摘　　要：试验对传统两段式生物反应器(TSBR)进行了改进,二段采用生物膜膜生物反应器(BMBR);在一段HRT=SRT=2.82～4.23h,二段HRT=6.44～9.66h、SRT→∞,每日空曝气8h的运行条件下,对该工艺进行了试验研究。结果表明,系统稳定后,出水水质稳定,CODCr、NH+4N和TP的去除效率分别为95%、80%和60%以上,膜污染得到了有效控制。Combining two stage bioreactor(TSBR) with biofilm membrane bioreactor(BMBR) was researched under operating conditions that HRT=SRT=1.94 h in the first stage, HRT=4.4 h,SRT →∞ in the second stage and aeration eight hours in the reactor without any influent and effluent every day.The results show:After the system stabilization, the water quality of effluent was stable,satisfactory COD, NH+_4-N and total P removal efficiencies were achieved,averaging over 95%,80% and 60%,respectively. The fouling of membrane was effectively controlled.
