摘要

Abstract

A novel anaerobic reactor

jet biogas inter-loop anaerobic fluidized bed (JBILAFB)

was designed and constructed. The start-up and performance of the reactor was investigated in the process of artificial glucose waste-water treatment. With the wastewater recycle ratio of 2.5:1

the recycled wastewater with biogas could mix sludge and wastewater in the JBILAFB reactor completely. The start-up of the JBILAFB reactor could be completed in less than 70 d through maintenance of hydraulic retention time (HRT) and stepwise increase of feed total organic carbon (TOC) concentration. After the start-up

with the volumetric TOC loadings of 14.3 kg·m

the TOC removal ratio

the effluent pH

and the volatile fatty acids (VFA)/alkalinity of the JBILAFB reactor were more than 80%

close to 7.0 and less than 0.4

respectively. Moreover

was produced at more than 70% of the theoretical value. The reactor exhibited high stability under the condition of high volumetric TOC loading. Sludge granules in the JBI-LAFB reactor were developed during the start-up and their sizes were enlarged with the stepwise increase of volu-metric TOC loadings from 0.8 kg·m

. Granules

an offwhite color and a similar spherical shape

were mainly comprised of global-like bacteria. These had good methanogenic activity and settleability

which were formed probably through adhesion of the bacteria. Some inorganic metal compoun

ds such as Fe

etc

. were advantageous to the formation of the granules.
