Embodiment Construction

[0023] Please refer to the attached Figure 1-Figure 6 . The invention includes a clear water storage tank 1, a water storage tank 2 to be treated, a preprocessor 3, a pump 4, a flow meter 5, a daylighting plate 6, a photoreactor 7 and an automatic control opening and closing device 8 triggered by a photosensitive element. The core of the photocatalytic reaction device is composed of a CPC daylighting plate 6 and a photoreactor 7 . The daylighting plate 6 is composed of 12 sets of truncated compound paraboloids (can be increased or decreased according to design requirements), and a photoreactor 7 is arranged in the center of each set of paraboloids. The elbows 9 are connected in series with each other to form a whole, and the elbows 9 are fixed by a fixing clip 10 . The bottom of the photocatalytic reactor assembly is provided with a hinge 11 and a support plate 12 for flexible connection. An angle adjustment mechanism is provided between the top of the photocatalytic react...

Abstract

An all-weather water treating device with solar energy and fixed film photocatalytic oxidation, relating to a water treating device with solar energy uninfluenced by weather, comprising: clean water storge tank (1), pre-treated water storage tank (2), pretreator (3), pump (4), flowmeter (5), lighting plate (6) and photoreactor (7). The photoreactor (7) concentric structure is formed by inner pipe (16) and outer pipe (15), which is filled with two layers of fixed film catalyst and cold cathode ultraviolet lamp (20). The outer layer (17) of the fixed membrane catalyst is fixed by spring support (21), the inner layer (18) is directly coated on the outer wall of the inner pipe (16).

Description

technical field [0001] The invention relates to a solar fixed film photocatalytic oxidation water treatment device which is not affected by the weather. The device can be widely used in the advanced treatment of drinking water and the preparation of high-purity water, and can also be extended and applied to the treatment of toxic, harmful and refractory organic wastewater. or in combination with other techniques. Background technique [0002] Solar energy is a new type of energy rich in resources, which can be used for TiO 2 The solar energy (λ<400nm) 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 can reduce energy consumption and treatment costs, and has good economic and social benefits. Ti...
