Abstract

The invention discloses a biomimetic photocatalysis membrane separation assembly for purifying water, belonging to the technical field of membrane separation, photocatalysis materials and water treatment. The invention aims at simulating plant leaf blades and plant morphology, preparing a photocatalysis separation membrane, enabling a membrane assembly to reasonably utilize space, have flexible structure and to be disturbed easily by a water flow and an airflow, reducing precipitation of pollutants on a membrane surface, fully utilizing light and improving the light use rate. The biomimetic photocatalysis membrane separation assembly is characterized in that the biomimetic membrane piece is prepared by utilizing the fractal characteristic of the plant leaf blade, and a biomimetic membraneassembly is assembled by utilizing the branch structures of trees and a biomimetic principle to assembly the bionic membrane and improve light use rate of the assembly; and the flexible structure of the membrane assembly is beneficial to reducing pollutant precipitation by using a disturbance effect of the water flow and the airflow so as to prevent the inactivation of a catalyst. The invention has the advantage of providing a preparation method of the novel biomimetic photocatalysis membrane separation assembly and a method for separating the pollutants in water by utilizing the high-efficiency photocatalysis membrane of the membrane assembly. The invention can be widely applied to photocatalysis to remove pollutants and purify water.

Description

technical field

[0001] The invention belongs to the fields of photocatalytic materials and water treatment and purification. It involves the use of bionic principles to make membranes containing photocatalysts into new catalytic separation composite membranes and water purification membrane components with bionic characteristics of leaves, plant shapes and structures. Specifically, it involves using the shape of the leaves and plants as the design principle of the membrane module, so that the membrane module has a reasonable spatial layout. On the one hand, it has the characteristics of efficient use of light energy, and on the other hand, it can use the disturbance of water flow to reduce the pollutants in the water. Membrane surface deposition fouling characteristics. The membrane separation function of this module is combined with the photocatalytic function, which has a double water purification function.
