Abstract

PURPOSE: To prevent biological activity blocking and effectively remove malodorous materials by subjecting the malodorous-material-contg. KP drain formed in a kraft pulp plant to a light degree of air oxidation then treating the same by a pure oxygen activated sludge method.
CONSTITUTION: After the malodorous-material-contg. KP drain formed in a kraft pulp plant is subjected to air oxidation by blowing a small amount of air for 3W4hr, it is treated by a pure oxygen activated sludge method. Thereby, the amount of hydrogen sulfide in the water after the treatment is kept at ≤50ppm in the value in terms of sulfur and the amount of methyl mercaptan at ≤25ppm in the value in terms of sulfur, and biological activity blocking is prevented.
