Microwave And Catalysis Oxidation In Water Treatment Applications

The effectivity and applicability of active carbon and ozone/peroxide water treatment technique have been verified, and as a new water treatment means, microwave technique is being accepted gradually . Microwave and active carbon are introduced into ozone/peroxide system in the experiment , the removal capacity of microwave/ozone/peroxide system and microwave/active carbon/ozone/peroxide system on nitrotoluene is discussedo And the effect of elements, including devotion of peroxide . pH value of solution power of microwave and water quality and others on remove of nitrotoluene is also discussed ; and we analyze the oxidation products with GC-MS and LC-MS, and the results show that benzene ring can be destroyed into carboxylic acids, with the toxicity decreased . On the analysis of the oxidation product , we raise the possible route of nitrotoluene decomposition o At the same time, we found that the TOC content of nitrotoluene solution is greatly decreased after the treatment by microwave/active carbon/ozone/peroxide system , which testify the effectiveness and practicability of the method .The technique of cooperation of active carbon and micro wave. ozone is also applied in the treatment of organic sewage in the test: the combination method of active carbon adsorption and microwave/ozone oxidation is adopted in the degradation of Rhodamine B dye sewage . the results verified the effectiveness of the method in the degradation of Rhodamine B ,and the active carbon is still highly useful after treatment of vast dye sewage oIn the experiment, the method of crystal fostering and analysis in the crystal structure is first used to catch the product of phenol oxidation, which tests the existence of oxalic acid and formic acid in the oxidation product.
