Effect of potassium permanganate pre-oxidation on AOC

Tao Liang, / Jun Ma, / Huiling Liu, / Xinxin Xi,

Potassium permanganate was selected in studying the variation of AOC in preoxidation process. AOC was increased by 61.5% with the increase of oxidant dosages after coagulation. The AOC was increased by 23.6% only in preoxidation before coagulation. Permanganate preoxidation increased the substrate available for strain P17. The AOC/TOC ratio, which indicated assimilation ability of organic carbon, was increased from 8.2% to 14.0% in the preoxidations. The variation of TOC during permanganate preoxidation resulted from the variation of BDOC. The concentration of NBDOC changed little with the increase of oxidant dosages in the preoxidation processes. Permanganate preoxidation exhibited better coagulation effect with the dosage less than 1.0mg·L^-1.
