Flower-shaped self-unfolding vane type photocatalytic sewage purification floating bed

Abstract

The invention discloses a flower-shaped self-unfolding vane type photocatalytic sewage purification floating bed. The floating bed comprises a floating bed matrix, a plurality of artificial flowers (2) for purifying a water body, a pneumatic system and a power supply device, wherein the floating bed matrix floats on a water surface (8); a plurality of circular holes are formed in the floating bedmatrix; the artificial flowers (2) are placed in the circular holes; the lower ends of the artificial flowers (2) are communicated with the pneumatic system; when the pneumatic system inflates the artificial flowers (2), the artificial flowers (2) float upwards, float out of the floating bed matrix and are scattered in a flower shape; when the pneumatic system exhausts air in the artificial flowers (2), the artificial flowers (2) sink and are folded; and the power supply device is electrically connected with the pneumatic system. According to the invention, the unfolding of artificial lotusesabove the water surface and the folding of the artificial lotuses under the water surface are realized in a pneumatic manner; therefore, the two processes of light degradation on the water surface andconvection adsorption under the water surface are alternately carried out, the problem of low purification efficiency caused by insufficient illumination of the photocatalytic materials in the waterbody can be effectively solved, and water purification efficiency is remarkably improved.

Description

technical field [0001] The invention relates to a flower-shaped self-expanding leaf-type photocatalytic pollution-cleaning floating bed, which belongs to the technical field of water environment protection. Background technique [0002] With the increase of regional population density and the rapid development of industry and agriculture in our country, the discharge of domestic and industrial and agricultural sewage has risen rapidly, and a large amount of sewage has entered rivers and lakes at all levels, causing the pollution load of rivers and lakes to exceed the total environmental pollution. In turn, a large number of aquatic organisms will die and the water body will become stinky and black, which will have a negative impact on the quality of life of local residents and the ecological environment. In particular, industrial and agricultural wastewater often contains highly toxic, high-concentration, and refractory organic pollutants, which seriously threaten the health...

Problems solved by technology

[0006] The technical problem to be solved by the present invention is to overcome the defects of the prior art and provide a flower-shaped self-expanding leaf-type photocatalytic decontamination floating bed. It has the disadvantages of large impact, high maintenance cost, and easy to form secondary pollution. At the same time, it also solves the problems of low light intensity, small irradiation area, and insufficient interface reaction of photocatalytic materials in water. The combination of floating bed structure and photocatalytic technology can effectively Improve the ability to remove pollutants in water bodies
