The application discloses a kind of sustainable system processes for removing perfluoro or polyfluoroalkyl substance, belongs to water treatment field.The process is concentrated to foam phase by foam separation in water phase PFAS, combined with nanofiltration membrane system concentration PFAS containing solution, then carries out defluorination degradation by using hydrated electron in electrocatalytic unit;Nanofiltration water is treated by ion exchange resin, saturated resin is backwashed by mixed solution, and backwash waste liquid is regenerated and recycled by another electrocatalytic unit;Finally, harmless calcium fluoride is generated by flocculation and precipitation, and fluoride ion is removed.The process is suitable for various PFAS, can efficiently remove long-chain and short-chain PFAS, total removal rate is high, can cope with complex water quality, is suitable for drinking water, natural water body and industrial wastewater etc.Situations, and no secondary pollution, regeneration liquid can be recycled, realizes sustainable degradation.

A foam separation treatment method is provided that separates organofluorine compounds from treated water by introducing gas into the treated water containing organofluorine compounds and recovering the foam generated. A polymeric surfactant is introduced into the treated water. Therefore, a foam separation treatment method capable of efficiently separating organofluorine compounds from treated water containing organofluorine compounds is provided.

The utility model relates to the technical field of foam and bottom film separation equipment, disclose a kind of foam separating device, including workbench, the workbench outer wall one side is fixedly connected with support frame one, the support frame one inside upside is provided with placement roller, the workbench outer wall other side is provided with collection roller, the workbench upper is provided with separation assembly, the support frame one upper is provided with deviation rectification subassembly, the placement roller outer wall is provided with limiting component, the deviation rectification subassembly includes deviation rectification wheel, the deviation rectification wheel is arranged in support frame one upper. In the utility model, if foam deviates during conveying, electric push rod pushes the sliding of moving block along slide rail, drives deviation rectification subassembly and makes foam homing, then hydraulic rod drives mould to complete separation, and finished product is collected by collection roller, reaches the real-time perception and quick response of foam deviation direction, can automatically and accurately correct foam conveying path, to improve the precision and consistency of foam separation.
