纳米 Fe 强化污泥厌氧消化产甲烷的研究

摘要

介绍了利用纳米Fe强化污泥高效产甲烷的方法。实验结果表明，纳米Fe最佳投放量为6 g／L ，相应的甲烷产量（以VSS计）为198 mL／g。机理研究表明，纳米Fe能够促进污泥水解、酸化，进而促进甲烷的积累。%In this study ,a new method based on nano Fe to enhance methane production from sludge anaerobic digestion is reported .Experimental results show that the optimum dosage of nano Fe is 6 g/L and the corresponding methane production is 198 mL/g VSS .Mechanism study shows Nano Fe can enhance sludge hydrolysis and acidification ,thereby causing the enhancement of methane accumulation .
