Technical Field

[0001] The utility model relates to the technical field of titanium dioxide processing, in particular to a wastewater treatment device for titanium dioxide processing. Background Art

[0002] Titanium dioxide is an important inorganic chemical raw material and plays a vital role in industry. The production of titanium dioxide generates significant pollution, leading to increasing attention to wastewater treatment methods. Currently, titanium dioxide production primarily utilizes the sulfuric acid process. In addition to waste sulfuric acid at a concentration of 20%, titanium dioxide also generates significant amounts of acidic wastewater (primarily from the washing and exhaust gas scrubbing stages). This acidic wastewater contains free sulfuric acid, ferrous sulfate, metatitanic acid, and other metal ion sulfates.

[0003] Usually, a large amount of wastewater is generated during the production of titanium dioxide, and the wastewater needs to be treated before it can be discharged. Generally, the wastewater is first filtered to intercept impurities in the wastewater. However, after a period of filtration, impurities are easily adsorbed on the filter membrane, causing the filter membrane to be blocked, resulting in a decrease in water output; therefore, we proposed a wastewater treatment device for titanium dioxide processing to solve the above problems.
