Abstract

Sewage sludge (SS) is a potential source of bioenergy, yet its management is a global concern. Anaerobic digestion (AD) is applied to effectively valorize SS by reclaiming energy in the form of methane. However, the complex floc structure of SS hinders hydrolysis during AD process, thus resulting in lower process efficiency. To overcome the rate-limiting hydrolysis, various pre-treatment methods have been developed to enhance AD efficiency. This review aims to provide insights into recent advancements in pre-treatment technologies, including mechanical, chemical, thermal, and biological methods. Each technology was critically evaluated and compared, and its relative worth was summarized based on full-scale applicability, along with economic benefits, AD performance improvements, and impact on digested sludge. The paper illuminates the readers about existing research gaps, and the future research needed for successful implementation of these approaches at full scale.

利用厌氧消化进行污水污泥管理和强化能源回收:一种见解。
污水污泥(SS)是一种潜在的生物能源,但其管理却是全球关注的问题。厌氧消化(AD)可通过回收甲烷形式的能源,有效地提高污水污泥的价值。然而,固态污泥复杂的絮状结构阻碍了厌氧消化过程中的水解作用,从而降低了工艺效率。为了克服水解速度限制,人们开发了各种预处理方法来提高厌氧消化(AD)效率。本综述旨在介绍预处理技术的最新进展,包括机械、化学、热和生物方法。对每种技术都进行了严格的评估和比较,并根据其全面适用性、经济效益、厌氧消化(AD)性能改进和对消化污泥的影响总结了其相对价值。该论文向读者阐明了现有的研究差距,以及未来成功全面实施这些方法所需的研究。
