Composite active carbon rod filter element and preparation method

Abstract

The invention discloses a composite active carbon rod filter element which is prepared from the following components in percentage by weight: 30 to 50 percent of active carbon powder, 5 to 10 percent of zeolite powder, 5 to 10 percent of a porous carbon nano material, 5 to 10 percent of oxidized graphene, 5 to 15 percent of a pore-forming agent, 30 to 50 percent of a macromolecular adhesive and 0 to 10 percent of antibacterial macromolecules, wherein the macromolecular adhesive is formed by mixing ultra-high molecular weight polyethylene and low-temperature polyethylene according to the weight ratio of (7:3)-(5:5). The invention further discloses a preparation method of the composite active carbon rod filter element. The composite active carbon rod filter element prepared by the preparation method has the advantages of high strength, large flux, powerful function, long life, low cost and the like, and can be repeatedly used after being subjected to simple treatment in the process of applying a sewage treatment station or a large-size water treatment system.

Description

technical field [0001] The invention relates to the technical field of water filtration, in particular to a composite activated carbon rod filter element and a preparation method thereof. Background technique [0002] In the prior art, the multi-stage filter elements of most household water purifiers are configured with PP melt-blown cotton and activated carbon. This configuration has a good effect on intercepting large particles, sediment, rust and adsorbing residual chlorine, but there are also Some defects: [0003] First, the service life of PP melt-blown cotton and activated carbon is inconsistent. When replacing the filter material, the filter bottle needs to be disassembled and assembled many times, which is not only troublesome but also increases the hidden danger of water leakage. [0004] Second, since PP melt-blown cotton and activated carbon filter elements require at least two filter bottles, the overall space area and cost of household filters are increased. ...

AI Technical Summary

Problems solved by technology

[0003] 1. The service life of PP melt-blown cotton and activated carbon is inconsistent. When replacing the filter material, the filter bottle needs to be disassembled and assembled many times, which is not only troublesome but also increases the hidden danger of water leakage.

[0004] Second, since PP melt-blown cotton and activated carbon filter elements require at least two filter bottles, increasing the overall space area and cost of household filters

[0005] Third, most activated carbon filter elements often have insufficient strength, powder loss or black water phenomenon, which affects the quality of effluent water
