Introduction
Waste liquid treatment methods and technical requirements in waste battery treatment
1. Standard scope and applicability
This standard specifies the terms and definitions of waste liquid treatment and disposal in waste battery treatment, electrolyte treatment and disposal methods, waste liquid treatment and disposal methods generated in the process of metal ion reuse, and environmental protection and safety requirements. It is applicable to the treatment and disposal of waste liquid in the recycling of waste lithium-ion batteries and waste nickel-hydrogen batteries.
2. Waste liquid treatment and disposal methods
| Treatment methods | Scope of application | Process flow | Technical requirements |
|---|---|---|---|
| Electrolyte treatment and disposal methods | Mainly for the electrolyte in waste lithium-ion batteries and waste nickel-hydrogen batteries, including carbonate organic solvents and electrolytes (such as lithium hexafluorophosphate). | The primary combustion decomposes organic matter such as electrolyte and binder, and the secondary combustion removes harmful gases. The waste gas is sprayed with alkali solution for absorption and then discharged in compliance with the emission standards. | The combustion temperature is controlled at 500℃~600℃ (primary) and 1200℃~1800℃ (secondary), and the concentration of lime milk is 5%~10%. |
| Treatment and disposal methods of waste liquid generated during the recycling of metal ions | Mainly treat waste liquid containing COD, fluoride, ammonia nitrogen and metal elements such as nickel, cobalt, manganese, and copper. | Adjust the pH value, recover ammonia through the distillation tower, add flocculants for sedimentation treatment, and the filtrate enters the sewage treatment system. | The pH is controlled at 11.5~12.5, the tower bottom temperature is 102℃~110℃, and the tower top temperature is 94℃~100℃. |
3. Environmental protection and safety requirements
Case analysis: Environmental protection requirements in waste battery treatment
- Waste gas emissions must comply with the "Industrial Furnace Air Pollutant Emission Standard" (GB9078) and the "Integrated Air Pollutant Emission Standard" (GB16297).
- The pollutant emission concentration after waste liquid treatment must comply with the "Integrated Wastewater Emission Standard" (GB8978), and the cobalt ion emission concentration must comply with the "Copper, Nickel, Cobalt Industrial Pollutant Emission Standard" (GB25467).
- The identification and disposal of solid waste must be carried out in accordance with the "General Rules for the Identification of Hazardous Wastes" (GB5085.7), and hazardous waste must be handled by qualified units.
4. Recommendations for the implementation of the standard
To ensure the effective implementation of the treatment and disposal methods for waste liquid in waste battery treatment, it is recommended that:
- Establish a complete monitoring system and regularly test the treatment effect of waste liquid.
- Strengthen employee training to ensure that operators are familiar with the process and technical requirements.
- Introduce advanced equipment and technology to improve treatment efficiency and reduce costs.
- Develop emergency plans to deal with possible environmental emergencies.
