Organic-inorganic compound water treatment ceramic particle and preparation technology thereof

Abstract

The invention provides an organic-inorganic compound water treatment ceramic particle and a preparation technology thereof. The technology comprises the following steps of weighing water and sodium polyepoxysuccinate solid powder according to the weight proportion of 5 to 1, heating the water to 80 to 100 DEG C, then adding the sodium polyepoxysuccinate solid powder into the water, stirring for 20 to 30 minutes in the temperature of 80 to 100 DEG C and then putting in a room temperature to obtain polyepoxy sodium succinate water solution; pouring a porous water treatment ceramic particle into a volumetric barrel, weighing the polyepoxy sodium succinate water solution according to 1.5 times of the natural accumulation volume of the ceramic particle, pouring the polyepoxy sodium succinate water solution into the volumetric barrel, sealing and standing for 72 hours; taking the soaked porous water treatment ceramic particle out, arranging the ceramic particle into an oven, adjusting a temperature to 115 to 120 DEG C and drying to the constant weight to obtain the organic-inorganic compound water treatment ceramic particle. The technology can improve the adsorption and degradation ability of the water treatment ceramic particle.

Description

【Technical field】 [0001] The invention relates to the field of environmental materials, in particular to an organic-inorganic composite water treatment ceramsite and a preparation process thereof. 【Background technique】 [0002] Biological aerated filter is a new type of biological pretreatment technology developed in Europe and the United States in the 1980s. The core of its technology is the filter medium, that is, the filter material. As a carrier of microorganisms, it directly affects the growth, reproduction and shedding of microorganisms. The process affects the effect of water treatment. The requirements for the performance of the filter material are large specific surface area and large amount of fixed microorganisms; good biological affinity, fast microbial film formation, and easy fall off of aging biofilm; high stability, acid and alkali resistance, oxidation resistance, etc.; ceramsite as a A new type of filter material, its function is that the ceramsite has a ...

AI Technical Summary

Problems solved by technology

Compared with the most widely used activated carbon at present, ceramsite has the characteristics of higher strength, not easy to break, long service life and low cost, but its disadvantage is that the specific surface area is relatively small, and the internal surface area of ​​its micropores is also significantly smaller than activated carbon. In terms of the adsorption effect of organic matter, the effect of ceramsite is obviously inferior to that of activated carbon.
