Microporous ceramic used for processing sewage

Abstract

The invention discloses a microporous ceramic used for processing sewage. The microporous ceramic comprises the following raw materials in parts by weight: 30-42 parts of dimethyl sulfoxide, 5-10 parts of magnesium oxide, 10-18 parts of trichloromethane, 5-10 parts of iron oxide, 11-15 parts of cerium acetylacetonate, 1-4 parts of antimony oxide, 10-22 parts of silicon nitride, 2-5 parts of barium carbonate, 3-10 parts of magnesite, 5-8 parts of dimethylaniline, 20-30 parts of porcelain stone, 1-8 parts of quartz powder, 2-5 parts of allophone, 5-10 parts of aluminum acetylacetonate, 1.5-2.5 parts of polycarbosilane, 2-5 parts of cresol, and 3-5 parts of wollastonite. The microporous ceramic selects a plurality of raw materials with reasonable ratio, the size of the aperture can be controlled in a small scope, the finally produced microporous ceramic has stable and efficient filtering capability. The raw material configuration can uniformly distribute heat during a ceramic sintering process, so that the aperture distribution on the ceramic is more uniform, and the filtering capability stability can be guaranteed.

Description

technical field [0001] The invention belongs to the technical field of ceramic material preparation, and in particular relates to a microporous ceramic that can be used for sewage treatment. Background technique [0002] At present, environmental protection has become an important subject for human beings, and the protection of water resources is the top priority. Although 70.8% of the earth is covered by water, fresh water resources are extremely limited. What humans can really use are rivers, lakes and a part of groundwater, which only account for 0.26% of the total water on the earth, and the distribution is uneven. [0003] After the 1950s, the global population increased rapidly, the industry developed rapidly, the global water resource situation deteriorated rapidly, and the "water crisis" became increasingly serious. On the one hand, the human demand for water resources is expanding at an alarming rate; on the other hand, the increasingly serious water pollution has ...

AI Technical Summary

Problems solved by technology

However, the existing microporous ceramics are not ideal for the application in the field of sewage treatment.

Because the existing microporous ceramics generally have uneven pore sizes, and their pore sizes are often distributed between millimeters and microns. Because the existing microporous ceramic preparation methods are difficult to control the final ceramic pore size, so Its filtering ability is also difficult to be guaranteed

At the same time, due to the different selection of raw materials, the pores of microporous ceramics often have uneven distribution density, which also severely limits their filtration capacity.
