为提高微污染水源水的饮用水质安全性,采用弹性填料微孔曝气富氧生物接触氧化工艺处理受污染的某水源原水,进行了除微量有机化学污染物的比较研究。GC-MS分析表明,受污染原水经富氧生物处理后,有机化学污染物种类减少了65.1%,有机优先化学污染物种类减少60.0%。富氧生物处理工艺对原水中几种微量有机优先化学污染物的去除作用大小不同。 相似文献

A number of U‐shaped K2NiF4‐type oxide hollow fiber membranes based on (Pr0.9La0.1)2(Ni0.74Cu0.21Ga0.05)O4+δ (PLNCG) were successfully prepared by a phase inversion spinning process. The PLNCG hollow fiber membranes were then used to investigate the effect of CO2 concentration in both the sweep gas and the feed air on the oxygen permeation flux. With pure CO2 as the sweep gas and even 10% CO2 in the feed air, a steady oxygen permeation flux of 0.9 mL/min·cm2 (STP) is obtained at 975°C during 310 h, and no decline of the oxygen permeation flux is observed. XRD, SEM and EDS characterizations show the spent membrane still maintains the intact microstructure and perfect K2NiF4‐type phase structure without carbonate, which indicates that the U‐shaped PLNCG hollow fiber membrane is a very stable membrane under CO2 atmosphere and has great potential for the practical application in oxyfuel techniques for CO2 capture and storage.©2011 American Institute of Chemical Engineers AIChE J, 2012 相似文献

The fluid‐dynamic behavior of a circulating fluidized bed pilot plant for oxyfuel combustion was studied in a cold flow model, down‐scaled using Glicksman's criteria. Pressures along the unit and the global circulation rate were used for characterization. The analysis of five operating parameters and their influence on the system was carried out; namely, total solids inventory and the air velocity of primary, secondary, loop seal and support fluidizations. The cold flow model study shows that the reactor design allows stable operation at a wide range of fluidization rates, with results that agree well with previous observations described in the literature. 相似文献
