摘要：

自制了一套新型一体式厌氧/好氧/动态膜生物反应器(A/O/DMBR),并将其应用于高浓度氨氮化粪池废水的处理。结果表明,A/O/DMBR达到了良好的有机物和氨氮去除效果,平均去除率分别为81.5%和87.0%。同时还表现出较强的脱氮能力和较好的稳定性,好氧单元和缺氧单元污泥的比硝化速率和比反硝化速率分别达到2.79、1.33 mg/(g.h)。

Abstract:

An integrated anaerobic/oxidic/dynamic membrane bioreactor (A/O/DMBR) has been developed and applied to the treatment of wastewater from septic tanks. A/O/DMBR presents good removing effects on COD and NH₃-N,obtaining average COD removal rate of 81.5% and NH₃-N removal rate of 87.0%,respectively. Moreover,A/O/DMBR presents strong capability of TN removal and stability,since the sludge in the aerobic tank has good nitrification capacity of 2.79 mg/ (g.h) and that in the anaerobic tank has good denitrification capacity of 1.33 mg/ (g.h)， respectively.

Key words: membrane bioreactor, dynamic membrane, wastewater from septic tank, high ammonia-nitrogen wastewater
