The invention discloses a method for recovery treatment of a waste-and-old lithium battery electrolyte and treatment of electrolyte wastewater. Three treatment units are employed for treatment. Firstly, the waste-and-old electrolyte is treated. Then, waste gas resulting from the reaction of the electrolyte is pumped into the waste water for absorption, so that the waste gas can be removed during a waste water treatment process; the lithium battery waste water is treated by a Fenton agent through oxidation to obtain improved biodegradability of the waste water; and reaction precipitates are removed through flocculent sedimentation and the obtained water is treated through combination of A2 / O and MBR membrane separation. Finally, the outlet water goes through a RO reverse osmosis unit to ensure the quality of the outlet water. Combination technology of active carbon powder adsorption and ultra-filtration is employed to remove organic pollutants of the concentrated water resulting from the RO unit, so that the water after treatment can meet the requirements of RO high-quality reuse water. According to the invention, imperfection of an existing technical method of waste-and-old lithium battery recovery and treatment is overcome, and quantitative reduction, harmlessness, and reutilization of waste water treatment of the waste-and-old electrolyte are realized.
