[0026] Principle of wastewater purification device for lithium battery disassembly

[0027] The working principle of the wastewater purification device for lithium battery disassembly is mainly based on the following treatment technologies:

[0028] Physical treatment:

[0029] Through sedimentation, filtration and other methods to remove suspended solids and large particle impurities in wastewater. The sedimentation tank uses gravity to precipitate suspended solids, while the filter removes solid particles through the interception of filter material.

[0030] Activated carbon layer adsorption: using the adsorption performance of activated carbon to remove organic pollutants and part of heavy metal ions in wastewater. The highly developed pore structure of activated carbon makes it have strong adsorption capacity.

[0031] Chemical treatment:

[0032] Neutralization: Adjust the pH of the wastewater by adding acid-base neutralizers to meet the discharge standards.

[0033] Chemical precipitation: Add chemical reagents (such as lye, precipitants) to the wastewater to precipitate heavy metal ions in the form of insoluble compounds, and then remove these solid substances through precipitation or filtration.

[0034] Redox: Use oxidizing or reducing agents to convert organic matter or heavy metal ions in wastewater into harmless substances.

[0035] Biological treatment:

[0036] Utilize the metabolic action of microorganisms to remove organic matter and part of heavy metal ions in wastewater. Common biological treatment processes include activated sludge method, biofilm method, etc.

[0037] In the activated sludge method, wastewater is in full contact with microorganisms in activated sludge, and organic matter is degraded by microorganisms; in the biofilm method, wastewater is in contact with biofilm fixed on the surface of the carrier, and the biofilm adsorbs and degrades pollutants.

[0038] Membrane separation technology:

[0039] Utilize the selective permeability of membranes to separate and concentrate pollutants in wastewater. Common membrane technologies include ultrafiltration membranes, nanofiltration membranes, and reverse osmosis membranes.

[0040] Ultrafiltration membranes are used to remove large molecular organic matter and suspended solids; nanofiltration membranes are suitable for removing part of dissolved organic matter and low molecular weight heavy metals; reverse osmosis membranes are used for deep purification of wastewater, which can effectively remove small molecular organic matter, heavy metal ions and dissolved salts.

[0041] Advanced oxidation treatment:

[0042] Use oxidizing agents combined with catalysts to efficiently degrade organic pollutants in wastewater. Common advanced oxidation technologies include Fenton oxidation, ozone oxidation, and photocatalytic oxidation, etc.

[0043] These methods generate strong oxidizing substances (such as hydroxyl radicals, ozone, etc.) to degrade organic matter into harmless small molecular substances.

[0044] In summary, the wastewater purification device for lithium battery disassembly uses a combination of physical, chemical, biological and membrane separation technologies to effectively remove pollutants in wastewater and achieve standard discharge or resource utilization.
