[给水排水工程论文] 摘要: 本文在小试的规模下,研究了PET 管式自生动态膜生物反应器在处理垃圾渗滤液时的运行特性。研究表明,反应器连续运行50 天,过滤压差维持在30cm,膜出水通量3.75L/m2•h 左右,文章分析了膜通量不高的原因。尽管通量较低,但系统运行稳定,符合生物反应器在处理高浓度有机废水的特点,COD 和氨氮的平均去除效率分别达到69%和98%以上。 关键字: 管式自生动态膜 膜生物反应器 垃圾渗滤液 膜通量 过滤压差 The lab scale research on tubular self-forming dynamic membrane bioreactor in treatment of landfill leachate Dong Chunsong, Fan Yaobo, Li Gang (Research Center for Eco-environmental Science, Chinese Academy of Sciences, Beijing 100085) Abstract: The operating performance of PET tubular self-forming dynamic membrane bioreactor (DMBR) in treatment of landfill leachate on laboratory scale was studied. The result showed that the filtration pressure maintained at 30cm for 50 days, the flux was 3.75L/(m2·h). The possible reasons about the low penetrability were analyzed in this paper. Although the flux was low, the system was operated steadily, which was consistent with the character of bioreactor when dealing with high concentration organic wastewater. The average emoval rate of COD andNH4+-N in this system both exceeded 69% and 98% respectively. Keywords: tubular self-forming dynamic membrane; membrane bioreactor; landfill leachate; membrane flux; filtration pressure……
