Paper Title:
The Coupling Bioreactor for Domestic Wastewater Reclamation and Sludge Reduction
  Abstract

Based on the theory of flow separate and multi-phase reaction principle, the coupling bioreactor for domestic wastewater reclamation and the sludge reduction was developed in this paper. The results showed that the coupling bioreactor kept stable COD removal efficiency above 85% with the COD loading rate increased from 0.49kgCOD/(m3∙d) to 1.93kgCOD/(m3∙d). Moreover, the excellent effluent quality could be obtained under the condition of Micro-aeration+ Anoxic + Aeration, and the total nitrogen(TN) removal of 86.7% was achieved at HRT of 8h and 43% volume ratio of anoxic zone, meanwhile the effluent TN concentration was lower than 15mg/L and a lower sludge production rate was obtained with mean value of 0.068MLSS/kgCOD.
