Wastewater Treatment and Reuse System for Lithium Battery Cathode and Anode Material Production Lines – Jiangsu Weilan

Treatment scope:

1. Rinse wastewater from anode production: main raw materials are graphite and silicon oxide (SiO).
2. Wastewater from cathode production: raw materials include lithium nickel cobalt manganese oxide, a small amount of NMP, electrolyte and lithium iron phosphate.
3. Wastewater from pre-lithiation: raw materials include LiOH, a trace amount of Li₂CO₃, graphite and silicon (Si).
4. Laboratory glassware rinse wastewater: alkaline mixed wastewater generated when cleaning equipment after experiments with lithium nickel cobalt manganese oxide, graphite, silicon oxide and other materials. Residual waste solution in the lab equipment is handled as hazardous waste.
