[0024] The utility model is further described below in conjunction with the accompanying drawings and implementation modes.

[0025] First embodiment

[0026] Please refer to Figure 1 , Figure 2 , Figure 3 ,in, Figure 1A schematic structural diagram of a first embodiment of a corrugated titanium-based lead dioxide anode plate provided by the utility model; Figure 2 for Figure 1 The schematic diagram of the main body structure shown; Figure 3 for Figure 1 A schematic diagram of a partial cross-sectional structure of a body is shown. A corrugated titanium-based lead dioxide anode plate comprises: a body 1, the body 1 is wavy, the body 1 comprises a substrate 11, a transition layer 12, an activation layer 13 and an intermediate layer 14, and a convex pattern 3 is arranged on the top of the substrate 11;

[0027] A plurality of reinforcing blocks 2 are provided at the concave bends of the main body 1 .

[0028] The transition layer 12 is disposed on the outer side of the substrate 11 , the activation layer 13 is disposed on the outer side of the transition layer 12 , and the intermediate layer 14 is disposed on the outer side of the activation layer 13 .

[0029] The convex pattern 3 is a mesh pattern.

[0030] Ruthenium and iridium oxides are mixed with a binder and coated on the surface of a substrate 11. After sintering, a transition layer 12 is formed on the surface of the substrate 11. Tin oxide SnO2 and antimony oxide Sb2O5 are coated on the surface of the transition layer 12. After sintering, an activation layer 13 is formed on the surface of the transition layer 12. Alpha lead dioxide is electroplated in a lead plating bath to form an intermediate layer 14. Beta lead dioxide is electroplated in a lead plating bath to form an outer plating layer 15.

[0031] The substrate 11 is a titanium substrate, and the convex pattern is directly arranged on the titanium substrate, and the titanium substrate is formed by extrusion;

[0032] The cross section of the body 1 is a wave-shaped structure, which has the advantages of increasing strength, avoiding bending deformation of the anode plate, and increasing production compared with the existing flat plate structure;

[0033] By providing convex patterns 3 on the outer surface of the body 1, the specific surface area of ​​the anode plate can be effectively increased compared with the existing smooth plane. Under the same conditions, the real current density can be reduced, and the energy consumption can be reduced. The special shape structure can resist the thermal deformation and bending caused by excessive current, avoid the shedding of the coating or plating layer, do not pollute the tank liquid, and extend the service life of the plate;

[0034] The reinforcing block 2 is installed at the bending part of the main body 1 , so as to play a role in supporting and reinforcing the bending part, thereby preventing the bending part from bending again, thereby increasing the strength of the main body 1 .

[0035] The working principle of a corrugated titanium-based lead dioxide anode plate provided by the utility model is as follows:

[0036] Ruthenium and iridium are used as the transition layer 12 to improve the conductivity of the anode. Tin antimony oxide is used as the activation layer 13 to improve the corrosion resistance of the titanium substrate and prevent the formation of non-conductive titanium dioxide on the surface of the titanium substrate. α-lead dioxide is used as the intermediate layer to enhance the firmness of the bond between the lead dioxide coating and the electrode substrate, alleviate the generation of electrolytic distortion, and make the β-PbO2 evenly distributed. β-lead dioxide is directly electroplated on the intermediate layer 14 to form an outer coating 15, which enables the lead dioxide anode to directly oxidize and degrade organic matter on the anode surface during the treatment of organic wastewater, so that the organic matter in the sewage is directly or indirectly converted into CO2 and water through electrochemical conversion, thereby reducing pollution to the environment.

[0037] Compared with the related art, the corrugated titanium-based lead dioxide anode plate provided by the utility model has the following beneficial effects:

[0038] By setting a reinforcing block 2 at the bending part of the main body 1, it is prevented that the main body 1 is bent along the bending part during subsequent transportation or use, causing the main body to bend and deform. In this way, the bending part of the main body 1 can be reinforced during use to increase the strength of the main body 1.
