Abstract EN
The microbial characteristics of granular sludge during the rapid start of an enhanced external circulating anaerobic reactor were studied to improve algae-laden water treatment efficiency.
Results showed that algae laden water was effectively removed after about 35 d, and the removal rates of chemical oxygen demand (COD) and algal toxin were around 85 % and 92 %, respectively.
Simultaneously, the gas generation rate was around 380 mL / gCOD.
The microbial community structure in the granular sludge of the reactor was complicated, and dominated by coccus and filamentous bacteria.
Methanosphaera, Methanolinea, Thermogymnomonas, Methanoregula, Methanomethylovorans, and Methanosaeta were the major microorganisms in the granular sludge.
The activities of protease and coenzyme F420 were high in the granular sludge.
The intermittent stirring device and the reverse-flow system were further found to overcome the disadvantage of the floating and crusting of cyanobacteria inside the reactor.
Meanwhile, the effect of mass transfer inside the reactor can be accelerated to help give the reactor a rapid start.
