摘要
以普通絮状活性污泥为种泥,采用人工配水,通过控制运行条件在SBR中成功地培养出了好氧颗粒污泥.研究表明,该好氧颗粒污泥具有良好的同步硝化反硝化和去除COD的性能.好氧颗粒污泥成熟后平均直径为4～5 mm,沉速为72～90m/h,反应器中MLSS为7.8g/L,使反应器对COD和NH3-N的去除率分别达到了95%～98%和75%～90%.
Floccular activated sludge was used as seeding sludge. Aerobic granular sludge was cultivated in sequencing batch reactor (SBR) fed with synthetic wastewater by controlling operational conditions. It is demonstrated that simultaneous nitrification and denitrification, and COD removal can be achieved with high performance. The matured aerobic granular sludge has an average diameter of 4-5 mm and settling rate of 72-90 m/h, with MLSS 7.8 g/L in reactor. The removal rate of COD and NH_3-N comes up to 95%-98% and 75%-90% respectively.
