摘要
通过对比试验对冬季低温（8～12℃）奈件下A^2／O和A^2/O挂膜工艺的启动进行了研究。启动阶段COD／NH3-N较低（33～7．2）。采用接种污泥间歇培养法驯化污泥7d，然后连续进水运行20d后，A^2／O和A2／O挂膜反应器对COD及NH3-N去除率分别为60％和70％以上，表明反应器启动过程完成。
This tests by comparing the low temperature in winter （8-12 ℃） under the A2/O and A2/O process linked to membrane was studied. COD/NH3-N lower start-up phase （3.3-7.2）. Batch culture inoculated with acclimated sludge 7 d, then run straight water after 20d, A2/O and A2/O hanging membrane reactor, COD and NH3-N removal rates were respectively above 600 and 70%, indicating that reactor startup process is complete.
