Abstract
PURPOSE: To perform efficient concentration and dewatering without using any reagent in a dewatering step, by adding a specified reagent to organic sludge, subjecting the sludge to floatation, and then mechanically dewatering the obtained scum.
CONSTITUTION: Excess active sludge 1 is subjected to floatation after addition of at least a ferrous flocculant, an oxidizing agent and an alkali. For instance, ferrous sulfate 2 and hydrogen peroxide 3 are added to the sludge, and the sludge is agitated for a few minutes and then neutralized at pH6W7 by the addition of an alkali 4 such as slaked lime or magnesium hydroxide. Thereafter, a nonionic or anionic polymer 5 is optionally added to the sludge in addition. The treated sludge is separated into floating scum 7 and floatation-separated water 8 in a floatation step 6. The floating scum 7 is introduced as such without the addition of any reagent into a filter press 9, and separated into dewatered cake 10 and cake-separated water 11. Said oxidizing agent may be ozone instead of hydrogen peroxide 3, or ozone may be used together with hydrogen peroxide.
