Evaluation of the removal efficiency of perfluorinated compounds in the drinking water treatment process

The research on the removal mechanism and risk control of perfluorinated compounds (PFCs) in drinking water treatment presents complex characteristics of interdisciplinary integration. This paper systematically analyzed the environmental fate behavior of PFCs, revealing the efficiency boundaries and molecular-scale action mechanisms of multi-stage processes such as coagulation - adsorption - membrane separation. It was found that hydrophobic adsorption dominated the removal of long-chain PFCs (Qmax=689 mg/g), while short-chain homologous substances relied more on the bond-breaking degradation of advanced oxidation (k=0.12 min-1). Innovatively proposed a collaborative optimization path for the functional design of MOFs materials and electrocatalytic membrane reactors, combined with artificial intelligence-driven digital twin technology, achieving a 41% reduction in energy consumption with a removal rate of over 97%. The research provides a full-chain solution from molecular mechanisms to engineering applications for the risk management and control of PFCs.
