Abstract
La bioconversion des boues d'épuration en produits à valeur ajoutée est considérée comme une approche éco-respectueuse de l'environnement et économique pour la gestion de ce type de déchets.Toutefois, la biodégradabilité limitée des boues d'épuration et surtout ceux qui sont produites à l'issus d'un traitement aérobie suivit d'une étape de déshydratation mécanique avec ajout d'un agent coagulant et ou floculant. Ainsi que d'autres déchets tels que les margines (effluent liquide issus de la trituration d'huile d'olive riches en inhibiteurs d'activité biologique polyphénols ), lixiviat (liquides issus de la collecte des déchets urbaines dont l'azote ammoniacale constitue un frein biologique pour une bonne dégradation organique). La présente invention concerne,, la transformation des composés organiques dissous ou en suspension sous forme colloïdale ou particulaire, les dits composés étant associés à de la matière organique lentement biodégradable et assimilable, en composés facilement biodégradables et assimilables afin de produire avantageusement une bioconversion vers un biogaz mieux enrichi en méthane et un résidu à pouvoir fertilisant.The bioconversion of sewage sludge into value-added products is considered an eco-friendly and economical approach to the management of this type of waste. However, the limited biodegradability of sewage sludge and especially those which are produced at the end of an aerobic treatment followed by a mechanical dehydration step with the addition of a coagulant and / or flocculant. As well as other waste such as vegetable water (liquid effluent from the crushing of olive oil rich in inhibitors of biological activity polyphenols), leachate (liquids from the collection of urban waste of which ammoniacal nitrogen constitutes a biological brake for good organic degradation). The present invention relates to the transformation of organic compounds dissolved or in suspension in colloidal or particulate form, said compounds being associated with slowly biodegradable and assimilable organic matter, into easily biodegradable and assimilable compounds in order to advantageously produce a bioconversion towards a biogas better enriched in methane and a residue with fertilizing power.
