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: The study found that using intertidal wetland sediments as a microbial source for CWs can effectively improve phosphorus removal rates, with bacteria such as phosphorus-accumulating organisms enhancing microbial transformation of phosphorus. However, the addition of IWS increased phosphorus loss via substrate accumulation and decreased phosphorus removal rate via plant uptake.

Summary: A series of constructed wetlands with Phragmites australis were used to evaluate the removal efficiency of nitrogen, phosphorus, and COD in the presence of different Cu2+ or Zn2+ concentrations. The results showed that increasing Cu2+ concentrations improved TN and NH4+-N removal, with an optimal concentration of 2 mg/L for nitrogen removal enhancement. Zn2+ inhibited TN and NO3--N removal due to the formation of complexes with recalcitrant organic matter. However, Zn2+ slightly improved COD removal and affected denitrification processes.

Summary: The accumulation rate of phosphorus in sediments is loading rate-dependent, with aluminum-bound phosphorus and iron-bound phosphorus playing a key role in the variability of phosphorus concentration. The increase in phosphorus sorption capacity is attributed to the rise in pH, as well as the concentrations of ammonium oxalate-extractable aluminum and iron in sediments due to wastewater input.

Summary: Despite the susceptibility of resistance development and the side effects to human health and the environment, the use of systemic fungicides has been increasing over the past decades. Many fungicides have the ability to enter water bodies and have a significant impact on non-target organisms. In order to reduce the risks associated with fungicides, researchers have explored alternative eco-friendly disease management approaches, with constructed wetlands being an effective and cost-efficient remediation technique.

Summary: The study explores the use of multiple classifiers and cloud-based computing for multi-scale forest mapping. Results show that while the multiple classifier system (MCS) approach slightly improves overall accuracy in certain cases, individual classifiers perform slightly better for specific tasks like forest type and species mapping. However, MCS approaches demonstrate robust performance in terms of per-class accuracy, presenting balanced misclassification errors across all classes.

Summary: This study investigates the evolution and autoreduction behavior of Cu species in CuCl/NaY adsorbent during vacuum thermal activation. It is found that Cu species migrate from supercages to the nearby plane of the six-membered ring connecting the supercage and sod cage during vacuum activation. At 150 degrees C, vacuum autoreduction occurs, resulting in the formation of Cu+Cl- species. The results provide reference for the preparation of pi-complex adsorbents.

Summary: Hierarchical porous system with two types of mesopores provides a solution to the diffusion limitation in conventional zeolites. Cobalt oxide impregnated hierarchical ZSM-5 zeolite samples with intra- and inter-crystalline mesopores were synthesized using two different strategies. The physicochemical properties of the modified catalysts were analyzed, revealing distinct features given by the two mesoporous configurations. Catalytic activity analysis showed that Co-oxide/ZSM-5 with inter-crystalline mesopores exhibited higher activity in methane partial oxidation reaction compared to Co-oxide/ZSM-5 with intra-crystalline mesopores.
