TNT廃液(赤水)の湿式酸化処理に関する研究(物質生命化学科)

Abstract

The wet oxidation treatment of waste water, known as red water from the manufacture of TNT was studied. Qualitative analysis in red water shows that there are 30wt% of organic compounds with nitro, amino and sulfonic groups substituted in aromatic ones and the other of 70wt% is an inorganic compound of sodium sulfate. The two methods with Fenton reagent and photo Fenton reagent are adopted for the oxidation treatment. The red water was decolorized by the two methods. The efficiency of decolorizing is better for the photo Fenton method than for the Fenton method. Removal of TOC is 60% for the photo Fenton method larger than 40% for the Fenton method. As the oxidation treatment products, nitrate ions, ammonium ions and low fatty acids are confirmed.
