Problems solved by technology
At present, more and more activated carbon adsorption is used in the sewage treatment process, but there is no fundamental solution to the regeneration of activated carbon. The activated carbon microwave activation equipment can activate the activated carbon as a whole with a recycling rate of 100% and low energy consumption.
[0003] The traditional activated carbon regeneration method adopts chemical method, high temperature heating method, etc. Their disadvantages are: the activated carbon cannot be activated as a whole, and the normal operation of the equipment cannot be guaranteed during the regeneration process, the regeneration rate is low, and the energy consumption is high.

Embodiment Construction
[0022] The patent of the present invention will be further described below in conjunction with the drawings.
[0023] figure 1 It is a sectional front view of the activated carbon microwave activation device of the present invention. In the figure, the exhaust port 1, the cooling spray container 2, the cooling water pipe 3, the shell 4, the connecting flange 5, the quartz tube 6, the microwave source 7, the quartz glass 8, the water inlet 9, the water collection container 10, and the sludge Tank 11, sewage pipe 12, clear water discharge port 13.
[0024] The shell 4 is welded by Q235 steel plate, which serves to fix the quartz tube 6 and prevent microwave leakage. The middle part of the shell 4 is cylindrical, and the upper and lower parts are conical. At the junction of the upper, lower and middle parts, two parallel connecting flanges 5 are horizontally provided. The two connecting flanges 5 are provided with a plurality of through holes. , The majority of the through holes on...

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
Technical field [0001] The invention relates to the technical field of environmental protection, and is a device that combines sewage treatment and activated carbon activation. Specifically, it is a device and method that can use microwave energy to activate activated carbon as a whole to regenerate activated carbon while treating domestic sewage and industrial wastewater. Background technique [0002] With the continuous development of society, people's awareness of environmental protection is also increasing, and the requirements for the treatment of various sewage are getting higher and higher. At present, more and more activated carbon adsorption is used in the sewage treatment process. However, there is no fundamental solution to the problem of activated carbon regeneration. The activated carbon microwave activation equipment can activate the overall activated carbon recycling rate to 100%, and the energy consumption is low. [0003] The traditional activated carbon regenerati...
