초록

오존을 중심으로 한 다양한 조합의 고급산화 공정(advanced oxidation process: AOP)을 이용하여 2,4,6-trinitrotoluene(TNT) 제조 공정에서 발생되는 난분해성 폐수인 red water(RW)의 유기물 및 색도 제거 연구를 수행하였다. 적용된 고급산화 공정은 O3, UV/O3, UV/O3/H2O2, UV/O3/H2O2/Fe2+ 공정이었으며, 유기물 및 색도 제거 효과는 O3

Several combinations of ozone based advanced oxidation processes were tested for the treatment of red water (RW) containing recalcitrant chemical pollutants produced from 2,4,6-trinitrotoluene (TNT) manufacturing process. O3, UV/O3, UV/O3/H2O2, UV/O3/H2O2/Fe2+ processes were tested for the treatment of RW. The order of organic and color removal efficiency was found to be : O3 ≤ UV/O3 < UV/O3/H2O2 < UV/O3/H2O2/Fe2+. The optimum conditions for the removal of organic and color in the UV/O3/H2O2/Fe2+ process were 0.053 g/min of ozone flow rate, 10 mM of H2O2 concentration and 0.1 mM of FeSO4 concentration. Organic and color removal efficiencies were 96 and 100 % respectively in the UV/O3/H2O2/Fe2+ process. tert-butyl alcohol (t-buOH) was used as the hydroxyl radical scavenger. Enhancement of hydroxyl radical production was achieved by the combination of ozone with several oxidants such as UV, H2O2, Fe2+.
