Abstract

In this study, the influence of F/M (total organic carbon (TOC)/mixed liquor suspended solids (MLSS)/day) ratio in the anaerobic batch treatment method was performed on the distillation effluent of barley shochu. The operation was to add 0.7 L seed sludge, supply 0.2 L of waste liquid every day and react until it reached 1.5 L. The Four loading types can be changed by changing the dilution rate. Through this operation, MLSS was changed in the range of 10 to 24 g/L, TOC was changed in the range of 1000 to 5000 mg/L, and the F/M ratio was changed in the range of 0.09 to 0.50/day. Appropriate treatments can be maintained to a F/M ratio of 0.36/day. Furthermore, a methane production rate is 2.1 L/day with a methane content of 60% and a methane production yield of 0.9 L/g with TOC removal rates in the range of 70-90%.
