The ozone micro nano bubble disinfection, sterilization, and algae removal technology for reclaimed water reuse is an efficient and environmentally friendly water treatment technology that combines the strong oxidizing properties of ozone and the high specific surface area of micro nano bubbles to achieve rapid and comprehensive treatment of pollutants in water. The following is a detailed analysis of the technology:
1、 Technical principles
1. Strong oxidizing properties of ozone:
Ozone (O3) is a strong oxidant with an oxidizing ability second only to fluorine. In water, ozone can rapidly decompose and produce highly oxidizing free radicals (such as OH ·), which can attack organic matter, bacteria, viruses, and other pollutants in water, oxidizing and decomposing them into harmless substances.
2. High specific surface area of micro nano bubbles:
Micro nano bubbles refer to bubbles with diameters ranging from micrometers to nanometers. These bubbles, due to their small size and large specific surface area, can significantly improve the contact efficiency and reaction rate with pollutants in the water. At the same time, micro nano bubbles release enormous energy when they rupture, further promoting the oxidation and decomposition of pollutants.
2、 Technical application
1. Disinfection and sterilization:
Ozone micro nano bubble technology can quickly kill bacteria, viruses and other microorganisms in water, destroy their cell structure, and achieve efficient sterilization and disinfection. Meanwhile, the oxidation effect of ozone can also damage the cell membrane and DNA of microorganisms, preventing their regeneration and reproduction.
2. Algae removal:
Ozone micro nano bubble technology also has a significant removal effect on algae in water. Ozone can destroy the cell walls and membranes of algae, rendering them inactive and gradually decomposing. At the same time, the disturbance effect of micro nano bubbles can also prevent excessive reproduction of algae in the water and maintain the clarity of the water.
3. Reclaimed water:
In the process of reusing reclaimed water, ozone micro nano bubble technology can effectively remove pollutants such as organic matter, inorganic matter, and heavy metal ions from water, improving the water quality standards of reclaimed water. At the same time, this technology can also remove odors, pigments, etc. from water, improving the sensory quality and taste of water.
3、 Technical advantages
1. Efficiency:
Ozone micro nano bubble technology can quickly kill microorganisms and remove pollutants in water, with high treatment efficiency and short time.
2. Environmental friendliness:
Ozone mainly generates oxygen after decomposition in water, and does not introduce new pollutants, which meets environmental protection requirements. At the same time, this technology can also reduce the use of chemical disinfectants and minimize their impact on the environment.
3. Economy:
The equipment investment for ozone micro nano bubble technology is relatively small, and the operating cost is low. Meanwhile, this technology can also extend the service life of water treatment facilities and reduce maintenance costs.
4、 Application Cases
Ozone micro nano bubble technology has been successfully applied in multiple reclaimed water reuse projects. For example, in a wastewater treatment plant's reclaimed water reuse project, this technology was used to treat secondary effluent, successfully removing pollutants such as organic matter, bacteria, and viruses from the water, and improving the water quality standards of reclaimed water. At the same time, this technology significantly improves the sensory quality and taste of reclaimed water, making it more suitable for use in urban greening, road washing, industrial cooling, and other fields.
5、 Conclusion
The ozone micro nano bubble disinfection, sterilization, and algae removal technology for reclaimed water reuse is an energy-saving, environmentally friendly, and economical water treatment technology. This technology can quickly kill microorganisms and remove pollutants in water, improving the water quality standards of reclaimed water; At the same time, this technology also has environmental and economic advantages, meeting the requirements of sustainable development. In the future, with the continuous advancement of technology and further cost reduction, this technology is expected to be promoted and applied in more fields.
