| Abstract: | An acid hydrolysis- anaerobic-aerobic fixed biofilm system filled with a YDT elasto-steric pocking was used to treat wastewater from coking plant. The results show that when the system was operated with an influent in which the concentrations of COD and NH3-N were 1065 mg/ L and 253 mg/ L respectively, a total hydraulic residence time (HRT) of 33.5 h, and a mixed liquor recirculating ratio of 3.6, then there was an effluent with a COD concentration of about 180 mg/ L and a NH3-N concentration of 5 mg/L, namely that the removals of COD and NH3-N were up to 83% and 98%, respectively. |
