Technical Field

[0001] The utility model relates to the technical field of rural domestic sewage treatment, and more specifically, to a novel rural domestic sewage photocatalytic integrated treatment device. Background Art

[0002] Photocatalytic technology uses visible light to cause semiconductors to undergo photocatalytic reactions. The generated hole-electron pairs react with water molecules to generate hydroxyl radicals, which oxidize and remove organic pollutants. Due to the abundance of solar energy resources, photocatalytic oxidation is a relatively efficient treatment method that can remove pollutants from rural domestic sewage with minimal resources. Therefore, relevant personnel often use photocatalytic integrated treatment devices to treat rural domestic sewage.

The utility model has a short reaction time and high treatment efficiency; when the photocatalytic reaction tank is added, the pollutants are further degraded under the action of photocatalysis, so that the effluent water quality is better.

[0004] The above patent has the following defects during use:

[0005] The position of the ultraviolet lamp in the photocatalytic reaction pool is fixed, which is not convenient for flexible movement, resulting in a fixed lighting range and prone to dead spots. As a result, the photocatalyst in the dead spot area is not easy to receive light to work, causing the photocatalytic reaction to be insufficient and comprehensive, thereby reducing the efficiency of the photocatalytic reaction. Therefore, there is an urgent need to improve the technology of the photocatalytic integrated treatment device to improve this equipment.
