▎ 摘　　要

NOVELTY - Method for preparing hollow fiber braided tube filter membrane, involves using hollow fiber braided tube as supporting base material, sequentially fixing photothermal conversion functional material and hydrophobic polymer on outer surface of hollow fiber braided tube using traction immersion modification technology, and preparing hollow fiber braided tube filter membrane. USE - Method for preparing hollow fiber braided tube filter membrane used for waste water reduction in polluted seawater, pharmaceutical waste water, organic solvent evaporation, chemical waste water, reverse osmosis concentrated waste water, garbage permeate waste water or sludge reduction and extrusion concentrated waste water (all claimed). ADVANTAGE - The hollow fiber braided tube filter membrane has loose hydrophilic network structure and hydrophobic external structure, the hydrophilic network is conducive to the transport of water molecules, and the outer hydrophobic layer is conducive to water vapor escape and salt/fouling resistance, extrudes the sludge reduction from concentrated wastewater and other complex and difficult to purify sewage, and achieves all-weather membrane evaporation reduction and zero discharge in natural environment. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a hollow fiber braided tube filter membrane prepared using above-mentioned method, where the evaporation efficiency of membrane module made is 3.5-4 kg/(m2.hour)
