Embodiment Construction

[0017] Further description will be given below in conjunction with the specific system structure diagram for realizing the method of the present invention.

[0018] Ultraviolet light is a kind of light wave radiation with certain penetrating power and lethality. The present invention uses ultraviolet C-band ultraviolet light to directly irradiate cyanobacteria in water bodies or circulating water for a certain period of time, wherein ultraviolet rays with a wavelength of 254nm are the main ones, and the intensity is 3.0-10W / m 2 , the irradiation time is 1 to 5 minutes, and the lower intensity can fully guarantee the effective inhibition of algae, while avoiding damage to other organisms in the water body.

[0019] figure 1 Shown is a schematic diagram of a floating ultraviolet light irradiation suppression system for cyanobacteria blooms. The system includes a cruise ship floating on the water surface, and an ultraviolet light irradiation device composed of a plurality of ul...

Abstract

The ultraviolet radiation method for inhibiting blue-green algae growth in water is to irradiate blue-green algae in water with ultraviolet light the ultraviolet light radiation device generates for 1-5 min, and the ultraviolet light is in ultraviolet C band of 254 nm mainly with strength of 3.0-10 w/sq m. The ultraviolet light radiation device may be mounted on pleasure boat and its ultraviolet lamp is soaked in water in the depth of 0.05-0.5 m. The present invention can inhibit blue-green algae growth effectively to prevent water bloom without harm to other aquatic life and no secondary pollution.

Description

technical field [0001] The invention belongs to the technical field of environmental protection, in particular to a method and a system for inhibiting the growth of cyanobacteria in water by ultraviolet light irradiation. Background technique [0002] Water resources are the basic material that human beings depend on for survival. With the growth of population and the rapid development of social economy, the demand for water has increased sharply, and the pollution of water resources has become increasingly serious. According to the survey in 2000, 14 of the 18 major lakes in my country have entered the state of eutrophication, such as Dianchi Lake, Taihu Lake, West Lake, East Lake, South Lake, Xuanwu Lake, Bohai Bay, Laizhou Bay, Jiulong River, Huangpu River, etc. Eutrophic water bodies are prone to algal blooms, making the water smell foul, reducing the transparency of the water body, increasing turbidity, and causing anaerobic conditions. Some algae can also secrete alga...
