Abstract
I1 est décrit un procédé de dégradation biologique de graisses et déchets graisseux, dans lequel an place les graisses dans une cuve de dégradation en présence de boues activées et d'eau, on injecte de l'air de manière à satisfaire la plus élevée des deux valeurs suivantes :
apport d'oxygène correspondant à la DCO et brassage correspondant à un gradient de vitesse minimum de 1.00 s-1, an ajoute du phosphore et de l'azote pour maintenir à au moins 5/1 le rapport azote/phosphore pour 100 parties de carbone organique en maintenant le pH
entre 6,5 et 8,5, et on retire de la cuve un produit à
teneur en graisses réduite. Ce procédé s'applique particulièrement au traitement des graisses et déchets graisseux provenant des eaux usées. I1 is described a method of biological degradation of grease and fatty waste, in which an fats in a degradation tank in the presence of activated sludge and water, we inject air so to satisfy the higher of the following two values:
oxygen supply corresponding to COD and mixing corresponding to a minimum speed gradient of 1.00 s-1, year adds phosphorus and nitrogen to keep the nitrogen / phosphorus ratio at least 5/1 to 100 parts of organic carbon while maintaining the pH
between 6.5 and 8.5, and a product is removed from the tank reduced fat content. This process applies particularly in the treatment of fats and waste greasy from wastewater.
