Device used for removing algal toxin in water body with high intensity ultraviolet light-hydrogen peroxide

Abstract

The invention relates to a device used for removing algal toxin in water body with high intensity ultraviolet light-hydrogen peroxide. The device comprises a fiber filtering system, a photocatalysis degradation reactor, a medicine adding system, and a high intensity ultraviolet light system; the fiber filtering system is connected with the photocatalysis degradation reactor through a water inlet pipeline, and is used for interception, adsorption, and filtration of suspended particles in raw water, and filtered water is introduced into the photocatalysis degradation reactor through the water inlet pipeline; the medicine adding system is connected with the photocatalysis degradation reactor, and is used for introducing hydrogen peroxide into the photocatalysis degradation reactor for catalytic oxidation with the filtered water; the high intensity ultraviolet light system is arranged above the photocatalysis degradation reactor, and is used for emitting high intensity ultraviolet light for radiation on filtered water in the photocatalysis degradation reactor, so that in catalytic oxidation reaction, complete oxidation degradation of algal toxin is realized, and algal toxin toxicity isreduced. The above technology is capable of increasing reaction rate, and improving removing efficiency on algal toxin in slightly polluted water sources, and can be taken as an emergency technologymethod in water supply technology.

Description

technical field [0001] The invention belongs to the technical field of water treatment, and in particular relates to a device for removing algae toxins in water with high-intensity ultraviolet light-hydrogen peroxide. Background technique [0002] With the eutrophication of global water bodies, cyanobacteria blooms have successively appeared in water sources in many countries and regions. When cyanobacteria blooms occur in a large area, the normal physiological metabolic process of cyanobacteria cells will produce a large amount of algal toxins. Due to its own chemical characteristics, cyanotoxins have potential hazards such as teratogenic and carcinogenic effects through damage to chromosomes. There are many kinds of algal toxins produced by algae, such as microcystins, coccins, toxoid-a, lipopolysaccharide and toxoid-a(S), among which microcystins (hereinafter referred to as MC) account for the largest proportion. And the most serious harm, it can secrete highly toxic he...

Problems solved by technology

However, compared with advanced oxidation reactions such as Fenton and Photo-Fenton, the conventional UV / H 2 o 2 The process is not effective in degrading chemically stable organic matter, there are problems such as low reaction rate and long hydraulic retention time, and the effect is not significant for large-scale algal blooms
