Embodiment 1
[0037] Embodiment 1: a kind of excess sludge loaded photocatalyst of the present invention, described photocatalyst is loaded on the excess sludge carrier, through calcining, grinding, obtains excess sludge loaded photocatalyst ( figure 1 ). The obtained excess sludge loaded photocatalyst is placed in a container containing formaldehyde, and irradiated with ultraviolet light, so as to achieve the purpose of degrading formaldehyde.
[0038] The preparation method of the above-mentioned residual sludge loaded photocatalysis comprises the following steps:
[0039] (1) Weighing: Weigh the remaining sludge carrier and TiO according to the mass ratio of 6:1 2 catalyst of light;
[0040] (2) Mixing: Mix the weighed remaining sludge carrier and photocatalyst evenly;
[0041] (3) Calcination: calcining the mixed mixture in a muffle furnace with the temperature set at 540°C;
[0042] (4) Grinding: load the remaining sludge after calcination with TiO 2 The photocatalyst is ground i...
Embodiment 2
[0050] Embodiment 2: a kind of excess sludge loaded photocatalyst of the present invention, described photocatalyst is loaded on the excess sludge carrier, after calcining, grinding, generate excess sludge load photocatalyst, the gained excess sludge load photocatalyst is placed In organic wastewater, and irradiated with ultraviolet light, so as to achieve the purpose of treating organic wastewater.
[0051] The preparation method of the above-mentioned excess sludge loaded photocatalyst comprises the following steps:
