The zero-discharge technology of nano new material wastewater aims to efficiently remove harmful substances in wastewater through effective treatment methods, and realize the reduction, resource utilization and minimization of wastewater. The technology is mainly based on physical, chemical and biological treatment methods, through a multi-stage treatment and reuse system, to ensure that the harmful substances in the wastewater are effectively removed to meet the discharge standards or reuse requirements.
Separation and removal: Specific physical and chemical methods are used to separate and remove nanoparticles from wastewater. Commonly used technologies include adsorption, precipitation, membrane separation, etc. These methods are effective in removing nanoparticles from wastewater and reducing their environmental impact.
Transformation and degradation of hazardous substances: chemical and biological methods to convert hazardous substances in wastewater into harmless or low-toxicity substances. Commonly used conversion and degradation methods include advanced oxidation, photocatalytic oxidation, biodegradation, etc. These methods can completely decompose harmful substances into harmless substances and reduce the harm to the environment.
Optimization of the reuse system: The treated wastewater needs to meet the reuse standards and be retreated through the reuse system to meet the requirements of production water. The reuse system needs to be optimized to ensure that the water quality is safe and reliable to meet the needs of the production process. Commonly used reuse technologies include reverse osmosis, nanofiltration, ultrafiltration, etc.
