Performance And Removal Characteristics Of Anaerobic Fluidized Bed Reactor (Afbr) Treating Low-Strength Synthetic Wastewater

In this paper, the performance and removal characteristics of an anaerobic fluidized bed reactor (AFBR) treating low-strength synthetic wastewater were studied. It was found that, using granular activated carbon (GAC) as support medium, under the operating condition of temperature (35 +/- 3 degrees C), when the influent COD concentration was 445-537mg/L, hydraulic retention time (HRT) was 6h and GAC bed expansion30%, COD removal efficiency and removal volume loading were 89%,3.98kgCOD/(m(3).d), respectively. The average methane production was 177mL/dand the sludge yield was about 12% COD removed.
