研究以好氧膜生物反应器(MBR)处理城市垃圾渗滤液,以膜截留的有机物量的变化间接反映SMP在反应器中的积累情况,以及其对污泥活性和污泥混合液过滤性能的影响,结果表明,随着进水垃圾渗滤液可生化性由0.60降至0.28,MBR中被膜截留的有机物浓度由226.4 mg/L增加至504.0 mg/L,积累程度加剧,并会抑制污泥脱氢酶活性,对反应器中混合液过滤性能有负面影响.%The aim of the study on a landfill leachate treatment is to determine the accumulation of SMP in membrane bioreactor ( MBR) and its influence on the slutdge activity and the membrane filterability of the mixed sludge liquor. The results indicated that the concentration of the organic matter held in MBR increased from 226.4 mg/L to 504.0 mg/L with the biodegradability of inlet landfill leachate reducing from 0.60 to 0.28, and the extent of its accumulation in MBR intensified; and the SMP inhibited the sludge dehydrogenase activity and had a negative effect on the membrane filterability of the mixed sludge liquor.
