摘要

类芬顿系统和电场辅助是改进传统堆肥的两种新颖有效的策略。然而，类芬顿系统和电场辅助对堆肥腐殖质化和温室气体排放的耦合影响研究很少。因此，本研究以铁板为电极材料，通过添加CaO2颗粒构建新型电fenton系统，并评估该系统对堆肥腐殖质化和温室气体排放的影响及其潜在机制。结果表明，电- fenton体系不仅通过参与美拉德反应，有效促进更多前体物质生成腐殖质物质，而且还能有效富集电活性菌Bacillus、Geobacillus、Klebsiella等，通过加速电子转移促进腐殖质化。此外，电fenton系统有效地减少了温室气体排放。综上所述，电fenton是改善堆肥腐殖质化和减少温室气体排放的有效策略。

Electro-Fenton-assisted Camellia oleifera by-product composting for reduction of greenhouse gas emission and improvement of humification

The Fenton-like system and electric field assistance are two novel and efficient strategies to improve traditional composting. However, the coupling impacts of the Fenton-like system and electric field assistance on humification and greenhouse gas emissions in composting are rarely studied. Therefore, this study used an iron plate as the electrode material to construct a new electro-Fenton system by adding CaO₂ particles and evaluated the effects and potential mechanisms of this system on humification and greenhouse gas emissions in composting. The results showed that the electro-Fenton system not only effectively promoted more precursor substances to form humic substances by participating in the Maillard reaction, but also effectively enriched electroactive bacteria such as Bacillus, Geobacillus, and Klebsiella, which facilitated the humification by accelerating electron transfer. In addition, the electro-Fenton system effectively reduced greenhouse gas emissions. In summary, electro-Fenton is an effective strategy to improve humification and reduce greenhouse gas emissions during composting.

期刊介绍： The Chemical Engineering Journal is an international research journal that invites contributions of original and novel fundamental research. It aims to provide an international platform for presenting original fundamental research, interpretative reviews, and discussions on new developments in chemical engineering. The journal welcomes papers that describe novel theory and its practical application, as well as those that demonstrate the transfer of techniques from other disciplines. It also welcomes reports on carefully conducted experimental work that is soundly interpreted. The main focus of the journal is on original and rigorous research results that have broad significance. The Catalysis section within the Chemical Engineering Journal focuses specifically on Experimental and Theoretical studies in the fields of heterogeneous catalysis, molecular catalysis, and biocatalysis. These studies have industrial impact on various sectors such as chemicals, energy, materials, foods, healthcare, and environmental protection.
