To investigate the effects of intermittent pH regulation on volatile fatty acid (VFA) production during kitchen waste fermentation and its impact nitrogen removal efficiency in anaerobic/anoxic/oxic (A2O) process, five experimental groups were set up (pH = 3, 5, 7, 9, control). The study examined promotion soluble chemical oxygen demand (SCOD) VFA release under different conditions their contribution to total (TN) release. Additionally, methanol was used as a control carbon source explore enhancement denitrification when broth A2O process. results indicated that neutral alkaline could enhance SCOD conversion VFAs, with more pronounced effect conditions. maximum concentrations VFAs reached 36,412 5947 mg/L, respectively. Furthermore, TN most significant conditions, being 2.39 times group. When source, Proteobacteria Bacteroidota significantly enriched. relative abundance key functional genes (napA, norB, nosZ) involved cycling enzymes ([EC: 1.7.1.15], [EC: 1.7.2.1], 1.7.2.5]) enhanced, which strengthened performance.
