“…Phosphorus is one of the main elements causing eutrophication in water bodies ( Du et al, 2017 ; Wang et al, 2021b ). Excess phosphorus discharged into the aquatic environment from domestic, agricultural, and industrial sources can also harm aquatic life by altering the pH, lowering oxygen levels, and promoting algal growth ( Du et al, 2017 ; Wang et al, 2021b ). Microorganisms play an important role in the removal of phosphorus from CWs and can influence the form of the phosphorus ( Wang et al, 2021b ).…”

Constructed wetlands (CWs) have been proven as a reliable alternative to traditional wastewater treatment technologies. Microorganisms in CWs, as an important component, play a key role in processes such as pollutant degradation and nutrient transformation. Therefore, an in-depth analysis of the community structure and diversity of microorganisms, especially for functional microorganisms, in CWs is important to understand its performance patterns and explore optimized strategies. With advances in molecular biotechnology, it is now possible to analyze and study microbial communities and species composition in complex environments. This review performed bibliometric analysis of microbial studies in CWs to evaluate research trends and identify the most studied pollutants. On this basis, the main functional microorganisms of CWs involved in the removal of these pollutants are summarized, and the effects of these pollutants on microbial diversity are investigated. The result showed that the main phylum involved in functional microorganisms in CWs include Proteobacteria, Bacteroidetes, Actinobacteria and Firmicutes. These functional microorganisms can remove pollutants from CWs by catalyzing chemical reactions, biodegradation, biosorption, and supporting plant growth, etc. Regarding microbial alpha diversity, heavy metals and high concentrations of nitrogen and phosphorus significantly reduce microbial richness and diversity, whereas antibiotics can cause large fluctuations in alpha diversity. Overall, this review can provide new ideas and directions for the research of microorganisms in CWs.

Several biochemical cycles are performed in natural wetlands (NWs) and constructed wetlands (CWs). The knowledge of the microorganisms could be used to monitor the restoration of wetlands or the performance of the wastewater treatment. Regarding bacteria, Proteobacteria phylum is the most abundant in NWs and CWs, which possesses a role in N, P, and S cycles, and in the degradation of organic matter. Other phyla are present in lower abundance. Archaea participate in methanogenesis, methane oxidation, and the methanogenic N2 fixation. Sulfur and phosphorus cycles are also performed by other microorganisms, such as Chloroflexi or Nitrospirae phyla. In general, there is more information about the N cycle, especially nitrification and denitrification. Processes where archaea participate (e.g. methane oxidation, methanogenic N2 fixation) are still unclear their metabolic role and several of these microorganisms have not been isolated so far. The study can use 16S rDNA genes or functional genes. The use of functional genes gives information to monitor specific microbial populations and 16S rDNA is more suitable to perform the taxonomic classification. Also, there are several Candidatus microorganisms, which have not been isolated so far. However, it has been described their metabolic role in the biochemical cycles in wetlands.

“…Also, some of them are insufficient for the diffusion of pollutants (Shatat & Riffat, 2012; M. Wu, Tang, et al, 2013; X. Wu, Du, et al, 2013). Likewise, treatment technologies such as the biological treatment (Cui et al, 2021; Eom et al, 2018; Tomei et al, 2017; Zhou et al, 2020), physicochemical treatments (Liu et al, 2020; Mosquera Corral et al, 2021; Q. Wang et al, 2021) and combined (hybrid) treatments (Song et al, 2018; Panagopoulos, 2021; Xu et al, 2021; H. Zhang, Zhou, et al, 2021), constructed wetlands (CWs) (Lv et al, 2021; Sepúlveda et al, 2020; W. Wang, Wang, et al, 2020; Zhou et al, 2020), zeolite‐based treatments (Alsayed & Ashraf, 2021; Cao et al, 2021), aerobic and anaerobic treatments (Oliveira et al, 2021; Val del Río et al, 2021), and halophilic microorganisms‐assisted treatments (Capodici et al, 2018; Cui et al, 2021; Maharaja et al, 2020) are also adopted for saline wastewater treatment. Treatment and reuse of saline wastewater by CWs has become a common practice in the recent years, because of its low costs, aesthetic values, efficiency, and ecofriendly characteristics over other conventional wastewater treatment methods (Liang, Zhu, Bañuelos, Yan, Shutes, et al, 2017; X. Wang, Zhu, et al, 2020).…”

Different industrial activities such as agro‐food processing and manufacturing, leather manufacturing, and paper and pulp production generate highly saline wastewater. Direct discharge of saline wastewater has resulted in pollution of waterbodies by very high magnitudes. Consequently, an enormous number of pollutants such as heavy metals, salts, and organic matter are also released into the environment threatening the survival of human and biota. Saline wastewater also has significant effects on survival of plants, agricultural activities, and groundwater systems. Several treatments and disposal technologies are available for saline wastewater, but the selection of the most appropriate treatment and disposal technology still remains a major challenge with respect to the economic or technical constraints. Considering the sustainable management of saline wastewater, the present review is an attempt to compile the existing and emerging technologies for the treatment of saline wastewater. Among all the individual and hybrid technologies, land‐based treatment systems are proven to be the most efficient technologies considering the energy demands, economic, and treatment efficiencies. Likewise, new and sustainable technologies are the need of hour integrating both the treatment and management and the resource recovery factors along with the ultimate goal of the protection in terms of human health and environmental aspect. Practitioner points Physico‐chemical treatment technologies for saline wastewater. Combined/Hybrid technologies for the treatment of saline wastewater. Land‐based treatments as the environment friendly and sustainable method for saline wastewater treatment and disposal. Role of phytoremediation in land‐based treatment.
