Embodiment 1

[0037] Embodiment 1: a kind of rare earth ceramsite, main material comprises kaolin and potassium feldspar; Auxiliary material comprises pore-forming agent and bonding agent; pore-forming agent selects bamboo wood powder for use, binder selects latex powder for use;

[0038] The parts by weight of kaolin, potassium feldspar, bamboo wood powder and latex powder are 10 parts of kaolin, 8 parts of potassium feldspar, 2 parts of powder made from flue-cured tobacco rods, and 2.5 parts of latex powder.

Embodiment 2

[0039] Embodiment 2: the difference with Example 1 is that the parts by weight of kaolin, potassium feldspar, bamboo wood powder and latex powder are the powder that 8 parts of kaolin, 9 parts of potassium feldspar, bamboo wood powder+cured tobacco rod break into ( 1:1) 3 parts, latex powder 3 parts.

Embodiment 3

[0040] Embodiment 3: The difference with Example 1 is that the parts by weight of kaolin, potassium feldspar, bamboo wood powder and latex powder are 9 parts of kaolin, 7 parts of potassium feldspar, 2.5 parts of bamboo wood powder, and 2 parts of latex powder.

Abstract

The invention discloses rare earth ceramsite and a preparation method thereof, and belongs to the technical field of environmental protection treatment. Main materials comprise kaolin and potassium feldspar, and the auxiliary materials comprise a pore-forming agent and an adhesive. The rare earth ceramsite is good in adsorption performance and high in dirt carrying capacity, and the problems thata natural filter material is single in specific gravity and prone to breakage and argillization, SiO2 is generated, and organic carbon remains for secondary pollution are solved. The rare earth ceramsite can be widely used as a filter medium in single-layer filter tanks, multi-layer filter tanks and mechanical filtration, can be used for treating various industrial sewage, industrial water, urbantap water, urban sewage, pure water and soft water, and can also be used as a biological filter material for treating organic water. In addition, the rare earth ceramsite can be used as a filter material for treating various industrial dust and boiler smoke dust.

Description

technical field [0001] The invention belongs to the technical field of environmental protection, and in particular relates to a rare earth ceramsite and a preparation method thereof. Background technique [0002] Ceramsite, as the name suggests, is ceramic particles. Most of the appearance characteristics of ceramsite are round or oval spheres. [0003] The surface of ceramsite is a hard shell, which is pottery or enamel, which has the function of water-proof and air-proof. Because there are many raw materials for the production of ceramsite, there are many varieties of ceramsite, and because there are many colors, the color of roasted ceramsite is mostly dark red, ocher red, and some special varieties are grayish yellow, grayish black, grayish white, blue gray, etc. [0004] The internal structure of ceramsite is characterized by fine and dense honeycomb micropores. These micropores are all closed, not connected. It is formed due to the gas being wrapped into the shell,...
