【摘要】:本文在厭氧反應器探究了超聲破解對生物酶強化污泥厭氧消化的影響,實驗結果表明超聲能促進生物酶強化污泥厭氧發(fā)酵生產揮發(fā)性脂肪酸,且最佳的超聲能量密度為0.9kW/L,相應的VFA的產量為2596mg/L是空白組的1.5倍。超聲能量密度對VFA的組分影響不明顯。超聲能夠促進污泥中溶解性化學需氧量,溶解性蛋白質和多糖的增加,為后續(xù)產酸菌提供了發(fā)酵基質。
[Abstract]:The effect of ultrasonic decomposition on anaerobic digestion of bio-enzymatic sludge was investigated in an anaerobic reactor. The results showed that ultrasound could promote the production of volatile fatty acids by enzymatic anaerobic fermentation of sludge. The optimal ultrasonic energy density was 0.9 kW/L, and the corresponding VFA yield was 1.5 times higher than that of the blank group. Ultrasound can promote the increase of dissolved COD, soluble protein and polysaccharide in sludge, and provide a substrate for subsequent acid-producing bacteria.
