Abstract:
The application of a technology that combined anaerobic membrane bioreactor (AnMBR) and constant waterlevel sequencing batch reactor (CWSBR) in the treatment of fishing industry wastewater was analyzed. After 140 d continuous experiment, the average removal rate of COD from the AnMBR system was 91%, in which the microbial removal of COD was 84%. The membrane showed 42% interception efficiency on COD, and the effluent COD remained between 140 mg/L to 180 mg/L. The CWSBR system demonstrated great efficiency in the removal of organics and nitrogen from the AnMBR effluent. The effluent COD remained stably at 30 mg/L. Under low C/N ratio conditions, the effluent TN was maintained between 10 mg/L to 20 mg/L. When the AnMBR system had a constant membrane flux of 10 L/(m2·h), the membrane cleaning was performed in 20 d to 30 d.
