Embodiment 1
[0071] Reactor see figure 1 with figure 2 , the experimental results see image 3 with Figure 4 , the morphology of the Fe-Cu catalyst is shown in Figure 5 .
[0072] Initial pH = 4.0, C H2O2 = 1.0mM, C RhB =10mg / L, the flow rate V=15ml / min, the initial dissolved oxygen concentration of the solution is 8.95mg / L. The removal rate of the first layer is 62.2%~65.3%, the removal rate of the second layer (L2) is 89.6%~93%, the removal rate of the third layer (L3) is 92.2%~93.2%, and the removal rate of the fourth layer (L4) is 93.1%~ 94.3%, and there was no significant difference (<5%) in the removal rate from the second layer to the fourth layer. The pH of the L2 layer solution increased to about 5.0, the L3 layer solution pH increased to about 5.3, and the L4 layer solution pH increased to 5.5-6.5; the ORP decreased significantly from about 380mV to about 68mV with the increase in the number of layers, and the oxidation ability showed significant Decrease trend layer by ...
Embodiment 2
[0075] Reactor see figure 1 with figure 2 , the experimental results see image 3 with Figure 4 , the morphology of the Fe-Cu catalyst is shown in Figure 5 . Initial pH = 3.8, C H2O2 = 1.0mM, C RhB =10mg / L, the flow rate V=15ml / min, the initial dissolved oxygen concentration of the solution is 8.98mg / L. The removal rate of the first layer is 80.3% to 83.7%. The pH of the L2 layer solution increased to about 4.3-4.6, the L3 layer solution pH increased to about 5.1-6.7, and the L4 layer solution pH increased to 5.4-6.5; ORP decreased significantly from about 410mV to about 45mV with the increase in the number of layers. Oxidation ability showed a significant layer-by-layer decreasing trend; the DO of L1 layer solution decreased to 1.9mg / L. Therefore, RhB is decolorized through the first water outlet after being decolorized by sponge iron-copper bimetallic catalytic reduction.

Embodiment 3
[0078] Reactor see figure 1 with figure 2 , the experimental results see image 3 with Figure 4 , the morphology of the Fe-Cu catalyst is shown in Figure 5 . Initial pH = 3.5, C H2O2 = 1.0mM, C RhB =10mg / L, the flow rate V=15ml / min, the initial dissolved oxygen concentration of the solution is 8.93mg / L. The removal rate of the first layer is 91.8%-92.2%. The pH of the L2 layer solution increased to about 4.0-4.3, the L3 layer solution pH increased to about 5.2-5.8, and the L4 layer solution pH increased to 4.7-5.7; the ORP decreased significantly from about 430mV to about 39mV with the increase in the number of layers. Oxidation ability showed a significant layer-by-layer decreasing trend; the DO of L1 layer solution decreased to 1.9mg / L. Therefore, RhB is decolorized through the first water outlet after being decolorized by sponge iron-copper bimetallic catalytic reduction.
