Process for treating effluents resulting from yolky wool-scouring processes.

摘要

The present invention provides an improved process for treating effluents from yolky wool scouring processes, characterised by comprising the following four stages in the order given: a) a first stage of flocculation/precipitation of the flocculable/precipitable contaminants and separation of the liquid phase from the solid phase, which consists of purification sludge; b) a stage of anaerobic treatment; c) a second stage of flocculation/precipitation and separation; and d) final aerobic treatment. d
