Description
Technical Field
The invention relates to the technical field of pipeline disinfection, in particular to a disinfection device for a pressure pipeline ventilation well, and particularly relates to a disinfection device for disinfecting sewage and aerosol in a pressure pipeline and a ventilation well by using ozone ultraviolet light.
Background
Ultraviolet disinfection is a common treatment process for urban sewage treatment facilities, hospital sewage treatment facilities and water supply systems at present. Ultraviolet rays are invisible light rays, generally, light with a wavelength of more than 200nm is called ultraviolet rays, and the ultraviolet rays can be further divided into UVA (315-400 nm), UVB (280-315 nm) and UVC (200-280 nm) according to different wavelengths. Among these, UVC is most easily absorbed by DNA (ribonucleic acid). UVC is used for ultraviolet disinfection. When the virus cells are irradiated with ultraviolet rays, ultraviolet rays having a wavelength of 254nm are absorbed by DNA. The adjacent thymines of the cell on the DNA strand become entangled with each other, and the new dimers prevent the replication of the correct DNA genetic code on the RNA (ribonucleic acid) strand, which is the transmitter of information and functions to transmit the DNA code to different parts of the cell. The loss of the RNA transfer function finally leads to the cell function decline and death, thereby achieving the aim of disinfection and sterilization. Whereas coronaviruses are positive-stranded single-stranded RNA viruses with a mantle. The susceptibility of coronavirus to ultraviolet light is based on the damage of internal RNA of coronavirus due to the absorption of ultraviolet energy in the internal RNA of coronavirus in ultraviolet UVC wave band. Ultraviolet disinfection is a physical disinfection mode, chemical agents are not involved in the disinfection process, and physical and chemical properties of water are not changed except for inactivating microorganisms. The disinfection process not only ensures the biological safety of water quality, but also avoids disinfection byproducts brought by other chemical disinfection modes, and also can avoid the safety influence and secondary damage on subsequent water bodies caused by excessive addition of the disinfection byproducts, thereby being a real environment-friendly disinfection mode.
Ozone has extremely high sterilization efficiency when used for sterilizing drinking water, but a large ozone dosage and a long contact time are often required when sewage is sterilized. It is generally believed that there are two ways in which ozone can be sterilized in water: one is that ozone acts directly on the cell wall of the bacteria, destroying it and causing cell death; the other is that ozone releases oxygen in a free ground state when decomposed in water, the oxygen in the free ground state has strong oxidizing capability, can penetrate cell walls, oxidize and decompose glucose oxidase necessary for oxidizing glucose in bacteria, and can also directly react with bacteria and viruses to destroy organelles and ribonucleic acid of the bacteria, decompose macromolecular polymers such as DNA, RNA, protein, lipid and polysaccharide and the like, so that the substance metabolism and the propagation process of the bacteria are destroyed; it also can penetrate cell membrane tissue, invade cell membrane, act on outer membrane lipoprotein and inner lipopolysaccharide, and promote bacterial and viral lysis and death. The photocatalytic ozone oxidation technology mainly uses ultraviolet light as an energy source and ozone as an oxidant. O3 generates hydroxyl free radical with strong oxidizing property under the action of ultraviolet light, and the strong oxidizing property is utilized to destroy the cell membrane structure of microorganism so as to achieve the effect of sterilization. When the UV/O3 finishes compounding, H2O2 is generated in the first step, and the generated H2O2 further generates hydroxyl radicals under the radiation of ultraviolet light, wherein the mechanism is as follows (1.1-1.3):
ozone has a short half-life in water, and because of its relatively poor disinfection durability, increasing the residence time of ozone gas molecules in water is critical for ozone disinfection. The bubble diameter of ozone gas molecules is reduced through the nano aeration disc, so that the diffusion efficiency and the retention time of the ozone gas molecules in water are increased, and the ozone oxidation efficiency can be effectively improved.
In addition to sewage, there are also large amounts of gases in large sewage pressure pipelines, and the production of these gases comes from several sources: pump suction, pressure reduction gas release, and sewage self-gas production. When the sewage pump station operates abnormally, the existence of gas aggravates the damage of the water hammer phenomenon, and the sewage pipeline is broken. In general, the ventilation well is arranged in practical engineering to solve the problem. However, viruses and pathogenic bacteria exist in the aerosol in the sewage pipeline and the ventilation well, and threaten the environment and the life of citizens. The small efficient disinfection device which can be placed in the pressure pipeline of the ventilating well at present has no time, and the invention in the related field mainly surrounds the removal of sediment in the pipeline, but has no invention aiming at killing viruses and pathogenic bacteria in the drainage pipeline.
