The objective of this study is to investigate the energy consumption of pre-treating excess sewage sludge with microwave irradiation using several parameters, including temperature rise, degree of cell destruction, SCOD/TCOD ratio (solids solubilization), and biogas production to evaluate the energy efficiency. It was found that water content was the most important factor that influenced the energy efficiency of raising the temperature and promoting the solubilization of solid materials. Increasing specific energy (E(s)) accelerated the biogas production, but there was a limit to this process. For quantitative comparison to the energy efficiency of different pre-treatment steps, an empirical method was also proposed based on the experimental data.
本研究旨在通过微波辐照预处理剩余污泥的几个参数（升温、细胞破坏程度、SCOD/TCOD 比（固体溶解）和沼气产量）来研究其能量消耗，以评估能量效率。结果发现，水分含量是影响升温效率和促进固体材料溶解的最重要因素。增加比能（E(s)）会加速沼气的产生，但这种过程是有限的。为了对不同预处理步骤的能量效率进行定量比较，还根据实验数据提出了一种经验方法。
