Ozone (O3) water treatment technology can decompose organic substances in water without producing environmentally unfriendly by-products, making it a highly effective oxidizing material. As an environmentally friendly and safe application technology, it can eliminate off-putting odors and impurities in water color, and reduce the total organic content (COD) in water by approximately 50%. Overseas water departments define water quality and standards based on usage, stipulating that drinking water must be free of pathogens and toxins, yet must contain minerals. Various minerals, pH levels, turbidity, color, solubility, gases, and microorganisms all affect water quality. To enhance water quality, Europe, Japan, and the United States implemented ozone water treatment technology in the last century. China is currently beginning to utilize mature ozone water treatment technology and equipment.
In 2001, an environmental research institution with industry-standard ozone generation technology collaborated with various parties, leveraging their respective technical and research strengths in water treatment. They embarked on a study of the application of ozone water treatment technology in China. As early as the 1990s, the Ozone Technology Research Institute had begun using ozone-related technologies. This includes the development of decentralized high-quality drinking water technology, safe reuse of wastewater, and deep treatment of drinking water. Ozone materials are the nemesis of sterilization, disinfection, color removal, odor and taste elimination, algae control, oxidation of heavy metals, decomposition of organic matter, and degradation of pesticides. By helping each family enjoy healthier drinking water and cleaner water for use, and by reusing wastewater treated with "ozone water treatment," we can significantly save water resources and promote the recycling and reuse of water.
Over the past 8 years, through extensive experimental validation, we have developed different treatment solutions for various water sources—lake water, river water, reservoir water, domestic wastewater, and industrial wastewater, among others—under various application objectives. This has enhanced the technical foundation for the application of ozonation water treatment technology in China. This research is poised to address the current blind spots in the application of ozonation water treatment in China, while also promoting the wider adoption of the technology. It aims to improve the safety of water utilization in China and more effectively achieve the efficient use of water resources. It is reported that the ozonation preparation technology has seen a reduction in unit energy consumption by 2-3 times over several decades, and the prices of ozone generators have also been steadily decreasing, making the equipment more compact and conducive to promotion.
