Embodiment Construction

[0029] The present invention will be further described below in conjunction with the accompanying drawings.

[0030] The preparation method of the antibacterial type graphene modified activated carbon filter material for water purification, the specific steps are as follows:

[0031] Step 1, take raw material: according to mass ratio, binding agent: graphene: active carbon=0.4:1:300 take raw material for subsequent use; This selection binding agent is chitosan; The sheet diameter of graphene is 1 μ m, thickness 1nm; activated carbon is wood charcoal. Wherein: according to mass ratio, binder: graphene: activated carbon=(0.05~0.5):1:(100~400) all can. The binder is chitosan, pullulan, soluble α-starch binder, hydroxypropyl starch, phosphate starch, hydroxypropyl starch ether, sodium carboxymethyl starch, microcrystalline cellulose, carboxymethyl Any one or more of cellulose sodium, carboxymethyl cellulose calcium, sodium hexametaphosphate, sodium alginate, paraffin, purified k...

Abstract

The invention provides a preparation method of an antibacterial graphene-modified activated carbon filter material that can be used for water purification. The application of graphene to the activated carbon filter material for water purification can improve the antibacterial problem of the activated carbon; Antibacterial graphene-modified activated carbon has more capillary structures, which can prolong the water flow and fully absorb impurities such as tiny particles, heavy metals and microorganisms in the water, making the effluent more pure, and improving the traditional activated carbon. The problem of insufficient water filtration.

Description

technical field [0001] The invention relates to a filter material for water treatment, in particular to a filter material for direct drinking water, and provides a graphene-containing activated carbon filter material with antibacterial properties for direct drinking water filtration and a preparation method thereof. Background technique [0002] Direct drinking water, also known as healthy running water, refers to water that can be directly drunk without pollution, without degradation, in line with the physiological needs of the human body (containing beneficial mineral elements similar to the human body), and with a weakly alkaline pH value. At present, direct drinking water technology mainly uses iodine catalase technology and separation membrane device to filter, kill viruses and bacteria, so as to remove different colors, odors, residual chlorine, ozone hydrogen sulfide, bacteria, viruses, heavy metals in tap water, and block suspension. Granules improve water quality wh...
