The regeneration process of activated clay waste

The regeneration process of activated clay waste

 

Liaoning active clay is a kind of adsorbent which is made of clay (mainly bentonite) as the material, through inorganic acidification treatment, and then through water rinsing and boring. Its appearance is milky white powder, odorless, tasteless, nontoxic, strong adsorption function, and it can absorb colored and organic substances. Here is a detailed introduction to the regeneration process of activated clay waste residue in Liaoning Province:

 

1. The waste residue of Liaoning active clay was mixed with sulfuric acid solution;

 

2. Make the mixed mud into solid;

 

3. Firing the solid at 600 ℃ ~ 700 ℃;

 

4. Smash the solid after firing. The regeneration method of Liaoning active clay waste residue provided by the invention, which is used for acidification treatment and high temperature roasting of Liaoning active clay waste residue, has the advantages of simple process, short time, convenient operation and continuous chemical industrial production; the regenerated Liaoning active clay can be reused, save funds, avoid long-term occupation and accumulation of peculiar smell, and pollute the surrounding environment; transportation The effect is basically the same as the first time, and it can be regenerated repeatedly. It can also be used for drinking water treatment, removal of nitrite, fluoride and so on.
