Embodiment 1
[0029] The preparation method of hydrophilic and oleophobic filter material, comprises the steps:
[0030] 1) Raw material preparation: prepare 90kg fiber silk and 10kg ramie;
[0031] 2) Processing of ramie:
[0032] ① Crush the ramie, add purified water equivalent to twice the weight of the raw material, heat to 60°C for 5 minutes, and obtain a paste-like slurry;
[0033] ②Enzymolysis: adjust the pH of the paste slurry obtained in step ① to be 4, add 0.05% by weight of the paste slurry with an activity of 10,000-30,000 activity units / gram of pectin-cellulose compound enzyme and 0.001% by weight of Mannitol was subjected to enzymolysis for 60 minutes to obtain an enzymolysis solution;
[0034] ③Degreasing: Add 2 times the weight of pure water to the enzymatic hydrolysis solution obtained in step ②, heat to 70°C and extract for 60 minutes to obtain a mixture of the upper layer floating oil liquid and the lower layer liquid and slag;
[0035] ④Drying: drying the lower liquid...
