Problems solved by technology

[0002] Residential water and industrially treated water are usually discharged into the river. After a long time, the water in the river will become black and smelly, and it is very difficult to treat. There are more algae, bacteria, etc. in this black and smelly water. microorganisms, and the existing filter membranes are not ideal for filtering microorganisms such as algae and bacteria. Oxidant resistance performance is particularly important, and because the existing filter membrane adopts a single structure, it is difficult to balance the oxidation resistance performance and membrane flux.

Abstract

The invention discloses a hollow fiber composite biomembrane. The hollow fiber composite biomembrane is in the shape of a tube and sequentially includes an outer layer of a hollow fiber membrane, an outer layer of graphene oxide, a biofilm layer, an inner layer of graphene oxide and a hollow fiber membrane. Fiber membrane inner layer, the section of described biofilm layer is jagged, is provided with plasticizer outer layer between described graphene oxide outer layer and biofilm layer, between described biofilm layer and graphene oxide inner layer Equipped with an inner layer of plasticizer, the hollow fiber composite biomembrane can improve the filtering effect on algae, bacteria and microorganisms, and take into account the membrane flux and oxidation resistance.

Description

technical field [0001] The invention relates to a biofilm, in particular to a hollow fiber composite biofilm. Background technique [0002] Residential water and industrially treated water are usually discharged into the river. After a long time, the water in the river will become black and smelly, and it is very difficult to treat. There are more algae, bacteria, etc. in this black and smelly water. microorganisms, and the existing filter membranes are not ideal for filtering microorganisms such as algae and bacteria. Oxidant resistance performance is particularly important, and because the existing filter membrane adopts a single structure, it is difficult to balance the oxidation resistance performance and membrane flux. Contents of the invention [0003] In order to solve the above-mentioned technical problems, the object of the present invention is to provide a hollow fiber composite biomembrane that can improve the filtration effect on algae, bacteria and microorgan...
