Abstract
An anaerobic moving bed biofilm reactor filled with small and low density polyethylene support as biofilm carrier was operated to treat wine distillery wastewater for nearly 8 months. The support packed in the reactor is Bioflow 30 with density 0.92g/cm3 and specific surface area of 320m2/m3. The reactor achieved soluble COD removal efficiency of 86.1% at organic loading rate(OLR) between 16.88 and 18.43g COD/l/ d and an hydraulic retention time(HRT) of 2.49days. The experimental results show that the reactor is an interesting choice for anaerobic digestion of wine distillery wastewater. The experiment provides a good base for choosing packing in implementation of the reactor.
