摘要：

为研究弹性填料对厌氧折流板反应器（ABR）去除重金属及颗粒污泥的影响，采用有弹性填料ABR和无弹性填料ABR进行对比。结果表明，弹性填料有利于提高ABR去除生活污水中的多数重金属；两组ABR各隔室中的厌氧颗粒污泥粒径沿着水流方向逐渐减小，但多介于0.75～1.25mm之间，有弹性填料ABR各隔室中的厌氧颗粒污泥粒径略小于无弹性填料ABR；通过扫描电镜发现，两组ABR第1隔室中的厌氧颗粒污泥表面含有大量的丝状菌，第2～4隔室中的厌氧颗粒污泥表面的丝状菌显著减少，但胞外聚合物的含量有所增加；与无弹性填料ABR相比，有弹性填料ABR各隔室中的厌氧颗粒污泥表面的丝状菌有所减少；通过能谱仪元素分析发现，两组ABR各隔室中的厌氧颗粒污泥表面最主要的元素为C、O和N，此外，还包括Na、Al、P、Ca、Fe、As、Hg和Pb等；与无弹性填料ABR相比，有弹性填料ABR各隔室中的厌氧颗粒污泥表面的重金属元素含量有所减少。

Abstract:

Aiming to explore the effect of elastic filler on the removal of heavy metals and granular sludge by ABR (anaerobic baffled reactor), ABR with and without elastic filler were compared. The result showed that elastic filler was beneficial to the removal of most heavy metals from domestic sewage by ABR. The particle size of anaerobic granular sludge in two groups of ABR compartments decreased gradually along the flow direction, but most of them were between 0.75mm and 1.25mm, and the particle size of anaerobic granular sludge in the compartmentsof ABR with elastic filler was slightly smaller than that of ABR without elastic filler. Found by SEM, a large number of filamentous bacteria were found on the surface of anaerobic granular sludge in the first compartment of ABR in the two groups, and the filamentous bacteria on the surface of anaerobic granular sludge in compartments 2,3 and 4 reduced significantly, but the content of extracellular polymer increased. Compared with the ABR without elastic filler, the filamentous bacteria on the surface of anaerobic granular sludge in compartments of ABR with elastic filler were reduced. Found by EPS, the main elements on the surface of anaerobic granular sludge in two groups of ABR compartments were C, O and N. In addition, Na, Al, P, Ca, Fe, As, Hg, and Pb were also included. Compared with the ABR without elastic filler, the content of heavy metals on the surface of anaerobic granular sludge in compartments of ABR with elastic filler was reduced.
