Abstract：According to the characteristics of catalyzed iron technology and hydrolysis & acidogenesis process, the coupling system was established to improve the biodegradability of the wastewater. The advection coupled reactor was designed and applied to the actual renovation project of wastewater treatment plant in chemical industry park. After implementation of the actual renovation project, the influent and effluent water qualities were detected and the biodegradability of the wastewater was analyzed. The treatment efficiency of hydrolysis & acidogenesis/catalyzed iron-CAST system was compared with that of the pure CAST system. The results indicate that ρ(BOD5)/ρ(COD) is improved to above 0.35 with the pretreatment of hydrolysis & acidogenesis/catalyzed iron coupling technology. The average effluent COD, ammonia nitrogen and total phosphorus of hydrolysis & acidogenesis/catalyzed iron-CAST system are 91，17.2 and 2.39 mg·L-1 respectively, and the corresponding average removal rates increase respectively from 69%, 0 and 46% to 75%, 46% and 57%.
