✦ Synopsis

Bench-scale air lift-internal-loop reactor (AILR) results indicate that AILR was superior to the activated sludge process for the treatment of cokechemical wastewater. AILR had a high COD removed rate of 7 kg/day m3, while COD loading rate was 13 kg/day m3. AILR was adaptable for high loading of phenol and cyanide and had high removal percentage for them. The COD removal rate was 54.5-76% in AILR, while the phenol removal percentage was 99.5-99.8% and cyanides 99.2-95%. The air consumption in AILR was about 21 m"/(kg COD removed), which was l/3-1/4 of that in an activated sludge process.
