Embodiment 1

[0036] 1) Prepare the precursor spinning solution: weigh 7ml of absolute ethanol and 3ml of glacial acetic acid in a conical flask as a solvent, then weigh 0.6g of polyvinyl pyrrolidone and add it to the above mixed solution, and stir evenly at room temperature , then slowly add 3.0g of butyl titanate, continue to stir, then weigh 1.2g of diisopropyl azodicarboxylate (foaming agent) and continue to stir, then, add an appropriate amount of WCl 6 , AgNO 3 , ferric chloride, continue to stir for 2h, obtain the precursor spinning solution;

[0037] 2) Electrospinning: put 6ml of the precursor spinning liquid into a plastic needle tube after standing still, and put it on a micro-injection pump, and set the injection speed to 1ml / h. The metal needle is used as the electrospinning anode, and the wire mesh is used as the cathode of the receiving material. The distance between the anode and the cathode is 20cm. Electrospinning is performed at a high voltage of 20kV, and the solid orga...

Abstract

The present application relates to a water filter element with antibacterial effect. The filter element includes a filter element body, an upper end cover sealedly connected to the upper side of the filter element body, and a lower end cover sealedly connected to the lower side of the filter element body. The filter element body includes a central tube and a set The filter material on the outer peripheral side of the central tube, the filter material includes a first filter material layer with the function of filtering impurities, a second filter material layer with the function of filtering organic matter, and a third filter material layer with the function of oil-water separation from the inside to the outside The first filter material layer is arranged around the outer peripheral wall of the central tube and has a wavy star structure in the circumferential direction, and the second filter material layer is arranged around the outer peripheral wall of the first filter material layer and has a multi-layer winding structure, The third filter material layer is arranged around the outer peripheral wall of the second filter material layer and is a multi-layer winding structure; the material of the second filter material layer is a kind of TiO 2 composite fiber, the TiO 2 The composite fiber is specifically TiO 2 / WO 3 / Ag / Fe mesoporous nanofibers.

Description

technical field [0001] The present application relates to the technical field of water filtration, in particular to a water filtration filter element with antibacterial effect. Background technique [0002] Now, water pollution is becoming more and more serious, and the water body contains particulate pollutants, organic pollutants, etc. [0003] In the prior art, the structure of the traditional filter element is generally a single roll-type or origami-type structure, which can only perform the function of filtering impurities or separating oil and water, but the filtering effect on organic matter is not ideal. Contents of the invention [0004] In view of the above technical problems, the present invention aims to provide a water filter element with antibacterial effect to solve the above problems. [0005] An embodiment of the present invention provides a water filter element with antibacterial effect. The filter element includes a filter element body, an upper end cov...
