The nitrogen removal efficiency and distribution of microbial community structures in a denitrification process aided by zero-valent iron under low carbon-to-nitrogen ratio were assessed this study. Experimental results demonstrated that the (TNRE) increased to 96.4 ± 2.72% 63.3 4.02% after continuous addition ZVI with Fe/N 6 at C/N 3 2, respectively, which was 4% 7.7% higher compared blank control. Meanwhile, EPS production 28.43% 53.10% stimulation control group, can be used as an electron transfer medium endogenous carbon source for system. Finally, symbiotic system autotrophic heterotrophic formed ZVI-enhanced. This study propose new insights into improved ZVI.
