Title (EN) METHOD AND EQUIPMENT FOR DIGESTING A BIODEGRADABLE LIQUID FILTRATE
(FR) PROCÉDÉ ET ÉQUIPEMENT DE DIGESTION D'UN FILTRAT LIQUIDE BIODÉGRADABLE
Abstract:
(EN) The invention relates to the field of waste treatment and hydrothermal carbonization and concerns a method for digesting a biodegradable liquid filtrate (21), comprising: - a step of hydrothermal carbonization of a biomass (14) in a hydrothermal carbonization unit (13), to obtain a product of hydrothermal carbonization; - a step of dewatering of the product of hydrothermal carbonization into a ultra-dewatered biomass (22) and the biodegradable liquid filtrate (21); the method further comprising a step of feeding a first anaerobic digester (23) with at least a part of the biodegradable liquid filtrate (21) to generate biogas (12) and a digestate (24). The invention also concerns an equipment for digesting a biodegradable liquid filtrate.
(FR) L'invention est reliée au domaine du traitement des déchets et de la carbonisation hydrothermale, et concerne un procédé de digestion d'un filtrat liquide biodégradable (21), comprenant : -une étape de carbonisation hydrothermale d'une biomasse (14) dans une unité de carbonisation hydrothermale (13), pour obtenir un produit de carbonisation hydrothermale; -une étape de déshydratation du produit de carbonisation hydrothermale en une biomasse ultra-déshydratée (22) et le filtrat liquide biodégradable (21); le procédé comprenant en outre une étape d'alimentation d'un premier digesteur anaérobie (23) avec au moins une partie du filtrat liquide biodégradable (21) pour générer du biogaz (12) et un digestat (24). L'invention concerne également un équipement de digestion d'un filtrat liquide biodégradable.
