Technical Field

The utility model belongs to a cities and towns sewage disinfection technical field relates to a be used for deodorant mobile unit of sewage inspection shaft disinfection, specifically relates to one kind through supersound, ultraviolet catalysis and ozone nanometer bubble composite technology realize the interior sewage of inspection shaft pipeline and the deodorant device of aerosol disinfection.

Background

The novel coronavirus with strong infectivity outbreaks and spreads in 1 month in 2020, the possibility of virus residue may exist in the drainage pipeline of the district where the new coronavirus patient is located, and the potential hazard is generated to the life health of residents in the district, operators of urban sewage treatment facilities, environmental protection employees and the like, and enough attention must be paid.

Ultraviolet disinfection is a common treatment process for urban sewage treatment facilities, hospital sewage treatment facilities and water supply systems at present. Ultraviolet light is invisible to the naked eye, and light with a wavelength of more than 200nm is generally called ultraviolet light, and can be further divided into UVA (315-400 nm) and UVB (280-E &) according to different wavelengths

315nm) and UVC (200-280 nm). 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. Avoids disinfection by-products caused by other chemical disinfection modes, and can also avoid the safety influence and secondary harm to subsequent water bodies caused by excessive addition of the disinfection by-products.

Ozone has a very high efficiency when used for drinking water disinfection. 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. O is₃Generating hydroxyl radical with strong oxidizing property under the action of ultraviolet light, and destroying microorganism by using the strong oxidizing propertyThe cell membrane structure of the substance then achieves the effect of sterilization. No matter the hydroxyl free radical is decomposed by the ozone or the hydroxyl free radical formed after the ultraviolet light catalysis, the malodorous substances such as ammonia gas, hydrogen sulfide, methyl mercaptan and the like in the odor can be oxidized, so that the odor in the pipeline can be removed. UV/O₃On completion of the compounding, the first step produces H₂O₂Generation of H₂O₂Further generating hydroxyl free radicals under the radiation of ultraviolet light, wherein the mechanism is as shown in formula (1.1-1.3):

ozone has a short half-life in water, and because of its relatively poor disinfection durability, it is critical to increase the residence time of ozone gas molecules in water 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.

There is the possibility that coronavirus spreads in the sewer of hospital and suspected patient place isolation point and the inspection shaft at present, and the deodorant mobile unit of small-size high-efficient disinfection that can place in the inspection shaft is few, and the utility model of relevant field mainly centers on cleaing away of deposit in the pipeline, and does not have the utility model to killing virus and pathogenic bacterium in the inspection shaft.
