Problems solved by technology

However, although the above-mentioned advanced wastewater treatment method can reduce the number of bacteria in the water body, the equipment used in the above-mentioned method is expensive and the operation is relatively cumbersome, which is not suitable for water supply terminal-home use, thus limiting the application space of the above-mentioned method
[0006] Prior art also has the antibacterial agent etc. that adopt silver system, but the price of silver is comparatively expensive
More importantly, it is not resistant to water erosion, and the silver dissolution rate is high, which easily causes secondary pollution of silver.
In addition, its antibacterial rate also needs to be improved

preparation example Construction

[0019] The invention provides a kind of preparation method of antibacterial agent, comprising:

[0020] The 13×zeolite molecular sieve is placed in the copper ion solution to obtain the copper ion-loaded molecular sieve.

[0021] Molecular sieve is a crystalline aluminosilicate, which has the structure and characteristics of a crystal. The surface is a solid skeleton, and the internal pores can play the role of adsorbing molecules. The pores are connected with each other by channels, and the molecules pass through them. Molecular sieve powder has a strong polarity and Coulomb field inside the crystal pores through the physical adsorption of the van der Waals force of the substance, and shows a strong adsorption capacity for polar molecules and unsaturated molecules. Moreover, the pore size distribution of the molecular sieve is very uniform, and only substances with a molecular diameter smaller than the pore diameter can enter the crystal cavity of the molecular sieve. The p...

Embodiment 1

[0040] Take the molecular sieve with a particle size of 100 mesh to 120 mesh and the molecular sieve with a particle size of 60 mesh to 100 mesh with a weight ratio of 6.5:1, place the above molecular sieve in a copper sulfate solution with a concentration of 0.5mol / L for 3 days, and then centrifuge. The molecular sieve is washed with deionized water until there is no copper ion in the washing liquid, and then dried to obtain the copper-supported molecular sieve.

Embodiment 2

[0042] 13 × zeolite molecular sieve is mixed with NaF and EDTA, dried, the addition of NaF is 1% of the mass of 13 × zeolite molecular sieve; the addition of EDTA is 4% of the mass of 13 × zeolite molecular sieve to obtain the modified 13 × zeolite molecular sieve.

[0043] Take the above-mentioned modified 13×zeolite molecular sieve of 60 mesh to 100 mesh, put it in a copper sulfate solution with a concentration of 0.4mol / L for 2 days, and then centrifuge it, and soak and wash the molecular sieve in a 0.1mol / L sodium silicate aqueous solution until Dry the washing solution without copper ions to obtain the copper-loaded molecular sieve.

Abstract

The invention provides a preparation method of a bacteriostatic agent. 13* zeolite molecular sieves are added into a copper ion solution to obtain copper-ion-loaded molecular sieves. The copper ions can inhibit the bacteria. Moreover, the molecular sieve can absorb organic substances as a carrier, and the bacteria can be attracted by the organic substances, so the bacteria can be aggregated around the bacteriostatic agent, and thus the bacterium inhibiting effect of the copper ions is further enhanced. So the bacteriostatic agent prepared by the provided preparation method has an excellent bacterium inhibiting effect. Furthermore, the application of the bacteriostatic agent is very easy namely contacting the bacteriostatic agent with a water body to be processed. The bacteriostatic agent can be placed into a filter cylinder, or can be placed before a micro-filter membrane or UF membrane. The bacteriostatic agent will not generate secondary pollution easily.

Description

technical field [0001] The invention relates to the field of water treatment, in particular to a bacteriostatic agent, a preparation method thereof and a water purification device. Background technique [0002] In recent years, with the rapid development of industry, more and more industrial waste water has been discharged into rivers and lakes, my country's water resources have been destroyed, the quality of groundwater has deteriorated, and many substances harmful to human body have been produced in the water. The severity of water pollution poses a serious threat to the safety of drinking water, and the treatment of water pollution, especially the treatment of sewage, has attracted more and more attention. [0003] The drinking water sources in many cities and towns in my country are slightly polluted water, and there will still be some biodegradable organic matter in the water body after conventional treatment by the water plant, which provides nutrients for the growth a...
