The denitrification process plays an important role in improving water quality and is a
source/sink of nitrous oxide to the atmosphere. The second important rate-limiting step of the …

Constructed wetlands are nature-like engineering systems implemented to treat wastewater
through physical, chemical, and biological processes under controlled environments. In …

The dominant ammonium bacteria established in different crop rotations are directly related
to the conversion and utilization of nitrogen (N) in paddy soil. This study investigated the …

A two-stage treatment system that included vertical flow (VF) and free-water surface (FWS)
constructed wetlands was investigated for the dual purposes of sewage treatment and …

Excessive nitrogen has been a global concern to cause lake eutrophication. The
denitrification and anammox processes are considered to be effective biological pathways …

Subsurface-flow constructed wetlands (SSF CWs), which include horizontal subsurface–flow
constructed wetlands (HSSF CWs) and vertical subsurface–flow constructed wetlands …

Denitrification in river sediments plays a very important role in removing nitrogen in aquatic
ecosystem. To gain insight into the key factors driving denitrification at large spatial scales, a …

Heavy metals are widely detected in natural environments, however their impacts on
denitrifier community in freshwater ecosystem remain unclear. The present study …

ABSTRACT nirK-type and nirS-type denitrifier communities mediate the conversion of nitrite
to nitric oxide, which is the key step in denitrification. Results of previous studies have …

The incineration of municipal solid waste has been important in waste management, but it
raises another environmental issue concerning residue treatment. This study describes an …
