Nitrogen removal through microorganisms is the most important pathway in constructed
wetlands (CWs). In this review, we summarize the microbial coupling mechanisms of …

Denitrification with non-organic electron donors for treating low C/N ratio wastewater has
attracted growing interests. Hydrogen, reduced sulfur compounds and ferrous ions are …

The application of anaerobic ammonium oxidation (ANAMMOX) process to industrial
wastewater treatment usually faces the challenge of high salinity. However, most of the …

Microbial reduction of nitrate in the presence of zero-valent iron (ZVI) was evaluated in
anoxic shake flasks to assess the feasibility of ZVI-facilitated biological nitrate removal …

Heterotrophic denitrifiers, capable of simultaneous nitrate reduction and Fe (II) oxidation,
can be applied for the remediation of nitrate and Fe (II) combined contamination in …

Partial nitrification (PN)-Anammox is considered to be the optimal nitrogen-removal process
for municipal sewage following organic carbon and phosphorus recovery. However, under …

Nitrogen pollutants in aquatic environment pose a huge threat to the ecosystem and human
health (Ding et al., 2019; Yao et al., 2019a). Microbial nitrogen removal is an economical …

The reclaimed water was usually further treated by the constructed wetland (CW) to remove
nitrogen and phosphorus before it was discharged to water bodies. In this work, the iron …

Soils are experiencing increasing pollution with arsenic (As) and phthalate esters (PAEs),
which is threatening human health. In this study, the feasibility of simultaneous remediation …

Nitrate-dependent anaerobic iron oxidation (NAIO) is a chemolithotrophic bioprocess that
converts nitrate to nitrogen gas using zero-valent/ferrous iron, making it valuable for …
