  • 摘要: 研究了AMBR-MABR处理模拟畜禽养殖废水的启动过程和成熟污泥的特征。通过在AMBR厌氧格室和MABR格室分别接种ABR-MABR对应格室中的污泥，然后固定停留时间、逐步升高进水负荷进行AMBR-MABR的启动。83 d后，AMBR-MABR的有机负荷（OLR）（以COD计）达到7.5 kg·（m3·d）-1，COD、NH4+-N和总氮去除率分别可达83.96%、37.56%和38.29%，反应器启动成功。启动成功后，AMBR-MABR污泥的浓度在17.5~30.0 g·L-1之间；厌氧格室污泥的粒径为0.25~0.74 mm，曝气格室污泥的粒径均为0.18 mm。AMBR-MABR中各格室的污泥表面凹凸不平，疏松多孔，主要由杆状菌、球状菌、念珠状菌及胞外聚合物（EPS）等组成，EPS主要为多糖、蛋白质和溶解性微生物代谢产物，富里酸和腐殖酸的含量较少。反应器中微生物种类丰富，微生物群落可以分为3类：第1类为Ⅰ、Ⅵ格室；第2类为Ⅱ、Ⅲ格室；第3类为Ⅳ、Ⅴ格室，这与PCA分析的结果一致。
    Abstract: The start-up and characteristics of mature sludge were studied for an anaerobic migrating blanket reactor-membrane aeration biofilm reactor (AMBR-MABR) to treat synthetic livestock wastewater. The corresponding sludge of ABR-MABR were employed as the seed for AMBR and MABR compartments, respectively, and the duration of start-up time lasted 83 d until the organic loading rate (OLR)(caculated by COD) reached 7.5 kg·(m3·d)-1 at a HRT and a step-increased influent load. After start-up, the average removal rates of COD, NH4+-N and TN for AMBR-MABR could approach about 83.96%, 37.56% and 38.29%. The MLSS values of mature sludge in AMBR-MABR compartments ranged from 17.5 to 30.0 g·L-1. Their median diameters were from 0.25 to 0.74 mm in anaerobic compartments and 0.18 mm in aeration ones. The surface of mature sludge was uneven and porous and it was mainly composed of bacillus, coccus, beads and extracellular polymeric substances (EPS). Main EPS fractions were determined as protein and soluble microbial byproduct-like materials, while the contents of fluvic acid and humic acid-like materials were low. Based on the cluster analysis, the microbial community in AMBR-MABR could be divided into 3 clusters:Ⅰ and Ⅵ, Ⅱ and Ⅲ, Ⅳ and Ⅴ, which was consistent with the results of principal component analysis(PCA).
