Saturated activated carbon adsorption and desorption regeneration process is implemented by two hot air desorption and catalytic combustion. The hot air to the catalytic system of hot air into the saturated adsorption chamber adsorption desorption operation. Desorbed concentrated organic waste into the catalytic system of heat exchangers, heat exchange with the purified catalytic bed reactor to raise the temperature of the hot air back into the preheater and the catalytic bed. Oxidation catalytic bed temperature is about 280 ℃. Desorbed concentrated organic waste is oxidized in a catalytic bed gas and decomposed into harmless heat release (reaction temperature 350 ~ 450 ℃), and then through a heat exchanger to exchange heat with the desorption system out of organic waste, the temperature drop As desorption hot air into the desorption system to about 150 ℃. Run over process purification device consisting of PLC automatic control, can desorption circulation purification system, and after the catalytic reaction heat cycle non-stop continuous operation.
