oil content of final mixture amounted to 12.12%. The initial oil content of CTM after final mixture approximated to 10.14%. During the experimental period, same quantities of the microbe preparation and nutrient solution were sprayed on MPB at the 15th and 30th day separately. At the same days, the 10 kg manure was added to CTM cell. The degradation effect of MPB was more obvious, oil content dropped to 6.42% with a 47% removal rate of oil. The oil content in control decreased slightly to 10.15% after 56 days, while in CTM it fell down to 6.98% with a total removal rate of 31%. The pH in control fluctuated slightly between 8.28 to 7.93 while that in MPB, from 7.33 to 8.08, which might due to the addition of microbe preparation. The microbial count was analyzed weekly, which represented the adaptation ability of microbe in sludge. Temperature of compost increased rapidly up to 54 degrees C in the presence of manure. The differences of two kinds of methods were identified by GC-MS and the hydrocarbons with less 21 carbons were degraded easily.
