牛奶废水厌氧水解酸化试验研究

Anaerobic hydrolysis and acidogenesis of milk wastewater

利用CSTR反应器进行了牛奶废水厌氧酸化实验研究.结果表明,牛奶废水的厌氧水解酸化过程表现为丁酸型发酵;蛋白质水解为氨基酸是蛋白质类物质厌氧处理的限速步骤;长链脂肪酸C18:1(含一个双键的不饱和油酸)的积累是造成蛋白质厌氧水解酸化效率降底的主要原因之一;在牛奶废水的厌氧处理过程中用CSTR反应器作为生物产氢反应器是不适宜的.

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.
