摘要: 以葡萄糖为基质,研究浮动盖式ASBR中颗粒污泥的形成。实验结果表明,污泥在120 d时完全颗粒化,颗粒污泥具有良好的沉降性能(25 m/h)及良好的产甲烷活性,甲酸、乙酸、丙酸及丁酸最大代谢活性分别达到0.216、0.825、0.237和0.796 g COD/(g VSS·d)。电镜扫描(SEM)发现,整个污泥结构均一,均由丝状菌构成。

Abstract: The formation of granular sludge in a bench-scale anaerobic sequencing batch reactor (ASBR) fed with glucose as substrate was investigated. The granulation of sludge was completed in about 120 days, which was much shorter than that reported before. The granular sludge had good settling ability (25 m/h) and specific methanogenic activity. The maximum of metabolic activity for formic acid, acetate, propionate and butyrate were 0.22, 0.83, 0.24 and 0.70 g COD/(g VSS·d), respectively. Scanning electron microscope images showed that the compact granules composed predominantly of the filamentous bacteria like Methanosaeta even under the condition of high acetate concentration
