- Abstract
Currently, 2,4,6‐trinitrotoluene (TNT) explosive plants often apply activated carbon to treat aromatic nitrogen compounds in wastewater, so finding optimal measures to regenerate activated carbon is essential. The method of using microwave radiation in combination with the ionized current of nitrogen was studied. The results showed that the application of the above method helped the regeneration efficiency of activated carbon reach 95.26 % after 60 minutes of treatment. The optimum conditions were given with an microwave power of 500 W, a nitrogen pressure of 0.015 MPa. The above method has a high environmental significance when the effluent after regeneration has a chemical oxygen demand (COD) of 130 mg/l, allowing it to be discharged into the environment. The method also makes economic sense when activated carbon can be regenerated many times.
