Abstract

The invention discloses an anti-microbial contamination hollow fiber membrane and a preparation method thereof, belongs to the technical field of membranes, and particularly relates to an anti-contamination polymeric membrane technique. The anti-microbial contamination hollow fiber membrane contains carbon nanotubes; and the mass ratio of polyvinylidene fluorid (PVDF) to carbon nanotubes is 1:0.001 to 1:0.01. Compared with the conventional PVDF hollow fiber separation membrane preparation, the product disclosed by the invention can be produced without special equipment and the industrial implementation is easy; in a word, the process is simple and the increase in the cost of the membrane is low. The hollow fiber separation membrane product has high attachment inhibition effect on microbesin separation media, and has high microbial contamination resistance.

Description

A kind of anti-microbial pollution hollow fiber membrane and preparation method thereof technical field The invention belongs to the field of membrane technology, in particular to a pollution-resistant polymer membrane technology. Background technique Membrane fouling refers to the adsorption and deposition of particles, colloidal particles or solute macromolecules in the separation medium on the membrane surface or in the membrane pores due to the physical and chemical interaction or mechanical interaction with the membrane during the membrane separation process, causing the membrane pore size to become smaller or Clogging causes the membrane to produce irreversible changes in permeation flow and separation characteristics. For membrane fouling, membrane fouling begins once the separation medium feed liquid comes into contact with the membrane. There are many types and causes of membrane fouling, among which microbial fouling of separation membranes has attracted much a...
