Denitrifying bacteria of wastewater treatment unite
We systematically evaluate vertical-flow sedimentation wastewater (VSW) and hydrolysis-acidification wastewater (HAW) from a corn starch plant to: (i) compare their denitrification performance and nitrite accumulation patterns against conventional synthetic carbon sources; (ii) establish correlations between organic matter characteristics and denitrification kinetics; (iii) characterize the dynamic responses and ecological succession of nirK- and nirS-type denitrifiers under different carbon-source regimes. This work provides actionable insights for implementing CSW in nitrogen removal systems, advancing circular bioeconomy principles while replacing synthetic carbon sources.
