摘　　要：采用自制的UASB反应器组装厌氧反应处理系统,以高浓有机废水为基质,在反应器内分别添加壳聚糖和颗粒活性炭,接种絮状污泥进行启动,研究壳聚糖和活性炭作用条件下的启动过程、污泥变化情况、有机负荷变化情况、CODCr去除率情况和系统VFA浓度变化情况.研究结果表明在反应器启动初期添加壳聚糖或颗粒活性炭物质,均有助于UASB的快速启动,启动完毕后反应器系统处理效率稳定,而且添加颗粒活性炭物质启动效果优于添加壳聚糖,对应用于指导实践操作有一定的积极作用.Through assembling the anaerobic reaction system with the home-made UASB reactors,inoculating with flocculent sludge, the process of start-up of UASB was researched with adding chitosan and particulate activated carbon respectively in high concentration organic wastewater treatment.Through contrast experiment, the start-up process, variation of the sludge, organic loading, removal rate of CODCr and VFA concentration was studied.The experimental result showed that adding chitosan or activated carbon in the initial stages could help to rapid-start-up of UASB, and the system treatment efficiency is stable. Moreover, the condition of adding particulate activated carbon was superior to that of chitosa,this would be positive role for the application in practical operation.
