Description

Technical Field

[0001] This utility model belongs to the technical field of titanium dioxide wastewater aeration tanks, and particularly relates to a fully sealed aeration tank for titanium dioxide wastewater. Background Technology

[0002] Titanium dioxide wastewater aeration tanks are primarily used to treat acidic wastewater generated during the titanium dioxide production process. This wastewater typically contains large amounts of H+ and SO42-, as well as metal ions such as Fe2+, Ti3+, Cr2+, and Mg2+ introduced from the mineral powder. It also has a high color value, posing a significant environmental pollution hazard. Aeration treatment can reduce the COD (Chemical Oxygen Demand) content in the wastewater, improve its biodegradability, and create favorable conditions for subsequent treatment.

[0003] However, existing titanium dioxide wastewater aeration tanks are often sealed with fiberglass covers, which has a poor sealing effect. When the liquid level in the aeration tank is high, water is prone to leaking from the sides, and it is not convenient to inspect and maintain the aeration pipes. Utility Model Content
