Suspended sludge-Biofilm Niche Cooperation Enables Stable Mainstream Nitrogen Removal via Mixotrophic Partial Denitrification coupled with Anammox.
The sustainable application of partial denitrification/anammox (PD/A) under mainstream wastewater conditions depends critically on relieving the strong competition between heterotrophic and autotrophic microorganisms for substrates and ecological space. In this study, ferrous sulfide (FeS) was employed as a biofilm car...
