| 摘 要： | 采用中试规模的反应器对平板膜-污泥浓缩消化(MSTD)工艺的污泥消化机制和膜污染机理进行了研究.结果表明,经过15d的运行,MSTD工艺的污泥浓度(MLSS)从最初的3.6g/L上升到约34.2g/L,MLVSS和MLSS的消解率分别达到52%和47%,实现了同步浓缩和消化.由于溶解氧的变化,MSTD工艺的消化机制分为好氧消化和类似的厌氧消化2个阶段,分别降解二价金属离子和铁离子连接的2类生物聚合物.在MSTD过程中,平板膜的截留和污泥消化导致污泥性质剧烈变化,从而造成膜过滤性能剧烈下降.MLSS、胞外聚合物(EPS)和溶解性微生物产物(SMP)均对膜污染有显著的影响. |

| Abstract: | The mechanisms of sludge digestion and membrane fouling in the process of using flat-sheet membrane for simultaneous thickening and digestion of waste activated sludge(MSTD) were investigated in a pilot-scale reactor.In the MSTD process,the mixed liquor suspended solids(MLSS) reached approximate 34.2g/L from 3.6g/L,and the destruction efficiencies of MLSS and mixed liquor volatile suspended solids(MLVSS) were about 47% and 52%,respectively.The MSTD process successfully realized simultaneous thickening and d... |
