Embodiment 1

[0038] The treatment of embodiment one refractory organic waste water

[0039] Coating TiO on the surface of ceramic materials 2 , the fabricated photocatalytic plate 3 is horizontally placed 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 bacterial solution cultivated for refractory organic wastewater into the reactor 9 and submerge the biofilm carrier 8, and circulate in the reactor 9, turn off the ultraviolet light source 4, and inoculate it through 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, and another water pump is used to control the flow rate, and the water to be treated is pumped into the reactor to realize continuous treatment. The upper part of the reactor 9, and the wa...

Embodiment 2

[0042] The surface water remediation of embodiment two composite pollution

[0043] Coating TiO on the surface of ceramic or glass materials 2 , the fabricated 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. According to the method described in Example 1, the film-hanging and operation are carried out. After the film-hanging is successful, the complex polluted surface water is continuously pumped in 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 passing through the photocatalytic zone 2, the water body is under the action of photocatalysis, and the refractory organic pollutants are partially degraded into organic carbon sources that can be effectively used by microorganisms, which promotes the smooth remov...

Embodiment 3

[0044] The treatment of embodiment three source water

[0045] Coating TiO on the surface of ceramic or glass materials 2 , the fabricated 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. Continuously pump the source water to be treated into the reactor 9, turn off the ultraviolet light source 4, and circulate the water 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 formed, turn on the ultraviolet light source 4 to continuously perform advanced treatment on the source water to remove trace organic pollutants in the water body.

Abstract

The invention is a water treatment reactor that integrates photocatalysis and biodegradation, and a processing method thereof. A water treatment reactor integrating photocatalysis and biodegration comprises a photocatalysis plate (3) as the baffle plate between a photocatalysis section (2) at the upper part of the reactor and a biodegradation section (10) at the lower part of the reactor; an upper water hole (1) and a lower water hole (5) are opened on the photocatalysis plate; an ultraviolet source (4) is controlled by a switch and is positioned above the photocatalysis plate (3); a biomembrane carrier (8) is positioned in the biodegradation section (10); a water outlet (6) and a valve are opened on the vessel wall at the lower edge of the photocatalysis section (2); a water circulation device is arranged on the reactor (9); the photocatalysis plate shields the microbes in the biodegradation section to protect the microbes from the harm by ultraviolet light; under the joint action of the photocatalyst and the biomembrane, the organic matter that is hard to degrade can greatly increase the rate of water treatment. The reactor is characterized in compact device structure, high efficiency and high speed.

Description

(1) Technical field [0001] The invention relates to a water treatment technology, including a reactor and a method thereof, in particular to a water treatment reactor integrating photocatalysis and biodegradation and a treatment method thereof. (2) Background technology [0002] The technology belongs to a device and a method for environmental engineering, biochemical reaction engineering, environmental biotechnology, chemical reaction engineering and water treatment. With the continuous development of industrial and agricultural production and the continuous improvement of people's living standards, many natural rivers, lakes, landscape waters and other surface waters, and even drinking water sources have been polluted, and most of them have more or less formed eutrophication. Coupled with the random discharge of some industrial wastewater, many water bodies also contain a large amount of refractory organic pollutants, forming complex pollution. These pollutions lead to th...
