摘　　要：采用厌氧、好氧交替运行的小试SBR反应器实现了在秋、冬季无保温措施下好氧颗粒污泥的培养及对生活污水中污染物的去除。研究发现在秋、冬季温度由18℃逐渐降至10℃并长期维持在较低温度的条件下,SBR反应器中形成了具有良好物化特性的颗粒污泥,稳定期污泥的平均粒径为300μm,反应器中有较高的生物量(MLSS为6 000 mg/L),污泥沉降性能较好,SVI为50~60 m L/g。对COD、PO_4^(3-)-P、NH_4^+-N均具有较好的去除效果,平均去除率分别达到85.8%、98.3%、99.2%。通过在反应周期结束增设2 h缺氧搅拌,实现了对TN的进一步去除,去除率达95.2%。The aerobic granular sludge was cultivated in a SBR reactor operated in anaerobic/aero-bic alternating mode, and was applied to treat municipal domestic sewage in cold region under low tem- perature. The aerobic granular sludge was cultivated successfully as the average particle size of the granu- lar sludge was 300 i.Lm, the MLSS was 6 000 mg/L, and the sludge showed good settleability as the SVI kept at 50 to 60 mL/g when the temperature reduced from 18 ~C to 10 ~C and kept at low value for a long time. The aerobic granular sludge had excellent removal effect on COD, PO43- - P and NH4＋ - N, and the average removal rates were 85.8%, 98.3% and 99.2% respectively. Additionally, TN removal rate of 95.2% was achieved by adding 2-hour anoxic mixing time.
