AI Technical Summary
In existing technologies, the washing wastewater generated during FEP production fails to effectively demulsify, resulting in the inability to reuse the wastewater, which in turn leads to waste of water resources and demulsified materials, and consequently causes environmental pollution.
A novel wastewater treatment method for washing processes is adopted, which combines an initial aeration tank and an air flotation tank with physical and mechanical methods to break up the emulsion. The multiple collisions in the aeration and air flotation tanks cause the emulsion particles to aggregate. Combined with defluorination treatment, the wastewater is ultimately reused.
It achieves effective demulsification of FEP washing wastewater and recovery of demulsified material, realizing the secondary utilization of wastewater and the resource utilization of pollutants, and reducing pollutant emissions.
