Installation for the aerobic biodegradation of fats or so-called physico-chemical sludge in particular from agriculture and food industry

摘要

The plant, using a system for hydrolysing fat or sludge by lipases and beta-oxidation, includes a means of producing lipasic thermophilic bacteria in an independent bioreactor (A) and a biodigester (B) for hydrolysis and beta-oxidation stages. The bioreactor is integrated in the biodigester and consists of a stainless steel or plastic tube set vertically in the biodigester tank (8) while its upper end (13) has feeds (15, 16) for water and nutrients, and an outlet (20) for delivering the specific culture produced in the bioreactor to the biodigester.
