| 摘 要： | 采用一种新型的颗粒生物膜生物转盘处理有机废水,将盘片改为转筒状,并向其中加入特制的多孔聚合物高分子载体,考察了该系统对COD和NH3-N的去除效果及多孔聚合物栽体的生物膜特性.结果表明,系统对COD和氨氮的去除效果较好,当进水COD和氨氮分别为(252～538)、(22.2～51.7)mg/L(平均值分别为386.6、33.0 mg/L)时,系统对COD和氨氮的去除率分别为63.6%～96.4%(平均为85.2%)、77.8%～98.7%(平均为86.5%);多孔聚合物高分子法载 体挂膜良好,平均膜厚为186.4μm.

| Abstract: | The improved rotating biological contactor was used to treat organic wastewater.The disks were changed into a rotation-cage-type,in which porous polymer carriers were added.The removal efficiencies of COD and NH3-N and the characteristics of biofilm formating on the carriers were investigated.The experimental results indicate that when the COD and NH3-N in the influent are 252 to 538 mg/L(average of 386.6 mg/L) and 22.2 to 51.7 mg/L(average of 33.0 mg/L),the removal rates of COD and NH3-N are 63.6% to 96.4%... |
