Deep analysis of the comprehensive application scheme of experimental ozone generator and micro nano bubble generator

1、 Deep analysis of technical characteristics of experimental equipment

Experimental ozone generator: The core principle is to ionize dry oxygen or air into ozone molecules through a high-voltage electric field, and configure a gas volume regulating valve and an online monitoring module for ozone concentration to ensure that the output concentration is linearly adjustable. Experimental level functions focus on "micro precision" and "operational safety", equipped with a high-frequency inverter power control system that can fine tune ozone production; Built in exhaust gas destruction device to ensure safety; The equipment materials are mostly 316L stainless steel or quartz glass, which are resistant to oxidation and corrosion. Ozone can destroy the structure of microorganisms, decompose and produce hydroxyl radicals to enhance oxidation efficiency.

Micro nano bubble generator: The core principle is to physically cut and disperse gas in the liquid phase, generating bubbles with diameters ranging from 100 nanometers to 30 micrometers and a larger specific surface area. Its special physical and chemical properties include: long residence time, prolonged gas-liquid contact time; High dissolution efficiency, improving gas dissolution rate; Internal high pressure and rupture effect release energy to excite hydroxyl radicals; Charged characteristics, adsorbing positively charged pollutant particles.

2、 Design of Process Flow for Composite Systems

Adopting a closed-loop process of "gas source preparation water vapor dissolution release reaction". During the gas supply stage, the ozone generator uses pure oxygen as raw material and adjusts the discharge power to output ozone gas flow. In the stage of water and gas mixing, ozone gas is connected to a micro nano bubble generator, and the liquid enters the mixing chamber. Under the action of high-speed swirling shear, ozone forms micro nano bubbles and dissolves in the liquid. In the reaction treatment stage, the mixed solution enters the reaction device, and micro nano bubbles are retained to release ozone molecules and free radicals, which deeply oxidize and inactivate the target substance.

3、 Experimental application scenarios and effect analysis

Advanced oxidation degradation of organic pollutants: Combining ozone and micro nano bubble characteristics to treat difficult to degrade organic wastewater, improving ozone utilization efficiency, reducing wastewater chemical oxygen demand and total organic carbon indicators.

Deep sterilization, disinfection, and biofilm control: used for biofilm treatment of medical devices, food processing surfaces, or circulating water systems. Micro nano bubbles penetrate the biofilm and work together with ozone to remove drug-resistant strains and deep biofilms.

Agricultural breeding and root growth promotion experiment: Conduct hydroponic experiments using the sterilization and oxygenation characteristics of ozone micro nano bubble water to create a high oxygen environment for plant roots, inactivate pathogens, and improve crop germination rate and growth rate.

4、 Key control parameters of the experiment

To ensure the accuracy and reproducibility of the experiment, it is necessary to control: ozone concentration and production, adjust the generator operating current frequency and oxygen flow rate; Gas liquid ratio, adjust the ratio of generator intake to liquid intake; System pressure, maintain appropriate outlet pressure of the mixing pump; Contact time, design a reasonable hydraulic retention time based on the reaction system.
