Biochemical methane potential (BMP) tests have been conducted to optimize the conditions of biogas and methane production and applied to a semi-continuous operation system.The results showed that Under the optimum conditions, the methane production increased by 46.6% in the batch tests and 120% in the semicontinuous operation system compared to the control reactor. The improved methane production originated from the synergetic effect of combining Fe0 and Mg(OH)2. The crucial role of the Mg(OH)2 coating layer was associated with the controlled reactivity release of Fe0, which was indicated by the slow release of Fe2+ and Fe3+ in the bioreactors. Furthermore, the addition of coated/Fe0 stimulated bacterial growth increased methane content and maintained the pH within the optimum range in the bioreactors. The dosing time of coated/Fe0 was investigated during the four stages of the anaerobic digestion process, and the best dosing time was found in the methanogenic stage (on Day 4). Overall, based on the experimental and predicted methane production, the coated/Fe0 has great potential for the practical applications of anaerobic digestion.The main Achievements have been published in Renewable and Sustainable Energy Reviews with an impact factor of 16.799 under the title A novel method to improve methane generation from waste sludge using iron nanoparticles coated with magnesium hydroxide. Currently the second paper currently in progress.

已经进行了生化甲烷电位（BMP）测试，以优化沼气和甲烷生产的条件并应用于半连续的操作系统。结果表明，与对照反应器相比，在最佳条件下，在批处理测试中，甲烷的产生在批处理测试中增加了46.6％，在半连续操作系统中增加了120％。改善的甲烷产生起源于结合Fe0和Mg（OH）2的协同作用。 Mg（OH）2涂层的关键作用与Fe0的受控反应性释放有关，这是由生物反应器中Fe2+和Fe3+缓慢释放所表明的。此外，添加涂层/Fe0刺激细菌生长增加了甲烷含量，并将pH值保持在生物反应器的最佳范围内。在厌氧消化过程的四个阶段研究了涂层/FE0的给药时间，并且在甲烷植物阶段（第4天）发现了最佳的给药时间。总体而言，根据实验性和预测的甲烷产生，涂层/FE0具有巨大的潜力，可以实现厌氧消化的实际应用。主要成就已发表在可再生和可持续的能源评论中，其影响因子为16.799，其影响为16.799，标题是一种新颖的方法，一种新的方法，可以通过使用Magnapartice copatiuim y Magnateciuim Hydrox的含铁浆料来改善甲烷产生的甲烷产生，从而改善甲烷的产生。目前正在进行的第二篇论文。
