A flower-shaped self-expanding leaf-type photocatalytic sewage purification floating bed

Abstract

The invention discloses a flower-shaped self-expanding leaf-type photocatalytic pollution-cleaning floating bed, comprising a floating bed base, several artificial flowers (2) for purifying water, a pneumatic system and a power supply device, the floating bed base floats on the water surface (8), and the floating bed base There are several round holes on the upper part, and the artificial flowers (2) are placed in the round holes, and the lower end of the artificial flowers (2) is connected with the pneumatic system, when the pneumatic system inflates the artificial flowers (2), the artificial flowers (2) float up and out of the floating bed The matrix spreads out in the shape of a flower, and when the pneumatic system pumps air into the artificial flower (2), the artificial flower (2) sinks and gathers, and the power supply device is electrically connected to the pneumatic system. The invention adopts a pneumatic method to realize the unfolding of the artificial lotus above the water surface and the closing action under the water surface, so as to realize the alternate process of photodegradation on the water surface and convective adsorption under the water surface, which can effectively solve the problem of photocatalytic materials in the water surface. The problem of low purification efficiency caused by insufficient light in the water body significantly improves the water purification efficiency.

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
