Efficient nitrogen removal from acrylic fiber wastewater achieved by the partial denitrification-anammox granule process through gradient-driven microbial remodeling.

The partial denitrification-anammox (PDA) process holds promise for nitrogen removal in acrylic fiber wastewater (AFW), yet its application stability is challenged by the sensitivity of anammox bacteria. This study applied a gradient-driven microbial…
