Revealing the link between evolution of electron transfer capacity of humic acid and key enzyme activities during anaerobic digestion

Xiqing Wang et al.

Summary: The study found that the electron transfer capacity (ETC) of HAs increased during anaerobic digestion process at both mesophilic (671-1479 mu mol gHA-1) and thermophilic (774-1506 mu mol gHA-1) conditions. The ETC was positively correlated with bacterial community in hydrolytic and acidogenic phases, but negatively correlated with archaeal community in methanogenic phase. Furthermore, HAs formed under thermophilic conditions had a greater influence on key enzyme activities than those formed under mesophilic conditions.

Enhanced production of short-chain fatty acids from sludge by thermal hydrolysis and acidogenic fermentation for organic resource recovery

Lei Wen et al.

Summary: This research investigated the use of thermal hydrolysis (TH) as a pretreatment to enhance fermentation and short-chain fatty acid (SCFA) production from waste sludge. The results showed that TH pretreatment promoted rapid abiotic hydrolysis and increased the production of SCFAs during sludge fermentation. Furthermore, the combination of TH and alkali pretreatment resulted in even higher SCFA production and shorter fermentation time. Microbial community analysis revealed that the microbial consortia in the TH&Alk-FM process performed better in fermentation and SCFA production compared to the NT-FMpH10 process.

Unblocking the rate-limiting step of the municipal sludge anaerobic digestion

Jiefu Wang et al.

Summary: This study analyzed the factors affecting solid reduction in anaerobic digestion systems and found that thermophilic anaerobic digestion was superior to mesophilic anaerobic digestion in terms of solid reduction when integrated with thermal hydrolysis pretreatment (THP). Adjusting the solids retention time can mitigate the impact of hydrolysis outpacing methanogenesis.

Investigating the Evolution of Structural Characteristics of Humic Acid Generated during the Continuous Anaerobic Digestion and Its Potential for Chromium Adsorption and Reduction

Xiqing Wang et al.

Summary: This study examined the structural changes and metal adsorption-reduction abilities of humic acid (HA) produced during continuous anaerobic digestion (AD). The results showed that the composition and content of HA changed during the AD process. The findings of this study not only advanced understanding of the evolution of HA and its potential for metal remediation, but also support further research towards developing an eco-friendly strategy for the remediation of heavy metal-contaminated soils using anaerobic digestate.

Mechanisms of genuine humic acid evolution and its dynamic interaction with methane production in anaerobic digestion processes

Xiqing Wang et al.

Summary: This study investigated the evolutionary dynamics of humic acid (HA) in chicken manure and corn stover in the anaerobic digestion (AD) process under different temperature conditions. It was found that the evolution mechanisms of HA differed between the two substrates, and higher temperature accelerated the humification process of HA. The concurrent decomposition and re-polymerization of HA during AD had both positive and negative effects on CH4 production.

Review on pretreatment techniques to improve anaerobic digestion of sewage sludge

V Khanh Nguyen et al.

Summary: Anaerobic digestion (AD) of sewage sludge is an efficient remediation technique, but the presence of complex floc structures and high organic matter content hinder hydrolysis. Pretreatment techniques such as mechanical, chemical, thermal, and biological processes can accelerate hydrolysis and improve AD efficiency.

Molecular mechanisms of interaction between enzymes and Maillard reaction products formed from thermal hydrolysis pretreatment of waste activated sludge

Qiandi Wang et al.

Summary: Thermal hydrolysis pretreatment is commonly used to enhance the anaerobic digestion of waste activated sludge in wastewater treatment plants. During this process, the Maillard reaction produces biorefractory organic substances that can interact with proteins, leading to changes in protein structure and enzyme activity. Spectroscopy methods and thermodynamic analysis confirm the interaction mechanisms between Maillard reaction products and proteins.

Different activation methods in sulfate radical-based oxidation for organic pollutants degradation: Catalytic mechanism and toxicity assessment of degradation intermediates

Wenqi Wang et al.

Summary: With the continuous development of industrialization, more refractory organic pollutants are released into the environment, posing serious risks to human health and wildlife. The sulfate radical-based advanced oxidation technology is widely applied in organic pollutants treatment due to its high efficiency and eco-friendly nature. Various methods for persulfate and per-oxymonosulfate activation, identification of reactive oxygen species, toxicity of degradation intermediates, and detoxification and mineralization of target pollutants induced by different reactive oxygen species are comprehensively summarized.
