Porcelain granule produced by using river, lake and sea sludge and shellfish powder as raw materials and preparation method of porcelain granule

Abstract

The invention provides a porcelain granule produced by using river, lake and sea sludge and shellfish powder as raw materials, and a preparation method of the porcelain granule. The porcelain granule is prepared from the following raw materials in parts by weight: 15 to 50 parts of shellfish powder, 5 to 15 parts of kaolin, 1 to 5 parts of grass peat dust,15 to 30 parts of siliceous shale, 15 to 40 parts of furnace slag, 10 to 20 parts of fly ash, 15 to 40 parts of zeolite,10 to 30 parts of the river, lake and sea sludge and 10 to 25 parts of peat, wherein the shellfish powder is crushed to the fineness with the particle diameter being 60 to 200 meshes; the content of silicon dioxide in the siliceous shale is 87.0 to 89.5 percent. The preparation method of the porcelain granule comprises the following steps of taking ingredients; performing crushing, stirring, pelleting, roasting and natural cooling to obtain the porcelain granule. The porcelain granule provided by the invention has the advantages that the sewage treatment effect is good; the porcelain granule is particularly applicable to the heavy metal substance absorption, and is also applicable to building materials; the porcelain granule can absorb harmful substances generated in the building decoration process; the environment pollution problem due to stacking of a great amount of waste shellfish can be solved; the environment is protected.

Description

technical field [0001] The invention belongs to the field of ceramsite, and in particular relates to ceramsite produced by using sludge from rivers, lakes and seas and shellfish powder as raw materials and a preparation method thereof. Background technique [0002] As a light aggregate, ceramsite can replace ordinary sand and gravel to prepare light aggregate concrete. It is widely used in construction, environmental protection, metallurgy, chemical industry, petroleum, agriculture and other departments, especially in water treatment. As a kind of Water treatment packing has been more and more widely used. Adding sludge to fire ceramsite was first proposed by Nakouzi et al. It is made of sludge as raw material, mixed with appropriate amount of auxiliary materials, and formed into balls and roasted. [0003] Shells, oysters, etc. are common marine or river and lake seafood. Currently, the development and utilization of shell products is generally to process their edible part...

AI Technical Summary

Problems solved by technology

The ceramsite has a good sewage treatment effect, especially suitable for the adsorption of heavy metal substances; it is also suitable for building materials, and can absorb harmful substances produced in the process of building decoration; it can also solve the environmental pollution caused by a large number of discarded shells. surroundings
