Summary: The main objective of wastewater treatment plants is to remove pollutants from wastewater before it is discharged into waterbodies. However, these plants cannot remove all contaminants, making them concentrated sources of residual pollution. Detailed information about these plants, including their locations and characteristics, is crucial for understanding the impact of their discharges and improving their management. A global database, called HydroWASTE, has been developed to provide information on over 58,000 wastewater treatment plants worldwide.

Summary: In this study, an anammox upflow hybrid reactor was successfully used for nitrogen removal and the potential for phosphorus recovery was proposed. The researchers observed a heightoriented spatial pattern of removal capacities, biomass distribution, and HAP precipitates. They found that the intensity of HAP precipitates correlated with the amount of anammox biomass and the relative abundance of Candidatus Kuenenia, suggesting that HAP formation was influenced by the anammox reaction and organic matters. The fixed bed system was also found to play a crucial role in immobilizing the anammox biomass, organic matrix, and HAP precipitates, making HAP precipitation more achievable, effective, and practicable.

Summary: In this study, a series of Pb-Zn bimetallic catalysts with a core-shell structure were prepared using a simple chemical reduction technique. The catalyst with a composition of Pb3Zn1 exhibited the highest faradaic efficiency for formate production, reaching 95.3% at -1.26V(RHE) in an H-cell (0.5 M KHCO3) at a current density of 11.18 mA cm(-2). Notably, in a flow-cell (1 M KOH), the faradaic efficiency for formate exceeded 90% across a wide potential window, with a maximum value of 98.4%. This excellent catalytic performance is attributed to the larger specific surface area and faster electrochemical reaction kinetics of the bimetallic catalyst, as well as the synergistic interactions between Pb and Zn that improve the selectivity for formate production.

Summary: Developing highly efficient bifunctional oxygen electrocatalysts is crucial for zinc-air flow batteries. Metal-organic frameworks (MOFs) and covalent organic polymers (COPs) have emerged as promising alternatives due to their designable and controllable atomic-level structures. However, their catalytic performances are limited by conductivity and catalytic activity. In this study, nanosheet FeNi-MOF and iron phthalocyanine rich COP hybrid materials are assembled through the pi-pi stacking effect to create highly efficient bifunctional electrocatalysts. The resulting catalyst exhibits superior catalytic performance and stability, making it a promising candidate for zinc-air flow batteries.
