摘要：
Performance of an attached growth methane phase was compared to that of a completely mixed methane phase in a two-phase anaerobic process. An anaerobic rotating biological contactor (AnRBC) and a completely mixed stirred tank reactor (CSTR) were used to study the attached growth and suspended growth phase systems, respectively. In the methane phase, the hydraulic retention time (HRT) was varied from 10 to 72 hours and the pH was maintained either at 6. 0 or at 7. 5. The attached growth methane system was observed to be more efficient than the suspended growth methane process in methane production per gram of total organic carbon (TOC) removed.
