Summary: This study proposed a novel and high-efficiency strategy, freezing followed by low-temperature thermal treatment, to significantly promote short-chain fatty acids (SCFAs) production from waste activated sludge. The maximal production of SCFAs was achieved with a shortened retention time, and the potential carbon source recovery was increased compared to traditional freezing/thawing treatment. Additionally, the strategy accelerated the solubilization and hydrolysis steps of the sludge and enriched acid-producing microorganisms.

Summary: Waste activated sludge (WAS) is a byproduct of wastewater treatment plants, and finding a low-cost and environmentally friendly technology for its disposal is a challenge. This study proposes a stepwise freezing and thawing treatment to increase the production of short-chain fatty acids (SCFAs). Mechanistic studies show that this treatment method can accelerate the solubilization of extracellular polymeric substances (EPSs) and microbial cells, promote the hydrolysis process, and enrich functional microorganisms. In addition, this treatment method can inhibit methanogenesis, benefiting the accumulation of SCFAs.

Summary: This study proposed a citric acid (CA) treatment strategy for improving short-chain fatty acids (SCFAs) production from waste activated sludge (WAS), with the optimum SCFAs yield reaching 384.4 mg COD/g VSS with 0.08 g CA/g TSS addition. The biodegradation of CA contributes to the yield of total SCFAs, especially acetic acid. The presence of CA enhances sludge decomposition, fermentation substrate biodegradability, and the abundance of fermenting microorganisms.

Summary: This study aimed to identify the contributions of hydrolyzed products of K2FeO4 on SCFAs production. The results showed that K2FeO4 did not execute dual functions of oxidization and alkalinity in promoting SCFAs production. The inhibition effects of K2FeO4 and its hydrolyzed products on the methanogenesis stage could be relieved during a longer sludge retention time, further confirming that dual functions of K2FeO4 were not obtained.

Summary: A new strategy based on thiosulfate pretreatment was proposed to enhance short-chain fatty acids (SCFAs) production during anaerobic fermentation (AF) of waste activated sludge (WAS). The addition of thiosulfate significantly improved the disintegration of WAS, leading to increased SCFA yield. This was achieved through the binding of thiosulfate to organic-binding cations, dispersing the extracellular polymeric substance (EPS) structure and causing cell lysis. The enzyme activities and gene abundances showed enhanced hydrolysis and acidogenesis, while methanogenesis was suppressed. This cost-effective and efficient strategy provides a new approach for resource recovery through thiosulfate-assisted WAS AF.

Summary: Maximizing resource recovery by improving anaerobic treatment efficiency of waste activated sludge is crucial for reducing carbon emissions. This study proposed the co-treatment of waste activated sludge with sulfite-laden wastes and mackinawite to enhance anaerobic fermentation performance. The experimental results demonstrated that FeS/sulfite pretreatment promoted SCFAs production by decomposing sludge flocs, increasing key hydrolytic enzymes, and altering the functional traits of microorganisms.

Summary: This study explored the potential effects of the pollutant carbamazepine (CBZ) on anaerobic fermentation of waste activated sludge. The results showed that CBZ at environmental levels slightly promoted the production of short-chain fatty acids (SCFAs), but high doses of CBZ decreased the production of SCFAs. The abundance of certain functional traits changed during CBZ exposure, and the adverse effect was sustained due to CBZ being non-degradable during anaerobic fermentation. A regulation strategy using persulfate was proposed to mitigate the toxicity of CBZ, and it achieved a removal rate of 83.7%.

Summary: The discharge of organic wastewater is a serious threat to the ecosystem and human health. Advanced oxidation processes (AOPs) have been extensively studied for their effective removal of recalcitrant organic pollutants in wastewater treatment. In particular, the use of iron oxide hydroxide (FeOOH)-mediated AOPs systems has gained popularity due to their excellent catalytic performance and wide applicability. This review presents the recent progress of FeOOH-based catalysts in organic wastewater treatment, with a focus on photocatalytic oxidation, Fenton-like oxidation, catalytic ozonation, and persulfates activation processes. The review also discusses the diverse crystal phases of FeOOH and the main aqueous chemistry factors affecting the degradation efficiency of FeOOH-mediated AOPs. The review concludes with a brief summary of application tips and proposes future prospects for the application of FeOOH-mediated AOPs in organic wastewater treatment.

Summary: Frequent transfer and transformation occur between material flow, energy flow, and information flow in complex engineering systems, resulting in complex coupling relationships. Abnormal coupling of flows can lead to flow problems and system function failure. In this study, a flow transfer and transformation model was proposed to analyze flow problems by categorizing the attributes of flows. The polychromatic sets theory, an information processing mathematical tool, was introduced to explore and determine flow problems in complex engineering systems. Three solution strategies were proposed based on different manifestations of flow problems. A process model for flow problem judgment and a solution strategy for complex engineering systems were constructed and validated using a case study of a tubular feeding machine system in a large-scale integrated marine resource survey ship.

Summary: This study investigates the impact of wax on hydrate formation and dissociation in water-in-oil emulsions. Experimental results show that wax forms a shell barrier on the oil-water interface, increasing transfer resistance, and decreases water droplet size, increasing the oil-water interface area. Wax exhibits dual regulation on hydrate formation, with a dominant inhibition effect at concentrations above 6 wt%. Wax also dominates the regulation of hydrate dissociation, increasing the difficulty of hydrate plug removal. These findings are valuable for hydrate risk assessment and flow assurance design in deep-water oil and gas fields.

Summary: Metal components have significant impacts on the generation of persistent free radicals (PFRs) in biochar. This study investigates the effect of interactions among metal components on the formation of PFRs during biomass pyrolysis. The results show that the coupling of Fe with Co and Ni increases the abundance of PFRs in iron-containing biochars (IBCs), while Zn inhibits PFRs generation. Persulfate activation experiments confirm that PFRs are critical redox sites. NiFeO/BC is identified as a more efficient catalyst for PFRs activation. This study provides new methods for regulating PFRs in biochar and advances the understanding of metal-containing biomass pyrolysis processes.

The study found that both the mass concentration of PM2.5 and the DTT activity were higher during the heating season than during the nonheating season. Combustion sources were the primary contributors to DTT activity during the heating season, while secondary formation dominated during the nonheating season. The study also revealed that biomass burning had the highest inherent oxidation potential among all sources investigated.

Aluminum was found in tumor areas of 24% of patients and was associated with epithelial to mesenchymal transition (EMT) and cell death. Additional analyses revealed higher tumor mutational burden and mutations in genes related to EMT and apoptosis in aluminum-positive colon cancers. Understanding the molecular mechanisms of aluminum toxicity may improve strategies for the management of colon cancer patients.
