Nitrate pollution in groundwater has steadily increased globally, posing a potential threat to human health. Introduction of exogenous electron donors can significantly enhance nitrogen removal from nitrate-contaminated groundwater. Yet, conventional individual autotrophic or heterotrophic denitrification approaches have the disadvantage low efficiency high cost. This study investigated performance laboratory-scale solid-phase (SPD) permeable reactive barrier (PRB) using polyhydroxybutyrate-co-valerate (PHBV)/pyrite mixture as an donor for denitrification. Two different mass ratios (1:1 and 1:2) were established experimental setup. The results showed that under influent levels between 20 37 mg·L-1, PHBV/pyrite system at ratio 1:1 achieved maximum nitrate 97.03%, with rate 99.13 mg NO3--N NO3--N·L-1·d-1. Moreover, 1:2 reached 97.65% 111.04 NO3--N·L-1·d-1 terms optimum rate. Dissolved organic carbon was undetectable effluent both systems. superior one 1:1, implying appropriate addition pyrite mixtrophic systems could Additionally, dominant genera identified respectively Cloacibacterium Acinetobacter two systems, indicating varying modulate succession nitrogenremoving microorganisms. Specifically, favoured aerobic microbial growth, thereby enhancing biological removal. findings provided valuable alternative in-situ remediation nitrate-polluted
