A method for preparing a homogeneous tubular braid-reinforced poly(p-phenylene terephthalamide) (PPTA) hollow fiber membrane, which combines PPTA hollow tubular braids with a PPTA surface separation layer, wherein the method comprises the following steps of: preparing PPTA hollow tubular braids, wherein: the PPTA hollow tubular braids which are made from PPTA filament yarns are woven by a two-dimensional braided method, and they are served as a reinforced matrix for HMR PPTA hollow fiber membranes, wherein an outer diameter of the PPTA tubular braids is 1-2mm; a filament yarn denier is 50-800D; a woven pitch is 5-20mm; providing surface pre-treatment of the PPTA hollow tubular braids, wherein: surfaces of the hollow PPTA tubular braids are immersed in a surfactant for 2-3h prior to a membrane preparation, and then repeatedly flushed with clean water and totally dried for further use, wherein the surfactant is sodium dodecylsulphate or sodium dodecylsulfate; preparing a PPTA casting solution as the surface separation layer, wherein: the pre-treated PPTA resin, pore-forming agents and inorganic particles are mixed into an inorganic acid solvent, stirred for 1-3 hours at 70°C-90°C to form a homogeneous and transparent casting solution, wherein the components of the casting solution and a mass fraction of surface separation layer are: the PPTA resin 1-3wt% the pore-forming agents 10-20wt% the inorganic particles 0-2wt% the inorganic acid solvent 75-89wt%, totally 100%; wherein a logarithmic specific concentration viscosity of the PPTA resin is 4-10dL/g; wherein the pore-forming agents are water-soluble macromolecules, which is selected from polyethylene glycol with an average molecular weight of 600-20000, or polyvinylpyrrolidone with an average molecular weight of 10000-100000, or a mixture of the PEG and the PVP with a ratio of (4:1)-(10:1) by weight; wherein the inorganic particles are selected from a group consisting of silicon dioxide, titanium dioxide and graphene oxide; wherein the inorganic acid solvent is concentrated sulfuric acid with a mass concentration at a range of 98-106wt%; and preparing the reinforced PPTA hollow fiber membrane, wherein: the casting solution as the surface separation layer is evenly coated on the surfaces of the PPTA hollow tubular braids through a spinneret, and then they are passed through an air bath of 1-10cm under the winding tension, afterwards they are immersed in a coagulation bath at 0-50°C for solidified formation, so as to obtain the as-spun HMR PPTA hollow fiber membranes, wherein a spinning temperature is kept at 60-80°C, a speed of winding tension is 1-30m/h, the coagulation bath is a sulfuric acid solution with a mass fraction of 0-30%. preparing PPTA hollow tubular braids, wherein: the PPTA hollow tubular braids which are made from PPTA filament yarns are woven by a two-dimensional braided method, and they are served as a reinforced matrix for HMR PPTA hollow fiber membranes, wherein an outer diameter of the PPTA tubular braids is 1-2mm;
