This study used C/N as a variable to investigate the removal effect of chlorpyrifos and the microbial community structure in the constructed system. As a result, with the increase of C/N within the range of 2-20, the removal rate of chlorpyrifos, the system matrix and the concentration of chlorpyrifos in plants all increased. The diversity of microbial community in the system was significantly affected by C/N. When C/N was 5, the microbial community diversity was the most abundant. Proteobacteria and Alphaproteobacteria were the dominant phylum and class.
