Summary: Constructed wetland-microbial fuel cells (CW-MFCs) were built to achieve simultaneous nitrogen removal and electricity generation using wetland plant litter fermentation broths as carbon sources. The addition of fermentation broths significantly improved nitrogen removal and voltage output. The study also identified acetic acid and humic acid in the fermentation broths, which increased the abundance of functional genes associated with nitrogen metabolism and electron transfer.

The closed-circuit MFC-CWs exhibited superior removal efficiency compared to traditional CWs. Adding sponge iron to the anode layer improved the removal of NO3--N but had limited effect on MC-LR removal. The integration of MFC into CWs shows promise in controlling eutrophication and MCs pollution.

Summary: Two constructed wetland-microbial fuel cells (CW-MFC), including a closed-circuit system (CCWMFC) and an open-circuit system (OCW-MFC) with petroleum coke as electrode and substrate, were constructed to explore the effect of multiple key factors on their operation performances. The CCW-MFC system showed better performance compared to a traditional CW, achieving high removal efficiencies of COD, NH4+-N, and TN. The CCW-MFC system also exhibited a greater denitrification ability due to the presence of Thiothrix and the possible quorum sensing within the denitrifying microbial community.

Summary: Continuous online monitoring is important for ensuring reliable water quality outcomes and effective removal of microbial substances during advanced wastewater treatment processes. However, most microbial indicators cannot be continuously monitored online. This study used a combined ozonation-biological media filtration process to reduce microbial indicator concentration and developed models for predicting microbial indicator concentration changes. Machine learning algorithms were applied to identify physico-chemical predictors and their associations with microbial indicator reduction. Support vector machines (SVM) with a Gaussian kernel classifier showed superior performance in microbial removal prediction. The study provides an efficient method to predict the effectiveness of the O-3/BMF process in removing microbial indicators based on commonly measured physico-chemical parameters.

Summary: Applications of advanced oxidation processes (AOPs) in water and wastewater treatment have been of great interest. UV-chlorine (UV-Cl) is emerging as a potentially cost-effective alternative to UV/hydrogen peroxide (UV-H2O2), showing efficient degradation of emerging chemicals in contaminated water. UV-H2O2 does not have superiority over UV-Cl in terms of disinfection by-product (DBP) formation. However, more investigation and pilot-scale studies are needed to establish UV-Cl as a reliable alternative to UV-H2O2.

Summary: Green walls provide a new and on-site method for treating and reusing greywater in urban areas. This study investigated the performance of different lightweight green wall media in removing twelve emerging contaminants from greywater. The results showed that coco coir and media mix columns achieved excellent removal of all contaminants through adsorption, with some hydrophilic contaminants also undergoing biodegradation. However, further research is needed to investigate the synergetic contribution of plants and media in removing these contaminants in long-term vegetated green wall systems.

Summary: The objective of this study is to incorporate soil hydraulic properties into the erodibility factor (K) of USLE-type models. By modifying and improving the existing equations for soil texture and permeability, the study successfully included information on saturated hydraulic conductivity (Ksat) into the calculation of K factor. Using the Random Forest machine learning algorithm, two independent K factor maps with different spatial resolutions were generated. The results show that the decrease in K factor values has a positive impact on the modeling of soil erosion rates.

Summary: Atmospheric PM2.5, which can generate reactive oxygen species (ROS), is associated with cardiorespiratory morbidity and mortality. 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.
