Ozone treatment of high-organic wastewater is a common industrial wastewater treatment method. It uses ozone gas to oxidize and decompose organic matter and convert it into harmless substances. The principle of ozone treatment of high-organic wastewater is to break the double bonds, triple bonds, aromatic rings and other chemical bonds in organic matter through the strong oxidizing ability of ozone gas, so as to decompose it into low molecular weight organic and inorganic matter. These decomposition products can be further removed by biological treatment or other physical and chemical methods to achieve the purpose of purifying water quality.
Process flow of ozone treatment of high-organic wastewater
The process flow of ozone treatment of high-organic wastewater generally includes the following steps:
1. Water quality pretreatment: preliminary treatment of wastewater to remove suspended matter, sediment and impurities to ensure the effect of subsequent treatment.
2. Ozone gas generator: Ozone gas generator is the core equipment of ozone treatment. It generates ozone gas by electrolysis of water or ultraviolet radiation.
3. Ozone reactor: Ozone reactor is a device that allows ozone gas to contact and react with wastewater. Materials such as fillers or diaphragms are usually used in the reactor to increase the contact area and improve the reaction efficiency.
4. Post-treatment of water quality: There will still be some difficult-to-degrade organic and inorganic substances in the wastewater after ozone treatment, which requires post-treatment, such as biological treatment, adsorption, ion exchange, etc.
Advantages and disadvantages of ozone treatment of high-organic wastewater
The advantages of ozone treatment of high-organic wastewater include:
1. Good treatment effect: Ozone gas has strong oxidizing ability and can efficiently oxidize and decompose organic matter to convert it into harmless substances.
2. Fast treatment speed: Ozone treatment has a fast speed and high treatment efficiency, and can purify wastewater in a short time.
3. Wide range of applications: Ozone treatment can treat various types of high-organic wastewater, including industrial wastewater, domestic sewage, etc.
4. Simple operation: Ozone treatment equipment is easy to operate, has low maintenance costs, and does not require a lot of manpower and material investment.
The disadvantages of ozone treatment of high-organic wastewater include:
1. High cost: The cost of ozone treatment equipment is high, and a large amount of funds need to be invested for construction.
2. Energy consumption: The preparation of ozone gas consumes a lot of energy, which will have a certain impact on the environment.
Application of ozone treatment of high-organic wastewater
Ozone treatment of high-organic wastewater has been widely used in various fields, including chemical, pharmaceutical, printing and dyeing, food and other industries. Ozone treatment can effectively treat high-organic wastewater, meet national emission standards, and reduce pollution to the environment. In addition, ozone treatment can also be used in water treatment, air purification and other fields, and has broad application prospects.
Conclusion
Ozone treatment of high-organic wastewater is an efficient, fast and widely applicable wastewater treatment method. It uses the strong oxidizing ability of ozone gas to decompose organic matter into harmless substances to achieve the purpose of purifying water quality. Although the cost of ozone treatment equipment is high, its treatment effect is good and the operation is simple, and it has become a widely used wastewater treatment method.
