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 secondary pollution. The next blue-green algae outbreak lays hidden dangers

[0006] Most of the biological methods use various algae-dissolving viruses, algae-dissolving bacteria, etc. to kill algae, or use higher aquatic plants to compete with algae to inhibit the growth of algae, and have a treatment effect on the substances in algae cells, but algae-dissolving virus , Bacteria and other variables are very large, and the risk of other ecological pollution will increase after the introduction, and the effect will be slow at the same time

[0007] In the treatment of black and odorous rivers in small and medium-sized rivers, cyanobacteria blooms are particularly prone to break out in summer, which will rapidly deteriorate the water quality of rivers that have not yet recovered, produce odors, reduce dissolved oxygen in water, and release refractory algae toxins. The appearance of oily floating substances seriously affects the senses. The existing methods will not only introduce new pollutants, but also be slow to take effect, and cannot contain the blue-green algae outbreak in the early stage
