摘要：

A two-stage pilot reactor has been tested for the anaerobic digestion of distillery wastewater with a COD of-10,000 mg/1. In the first stage (residence time 16-72 hours), carbohydrates are fermented to low molecular weight metabolites. The second stage is an upflow reactor (residence time 14 hours) in which these metabolites are converted to biogas. Overall COD elimination is 84% (BOD, 92%) with biogas production 5-7 times the active volume of the upflow reactor per day. The process withstands temporary stress conditions fairly well. The results indicate that anaerobic treatment in the upflow reactor qualifies as an efficient and low cost method for distillery wastewater treatment. © 1979 Kluwer Academic Publishers.
