Start-up of anaerobic baffled reactor (ABR) and the feature of granular sludge forming
|
Abstract:
The paper reports the start-up of ABR and the feature of granular sludge forming. The results reveal that low organic loading rate is the key to start-up of reactor. The significant factor was the suitable anaerobic micro-organisms, hydraulic loading rate and buffer. ABR was successfully started-up and formed granular sludge in 60 d operation at an organic loading rate of 0.85-1.50 kg(COD)/(m3·d),hydraulic loading rate of 0.198 m2/(m3·h),the buffer of effluent of 500 mg CaCO3/L.Because the condition of each compartment was various, the feature of sludge was different.But the different granular sludge is composed of the filiform bacterium, which adsorbed inertia matter, and there were plentiful holes in granular sludge, which supply the condition for the removing and degrading of matter.
