Example Embodiment
[0038] Example 1 Treatment of refractory organic wastewater
[0039] Coating TiO on the surface of ceramic materials 2 , The prepared photocatalytic plate 3 is placed horizontally in the reactor 9, and the reactor 9 is divided into an upper photocatalytic zone 2 and a lower biodegradation zone 10.
[0040] Add the domesticated activated sludge solution or the special microbial solution cultivated for the refractory organic wastewater into the reactor 9 and immerse the biofilm carrier 8, and circulate in the reactor 9, turn off the ultraviolet light source 4, after inoculation by adsorption After 2-3 days, a mature biofilm is formed, and excess activated sludge or bacterial liquid is discharged.
[0041]After the biofilm is formed, continuous treatment is carried out, another water pump is used to control the flow rate, and the water to be treated is pumped into the reactor for continuous treatment. At the same time, the water is pumped out from the lower part of the reactor 9 through
Example Embodiment
[0042] Example 2 Surface water remediation of compound pollution
[0043] Coating TiO on the surface of ceramic or glass material 2 , The prepared photocatalytic plate 3 is placed on the upper part of the reactor 9, and the reactor 9 is divided into a photocatalytic zone 2 and a biodegradation zone 10. Introduce and operate the film according to the method described in Example 1. After the film is successfully installed, continuously pump the surface water of compound pollution for continuous treatment. The water to be treated is continuously circulated through the photocatalysis under the action of the circulating water pump 11 or the air pump 12 Zone and biological reaction zone, when the water body passes through the photocatalytic zone 2, the refractory organic pollutants are partially degraded into organic carbon sources that can be effectively used by microorganisms under the role of photocatalysis, which promotes the smooth denitrification and phosphorus removal of complex pol

[0044] Example 3 Treatment of source water
[0045] Coating TiO on the surface of ceramic or glass material 2 , The prepared photocatalytic plate 3 is placed on the upper part of the reactor 9, and the reactor 9 is divided into a photocatalytic zone 2 and a biodegradation zone 10. The water to be treated is continuously pumped into the reactor 9, the ultraviolet light source 4 is turned off, and the water is circulated in the reactor 9 through the circulating water pump 11 or the air pump 12 under the condition of no ultraviolet irradiation. After 7-14 days, let it naturally form a biofilm on the biofilm carrier 8. After the film is successfully installed, turn on the ultraviolet light source 4 to continuously and deeply treat the source water to remove trace organic pollutants in the water body.
