Preparation method of multifunctional nanofiber water purification membrane

Abstract

The invention provides a preparation method of a multifunctional nanofiber water purification membrane, which comprises the following steps: fully mixing a polymer solution with an organic solvent, and then dividing into three parts of mixed solutions with the same amount; taking one part of the mixed solution, adding a silver nitrate solution and nano-iron particles, and emulsifying to obtain an emulsion; putting 1 / 10 parts by mass of the mixed solution into a glass cup, putting 2 / 10 parts by mass of the emulsified liquid into a glass cup filled with the mixed solution, fully stirring to fully mix the mixed solution and the emulsified liquid to obtain a stirred solution, and equally dividing the stirred solution into two parts; injecting the two groups of mixed solutions, the two groups of stirred solutions and the emulsion into a spinning electrode in sequence, and spinning the multifunctional nanofiber water purification membrane through an electrostatic spinning machine; 4, the multifunctional nanofiber water purification membrane obtained in the step 4 is put into a constant-temperature box to be subjected to warm screening treatment, water can be continuously and stably sterilized and disinfected, heavy metal ions in the water can be removed, and the service life is long.

Description

technical field [0001] The invention relates to the field of water purification membranes, in particular to a preparation method of a multifunctional nanofiber water purification membrane. Background technique [0002] Water is the source of life and the material basis for social and economic development and social progress. Although my country's land area ranks third in the world, my country's water resources are still very scarce, and it is one of the thirteen most water-scarce countries in the world. Therefore, we should recycle water resources more, so some purification devices are needed to purify water resources. [0003] At present, the main method of water purification is to filter and purify water through the purification membrane layer, but the bactericide in the current water purification membrane is unevenly distributed on the purification membrane, and the bactericide is easy to fall off from the water purification membrane, resulting in The purification membr...

Problems solved by technology

[0003] At present, the main method of water purification is to filter and purify water through the purification membrane layer, but the bactericide in the current water purification membrane is unevenly distributed on the purification membrane, and the bactericide is easy to fall off from the water purification membrane, resulting in The purification membrane cannot continuously and stably remove bacteria and viruses in the water. At the same time, water purification also needs to deal with heavy metal ions in the water. The current water purification needs to add a purification membrane with the function of removing heavy metals, and the water purification membrane has the function of filtering. It has fine fibers, so it is easy to cause damage to the water purification membrane when cleaning the water purification membrane, which will seriously affect the use effect and service life of the water purification membrane
