[0002] The basic principle of membrane technology for treating wastewater is to utilize the penetrability of water molecules in aqueous solution (raw water). Through specific membrane materials, water molecules are allowed to penetrate the membrane layer under the action of external forces (such as pressure difference), while solutes or other impurities are retained on one side of the membrane, thereby achieving the purpose of separation and purification. This technology belongs to the category of physical separation. No phase change occurs when the substance passes through the membrane, and the separation efficiency is high. It is energy-saving, easy to operate, and can be automated.

[0003] The electrolyte wastewater recovered from lithium batteries is characterized by large production volume and high solute content. The device for treating the wastewater with a membrane in the existing technology filters the electrolyte wastewater through a membrane. The membrane can continue to be used after the electrolyte is filtered, but the impurities filtered out during the filtration of the electrolyte wastewater will adhere to the surface of the membrane. The impurities on the top of the membrane need to be manually cleaned with a machine. Manual cleaning of impurities will seriously affect the wastewater treatment efficiency, resulting in low treatment efficiency of the electrolyte wastewater recovered from lithium batteries.
