This review focuses on current status of pulsed electric field (PEF) technology and its implementation in biogas production. First, basic principles of PEF and a schematic overview of typical PEF processing system were provided. Thereafter, lab- and pilot-scale PEF pretreatments of sludge with subsequent anaerobic digestion (AD) were provided. Furthermore, PEF technology, as an emerging technology for the lignocellulose (LC) pretreatment in biogas production which is still predominantly used at lab-scale, was outlined. Eventually, conclusion together with future perspectives and challenges were outlined.

脉冲电场：沼气生产中一种新兴的预处理技术

本文着重介绍脉冲电场（PEF）技术的现状及其在沼气生产中的实施。首先，提供了PEF的基本原理和典型PEF处理系统的示意图。此后，提供了实验室规模和中试规模的污泥PEF预处理以及随后的厌氧消化（AD）。此外，概述了PEF技术，它是一种在沼气生产中用于木质纤维素（LC）预处理的新兴技术，目前仍主要在实验室规模使用。最后，总结了结论以及未来的观点和挑战。
