Abstract

The combination of worm bed and sewage treatment system shows a great performance in sludge reduction, and the return of sludge with worm’s predation will also have effects on the sewage treatment system. The system of A2O-MBR, A2O-MBR-blank worm bed and A2O-MBR-worm bed were constructed. After long-term operation, the sludge reduction of A2O-MBR-worm bed coupling system could reach 48.4%. By optimizing the A2O-MBR-worm bed coupling system, the effluent quality of the wastewater treatment system finally can be improved. In addition, the return of sludge with worm’s predation also changed the character of the aerobic tank sludge. Compared with A2O-MBR system and A2O-MBR-blank worm bed, the MLVSS/MLSS of A2O-MBR-worm-bed coupled system was decreased, activated sludge settling characters got weaker and sludge dewatering performance was improved. From the results of TMP and membrane fouling resistance analysis, it was found that the return of sludge with worm’s predation could effectively relieve the process of membrane fouling.
