Partial Nitrification and Thiocyanate-Driven Denitrification of industrial wastewater

this study sought to elucidate how micro-oxic condition, when deliberately induced under controlled loading conditions, drives microbial community self-regulation and nitrogen and sulfur (N and S) synergistic metabolism in a single-stage bioreactor treating acrylic fiber wastewater. To achieve this, we established a stepwise SCN loading regime under constant aeration, enabling a progressive transition from oxic to micro-oxic conditions.
