Method for reinforced ultrafiltration treatment of phenol-containing waste-water by ultrafiltration membrane

The invention discloses a method for ultra-filtration membrane strengthened ultra-filtration treatment of phenol-containing sewage. The method comprises: first adding cetylpyridinium chloride which is a cationic surfactant, and sodium carbonate into the phenol-containing sewage, stirring uniformly and standing for reaction where cetylpyridinium chloride monomer molecules produce micelles by self-assembly and then solubilize the phenol contained in the water; pumping the water to an ultra-filtration component for filtration where the cetylpyridinium chloride micelles with being solubilized the phenol contained in the water are intercepted by the ultra-filtration membrane so that the phenol contained in the water is removed. The phenol concentration in the sewage is 5mg/L-200mg/L; the addition of cetylpyridinium chloride is 20*10mol/L-30*10mol/L; the addition of sodium carbonate is 1*10mol/L-20*10mol/L; the weight of molecules intercepted by the ultra-filtration membrane is 6000-10000Dalton; the
