摘要
针对抚顺页岩炼油污水中的高氨氮特点,结合现有生化系统,采用氧化钙作为碱源对传统吹脱法、间歇式曝气吹脱法、二级循环吹脱法、膜法及生化法处理页岩炼油厂高氨氮废水的效果进行了对比。结果表明,传统筛板吹脱系统处理效率最低,仅为84%。最高效率99.8%是现有SDN生化法实现的,但处理量低。RANS膜法处理效率达到了96%。
In view of the high ammonia-nitrogen characteristic in Fushun oil refining sewage of shale, and in combination with the current biochemical system, the paper takes the calcium oxide as the alkali source. At the same time, the paper treats the high ammonia-nitrogen sewage in oil shale refinery and makes the comparison between the effects by using the traditional blow-off method, intermittent aerated blow-off method, second-grade recycle blow-off method, membrane method and biochemical method. The result shows that the deamination efficiency for the traditional tray blow-off tower system is the lowest, at 84%. The top efficiency at 99.8% was achieved by SDN biochemistry method, but its handling capacity was comparably low. The handling efficiency of RANS membrane method was up to 96%.
