Problems solved by technology

[0003] At present, all kinds of porous ceramic filter elements for water purification on the market are mostly fired from cohesive soil such as diatomaceous earth. Using their natural pore structure, bacteria and macromolecular organic matter can be removed, but they are not effective for removing arsenic, lead, cadmium, etc. Heavy metal ions are not effective and cannot purify water well
In addition, all kinds of water purification filter elements only play a simple filtering role, and the filtered water does not achieve the effect of mineral filtration

Embodiment 1

[0027] The preparation method of the zeolite molecular sieve composite rectorite water purification ceramic based on geological materials provided in this example is as follows: 40 parts of modified rectorite, 33 parts of modified kaolin, 10-40 parts of talc, α-Al 2 o 3 8 parts, 4 parts of pottery clay, 8 parts of lapis lazuli, and 20 parts of pore-forming agent are evenly mixed in proportion, then add 1 part of diluent and 400 g of deionized water, and the mass of each part is 10 g. Stir with a magnetic stirrer, stir evenly and place After half an hour, the mud is prepared; the fluid mud is injected into the plaster mold, so that the mud adheres to the model in a dispersed manner, forming a mud layer with the same shape as the model, and gradually thickens as time goes on. When the thickness is certain, turn the mold upside down, pour out the slurry, let it stand for 0.5 to 1 hour, remove the filter element body from the plaster mold to obtain a composite ceramic filter eleme...

Embodiment 2

[0031] The preparation method of the zeolite molecular sieve composite rectorite water purification ceramic based on geological materials provided in this example is as follows: 46 parts of modified rectorite, 27 parts of modified kaolin, 18 parts of talc, α-Al 2 o 39 parts, 5 parts of pottery clay, 14 parts of lapis lazuli and 20 parts of pore-forming agent are uniformly mixed in proportion, then add 1 part of diluent and 400 g of deionized water, the mass of each part is 10 g, stir with a magnetic stirrer, and stir evenly Place it for half an hour to make mud; inject the fluid mud into the plaster mold, make the mud adhere to the model in a dispersed manner, form a mud layer with the same shape as the model, and gradually thicken as time goes by, when When it reaches a certain thickness, turn the mold upside down, pour out the slurry, and let it stand for 0.5 to 1 hour, then remove the filter element body from the plaster mold to obtain a composite ceramic filter element gre...

Embodiment 3

[0034] The preparation method of the zeolite molecular sieve composite rectorite water purification ceramic based on geological materials provided in this example is as follows: 50 parts of modified rectorite, 40 parts of modified kaolin, 35 parts of talc, α-Al 2 o 3 10 parts, 7 parts of pottery clay, 120 parts of lapis lazuli and 30 parts of pore-forming agent are uniformly mixed in proportion, then add 2 parts of diluent and 300 g of deionized water, the mass of each part is 5 g, stir with a magnetic stirrer, and stir evenly Place it for half an hour to make mud; inject the fluid mud into the plaster mold, make the mud adhere to the model in a dispersed manner, form a mud layer with the same shape as the model, and gradually thicken as time goes by. When it reaches a certain thickness, turn the mold upside down, pour out the slurry, and let it stand for 0.5 to 1 hour, then remove the filter element body from the plaster mold to obtain a composite ceramic filter element green...

Abstract

The invention provides a geomaterial-based zeolite molecular sieve composite rectorite water purification ceramic which is composed of a main material and an auxiliary material, wherein the particle sizes of the main material and auxiliary material are respectively 220-1200 meshes. The main material is composed of the following components in parts by mass: 40-80 parts of modified rectorite, 12-60 parts of zeolite and 25-50 parts of modified kaolin. The auxiliary material is composed of the following components in parts by mass: 10-40 parts of talcum, 8-10 parts of alpha-Al2O3, 4-8 parts of argil, 8-15 parts of celestite, 15-30 parts of pore forming agent and 1-3 parts of diluter. The invention also provides a preparation method of the geomaterial-based zeolite molecular sieve composite rectorite water purification ceramic. The filter element prepared by the method can remove heavy metals, TN (total nitrogen), TP (total phosphorus), bacteria and other pollutants in the water body by utilizing the molecular sieving effect and cation exchange, and meanwhile, release specific elements which are beneficial to the human body.

Description

technical field [0001] The invention belongs to the field of preparation of porous ceramic filter materials, and in particular relates to a geological material-based zeolite molecular sieve composite rectorite water purification ceramic material and a manufacturing method thereof, which are used to solve the problem of drinking water treatment. Background technique [0002] With the rapid development of industry and the vigorous development of mining, the water quality of most surface water sources in the country is deteriorating. Water is the main carrier for the transmission of various germs, and 80% of human diseases are related to water pollution. At present, surface water sources and groundwater in some areas are polluted to varying degrees, and the problem of water shortage has aroused widespread concern. Drinking water source pollutants are mainly composed of heavy metal ions (such as mercury, lead and cadmium, etc.), bacteria and viruses (such as Escherichia coli), ...
