Problems solved by technology

[0008] The purpose of the present invention is to solve the problem that the existing coal-fired enterprises do not fully utilize a large amount of fly ash, which is easy to cause environmental pollution, and at the same time the cost of water treatment filter material is too high, to invent a kind of filter material made of fly ash as the main raw material. Fly ash activated regeneration composite filter material with low cost, good purification effect and capable of activation and regeneration and manufacturing method thereof

Embodiment 1

[0047] A fly ash activated regeneration composite filter material is manufactured by the following method.

[0048] First, remove the fly ash or furnace ash from the sedimentation tank, drain and dry, and take the weight 800kg. The fly ash or furnace ash is preferentially used for flue recovery type and settled in the sedimentation tank. The particle size should be ≥ 80 mesh, the smaller the particle size during actual manufacturing, the better;

[0049] Secondly, add a binder to the above-mentioned drained and cool-dried fly ash or furnace ash, mix and stir evenly. The binder can be soaked alkali flower (ie water glass) with a concentration of about 5%. The granulation requirements are appropriate;

[0050] Third, put the processed small core into the granulator. The small core can be either the small core commonly used in the granulator or the small core prefabricated with 70% kaolin, 30% attapulgite and binder. Its function is to serve as the basis of granulation. The final fly ...

Embodiment 2

[0056] A fly ash activated regeneration composite filter material is manufactured by the following method.

[0057] First, remove the fly ash or furnace ash from the sedimentation tank, drain and dry, and take the weight 900kg. The fly ash or furnace ash is preferentially used for flue recovery and settled in the sedimentation tank. The particle size should be ≥ 80 mesh, the smaller the particle size during actual manufacturing, the better;

[0058] Secondly, add a binder to the above-mentioned drained and cool-dried fly ash or furnace ash, mix and stir evenly. The binder can be soaked alkali flower (ie water glass) with a concentration of about 5%. The granulation requirements are appropriate;

[0059] Third, put the processed small nuclei into the granulator;

[0060] Fourth, send the above-mentioned fly ash or furnace ash with the binder added and uniformly stirred into a granulator for granulation to obtain fly ash particles;

[0061] Fifth, continue to add 100kg of porous alu...

Embodiment 3

[0065] A fly ash activated regeneration composite filter material is manufactured by the following method.

[0066] First, remove the fly ash or furnace ash from the sedimentation tank, drain and dry, and take the weight of 850kg. The fly ash or furnace ash is preferentially used for flue recovery type and settled in the sedimentation tank. The particle size should be ≥ 80 mesh, the smaller the particle size during actual manufacturing, the better;

[0067] Secondly, add a binder to the above-mentioned drained and cool-dried fly ash or furnace ash, mix and stir evenly. The binder can be soaked alkali flower (ie water glass) with a concentration of about 5%. The granulation requirements are appropriate;

[0068] Third, put the processed small nuclei into the granulator;

[0069] Fourth, send the above-mentioned fly ash or furnace ash with the binder added and uniformly stirred into a granulator for granulation to obtain fly ash particles;

[0070] Fifth, continue to add 150kg of po...

Abstract

The invention discloses a fly ash activation regeneration composite filtration material and a manufacture method of the filtration material, belonging to the field of water treatment technique. The fly ash activation regeneration composite filtration material consists of 80 to 90 portions of fly ashes or furnace ashes (by weight) with the grain diameter not less than 80 meshes and 10 to 20 portions of porous aluminosilicate mixed powders (by weight); the fly ash or the furnace ash are bonded as grain shape with the granularity less than 8mm; the porous aluminosilicate mixed powders are enwrapped on the surface of the fly ashes or the furnace ashes and burned so as to form a ceramic layer which is provided with an adsorption micro-hole which is communicated with an internal core. The fly ash activation regeneration composite filtration material is fabricated and formed by the steps of raw material mixing, primary granulation, secondary granulation, drying, roasting, etc., and has the advantages of low cost and good purification effect.

Description

Technical field [0001] The invention relates to a water treatment medium material, in particular to a water treatment product that can purify industrial waste water to make it reach the sewage discharge standard, and uses the deposited fly ash or furnace ash in a coal-fired chimney as the main raw material The filter material is specifically a fly ash activated regeneration composite filter material and a manufacturing method thereof. Background technique [0002] In the long river of human history, human beings and the environment have developed in a harmonious state of coexistence and coexistence. After the Industrial Revolution, especially after the Second World War, society entered a stage of modernization. This harmony was completely broken, resources were overdrawn and used, and various waste water, waste gas, and waste residues harmful to the environment flooded the ground, causing extreme pollution. Breaking the balance of nature has made people in many areas live in an e...
