Embodiment Construction
[0028] The main body of the photocatalytic reactor is a box with a top cover that can transmit ultraviolet light, and the interior is divided into multiple interconnected corridors, and the side walls and bottom plates of the corridors are filled with immobilized catalysts. The photocatalytic reactor is connected by the support plate and bracket with hinge and angle adjustment mechanism. The angle adjustment structure composed of threaded support rod and adjustment nut can freely adjust the inclination angle of the photocatalytic reactor to achieve the best lighting effect. . When the water to be treated flows through the catalytic membrane, the pollutants in the water are oxidized and decomposed under the action of solar ultraviolet radiation.
[0029] For details, please refer to the attached Figure 1-6 . The present invention includes a clean water storage tank 1, an untreated water storage tank 2, a preprocessor 3, a pump 4, a flow meter 5 and a photocatalytic reactor 6...

The invention provides a photo-catalytic oxidation water treatment device based on a solar fixed film. The device consists of a clear water storage box (1), a to-be-treated water storage box (2), a pretreater (3), a pump (4), a flowmeter (5) and a photo-catalytic reactor (6), wherein a photo-catalytic reactor main body is a box with a top cover through which ultraviolet light can penetrate; the inside of the photo-catalytic reactor is divided into multiple galleries (7) which are connected mutually; 2-5 layers of fixed film catalysts (8) are filled on the side wall and bottom flat of each gallery (7); the catalyst (8) is supported by a special stainless steel net skeleton (22) or long column type skeleton (23); and the catalyst film utilizes a partial euphotic glass fiber net as a carrier on which a permanent TiO2 film is supported. The device has the advantages of simple structure, large treatment amount, high reaction speed and low operation cost, is convenient for manipulation and stable to operate, and can be widely applied to deep treatment of drinking water and preparation of high-pure water or treatment of toxic, harmful, high-concentration and low-degradable inorganic waste water.
Description
technical field [0001] The invention relates to a new type of solar fixed film photocatalytic oxidation water treatment device. The device of the invention can be widely used in the advanced treatment of drinking water and the preparation of high-purity water, and can also be applied to the treatment of toxic, harmful, high-concentration and refractory organic wastewater. treatment or combined with other water treatment technologies. Background technique [0002] Solar energy is a resource-rich new energy source, research shows that it can be used for TiO 2 The solar ultraviolet radiation (λ<387.5nm) of photocatalytic oxidation water treatment is about 3%~4% of the total solar radiation, which can be as high as about 50W / m 2 , and solar energy is environmentally friendly and will not cause environmental pollution. Therefore, using solar energy as an energy source for photocatalytic oxidation of water treatment can not only reduce energy consumption, reduce treatment cost...
