| 摘 要： | 以猪粪为发酵原料，研究消毒剂福尔马林对沼气发酵的影响，以期为养殖场粪污产沼气发酵处理提供技术指导。研究结果表明，消毒剂福尔马林对沼气发酵有抑制作用，使沼气发酵体系的挥发性总脂肪酸含量和脂肪酶活性增加，α-淀粉酶和纤维素酶的活性降低，产气量下降。随着添加量增加，这种变化趋势增强，当添加量达到0.05%时，挥发性总脂肪酸含量增加18.78%，脂肪酶活性提高135.13%，α-淀粉酶和纤维素酶的活性分别下降78.57%和83.65%。研究结果从机理上解释了养殖场粪污进行沼气发酵处理时，出现产气量下降甚至不产气的原因。可为养殖场粪污沼气发酵处理提供一定的技术指导，以保证沼气发酵的正常进行。

| Abstract: | Using pig dung as material, the effect of formalin on biogas fermentation were studied in this paper. The experimental results showed that the formalin disinfectant had restraint effect on biogas fermentation. After adding formalin, the content of total volatile acid and lipase activity increased, but amylase activity, cellulase activity and gas yield decreased. With increasing of dosage, the change became strengthening. When the addition of formalin reached to 0.05%, the content of total volatile acid increased by 18.78%, lipase activity increased by 135.13%, and amylase activity and lipase activity decreased by 78.57% and 83.65%, respectively. The results of research explained why gas yield decreased when the faeces of livestock farms was handled with for biogas fermentation. The results can provide a certain theoretic reference for biogas fermentation of faece from livestock farms. |
