Ozone micro nano technology plays a certain role in wastewater treatment for decolorization and deodorization, mainly including the following points:

1. decolorization effect: Ozone micro nano bubbles have strong oxidizing properties and can oxidize and decompose the chromophores in wastewater, causing them to lose color. By using ozone micro nano bubble technology, the contact area between ozone and wastewater can be increased, and the decolorization effect can be improved.

2. Deodorization effect: The odor substances in sewage are usually volatile organic compounds and inorganic substances, such as hydrogen sulfide, ammonia, etc. Ozone can undergo oxidation reactions with these foul smelling substances, converting them into harmless substances, thereby reducing the odor of wastewater.

3. Sterilization and disinfection: Ozone micro nano bubble water has the function of sterilization and disinfection, which can kill bacteria, viruses, and other microorganisms in wastewater, preventing them from causing harm to the environment and human health.

4. Improving biodegradability: Some wastewater treatment requires biological treatment processes. Ozone micro nano technology can decompose large molecular organic compounds in wastewater into small molecular organic compounds, improving the biodegradability of wastewater and facilitating subsequent biological treatment.

The application of ozone micro nano technology in wastewater treatment to ensure its treatment efficiency and economy. Meanwhile, in practical applications, it is necessary to design factors such as the dosage of ozone, reaction time, and bubble size.
