Embodiment 1
[0036] Preparation of Copper-Cerium Modified Titanium Dioxide Catalyst
[0037] 1. Preparation of ceramsite carrier
[0038] Take 2.0kg of sludge, 1.0kg of clay, 1.0kg of kaolin, 1.0kg of fly ash, and 0.2kg of water glass, and mix them well to form The columnar ceramsite blank is heated in a high-temperature furnace at a temperature of 10°C to 500°C, pre-fired at a constant temperature for 30 minutes, then raised to 1100°C at a rate of 5°C / min, sintered for 20 minutes, and cooled to below 300°C at a rate of 10°C / min. Take out and cool naturally, the appearance of the porous ceramsite carrier is brick red short columnar solid particles. After inspection, there is no leaching of toxic substances, and it has good apparent density and porosity, so it can be used as a catalyst carrier material.
[0039] The surface of the prepared ceramsite ceramics is rough, loose and porous, the particle porosity is as high as 55%, and the specific surface area is 380m 2 / g; stable chemical p...
Embodiment 2
[0046] 1. Measure 1000ml of explosive waste water, adjust the pH value to 4 with 10% dilute sulfuric acid, add potassium persulfate with a molar concentration of 0.2, the amount added is 5% of the waste water, and mix well;
[0047] 2. Put a 259nm ultraviolet lamp in the water, add the copper-cerium-modified titanium dioxide catalyst prepared in Example 1 with 5% waste water, aerate with 30mL / s gas output, react for 6 hours, and the reaction ends. Detect COD, TN, SS, TNT, RDX, DNT content of wastewater;
[0048] The test results are as follows:
