“…It was concluded that CWs with plants not only benefit removal efficiency in the long term but can also help delay clogging. One group of researchers reviewed the influence of substrate type and plant species on clogging issues in CWs (Miranda, Teixeira de Matos, Pimentel de Matos, Saraiva, & Teixeirae, 2019). Clogging typically occurs from inorganic solids that are caused by the disintegration of substrates.…”

This article presents an update on the research and practical demonstration of wetland-based treatment technologies for protecting water resources and environment covering papers published in 2019. Wetland applications in wastewater treatment, stormwater management, and removal of nutrients, metals, and emerging pollutants including pathogens are highlighted. A summary of studies focusing on the effects of vegetation, wetland design and operation strategies, and process configurations and modeling, for efficient treatment of various municipal and industrial wastewaters, is included. In addition, hybrid and innovative processes with wetlands as a platform treatment technology are presented.

“…No entanto, a maior parte da área preservada está em terras indígenas e na Amazônia, áreas onde o ciclo tradicional de alteração de uso do solo ainda não ocorreu -são áreas à espera da exploração da madeira, seguida da pecuária, para a chegada da soja (DARANCO et al, 2012;SCHREIBER, 2019;TEIXEIRA, 2019).…”

“…Na busca dos melhores desempenhos dos SACs para o tratamento de águas residuárias, pesquisadores têm estudado diferentes tipos de culturas nos SACs, principalmente gramíneas, em razão da alta produtividade e grande capacidade de remover nutrientes (N, P e K) e sódio da água residuária. Diversos trabalhos utilizando gramíneas forrageiras tropicais, como os capins tifton 85 (MATOS et al, 2010a(MATOS et al, e 2010FIA et al, 2011;FIA et al, 2017;FIA, et al, 2020;MIRANDA et al, 2019; e elefante (MATOS, et al 2008e 2010a, MIRANDA et al, 2019, têm demonstrado elevada eficiência como extratores de nutrientes e poluentes de águas residuárias de suinocultura tratadas em SACs. Em razão da escassez de dados a respeito dessa gramínea em SACs, objetivou-se, com a realização deste trabalho, avaliar a eficiência de sistemas alagados construídos, cultivados com capim Jiggs (Cynodondactylon (L.)

“…The substrate plays a central role in the process of removing pollutants in the constructed wetland, and is an important condition for the wetland to exert good hydraulic conductivity (Miranda et al 2019;Wang et al 2020). Most wetlands use a combination of multiple substrate gradations (Prochaska & Zouboulis 2006;Fu et al 2020).…”

The water body inside the constructed wetland is affected by various factors, and the flow state is relatively complicated. There will always be a certain degree of low velocity area and rapid outflow phenomenon, which makes part of the space in the wetland unable to be effectively used. Based on Computational Fluid Dynamics (CFD) technology, this paper uses Fluent's porous media model and discrete phase model to establish a hydrodynamic model of up and down baffled subsurface flow constructed wetland system. The internal flow field of the wetland is simulated, and the hydraulic performance of different baffle settings and substrate laying methods in the wetland is systematically evaluated. The results show that: up and down baffled subsurface flow constructed, with the same number of baffles, the hydraulic efficiency of the first baffle at the lower part of the substrate will be greater. Compared with the position of the baffle, the increase in the number of baffles does not significantly improve the hydraulic efficiency of the constructed wetland. The substrate layer thickness ratio has a significant effect on the two parameters of the variance of the hydraulic residence time distribution (σ2) and the flow divergence (σ02). By increasing the thickness of the middle substrate, the low flow rate phenomenon caused by the small porosity substrate area of the upper layer and the rapid outflow phenomenon of the lower substrate can be improved to a certain extent, the utilization efficiency of the middle substrate layer is improved, and the hydraulic performance is increased. The research results are of great significance for improving the utilization of wetland space and ensuring its efficient decontamination and purification function.
