摘要
采用连续流一体化氧化沟处理校园生活污水,探讨其培养好氧颗粒污泥的可行性。结果表明,反应器经过19d的运行,即可培养出粒径为200~400μm、外形规则、结构密实的好氧颗粒污泥;好氧颗粒污泥的存在有利于反应器对COD、NH_4^+-N、TN、TP的去除;较高的污泥有机负荷和溶解氧浓度有利于好氧颗粒污泥的形成与稳定。
The feasibility of cultivation of aerobic granular sludge in a continuous flow integrated oxidation ditch fed with schoolyard domestic wastewater was investigated. The results showed that, aerobic granular sludge with regular shape,compact structure and diameter of 200-400 μm was cultivated after operating 19 d. Existence of aerobic granular sludge enhanced the removal efficiencies of COD, NH4-N, TN and TP. High or ganic sludge loading and dissolved oxygen concentration were benefit for the formation and stability of aerobic granular sludge.
