The invention discloses a preparation method of a polyphenylene sulfide membrane capable of resisting microbial pollution. The preparation method comprises the steps of mixing polyphenylene sulfide, nano-silver and other materials, carrying out supercritical CO2 assisted extrusion, casting to form a primary membrane, and carrying out two-way stretching on the primary membrane to form a gas-permeable membrane; and grafting octyl isothiazolinone to the gas-permeable membrane plasma to obtain the polyphenylene sulfide membrane capable of resisting microbial pollution. According to the preparationmethod disclosed by the invention, the processing fluidity of polyphenylene sulfide is improved, the processing temperature of polyphenylene sulfide is reduced, the porosity of the polyphenylene sulfide membrane is improved, the density of antibacterial groups is high, the utilization efficiency of an antibacterial agent is high, and the durability of an antibacterial effect is good. 本发明公开一种抗微生物污染的聚苯硫醚膜的制备方法，将聚苯硫醚、纳米银等物料
