Technical Field

[0001] The utility model relates to the technical field of wastewater treatment equipment, and in particular to a photovoltaic fluorine-containing wastewater purification device with a TDS removal function. Background Art

[0002] In recent years, my country's photovoltaic industry has developed rapidly, and photovoltaic wastewater treatment has become increasingly important. Wastewater mainly comes from additive waste liquid and cleaning wastewater generated during the cutting, grinding, slicing of silicon rods and the grinding, corrosion, and polishing of silicon wafers. The main difficulties in its treatment are: high content of organic matter, high content of suspended solids, and pollutants such as fluoride ions and acids and alkalis.

[0003] In the prior art, photovoltaic fluoride-containing wastewater is usually treated by adding a defluoridating agent into the interior of a purification device, and the defluoridating agent combines with the fluoride ions in the wastewater to form a chelate precipitate, thereby achieving the purpose of defluoridating the wastewater; however, the defluoridating agent inside the purification device does not have a sustained effect and cannot be reused; furthermore, the purification device can only remove part of the fluoride ions in the wastewater, and has no purification effect on the TDS in the water body.
