The main principle of disinfectant is oxidation, interference with the cell membrane permeability of pathogenic microorganisms, protein denaturation of pathogenic microorganisms, destruction of the cell membrane structure of pathogenic microorganisms, interference with the enzyme system of pathogenic microorganisms, etc., to achieve the purpose of killing pathogenic microorganisms. It is recommended to use disinfectants under the guidance of a doctor.
1. Oxidation: some disinfectants can oxidize with the cellular components of pathogenic microorganisms, causing oxidative damage and sterilization. For example, hydrogen peroxide can lead to microbial death by releasing reactive oxygen molecules, destroying the cell membranes and nucleic acids of microorganisms.
2. Interference with the cell membrane permeability of pathogenic microorganisms: some disinfectants can change the permeability of the cell membrane of pathogenic microorganisms, make small molecule metabolites overflow extracellular, affect cell transmission activity and energy metabolism, and even cause cell rupture, and eventually lead to microbial death.
3, the protein denaturation of pathogenic microorganisms: part of the disinfectant can react with the protein of pathogenic microorganisms, resulting in protein denaturation and precipitation, so that the microbial loss of biological activity, to achieve the effect of sterilization.
4, destroy the cell membrane structure of pathogenic microorganisms: some disinfectants can destroy the cell membrane structure of microorganisms, so that the cell contents leak out, resulting in microbial death. For example, chloride can react with the lipids of the cell membrane, destroying the integrity of the membrane.
5. Interference with the enzyme system of pathogenic microorganisms: Many disinfectants can destroy the enzyme system of microorganisms, affect the metabolism of microorganisms, and have antibacterial and bactericidal effects. For example, certain oxidants and heavy metal salts can bind to and inactivate the sulfhydryl groups of bacteria.
Disinfectants have a certain validity period and service life and need to be replaced regularly. When using disinfectants, a single type of disinfectant should also be selected as needed.

Operating Procedures for Waste Gas Treatment Equipment
Waste gas treatment equipment is one of the essential equipment in the production process, and reasonable operating procedures are important for the normal operation of the equipment and the safety of the staff. During the operation, pay attention to the details of the equipment, pay attention to the operating status of the equipment, and take timely measures to ensure the normal operation of the equipment.
Process flow of waste gas treatment
Exhaust gas collection and transportation. First, the gas from the exhaust emission source needs to be collected and transported to the processing equipment through a pipeline or ventilation system.
The significance and purpose of sewage treatment
Protection of water resources: sewage treatment can remove or reduce harmful substances in sewage to achieve a safe level, thereby protecting the sustainable use of water resources. Improve environmental quality: By treating sewage, it can effectively reduce the content of toxic and harmful substances in the environment, prevent and reduce water and soil pollution, and protect the stability of the ecological environment.
Sewage treatment project is an important part of urban municipal construction, industrial enterprise construction or sewage treatment. Its construction must be carried out according to the national capital construction procedures. The current capital construction procedures are generally divided into several steps: project proposal, project feasibility study, project engineering design, project and equipment bidding, project construction, completion acceptance, operation commissioning and standard acceptance. These construction steps basically include the whole process of project construction, and they can also be divided into three stages.
In the process of economic development, the main rivers and lakes in China are seriously eutrophicated due to phosphorus pollution. In order to control phosphorus pollution, the State Environmental Protection Bureau has formulated relatively strict standards for phosphorus emissions.
