Attapulgite activated carbon haydite filter board

Abstract

The invention discloses an attapulgite activated carbon haydite filter board; and the key point of the technical scheme of the attapulgite activated carbon haydite filter board is that the attapulgite activated carbon haydite filter board comprises a high viscosity attapulgite clay powder, attapulgite clay tailings powder, coal ash, anthracite culm, acidified sawdust powder and kaoline tailing powder. The components of the attapulgite activated carbon haydite filter board are mixed, formed in a pressing manner, maintained, roasted and cooled and then are packed into the attapulgite activated carbon haydite filter board. The attapulgite activated carbon haydite filter board has rough surfaces with multiple micropores, internally contains plenty of high-quality activated carbon and fine air holes and has a large specific surface area, light weight, high abrasive resistance strength, large adsorption capacity, good filtration effect, little water consumption of back washing and long service life. The coal ash and the tailings are comprehensively used for producing the attapulgite activated carbon haydite filter board, thereby being beneficial to the increasing of the comprehensive utilization rate of resources, making waste profitable and protecting environments; and the attapulgite activated carbon haydite filter board is suitable for water treatment engineering.

Description

technical field [0001] The invention relates to ceramsite, in particular to an attapulgite activated carbon ceramsite filter plate. Background technique [0002] Activated carbon has a large specific surface area, fast adsorption speed and high purification degree. It is widely used in chemical industry, electronics, medicine, printing and dyeing, food and domestic water, industrial water, solution filtration, adsorption, purification, impurity removal and decolorization. However, the activated carbon supplied on the market is loose in texture and low in hardness. Under the action of external force, the micropores are easy to block, deform and depowder, and it is difficult to maintain the original state. The backwashing used for water treatment consumes a lot of water, and the price of activated carbon higher. [0003] 80% of my country's mineral resources are associated mines, a large amount of valuable resources are stored in tailings, and tailings stockpiles require a la...

Problems solved by technology

The disadvantages of the above-mentioned patents are: the various ingredients are "fully mixed with water", and after being roasted at 800-1100°C for 5-18 hours in a closed container, the potter's clay and cork, hardwood powder and bone meal cannot be fully formed. A whole particle, pottery clay is in the shape of sand grains, and most of the cork, hardwood powder and bone meal have become ashes and cannot be made into "activated carbon ceramsite composite filter material"
