Summary: Constructed wetlands (CWLs) are widely used for water environment protection, and the animals in CWLs play a crucial role in improving treatment efficiency, maintenance, and management, as well as affecting the removal of pollutants. The characteristics of CWL animals can be used for biological monitoring, while also promoting the conservation of wetland biodiversity.

Summary: This paper presents the diagnosis and management proposal for the Valsequillo wetland in Mexico. The wetland is dominated by water hyacinth which reduces the pollutant load of the water. An annual harvest plan is proposed, but the ideal amount of biomass to harvest is unknown. Through modeling and analysis, it was found that for the desired removal of total phosphorus or chemical oxygen demand, 274 ha or 306 ha of aquatic plants must be harvested, respectively.

Summary: By optimizing wetland structures, new wetland structures have been proposed to improve water level control and runoff treatment. The removal effect of composite and tandem wetland structures is significantly better than that of general vertical flow structures, with the composite structure performing better in the removal of heavy metals, petroleum substances, and COD.

Summary: Clogging is a key problem in constructed wetland (CW) technology, but there is a lack of systematic research on its evolution, hot spots, frontiers, and classifications. This study conducted a comprehensive review using published references and analyses to bridge these research gaps. The findings provide insights into the hot directions and cutting-edge trends of CW clogging, as well as methods for monitoring and evaluating the problem.

Summary: Located in an arid region, Morocco is facing water scarcity challenges. Constructed wetlands (CWs) are a suitable technology for wastewater treatment and reuse in remote rural areas. Studies showed that CWs have high removal efficiency for conventional contaminants, heavy metals, and emerging pollutants. However, microbial contamination removal is challenging and requires additional treatment.

Summary: This study conducted a life cycle impact assessment of two different decentralized water treatment systems in Belgium using the Life Cycle Assessment tool. The results showed that these systems had a lower impact on the environment compared to their conventional alternatives in most impact categories. Therefore, decentralized water treatment systems can be considered environmentally beneficial under certain conditions.

Summary: The loss of nitrogen and phosphate fertilizers in agricultural runoff is a global environmental concern, and constructed wetlands have been increasingly used to address this issue. Optimal substrates for constructed wetlands include gravel, zeolite, and slag, while emergent plants are the most commonly used species. Recommendations for substrate, plant species, and site selections are provided in this review.

Summary: This study investigated the dynamics of microplastics (MPs) in a newly established surface flow constructed wetland (CW) that receives 1.4 million liters per day of secondary treated wastewater. The study found that most MPs were synthetic fibers and fragments in the size range of 100-1000 micrometers. The CW effectively retained MPs, but the accumulation of MPs in sediments and substrate needs to be considered.

Summary: Climate change presents challenges for agricultural water resources in terms of both quantity and quality. The use of reclaimed water in agricultural irrigation is seen as an adaptation measure. Nature-based solutions have been found to be effective in facilitating water reclamation and reuse, but improvements are needed in water quality. Recommendations were made to enhance system performance and ensure adequate water quality for agricultural reuse.

Summary: This study assessed the spatial distribution and accumulation concentrations of nutrients and contaminants in macrophytes in a constructed wetland as a performance indicator for wetland functionality and management. The results showed that concentrations of water chemistry parameters increased with distance from the inflow, while the height and biomass of macrophytes decreased with distance from the inflow.

Summary: The performance of constructed wetland is influenced by factors such as type, vegetation, hydraulic load, and media. This review discusses the technology and treatment of various types of wastewater, comparing the efficiency and cost-effectiveness of constructed wetlands with other treatment technologies. Further research is suggested to improve the selection of media, plants, engineering design and automation in constructed wetland systems.
