Problems solved by technology

It is preliminarily estimated that the annual output of ginkgo fruit in my country is about 15 million tons, but about 4,000 tons of outer testa are discarded every year, which not only causes a huge waste of this resource, but also leads to serious environmental pollution
Ginkgo biloba polysaccharide is an active polysaccharide obtained from Ginkgo biloba, which has anti-tumor, enhanced immune function in mice, and antioxidant activity, but there is no report on its antibacterial activity

Embodiment 1

[0018] A preparation method for nanometer microspheres for purifying drinking water, comprising the following steps,

[0019] A1: Extract polysaccharides from ginkgo fruit endocarp;

[0020] A2: Compound ginkgo extract with silicon dioxide;

[0021] A3: Compound of polysaccharide / silicon dioxide and nano-microspheres.

Embodiment 2

[0023] A preparation method for nanometer microspheres for purifying drinking water, comprising the following steps,

[0024] A1: Extracting polysaccharides from ginkgo fruit endocarp; extracting polysaccharides from ginkgo fruit endocarp includes the following steps: take ginkgo endocarp, add water, extract at 30-40°C for 2-3 hours and filter, then add 5 times the amount of water to the dregs Extract for 30 minutes, combine the two filtered medicinal solutions, concentrate, add the same volume of petroleum ether as the concentrated medicinal solution to extract twice to degrease, then add savage reagent to remove protein, then put it into a centrifuge, and centrifuge at a high speed of 2000r / min for 5min , remove the insoluble matter, add absolute ethanol to make ethanol, let it stand for 12h, and filter with vacuum pump to obtain polysaccharide.

[0025] A2: Compound the ginkgo extract with silicon dioxide; in step A2, take the ginkgo extract solution and mix it with activat...

Abstract

The invention discloses a preparation method of nano-microspheres for purifying drinking water, comprising the following steps of: A1, preparing willow catkin fibers from willow catkin; A2, esterifying willow catkin fibers; and A3, compounding cellulose and titanium dioxide, and pressing into a honeycomb shape. The microporous antibacterial ball has super-microporosity, and the specific surface area formed by micropores of the ball body is large, so that the inorganic antibacterial agent is distributed in a dispersed state on the outer surface of the whole ball body and inside the ball body toform tens of millions of antibacterial and bacteriostatic contacts; and when the ball body is in contact with water, the water can enter pores inside the ball body from the surface of the ball body.According to the contact antibacterial principle, the larger the contact area is, the better the antibacterial effect is. Through measurement and calculation, antibacterial contacts of the microporousantibacterial ball are increased by nearly ten thousand times compared with those of common silver-loaded antibacterial materials, so that the microporous antibacterial ball has efficient and durableantibacterial performance.

Description

technical field [0001] The invention mainly relates to the technical field of environmental protection, in particular to a method for preparing nanometer microspheres for purifying drinking water. Background technique [0002] Drinking water pollution mainly comes from the random discharge of domestic sewage, industrial wastewater, domestic waste (garbage) or industrial solid waste (waste residue) and neglect of water source sanitation during the process of water intake, water production, water distribution, and water storage. Various reasons such as incomplete protection, water purification and disinfection, poor sanitation management in water distribution and storage, etc., cause pollutants to enter the water, change the physical and chemical characteristics of water quality and the characteristics and composition of biological populations, resulting in deterioration of water quality and harm human health. [0003] Drinking water pollution incidents refer to incidents in ...
