Abstract

Процесс обработки сточного ила включает добавление в сточный ил, имеющий первую величину pH, основного реагента на основе извести с целью повышения указанной величины pH до второй величины pH, выше первой; добавление, по крайней мере, одного органического анионного флокулянта, активного при вышеуказанной второй величине pH; флокуляцию сточного ила и разделение флокулированного ила на дегидратированный ил и жидкую фазу, где подвергаемый дегидратации ил имеет вышеуказанную первую величину pH ниже 9, а основный реагент на основе извести вызывает вышеуказанное повышение pH до вышеуказанной второй величины pH в течение менее 5 минут.
