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, RNO_{2}^{−}-N, RNO_{3}^{−}-N, and RPO_{4}^{3−}-P represent the removal rates of TAN, NO_{2}^{−}-N, NO_{3}^{−}-N, and PO_{4}^{3−}-P, respectively. VTAN, VNO_{2}^{−}-N, VNO_{3}^{−}-N, and VPO_{4}^{3−}-P denote the variation in TAN, NO_{2}^{−}-N, NO_{3}^{−}-N, and PO_{4}^{3−}-P after CW treatment, respectively. |
