A TREATMENT METHOD FOR NITROAROMATIC COMPOUNDS USING ZERO-VALENT IRON AND MANGANESE OXIDE

摘要

1. This invention belongs to the art described in the claims ; The present invention relates to a processing method such as the ground water, surface water, soil and waste water contaminated with an aromatic compound containing nitrogen, such as explosive TNT. ; 2. SUMMARY OF invention to solve the ; The invention TNT (2,4,6-trinitrotoluene) disadvantages of the conventional biological treatment method according to the microorganism in the process of the aromatic nitrogen compound, including an explosive material such as While the complementary, yet at the same time effective to provide a chemical (non-biological) treatment method that can be processed economically. ; 3. Solution subject matter of the invention ; The invention TNT (2,4,6-trinitrotoluene) and aromatic nitrogen compounds (nitroaromatic compounds) primarily nitric acid group of the aromatic nitrogen compound in the treatment of (-NO ₂ , zero-valent iron the nitro-group) as a reducing agent by using the [Fe (0)] amine groups (treatment reduced to amino-group), and the reduced product thus produced using a re-manganese oxide by oxidizing the oxidation-coupling reaction with the shared derived ultimately environmentally harmless and stable natural organic matter and a method of treatment in a similar fashion by converting unused microorganisms, unlike a conventional chemical treatment for the decomposition and processing techniques and also characterized in that the treatment method of the detoxification and stabilization than the process carried out by the decomposition. ; 4. An important use of the invention ; aromatic nitrogen compounds contaminated groundwater and surface water, such as TNT, is used in the treatment and purification of rainfall runoff, wastewater, etc. from the soil and contaminated soil.
