- 摘要:在间歇培育前提下,研究了还原型辅酶Ⅱ(NADPH)、乙酰辅酶A(Acetyl Co A)和对氨基苯甲酸(PABA)3种添加剂对污泥厌氧消化机能的影响.成果注解,3种微生物活性增进剂均能增进污泥厌氧消化产气.此中,NADPH的增进结果最为显著,消化第35 d,产甲烷量比对比组高15.90%.在污泥含固率为3%、未调初始 pH(pH=6.7)和温度35 ℃的厌氧消化前提下, NADPH的最好添加量为50 mg·L-1,消化第36 d,污泥积累产甲烷量127.13 mL·g-1 VSS.在含固率3%、初始pH=8.5、温度55 ℃和NADPH添加量为50 mg·L-1 的工艺前提下,污泥厌氧产气结果最好,消化第30 d时积累产甲烷量达158.02 mL·g-1 VSS.

- NADPH Abstract:This study investigated the effects of different additives(NADPH, Acetyl Co A, PABA)on biogas production in anaerobic digestion system. All the three microbial activity accelerants favored the anaerobic digestion, and NADPH achieved the most effective promotion for methane production. The reactor with NADPH had higher methane production, up to 15.90%, than the control group.Under the anaerobic conditions of 3%solid content, initial pH 6.7 for raw sludge and 35 ℃ digestion temperature, the optimal dosage of NADPH is 50 mg·L-1, and the accumulative methane production achieved 127.13 mL·g-1 VSS after digestion for 36 days. The maximal accumulative methane production achieved 158.02 mL·g-1 VSS under the following conditions: 3% solid content, initial sludge pH 8.5, temperature 55 ℃ and NADPH dosage 50 mg·L-1.
