capacity limits.

    MIC和UASB反应器处理水葫芦汁潜力得到了研究；

2. MIC exhibited a higher energy conversion rate and stronger performance than
UASB.

   与UASB反应器相比，MIC反应器显示了更高的能源回收率和处理能力；

3.The methane production rate and removal OLR showed a linear relationship.

    甲烷产率和有机负荷呈现出了较好的线性关系；

   MIC and UASB reactors had similar predominant methanogens: Methanosaeta.

4. UASB反应器和MIC反应器处理水葫芦汁反应得出，产甲烷优势菌群均为鬃毛甲烷菌属（Methanosaeta）；

Acetoclastic methanogenesis was the dominant metabolic pathway in WHJ
treatment

    UASB反应器和MIC反应器处理水葫芦汁中主要为乙酸型产甲烷代谢路径；

Novel start-up process for the efficient degradation of high COD wastewater with up-flow anaerobic sludge blanket technology and a modified internal circulation reactor，Bioresource Technology 308 (2020) 123300 

Highlights

• A novel start-up process (NSP) was developed and verified in UASB and MIC reactors.

• NSP time of MIC reactors (46 days) was less than that of UASB reactors (52 days).

• NSP (23,500 mg/L) had higher influent COD than traditional startups (250–6500 mg/L).

• The biogas production rate of MIC was three times higher than that of the UASB.

• Methane was dominately generated through acetoclastic pathway by Methanosaeta.

Evaluation of methane emission flux from a typical biogas fermentation ecosystem in China，Journal of Cleaner Production，Volume 257, 1 June 2020, 120441

Highlights

• CH4 emission fluxes from a typical hydraulic biogas digester in China were studied.

• The diurnal and monthly variations from January to July were characterized.

• Different environmental factors had various influences on the CH4 emission fluxes.

• Leak of CH4 emission has non-negligible effect on the methane conversion factor.
