【摘要】：研究了AMBR-MABR處理模擬畜禽養(yǎng)殖廢水的啟動過程和成熟污泥的特征。通過在AMBR厭氧格室和MABR格室分別接種ABR-MABR對應格室中的污泥,然后固定停留時間、逐步升高進水負荷進行AMBR-MABR的啟動。83 d后,AMBR-MABR的有機負荷(OLR)(以COD計)達到7.5 kg·(m3·d)-1,COD、NH+4-N和總氮去除率分別可達83.96%、37.56%和38.29%,反應器啟動成功。啟動成功后,AMBR-MABR污泥的濃度在17.5~30.0 g·L-1之間;厭氧格室污泥的粒徑為0.25~0.74 mm,曝氣格室污泥的粒徑均為0.18 mm。AMBR-MABR中各格室的污泥表面凹凸不平,疏松多孔,主要由桿狀菌、球狀菌、念珠狀菌及胞外聚合物(EPS)等組成,EPS主要為多糖、蛋白質和溶解性微生物代謝產物,富里酸和腐殖酸的含量較少。反應器中微生物種類豐富,微生物群落可以分為3類:第1類為Ⅰ、Ⅵ格室;第2類為Ⅱ、Ⅲ格室;第3類為Ⅳ、Ⅴ格室,這與PCA分析的結果一致。
[Abstract]:The start-up process and mature sludge characteristics of simulated livestock and poultry wastewater treated with AMBR-MABR were studied. Sludge was inoculated in the AMBR anaerobic compartment and the MABR compartment, respectively, and the residence time was fixed. The organic load of AMBR-MABR (measured by COD) reached 7.5 kg / m ~ 3 / d ~ (-1) COD NH _ 4-N and removal efficiency of total nitrogen reached 83.96% ~ 37.56% and 38.29% respectively. The reactor was successfully started. After successful start-up, the concentration of AMBR-MABR sludge was between 17.5 ~ 30.0 g 路L ~ (-1), the diameter of anaerobic cell sludge was 0.25 ~ 0.74 mm, the diameter of aeration cell sludge was 0.18 mm.AMBR-MABR, the sludge surface of each cell was rough and porous, which was mainly composed of rod bacteria and globular bacteria. The main components of EPS are polysaccharide, protein and soluble microbial metabolites, and the contents of fulvic acid and humic acid are less. The microbial community can be divided into three types: the first type is 鈪，
