摘 要: 在序列间歇式活性污泥法(sequencing batch reactor, SBR)反应器中,先后以葡萄糖和竹品蒸煮废水为碳源,用运行良好的上流式厌氧污泥床(upflow anaerobic sludge blanket, UASB)反应器中厌氧颗粒污泥和城市污水处理厂好氧活性污泥为接种泥,在充氧条件下快速培养好氧颗粒污泥。分析污泥颗粒形态、结构、功能等变化,好氧颗粒污泥的形成是形态变化、成份置换的过程。结果表明:污泥浓度先增加后降低,在运行30 d后逐渐稳定在6 g/L,污泥体积指数(sludge volume index, SVI)值稳定在35 mL/g的水平;粒径集中分布于0.5~1.0 mm,在30~50 d内反应器中颗粒污泥一直占主体成分;处理低浓度和高浓度废水时,对化学需氧量(chemical oxygen demand, COD)的去除率分别达到92%和88%,同时对总磷(total phosphorus, TP)、总氮(total nitrogen, TN)和NH3-N也有良好的去除效率。
关 键 词: 环境工程学;颗粒污泥特性;好氧颗粒污泥;厌氧颗粒污泥;序列间歇式活性污泥法;去除率

Abstract: Anaerobic granular sludge was rapidly cultivated in a sequencing batch reactor (SBR) using glucose and steaming process waste water as carbon source, and anaerobic granular sludge in well-operated upflow anaerobic sludge blanket (UASB) reactor and aerobic activated sludge as inoculation sludge. Changes of appearance, structure and function of aerobic granular sludge were analyzed. Observations on the change of granules’ shape and structure revealed that the granules experienced a shape-keeping and component-replacing process. The sludge concentration increased and later decreased, and after 30 d reached a constant of 6 g/L with its SVI of 35 mL/g. The diameter mainly distributed in 0.5~1.0 mm, granular sludge was dominated in the reactor during 30~50 d of the process. COD removal efficiencies of waster water with high and low concentrations respectively reached 92% and 88%, and favorable removal efficiencies on TP, TN and NH3-N were obtained.
Key words: environmental engineering; granular sludge characteristics; aerobic granular sludge; anaerobic granular sludge; sequencing batch reactor; removal efficiency
