Summary: The electrochemical oxidation of aqueous tris(1,3-dichloro-2-propyl) phosphate (TDCPP) using Ti/SnO2-Sb/La-PbO2 as anode was investigated. The degradation mechanisms and toxicity changes of the degradation intermediates were determined. The results showed that the degradation of TDCPP followed pseudo-first-order kinetics, with better performance at higher current density. The free hydroxy radical ( •OH) was proven to play a dominant role in TDCPP oxidation. Five intermediates were identified and further degraded over time. The toxicity of TDCPP and the intermediates significantly reduced, indicating good detoxification efficiency.

Summary: The potential risks of continuous release of anti-cancer drugs like capecitabine have gained significant attention. Understanding the removal performance and protective mechanism against emerging contaminants is crucial for wastewater treatment using anammox techniques. Capecitabine had a slight effect on nitrogen removal performance in activity experiments. Through bio-adsorption and biodegradation, up to 64-70% of capecitabine can be effectively removed. However, a concentration of 10 mg/L significantly decreased the removal efficiency of capecitabine and total nitrogen in repeated load scenarios. Metabolomic and metagenomic analyses provided insights into the biodegradation pathway and protective mechanisms of the system, including the increased presence of heterotrophic bacteria and secretion of sialic acid.

Summary: This study demonstrates that the addition of 4-chlorophenol significantly inhibits the ammonia-nitrogen removal efficiency and the activity of anammox process at different concentrations. Metagenomic analysis reveals a decrease in the abundance of KEGG pathways associated with carbohydrate and amino acid metabolism with increasing 4-chlorophenol concentration. The presence of 4-chlorophenol enhances the decomposition of extracellular polymeric substances (EPS) and bacterial debris, and partially converts 4-chlorophenol to p-nitrophenol.

Summary: In this study, a MnOx-TiO2 NTAs anode was prepared by compositing narrow bandgap manganese oxide (MnOx) with TiO2 nanotube arrays (TiO2 NTAs). Electrochemical characterizations revealed that increasing the composited concentration of MnOx improved the conductivity and reduced the oxygen evolution potential, thus enhancing the electrochemical activity of the MnOx-TiO2 NTAs anode. Moreover, the optimal degradation rate of benzoic acid (BA) was achieved by adjusting the MnOx concentration and degradation voltage. These quantitative results are of great significance for the design and application of high-performance materials for electrochemical advanced oxidation processes (EAOPs).

Summary: Due to its simple process, environmental friendliness, and low operating costs, biometallurgy has become a popular technology for metals recovering from low-grade ores and tailings. An optimized agar was used to isolate and grow functional bacteria, resulting in the successful isolation of six functional stains. These strains were further tested for their ability to leach metals from polymetallic sulfide tailings, with significant improvements observed when the strains were mixed together. The selection of leaching process should be based on tailings composition and target metals.

Summary: The present study investigated the sustainable approach for wastewater treatment using waste algal blooms. The biochar produced by the marine algae Ulva reticulata was used to remove chromium, nickel, and zinc from aqueous solutions. The study examined the adsorbents' properties and stability using SEM/EDX, FTIR, and XRD. The results showed that the biochar had high removal efficiency for the toxic metals, and the packed bed column effectively removed the heavy metal ions. The Thomas and Adams-Bohart models were found to best fit the regression values, and desorption studies were conducted to understand the sorption and elution processes.
