The invention discloses a preparation method of a sewage treatment membrane material, which comprises the following steps: 1) preparation of polymerization type bis [3- (triethoxysilyl) propyl ] amine salt, 2) preparation of membrane material, 3) carbon quantum dot grafting membrane material, and 4) ion exchange. The invention also discloses a sewage treatment membrane material prepared by the preparation method of the sewage treatment membrane material. The sewage treatment membrane material disclosed by the invention has good mechanical property, has stronger capabilities of catalyzing the decomposition of organic matters in sewage and adsorbing and separating heavy metal ions in sewage, and is convenient and easy to recover and separate. |
