抄録

Anaerobic treatability of foul condensate discharged from the evaporation-enrichment process of black liquor from a paper and pulp mill was investigated by using batch and a small scale UASB reactors. The foul condensate used in the experiment was anaerobically biodegraded and the removal rate of CODCr in anaerobic treatment was expressed as the first-order reaction with respect to the biodegradable CODCr, and the reaction rate constant was 3-5 X 10-5l·mg-1·h-1. The CODCr removal efficiency in an UASB reactor was as high as 70% when the volumetric CODCr loading was lower than 10kg·m3·d-1. Methane productivity of the condensate was 0.16-0.24 Nm3·kg-1-CODCr.
