摘要：

Synthetic wastewater consisting aliphatic acids contained in distillery wastewater from barley-shochu making was treated anaerobically. It was suggested that propionic acid was produced from lactic acid and citric acid via succinic acid. Since it appears to be difficult to treat anaerobically wastewater in which propionic acid is accumulated, we attempted to repress the production of propionic acid during acidification. The amount of propionic acid produced increased with an increase in the hydraulic retention time (HRT) at pH 7. Although the treatment was examined using different pHs at a shorter HRT of 10 h, it was difficult to repress the production of propionic acid.
