Using method of electrochemical active carbon regeneration device

Abstract

The invention discloses an electrochemical active carbon regeneration device, which is characterized in that a reactor casing includes an upper layer and a lower layer, wherein a water filter device is arranged between the upper layer and the lower layer; an electrode assembly, a back flushing outlet and a water inlet distributed tube are arranged on the upper layer; active carbon is arranged between the electrode assembly and a reactor casing; and a back flushing inlet and a purified water outlet are arranged on the lower layer. During use, sewage is adsorbed by the active carbon and treatedby an electrolytic method, i.e. the sewage is not only adsorbed by the active carbon, but also is further degraded under the action of electrolysis; the active carbon is subjected to an oxidizing reaction and a reducing reaction in turn in the electrolytic state while adsorbing pollutants; and the adsorbed pollutants can be continuously decomposed, reduced and adsorbed, the high-efficiency adsorbability can be always kept and the work life can be greatly prolonged. Compared with the traditional active carbon regeneration process, the invention has the advantages of low power consumption, lessinvestment, small loss of active carbon regeneration and low regeneration cost.

Description

Technical field: [0001] The invention relates to the technical field of water treatment, in particular to an electrochemical activated carbon regeneration device and its application method. Background technique: [0002] Granular activated carbon, as a non-toxic, odorless, excellent adsorbent with well-developed internal pore structure and large specific surface area, is widely used in various projects such as urban water supply, urban domestic sewage, advanced treatment of industrial sewage, and purification of polluted water sources. and achieve satisfactory results. [0003] However, after a period of use, the adsorption capacity of activated carbon decreases and is completely lost. At this time, activated carbon is called "saturated carbon". If the saturated carbon is directly discarded without treatment, it will not only cause economic losses, but also cause secondary pollution. Therefore, finding an effective regeneration method to prolong the adsorption period of ac...
