[0002] Lead-acid battery (VRLA) is a storage battery whose electrodes are mainly made of lead and its oxides, and whose electrolyte is sulfuric acid solution. When the lead-acid battery is in the discharged state, the main component of the positive electrode is lead dioxide, and the main component of the negative electrode is lead; in the charged state, the main components of the positive and negative electrodes are both lead sulfate. High-salt wastewater refers to wastewater with a total salt content of at least 3.5wt%. It mainly comes from chemical plants and the collection and processing of oil and natural gas. This wastewater contains a variety of substances (including salt, oil, organic heavy metals and). Salt-containing wastewater is produced in a wide range of ways, and the amount of water is increasing year by year. It is crucial to remove the impact of organic pollutants in salt-containing wastewater on the environment. When biological methods are used for treatment, high concentrations of salt substances have an inhibitory effect on microorganisms.

A spring (566) is fixedly connected to the port of the stirring frame (563), and an end of the spring (566) is fixedly connected to a stirring plate (567).

6. A method for treating high-salt wastewater for lead-acid battery recovery, characterized in that: The high-salt wastewater purification device for lead-acid battery recycling as claimed in claim 5 comprises the following steps: Step 1: Before purifying the high-salt wastewater for lead-acid battery recycling, heat the high-salt wastewater for lead-acid battery recycling to 50 degrees, place the high-salt wastewater for lead-acid battery recycling in a barrel, and place the barrel filled with the high-salt wastewater for lead-acid battery recycling directly under the water inlet pipe (47). After preparation, connect the water pump (46) to the power supply and turn on the switch of the water pump (46); Step 2: The high-salt wastewater for lead-acid battery recycling enters the inner cavity of the transfer box (42) and enters the inner cavity of the annular evaporation box (31) through the connecting pipe (44). When the height of the high-salt wastewater for lead-acid battery recycling in the inner cavity of the annular evaporation box (31) reaches two-thirds of the short side of the annular evaporation box (31), the switch of the pumping pump (46) is turned off so that the pumping pump (46) no longer pumps the high-salt wastewater for lead-acid battery recycling into the inner cavity of the transfer box (42); Step 3: After the high-salt wastewater for lead-acid battery recovery in the inner cavity of the annular evaporation box (31) reaches a certain height, the operator installs the crystallization device (5) above the annular evaporation box (31), so that the top shell (51) contacts the inner wall of the annular evaporation box (31), and the limiting sleeve (54) is sleeved on the outer surfaces of the first ring (33) and the second ring (35), thereby completing the installation of the device; Step 4: After installing the crystallization device (5), connect the heating motor (37) to the power supply and turn on the switch of the heating motor (37). After the heating motor (37) is powered on, the heating ring (38) generates heat to perform secondary heating on the high-salt wastewater for lead-acid battery recycling until it boils, and the generated water vapor is discharged from the exhaust pipe (53); Step 5: When the water level of the high-salt wastewater for lead-acid battery recycling in the inner cavity of the annular evaporation box (31) reaches one-third of the height of the inner wall of the short side of the annular evaporation box (31), hold the rotating handle (52) and rotate it in a circle. The top shell (51) drives the partition (55) and the collecting device (56) to rotate in the inner cavity of the annular evaporation box (31). During the rotation, the crystallized salt adheres to the outer surface of the precipitation sleeve (565). The stirring plate (567) stirs the residual high-salt wastewater for lead-acid battery recycling in the annular evaporation box (31) to evaporate and crystallize as quickly as possible. After the crystallization is completed, the crystallization device (5) is taken out to collect the salt crystals.
