Technical Field
The invention belongs to the field related to environmental protection equipment, and particularly relates to a novel double-tower ozone disinfection tower.
Background
Ozone, an allotrope of oxygen, is composed of 3 oxygen atoms, unlike ordinary oxygen, and has the molecular formula O3, which is the most powerful oxidant known as a broad-spectrum oxidant. Ozone is unstable in performance and rapidly decomposes into O2 and a single oxygen atom O at normal temperature, and the two single oxygen atoms O can be combined into O2. The monatomic oxygen is very active, has strong oxidizability and decomposition function, and can quickly kill various microorganisms such as germs, viruses and the like. Ozone oxidizing ability is one time higher than chlorine, sterilizing ability is 600-3000 times faster than chlorine, and bacteria and virus can be killed within a few seconds. The method for treating bacteria by ozone is to directly oxidize the cells of the bacteria, namely to destroy the genes of the DNA of the bacteria so as to achieve the effect of inhibition. The ozone treatment has the advantages of high speed, high efficiency, no residue, no secondary pollution and the like.
Ozone technology is both old and new, which was invented by german chemists in 1840 and was used in water treatment and disinfection industry in 1856. At present, ozone is widely used in the fields of water treatment, air purification, food processing, medical treatment, medicine, aquaculture and the like, and plays a great role in promoting the development of the industries.
However, the sewage quality is complex, the influence factors in the water are more after ozone is added, the adding amount of the ozone is not easy to determine, the adding amount is insufficient, oxygen enrichment of the water body is easily caused, and more bacteria are bred; the waste of resources is caused by overlarge dosage, and the sewage treatment cost is increased. Meanwhile, the solubility of ozone in water is very low, so that how to fully mix ozone with sewage to quickly kill bacteria is also a difficult point of ozone disinfection in domestic sewage at present.
Ozone and wastewater contact devices come in a variety of forms: microporous diffusers, water spargers, packed towers, mechanical turbine injectors, fixed helical mixers, and the like. The packed tower has good mass transfer and high treatment efficiency, and is widely applied to waste gas and wastewater treatment processes.
