Abstract

The invention is concerned with active carbon rebirth technology to desorption and activation with large power industry ultrasonic technology after active carbon is saturation for disposing the sewage with organic matters and heavy metal ion with filtration. The ultrasonic generator sends out high frequency surging signal and the transducer changes the high frequency sound wave to spread in medium and produce exquisite machine surge. Ultrasonic travels in cleaning medium to drive the liquid to produce lots of tiny air bubbles, those air bubbles shake intensively with the action of sound field. When the press of sound reaches to a certain value, the bubbles rise quickly and close suddenly and the close produces shock wave and thousands of atmospheric pressure to force the water-fast feculence to escape from the carbon hole to disperse in the solution. It will clean the tiny space and surface of active carbon to realize the rebirth process. It has low rebirth cost without another pollution and the renewed active carbon has better adsorption efficiency, likely 95 to 130 percent of new carbon, and the wastage is less than 0.3 percent each time. This active carbon has long work time for circulation using with low cost and wide application range.

Description

technical field [0001] The invention belongs to the field of energy conservation and environmental protection, and specifically utilizes ultrasonic technology to absorb activated carbon that is treated with filter method to treat sewage containing organic matter, heavy metal ions, etc., and desorbs and activates the regeneration technology after the activated carbon is adsorbed and saturated. technical background [0002] As an excellent adsorbent, activated carbon has been widely used in the prevention and control of environmental pollution, industrial processes, and people's livelihood, and has achieved considerable results. However, after the adsorption of activated carbon is saturated, the general industry will discard it, bury it or incinerate it. , These waste activated carbons that adsorb a large amount of organic substances and harmful substances after use will easily cause "secondary pollution" if they are not handled properly! Discarded activated carbon must be han...
