Problems solved by technology

[0003] So far, the most widely used ozone catalytic oxidation treatment system is mostly based on fixed bed and fluidized bed reaction systems. Both traditional fixed bed and fluidized bed reactors have their own defects. For example, the catalytic materials in the fixed bed reactor are mainly particles, blocks, etc. However, the catalytic material in the fluidized bed reactor is mainly in powder state, and there are key problems such as difficult separation and easy loss of catalytic material. sexual problems

[0173] |1. Preparation of substrate materials|

[0174] A transition metal aluminum foil with a thickness of 200 μm was selected as the basic material for the preparation of the base material; the specific steps are as follows:

[0175] 1) drawing: such as Figure 12 As shown in a, the aluminum foil (upper and lower surfaces) is subjected to high-temperature annealing, degreasing, grinding, and pre-polishing treatment, followed by wire drawing treatment, so that the upper and lower surfaces of the transition metal aluminum foil form several substantially parallel strips with a width of about 50 ± 10nm, Stripes with a depth of 3±1nm and a spacing of 50±10nm are washed with ethanol and deionized water respectively, and dried in an oven at 50°C for later use. The obtained wire-drawn material has the following properties: Figure 12 the surface shown in b;

[0176] 2) Anodizing: use the titanium plate as the cathode, use the pretreated aluminum foil as the anode, use 50g / L oxali...

Description

technical field [0001] The invention belongs to the field of water treatment, and more specifically relates to a water body purification system and a purification method. Background technique [0002] Unlike conventional water treatment reactors, where the medium is fixed, the medium in a fluidized bed reactor is suspended by the drag force created by the upwardly flowing sewage. Therefore, the fluidized bed reactor has the advantages of increasing the liquid-solid contact area, strengthening the contact between the liquid and the medium, and increasing the liquid flow rate. Fluidized bed reactors have been widely used in sewage treatment processes, for example, the application of fluidized bed reactors in sewage ozone catalytic oxidation treatment methods. [0003] So far, the most widely used ozone catalytic oxidation treatment system is mostly based on fixed bed and fluidized bed reaction systems. Both traditional fixed bed and fluidized bed reactors have their own defec...
