The invention discloses a method of utilizing a waste leather scrap to prepare a sewage treatment material. The method comprises the following steps: step (1), adding 30-40 parts of water, 50 parts of the waste leather scrap, 10-20 parts of an acrylic acid monomer, 2-5 parts of concentrated sulfuric acid and 0.2-0.5 part of an emulsifying agent by weight to a reaction still, taking a reaction under a stirring condition at 40-50 DEG C for 1-2 hours, and adding 0.5-1 part of a molecular regulating agent while stirring; step (2), raising the temperature to 70-75 DEG C, and taking the reaction for 2-3 hours; step (3), slowly dripping 0.02-0.05 part of an initiator within 2-3 hours, then raising the temperature to 85-90 DEG C, taking the reaction for 0.5-1 hour, cooling to 40 DEG C, utilizing 5 mol / L of a sodium hydroxide solution to regulate the pH value to be 6.5-7.5, and then drying the filtered product to obtain the sewage treatment material. The invention further discloses the sewage treatment material and application thereof.

The invention belongs to the technical field of preparation of functional composite nanofiber membranes and discloses a ZIF-8 / polyvinylidene fluoride composite nanofiber membrane and its preparation method and application. The preparation method of the invention includes the following steps: (1) Mix 2-methylimidazole and polyvinylidene fluoride to obtain a spinning liquid and prepare an electrospinning membrane; (2) Put the electrospinning membrane into methanol of zinc nitrate hexahydrate In the solution, prepare a composite seed crystal membrane with ZIF-8; (3) Then put the composite seed crystal membrane with ZIF-8 into a methanol solution mixed with zinc nitrate hexahydrate and 2-methylimidazole, wash and vacuum After drying, a ZIF‑8 / polyvinylidene fluoride composite nanofiber membrane was obtained. The invention overcomes the problems of low loading rate of ZIF-8 on the fiber membrane surface and serious crystal agglomeration. The adsorption and removal rate of Congo red dye wastewater can reach 92%. The membrane has good regeneration and is convenient for recycling.

The invention discloses a sewage treatment composite material with high adsorption performance. Heavy metal adsorption fibers and organic phosphorus adsorption fibers are compounded and woven according to the mass ratio of 4:1 to form yarn for preparation, then the yarn is woven into filter gauze, and then the filter gauze is fixed on a fixing frame of an MBR assembly to prepare a flat plate filter membrane of the MBR assembly. The filter membrane is prepared by composite spinning of the heavy metal adsorption fibers and the organic phosphorus adsorption fibers; then the filter membrane and aflat membrane in the existing MBR assembly are alternately mounted on the MBR assembly; the filter membrane can adsorb metal ions and can adsorb organic phosphorus compounds, filtration can be achieved, heavy metal ions and organic phosphorus in sewage can be effectively adsorbed, and the problem that an existing MBR technology cannot remove micromolecular heavy metal ions and organic phosphorus is solved.
