Embodiment 1
[0027] Embodiment 1, preparation method of particle electrode catalytic packing of three-dimensional electrolysis-photocatalysis coupled reactor: (1) pretreatment of activated carbon: sieve raw activated carbon to between 80-100 mesh, put the activated carbon after screening into 0.02 Soak in mol / L hydrochloric acid solution for 20 minutes and wash until neutral, then soak the activated carbon in 0.02 mol / L NaOH solution for 20 minutes, filter after cooling, clean with ultrasonic vibration, and then wash with distilled water several times until the cleaning liquid Pure, and finally put the treated activated carbon into an oven to dry at 80°C, take it out and cool it after 12 hours, and get the pretreated activated carbon for later use;
[0028] (2)AC / TiO 2 Preparation of particle electrode: Mix 100ml tetrabutyl titanate and 200ml absolute ethanol at room temperature, stir at a speed of 100r / min, and stir for 5min to form a light yellow clear solution A; then mix 180ml absolute...
Embodiment 2
[0032]Example 2, the preparation method of the particle electrode catalytic packing of the three-dimensional electrolysis-photocatalysis coupling reactor: (1) pretreatment of activated carbon: the raw activated carbon is screened to between 80-100 mesh, and the activated carbon after screening is put into 0.01 Soak in mol / L hydrochloric acid solution for 30 minutes and wash until neutral, then soak activated carbon in 0.01mol / L NaOH solution for 30 minutes, filter after cooling, clean with ultrasonic vibration, and then wash with distilled water several times until the cleaning solution is pure , and finally put the treated activated carbon into an oven to dry at 100°C, take it out and cool it after 12 hours, and obtain the pretreated activated carbon for future use;
