Problems solved by technology

However, in these regeneration methods, most of the substances adsorbed in the activated carbon are forcibly replaced or released, and the simultaneous degradation and removal of the substances adsorbed in the activated carbon is not achieved.
In addition, another disadvantage of the method involving water treatment is that the substances adsorbed by the activated carbon will soon form a dynamic equilibrium with the activated carbon in the wastewater after desorption. If you want to move the balance to the expected desorption direction, you must constantly replace recycled water
As a result, a large amount of waste water is produced

Abstract

The invention relates to an active-carbon regeneration system. The active-carbon regeneration system comprises an ultrasonic treatment device, an active-carbon regeneration container, a jet device, anozone generator and an ozone catalytic oxidation tower. The active-carbon regeneration system and method have the beneficial effects that synchronous degradation of desorbed substances in the regeneration process of the active carbon can be realized, and simultaneously water for regeneration does not need to be added in the treatment process, so that the generation of waste water is reduced, andcontinuous automatic low-cost active-carbon regeneration treatment is realized.

Description

technical field [0001] The invention relates to the field of adsorbent regeneration, in particular to an activated carbon regeneration system and method. Background technique [0002] Activated carbon is a substance with a wide range of uses, and has a wide range of applications in deodorization, decolorization, and anti-virus. The industrial or civil field mainly uses the porous adsorption capacity of activated carbon to selectively adsorb certain substances in the gas phase or liquid phase system, and then separates them from the system. For example, in gas masks and activated carbon masks, the adsorption properties of activated carbon are used to selectively adsorb harmful substances in the air, thereby achieving the purpose of air purification. Another example is the selective adsorption of activated carbon for decolorization in the food industry. Activated carbon is also widely used in the fields of environmental protection and water treatment. For example, free chlor...
