Vorrichtung und Anlage zur Schlammbehandlung mit kombinierter chemischer und biologischer Oxidation
摘要
<p>Process for stabilising sludge (1) originating from the purification of industrial and/or urban effluents containing at least a proportion of dry matter consisting essentially of fermentable organic matter, characterised in that it comprises the stages consisting in: - subjecting the said sludge to an oxidation by a radical route by adding hydrogen peroxide (7) and at least one ferrous iron salt in conditions which allow at least a proportion of the said fermentable organic matter to flocculate; - subjecting the said preoxidised and flocculated fermentable organic matter to an oxidation by a biological route (5, 6). The invention also relates to plants for making use of such a process. <IMAGE></p>
