Description

Technical Field

[0001] The utility model belongs to the technical field of water body algae and bacteria prevention and control, and specifically relates to a water treatment device for simultaneous algae removal and sterilization. Background Art

[0002] When recycled water is reused in landscape water bodies, the residual nitrogen, phosphorus, and pathogens in the recycled water can easily lead to ecological problems such as algal blooms and pathogenic bacteria enrichment. In addition, landscape water bodies are more likely to increase the risk of excessive algae growth and pathogenic bacteria enrichment in landscape water bodies due to their openness, large water area, shallow water depth, and poor fluidity. Algal blooms and pathogenic bacteria enrichment not only damage the landscape value and recreational function of landscape water bodies, but also increase the ecological risks of water bodies and pose a threat to human health.

[0003] Traditional algae control methods, such as physical fishing, are time-consuming, labor-intensive and costly; aquatic plant restoration methods take a long time to take effect and cannot kill bacteria; chemical methods require a large amount of traditional agents and are prone to secondary pollution. In addition, existing technologies mainly focus on the removal of single algae or bacteria, ignoring the complex situation of algae-bacteria symbiosis. Moreover, traditional equipment is mostly fixed in one place and cannot effectively remove algae and pathogenic bacteria in the water, resulting in unsatisfactory prevention and control effects. For this reason, it is very necessary to develop a water treatment device that can solve the above problems and simultaneously remove algae and kill bacteria. Utility Model Content

[0006] The wavelength of ultraviolet light emitted by the ultraviolet lamp is in the C segment, mainly the ultraviolet light with a wavelength of 254nm; ultraviolet light is a penetrating light, and the energy generated can increase the activity of powdered medicine. Current studies have shown that ultraviolet C band can damage the DNA of algae cells and pathogenic bacteria, preventing their transcription and replication, and the powdered medicine activated by ultraviolet light has stronger activity, which can further damage algae cells and pathogenic bacteria, so it can effectively inhibit the growth of algae in water bodies and the enrichment of pathogenic bacteria; ultraviolet lamps can be controlled individually, and their circuit structure is waterproof.

[0007] The quantitative dosing device of the reagent effectively solves the harm of dust to operators when adding the reagent, reduces labor intensity and improves work efficiency; the specific reagent can be persulfate (PMS), which is a strong oxidant with stable structure at room temperature. After UV activation, its strong oxidizing free radicals can be better utilized.
