Polyvinyl alcohol (PVA)-containing desizing wastewater discharged from final textile wastewater has a great impact on the environment. In the paper, an improved lab-scale hybrid anaerobic baffled reactor (HABR) was developed to treat desizing wastewater. Under optimum condition (alkalinity of influent 500 mg/L, effluent recycle ratio of 94 times influent rate and hydraulic retention time of 5 d), the system demonstrated a good performance of COD and PVA removal efficiencies (around 42.0% and 18.0% respectively) and the average concentration of alkalinity in the effluent was around 700 mg/L and pH value was above 6.8. Microbial selection and zoning are encouraged inside the HABR. The improved lab-scale HABR proved to be a suitable technology for desizing wastewater treatment. (C) 2011 Elsevier B.V.
