Abstract

Le procédé permet la désodorisation par adsorption des gaz d'usines d'équarrissage. Les gaz passent à travers des couches de tourbe ensemencees de bactéries. Du glucose ou du lactosérum et des phosphates en quantités convenables sont ajoutés dans les couches de tourbe pour assurer le développement bactérien. Les bactéries sont apportées dans la tourbe sous forme de boues issues de stations d'épuration bilogique.The process allows deodorization by adsorption of rendering plant gases. The gases pass through layers of peat seeded with bacteria. Glucose or whey and phosphates in suitable quantities are added to the peat layers to ensure bacterial growth. The bacteria are brought into the peat in the form of sludge from biological treatment plants.
