Summary: A hybrid constructed wetland system combining horizontal and vertical flow was used to treat carbon-deficient synthetic dyeing wastewater. The results showed that the system could effectively remove azo dyes from low-carbon dyeing wastewater. In the horizontal wetland, organic waste products served as the carbon source for microbial dye degradation, resulting in 90% color removal. The vertical wetland removed dye degradation organics, ammonium-nitrogen, and organic-nitrogen.

Summary: To compare the effect of different oxygen supply strategies on nitrogen removal in constructed wetlands, tidal flow constructed wetlands (TFCWs) and intermittently aerated constructed wetlands (IACWs) were investigated. Results showed that IACWs had high removal efficiencies for NH4+-N and COD, while TFCWs showed higher efficiency for total nitrogen removal due to enhanced nitrification and denitrification. The bacterial communities in TFCWs were enriched with key genera related to nitrogen transformation, while IACWs had a more complex and robust community structure.

Summary: The study evaluated the performance of a domestic wastewater treatment system using hybrid constructed wetlands under tropical climate. Regardless of plant selection and contact time, the systems were able to remove over 92% of organic matter, 88% of TSS, and 99% of pathogens. To achieve efficient nutrient removal, a combination of 4-day contact time and vegetation was necessary. Recirculation strategies were also evaluated to enhance nitrogen removal, with satisfactory results achieved by combining RS2 with the plant species Typha dominguensis.

Summary: This study investigated the effects of different factors on pollutant removal in two sets of hybrid constructed wetlands treating domestic sewage. It was found that the combination of vertical flow with horizontal flow wetlands showed better TN removal capacity, and intermittent aeration had little impact on COD and NH4+-N removal. The contribution of plants to nitrogen and phosphorus removal, as well as the influence of plant rhizosphere on nitrification activity, were significant in both wetland systems.

Summary: This study investigated the degradation of fluoroquinolones (FQs) by vertical flow constructed wetlands (VFCWs) under different hydraulic loads. The results showed that all VFCWs had high removal efficiencies of FQs under both high and low hydraulic loads. The ecotoxicity of FQs decreased significantly under low hydraulic load, and six degradation products were detected under high hydraulic load. Cytochrome P450 and enzymes with acetyl transfer activity played important roles in the degradation process, and Flavobacterium, Microbacterium, Dechloromonas were key microorganisms involved in the biological removal of FQs by VFCWs.

Summary: The study demonstrated that intermittent aeration in VFCWs significantly improved the removal efficiency of COD, NH4+-N, NO3-N, and TP compared to non-aerated setups, while setups with biochar (BC) addition and plantation were more advantageous in nutrient removal than those without BC. Moreover, the COD/N ratio of wastewater did not have a significant impact on VFCWs with BC and intermittent aeration, indicating the effectiveness of slow adsorption and fast aerobic degradation processes.

Summary: The increasing demand for sustainable energy production has led to the extensive use of solar power technology, particularly in the combustion of pollutants, CO2 reduction, photocatalysis, and hydrogen gas production. Semiconductor-based photocatalysis, such as g-C3N4, has emerged as a promising solution due to its superior electronic configuration and high performance. However, g-C3N4's photocatalytic activity is hindered by its small surface area and charge recombination. Various synthetic strategies have been employed to enhance photocatalytic performance by incorporating g-C3N4 with different materials. This review provides an overview of the latest g-C3N4-based materials and their applications in solar energy and environmental management.

Summary: Bubble aeration is widely used in water/wastewater treatment, but it consumes a lot of energy due to its low gas utilization rate. The application of micro-nanobubbles (MNB) can significantly increase gas utilization by increasing the relative surface area and gas-liquid mass transfer efficiency. In this study, a dynamic model was developed to describe the bubble behavior in water and provide guidance for upgrading bubble aeration system. The model was validated with experimental data for microbubbles, but further study is needed for nanobubble aeration.

The use of sustainable technologies for renewable fuel retention applications is beneficial in promoting clean energy usage. Conjugated microporous polymers (CMPs), a family of composites with extensive p-conjugation and microporous structure, have been recognized as important porous composites since their development in 2007. CMPs have various configurations and characteristics, making them versatile for sustainable fuel devices and environmental design. They have been employed in various applications, such as lithium ion batteries, supercapacitors, and hydrogen storage materials. The review evaluates the shortcomings of CMPs in energy production and presents potential strategies and synthetic processes for their improvement.

Summary: Anaerobic digestion technology is considered the most effective method for treating a distiller due to its environmental benefits, resource utilization, and low cost. However, microbial activity poses some limitations to this process. This paper critically reviews the microorganisms involved in the anaerobic digestion of a distiller, particularly focusing on the archaea community. The effects of operating parameters such as pH, temperature, and TAN on microbial activity and the process are discussed. Understanding microbial activity can further enhance the maturity of anaerobic treatment technology for a distiller. Additionally, the synergistic effect of different substrates and recent literature on the use of microorganisms to purify a distiller are briefly discussed for better purification and harm reduction. Further research is needed to explore the interactions between microorganisms and establish the mechanisms of microbial interactions in different environments.

Summary: This study investigates the feasibility and mechanisms of a chemical-free nanobubble-based AOP for treating organic micropollutants in water. The results show that the oxygen nanobubble AOP has a significantly higher removal efficiency compared to air and nitrogen nanobubbles. The treatment performance is not affected by pH and the presence of ions. Higher initial concentrations of the micropollutant lead to slower treatment processes, but similar removal performance is achieved in the end. The presence of organic matter reduces the removal rate of the micropollutant. The results have practical feasibility for water and wastewater treatment.
