With the rapid development of the new energy industry, the demand for lithium-ion batteries in the field of portable devices, reserve power supply and electric vehicles continues to climb. However, the treatment of wastewater generated during the production of lithium batteries has become an environmental challenge that cannot be ignored. As an advocate of ‘value-based environmental management’, Cognex has developed a mature wastewater treatment process for lithium batteries, and by combining it with advanced industrial water filters, the treatment efficiency and environmental benefits have been improved.
Lithium battery wastewater sources and characteristics
Lithium battery wastewater mainly comes from the production process of production wastewater, cleaning equipment water and cooling water. This kind of wastewater has the characteristics of small water volume, complex composition, poor biochemistry and certain toxicity. Especially the ternary precursor wastewater, its salt component is complex, easy to scale, difficult to deal with, is the key field of lithium environmental protection.
Lithium wastewater treatment process usually includes the following steps:
1. **Primary treatment**: using chemical precipitation and industrial water filters to remove suspended particulate matter and bio-organic matter from the wastewater, and reduce turbidity and organic matter content.
2. **Intermediate treatment**: removes heavy metal ions and other toxic and harmful substances from wastewater using ion exchange and membrane separation technology.
3. **Advanced treatment**: further removes difficult-to-biodegrade organic substances through advanced oxidation and biodegradation.
4. **Disinfection treatment**: using ultraviolet sterilisation and ozone disinfection to remove bacteria and viruses from wastewater, ensuring that wastewater meets national discharge standards.
Application advantages and types of industrial water filters
In the lithium battery wastewater treatment process, industrial water filters are indispensable and important equipment. They can efficiently remove suspended particles, impurities and toxic substances in the wastewater to provide protection for subsequent treatment. The following are several major types of industrial water filters and their advantages:
1. **Bag filter**:
Advantages: suitable for the treatment of wastewater containing a large amount of suspended and particulate matter, featuring a large filtration area, high treatment capacity, simple operation and easy maintenance.
Application: widely used in the primary treatment stage to remove large particles and suspended matter.
2. **Carbon filter**:
Advantages: capable of adsorbing organic matter and odours from wastewater, especially suitable for use in the advanced treatment stage. The high adsorption capacity of activated carbon effectively removes organic pollutants that are difficult to degrade.
Application: Used in the advanced treatment stage to ensure wastewater purification.
3. **Self-cleaning filter**:
Advantages: suitable for continuous treatment process, it can automatically clean the filter, ensuring filtration efficiency while reducing manual maintenance. This kind of filter is especially suitable for wastewater treatment systems that have large treatment volumes and require stable operation.
Application: Provides continuous and stable filtration in intermediate and advanced treatment stages.
4. **Multi-media filter**:
Advantage: filtration with multi-layer filter media, capable of efficiently removing suspended particles and colloidal impurities from wastewater. Commonly used in the primary and intermediate treatment stages of wastewater.
Application**: primary and intermediate treatment stages to ensure further purification of water quality.
5. **Ultra-filtration membrane filter**:
Advantages: Adopting ultrafiltration membrane technology, it is able to remove bacteria, viruses and large organic molecules in wastewater, and is applicable to the advanced treatment stage to ensure that wastewater reaches a higher purification standard.
Application: advanced treatment stage to ensure the quality of the effluent.
