Anaerobic hydrolysis and acidogenesis of milk wastewater

Experiments were conducted for anaerobic hydrolysis of milk wastewater in CSTR, and experimental results indicated that anaerobic hydrolysis fermentation of milk wastewater was a butyric-type fermentation; Hydrolysis to amino acid was a rate-limiting step for protein anaerobic degradation; Accumulate of C18:1 was the main reason for efficiency drop of protein anaerobic hydrolysis. The CSTR reactor was not a biohydrogen production reactor suitable for anaerobic treatment of milk wastewater.
