TL;DR: In this article, a composite membrane preparing technology of coating a layer of compact bacterial fiber membrane on a paper porous basement membrane is proposed, which consists of the following steps that: vegetable fibers are prepared into the porous paper basement membrane by utilizing a papermaking process; uniformlydispersed bacterial fibers are coated on the paper porous bottom membrane through composite papermaking or coating to form a layer; and the membrane layer is dried at the high temperature to obtain a micro-filtration membrane of which the average pore size is between 0.01 and 10 microns.
