Summary: In this study, an airlift inner-circulation partition bioreactor (AIPBR) was operated continuously for 215 days to explore methods of strengthening the performance and stable operation of the single-stage autotrophic nitrogen removal (ANR) system. The nitrogen removal rate increased with the decrease of hydraulic retention time and the increase of aeration rate, and the sludge morphology gradually changed, providing a suitable growth environment for various functional bacteria and promoting the ANR performance.

Summary: This study addressed the issues of sludge floating and uneven mass transfer in up-flow partial denitrification/anammox (PDA) reactors by implementing two strategies: adding biological carriers and applying mechanical stirring. The results showed that both strategies effectively prevented sludge flotation and deterioration of settling performance. Mechanical agitation had a more significant positive impact on PDA performance compared to the addition of biocarriers as it achieved more adequate mass transfer.

Summary: This study explored the optimal operating conditions for a sponge iron biofilter (SIBF) treating low ammonia wastewater, and found that a hydraulic retention time (HRT) of 9 h and a gas-water ratio (R) of 9:1 achieved a total inorganic nitrogen removal efficiency of 77.2%, with effluent ammonia and total inorganic nitrogen concentrations below 5 mg/L and 15 mg/L, respectively. Stable isotope tracing analysis showed that 92.8% of N2O was derived from ammonia, with nitrifier denitrification being the dominant production pathway. The microbial community analysis identified key bacteria involved in nitrogen removal in SIBF, including Nitrosomonas, Nitrotoga, Nitrospira, Dechloromonas, Thiobacillus, and Brocadia.

Summary: This study presents a new method for denitrification by coupling autotrophic bioelectrochemical partial-denitrification with anammox. It was demonstrated that nitrite can be stably accumulated and the transformation ratio from nitrate to nitrite can be improved by a small bias voltage. The nitrite and ammonium can be effectively removed through anammox. Additionally, the self-alkalization of the catholyte and the external voltage were found to be important for achieving partial-denitrification.

Summary: This study aimed to explore the feasibility of utilizing thiocyanate for the removal of nitrate and ammonium through anammox (AN) and thiosulfate-driven autotrophic denitrifiers (TSAD). The results showed that the efficient removal of nitrate and ammonium was achieved by the degradation of thiocyanate by TSAD and the cooperation with AN. The microbial cooperation increased the utilization efficiency of thiocyanate in nitrogen removal by 250%. The findings provide insight into the efficient utilization of thiocyanate in nitrogen removal through microbial cooperation.

Summary: Low-strength ammonia and temperature pose challenges to the application of the partial nitritation-anammox (PNA) process in treating mainstream wastewater. This study investigated the effects of various substrate concentrations and temperatures on nitrogen removal performance, biochemical reaction rate, and specific activity in a single-stage PNA system. The results showed that low ammonia concentration caused a decline in reaction rate and activity of anammox bacteria, while low temperature resulted in a significant decrease in the relative abundance of anammox bacteria. Changes in metabolic pathways suggest that the PNA system can adapt to low substrate concentrations and temperatures by facilitating substance transport and reducing energy consumption.

Summary: In this study, a comprehensive assessment of reactor performance, sludge characteristics, and microbial community characteristics was conducted to investigate the complex inhibitions leading to the deterioration of reactor performance in anaerobic treatment of monosodium glutamate wastewater under low COD/sulfate ratios. The decrease in gas yield was attributed to the complex competition between sulfate-reducing bacteria (SRB) and methane-producing archaea (MPA), resulting in a decreasing number of MPA. The competitive advantage of SRB for electrons led to the production of more sulfides in the reactor, further inhibiting the activity of MPA.

Summary: This review addresses the gaps in the understanding of the methanogenesis contribution, characterization techniques, and downstream processes of conductive materials (CMs)-led direct interspecies electron transfer (DIET) in anaerobic digestion (AD). It reveals that the stimulation of methanogenesis cannot be solely attributed to DIET and emphasizes the importance of accurate characterization methods for identifying the interactions involved in syntrophic metabolism. The type of CMs also significantly affects AD downstream processes. Establishing a mathematical model for DIET is identified as a central bottleneck in understanding its mechanism in greater depth.

Summary: In this study, a novel biochar supported magnesium ferrite (BC@MF) was used for the removal of Sb(III) from groundwater. The maximum adsorption capacity was found to be 77.44 mg g(-1). Inner-sphere complexation, H-bonding, and electrostatic interactions were identified as the primary mechanisms, with potential adsorption sites including C-C/C--C, C-O, and O-C--O groups, as well as Fe/Mg oxides. The adsorbed Sb(III) was oxidized to Sb(V), and the fixed-bed column system demonstrated efficient Sb removal performance.

Summary: A Fe3+/persulfate system enhanced with a natural ligand cysteine was employed for the degradation of quinclorac, which widened the effective pH range and increased the removal rate for quinclorac. The mechanism was revealed that the Fe3+/Cys/PS system can enhance the ability of degrading quinclorac by accelerating the Fe3+/Fe2+ redox cycle and generating more reactive oxygen species. The impact factors were also optimized. This study provides a promising strategy for organic contaminated water remediation with high catalytic activity and wide pH tolerance.

Summary: In this study, a novel dissolved oxygen-differentiated airlift internal circulation PNA (PNA-DOAIC) system was designed and operated to investigate the effects of organic matter on the PNA process. The results showed that an influent C/N ratio of 2.0 was optimal for efficient and stable operation. The PNA coupled with denitrification achieved high nitrogen removal efficiency, but as the influent C/N ratio increased, the activity and abundance of anammox bacteria declined, and heterotrophic bacteria became dominant. The nitrogen removal pathways shifted from PNA to the nitrification-denitrification process. This study provides important insights into the effects of organic matter on the PNA process and expands the application scope of PNA-DOAIC bioreactors.

Summary: The production of indoleacetic acid, siderophore, and ACC deaminase by phosphate-solubilizing bacteria was investigated in this research. Pot experiments using Cd-polluted soil were performed with different treatments. The findings showed that the combination of phosphate-solubilizing bacteria and orange-peel-based activator increased ryegrass height, reduced Cd ratio, and increased enzyme activity. The abundance of beneficial bacteria was also increased, which enhanced the phytoremediation of Cd-contaminated soils.

Summary: This study evaluates the performance of ozonation and adsorption as in-series processes compared to standalone processes for the removal of Contaminants of Emerging Concern (CECs) in drinking water. The combination of both processes proves to be more effective than adsorption and ozonation alone. Ozonation improves the adsorption performance of poorly-oxidizable CECs but worsens that of well-oxidizable compounds. This research highlights the importance of considering both processes in the removal of CECs in drinking water treatment plants.

Summary: The exacerbation of global warming, extreme weather events, and rapid urbanization have led to increased flooding in urban areas. China has adopted sponge city as an efficient means of preventing and controlling urban floods. Using a SWMM-FVCOM model, the hydrological reduction and control effect of sponge city construction (SPCC) within a university campus were evaluated. The study found that implementing SPCC effectively mitigates surface runoff and reduces the severity of urban flooding. However, the efficacy of runoff control decreases with longer rainfall return periods.
