【摘要】 采用人工配制的模拟含聚(聚丙烯酰胺,PAM)驱采出水为介质,在以好氧颗粒污泥为主体的实验型 SBR内研究了油田驱采出水中PAM的生物降解性能。结果表明,好氧颗粒污泥对含聚驱采出水有良好的适应性,在相同的水力停留时间下,PAM降解率比普通活性污泥高约40倍。驯化后的颗粒形态发生明显变化,粒径减小到0 6~1 0 mm。更多还原

【Abstract】 In this paper,synthetic wastewater from oil extraction was used to investigate the properties of biodegradation of polyacrylamide (PAM) by aerobic granules in SBR. The results showed that the glucose-fed aerobic granules could be adapted to the synthetic wastewater, the biodegradation ratio of PAM was 40 times higher than the activated sludge in the same HRT. Comparing with the inoculum, it could be seen that the morphology of PAM-granules changed a lot, and the diameter reduced to 0.6~1.0 mm.更多还原
