%X Seeded with municipal anaerobic digested sludge, one (R1) was added with a bio-flocculant MBF21, the other (R2) was the control without any flocculant addition during their start-up of UASB treating low concentration wastewater. And the impact and mechanism of bio-flocculant MBF21 on anaerobic granulation were investigated. As the experiments ended, the granular sludge size from R1 was 0.3 mm larger than that from R2; and the special methanogenic activity (SMA) of granular sludge from R1 was 31% higher than that from R2. The properties of the anaerobic sludge during different period in the experiments were measured with SEM and fluorescence microscope photos. The results confirmed that it was the absorptive bridge between bio-flocculant and anaerobic microbes that enhancing the anaerobic granulation.
