A novel polysulfone ultrafiltration membrane for wastewater treatment was fabricated using the non-solvent induced phase inversion (NIPS) technique. The modifier was zinc ferrate-reduced graphene oxide (ZnFe2O4-rGO) nanocomposite, which was prepared by sol-gel. The optimum concentration of addiction was found to be 0.1 wt.%, where the hydrophilicity and permeability of the membrane were significantly improved. On this condition, the membrane had a water contact angle of 63.5 and pure water permeance of 517.06 LMH.bar(-1). The membrane resistance was 1.17 * 10(12) m(-1). Moreover, the strength increased by 85.28 cN and the elongation increased by 10.22% with the addition of particles. The results of interception and anti-contamination anal-ysis of three natural organic matters and secondary effluent organic compounds by composite membrane showed that the optimal loading capacity was 0.04 wt.%, and the interception rates of bovine serum albumin, humic acid, and sodium alginate were 95.03%, 73.89%, and 94.50%. After three cycles, the rejection rates were kept 94.50%, 94.72% and 94.87%. The maximum flux recov-ery was 97.92%, 98.15%, and 93.95%. Meanwhile, the irreversible pollution decreased to 19.80%, 19.98%, and 15.98%. In brief, a small amount of ZnFe2O4-rGO NPs can be used to successfully modify the hydrophilicity, permeability, and rigidity cantifouling ability of the membrane.
