Decentralization Treatment of Papermaking Wastewater by a Sequential Biological Fluidized Bed

摘要：

In the present work, the papermaking wastewater was treated by combing fluidized bed biological reactor (FBBR) with sequential batch reactor technology (SBR).Particular attention was paid to the acclimation process, then confirmed the optimal operation, which consisted of 6 h cycle including an inflow process, 6 h aeration process, 2 h settling process, 2 h drainage process and 6h idle process. Under these conditions, CODCr removal efficiency reached 94.4%, NH3-N concentration were reduced to 5 mg/L from 30 mg/L,maximal removal efficiencies of color and SS were obtained as 91.7% and 86.0%, respectively. Most of toxic organic substances were eliminated at shorter operational time. The study suggests that the combined sequential batch reactor technology with fluidized bed biological reactor is a potential alternative for papermaking wastewater treatment.
