Granular carbon continuous adsorption regeneration system consists of adsorption system and regeneration system. The adsorption medium used in the adsorption part is granular carbon, which is a kind of activated carbon. Granular carbon adsorption refers to the use of its surface porous characteristics of one or more substances in wastewater adsorption to achieve the purpose of purification. The porous structure and non-polar properties of granular carbon determine its strong adsorption capacity. Theoretically, it can adsorb all the pigments and compounds existing in the materials, so that the discharge can meet the high standard requirements.

Granular activated carbon can be reused after saturated adsorption for a period of time. Granular activated carbon manufacturers introduced the following regeneration methods of granular carbon: chemical regeneration, thermal regeneration, microwave regeneration, etc. Due to the high regeneration efficiency of thermal regeneration technology, most of the large factories using activated carbon adopt thermal regeneration technology to regenerate saturated carbon.

Granular carbon adsorption regeneration technology is mainly used in the following industries:

1. Material purification: starch sugar product refining, fermentation product refining, edible oil refining

2. Water treatment: industrial sewage treatment, domestic sewage treatment and water purification treatment

3. Waste gas treatment: VOC treatment, sulfur dioxide waste gas, etc

4. Solid waste treatment: sludge incineration
