Abstract
The invention discloses equipment and a method for active carbon microwave activation, which relate to the environment-friendly technology and combine sewage treatment and active carbon activation. The equipment comprises a sealed shell, a microwave generator, and a resonance cavity of a sewage inlet, a sewage outlet and an exhaust hole, wherein a high temperature-resistant insulating material isarranged inside a sealed cavity body, and sewage can be continuously fed and discharged inside the cavity body. Meanwhile, when active carbon used for a long time does not work due to the much residueadsorbed on the surface of the active carbon, the theories that microwave can penetrate into medium and the medium material loses the electric field energy to heat up can be used to generate high temperature so as to regenerate the active carbon. The equipment is simple and has a compact structure; and the method for integrally activating the active carbon by using microwave is characterized by simple and safe operation and control, and rapid mounting, debugging and maintenance.

Description of drawings
Fig. 1 is the sectional front view of active carbon microwave activated equipment of the present invention.
Embodiment
Below in conjunction with accompanying drawing patent of the present invention is further specified.
Fig. 1 is the sectional front view of active carbon microwave activated equipment of the present invention.Among the figure, venting port 1, cooling spray container 2, cooling water pipeline 3, housing 4, joint flange 5, silica tube 6, microwave source 7, silica glass 8, water-in 9, collecting container 10, sludge tank 11, blow-off pipe 12, clear water discharge outlet 13.
Silica glass 8 works to prevent that water vapour from returning in the microwave source.
The volume of collecting the collecting container 10 of sewage is 2 to 30m
3, can a plurality of parallel connections.
The working process of active carbon microwave activated equipment of the present invention is as follows:
Determine suitable activationary temperature by cooling spray container 2 by temperature controller, during sewage disposal, sewage enters silica tube 6 by sewage inlet 9, plays the effect of sewage purification by the adsorption of gac, and the sewage after the processing is discharged by water outlet 13.After gac lost efficacy, water-in 9 stops into water, by the surplus water in the blow-off pipe 12 discharge gacs of silica tube 6 belows, microwave source 7 launched microwaves, microwave penetrating silica glass 8 irradiation silica tubes 6 heat up silica tube 6, carbon granule under 100-150 ℃ of temperature in the heated quarty tube 6, make the evaporation of carbon granule internal adsorption water, also volatilization thereupon of part low-boiling-point organic compound simultaneously, the dried grain of process charcoal is heated and is warming up to 150～700 ℃.Different organism raise with temperature, with the form of volatilization, decomposition, carbonization, oxidation, eliminate from the matrix of gac respectively.Usually to this stage, the absorption recovery rate of regenerated carbon has reached 60%～85%.Organism has the considerable part carbide to remain in the activated carbon capillary behind high temperature cabonization.When temperature continuation rising reaches 850 ℃, make residual carbide be gasificated into CO
