Abstract:
This manuscript presents a scientometric review of recent advances in microwave pretreatment processes for sewage sludge, systematically identifying existing gaps and prospects. For this purpose, 1763 papers on the application of microwave technology to sludge pretreatment were retrieved from the Web of Science (WoS) using relevant keywords. These publications were then analyzed using diverse scientometric indices. The results show that research in this field encompasses applications based on the non-thermal effects of microwaves, enhanced effectiveness of anaerobic digestion (AD), and the energy balance of this pretreatment system. Overcoming existing technical challenges, such as the cleavage of extracellular polymers, reducing microwave energy consumption, understanding the non-thermal effects of microwaves, promoting AD of sludge in combination with other chemical and physical methods, and expanding the application of the technology, are the main scientific focuses. Additionally, this paper thoroughly examines both the constraints and potential of microwave pretreatment technology for wastewater treatment.
摘要:
该手稿对污水污泥的微波预处理工艺的最新进展进行了科学综述,系统地确定现有的差距和前景。为此,使用相关关键字从WebofScience(WoS)检索了1763篇有关微波技术在污泥预处理中的应用的论文。然后使用不同的科学计量指数分析这些出版物。结果表明,该领域的研究包括基于微波的非热效应的应用,提高厌氧消化(AD)的有效性,以及该预处理系统的能量平衡。克服现有的技术挑战,例如细胞外聚合物的裂解,降低微波能耗,理解微波的非热效应,结合其他化学和物理方法促进污泥的AD,扩大该技术的应用,是主要的科学焦点。此外,本文全面考察了微波预处理技术在废水处理中的局限性和潜力。
