Cyanobacteria bloom treatment apparatus and cyanobacteria bloom treatment method

Abstract

The invention relates to the technical field of treatment of water, wastewater, sewage or sludge, particularly to a cyanobacteria bloom treatment apparatus and a cyanobacteria bloom treatment method.According to the present invention, a ship is provided with a UV/H2O2 cyanobacteria treatment device and an energy supply device, the UV/H2O2 cyanobacteria treatment device is connected to the energysupply device, the UV/H2O2 cyanobacteria treatment device comprises an ultraviolet part and a hydrogen peroxide releasing part, the ultraviolet part comprises an ultraviolet lamp tube, and the hydrogen peroxide releasing part comprises a hydrogen peroxide conveying device; and through the UV/H2O2 cyanobacteria treatment device, cyanobacteria bloom can be subjected to environmentally-friendly double treatment, no damage is generated to the environment, the treatment efficiency is high, the treatment effect is good, algae and the generated odor substances thereof can be effectively removed, andno harmful substances are produced after the treatment with the apparatus so as to achieve the environmental protection.

Description

technical field [0001] The invention relates to the technical field of water, waste water, sewage or sludge treatment, in particular to a treatment device for cyanobacteria bloom and a treatment method thereof. Background technique [0002] At present, more and more attention has been paid to the improvement of small and medium-sized rivers in cities. Most of the small and medium-sized rivers in cities have water stagnation. The rich salt content, coupled with this year's global warming phenomenon and the urban heat island phenomenon, such water bodies are particularly prone to algal blooms in spring and summer. Algae blooms refer to a natural ecological phenomenon in which algae multiply in freshwater bodies. , the outbreak of algal blooms will form green oily substances on the water body, which will not only affect the ornamental value of urban water bodies, but also release algae toxins and odor substances. Consumption of a large amount of dissolved oxygen in water leads...

Problems solved by technology

2. The method of mechanical mixing destroys the anaerobic environment in the water body and inhibits the release of nutrients in the sediment. This method requires a lot of power and consumes a lot of electric energy. At the same time, the treatment effect on the already formed algal blooms is not obvious.

3. Interception salvage method, using coagulants and fences to directly salvage blooms, this method is fast and effective, but consumes a lot of manpower and material resources

[0005] Chemical methods include pharmaceutical methods, electrochemical methods, photochemical degradation and other measures. Pharmaceutical methods mainly use various algicides, fungicides and metal ions to inhibit the growth of algae. Many components in these methods will pollute the water body. And many pollutants are difficult to remove, which has a negative effect on the ecological restoration of the river, and after the algae are killed by chemical methods, many organic matter, algae toxins, and odor substances in the algae cells cannot be removed, and they enter the water body to cause secondar...
