Figure 6: Redundancy analysis (RDA) biplot showing the relationship among functional genera in the sequencing data, nutrients’ variation and removal rates, and plant growth. The first axis is horizontal, and the second axis is vertical. RTAN, RNO2-N, RNO3-N, and RPO43−-P represent the removal rates of TAN, NO2-N, NO3-N, and PO43−-P, respectively. VTAN, VNO2-N, VNO3-N, and VPO43−-P denote the variation in TAN, NO2-N, NO3-N, and PO43−-P after CW treatment, respectively.
