摘要:

膜生物反应器(MBR)作为一种高效的污水处理及回用工艺,近年来备受关注,然而MBR的膜污染问题严重制约了该工艺进一步快速的商业化推广。本文综述了金属离子对MBR污泥混合液可滤性的作用,并探讨了混合液中胞外聚合物(EPS)和溶解性微生物代谢产物(SMP)对膜污染影响。为说明高价金属离子对混合液可滤性的调控作用,文中通过DLVODCB及箱蛋理论深入探讨了金属离子对生物絮凝影响的机理。最后,对该领域未来的研究方向进行了论述。

Abstract:

Membrane bioreactorMBRhas received great attention in wastewater treatment and reclamation. Membrane fouling is a major obstacle that hinders faster commercialization of MBR. This review summarizes the influence of metal ions on the filterability of mixed sludge in MBR and extracellular polymeric substancesEPSand soluble microbial productsSMPon membrane fouling. In order to provide more detailed information between metal ions and the filterability of mixed sludge in MBRthe mechanism of metal ions in bio-flocculation is described according to DLVO theorythe alginate theory and the divalent cation bridgingDCBtheory. Prospects for the future trends in filterability study of mixed liquor are discussed.
