Study on anaerobic fermentation start-up and operation effect of fixed-bed reactor packed with carbon fibre
炭纤维载体固定床厌氧发酵启动运行效果实验

To exploit an efficient and high resistance of shock loading biogas fermentation technology,experiments were conducted to compare the start-up effects between an anaerobic fixed-bed reactor(AFBR) packed with carbon fibre and an up-flow anaerobic sludge bed(UASB) of same specification without any carrier as control.Throughout the experiments the chemical oxygen demand(COD) of feed influent was maintained 5 000 mg/L,the hydraulic retention times(HRT) decreased gradually from 213 hours to 35 hours,and,the ulti...
