Conf\u00e9rence – 12 d\u00e9cembre 2019 – ENTPE \/ Vaulx en Velin<\/h2>\n\n\n\n
<\/div>\n\n\n\n

Contexte – Th\u00e9matique<\/h3>\n\n\n\n

Adapter les syst\u00e8mes d\u2019assainissement dans un contexte de changement climatique est une question de plus en plus pr\u00e9gnante pour les collectivit\u00e9s. L\u2019un des moyens possibles est l\u2019utilisation des eaux us\u00e9es comme source d\u2019\u00e9nergie.  A ce titre la digestion ana\u00e9robie des boues produites, \u00e9galement appel\u00e9e \u00ab m\u00e9thanisation \u00bb <\/strong>est de plus en plus mise en avant car elle permet une production d\u2019\u00e9nergie \u00e0 partir de la biomasse contenue dans les boues d\u2019\u00e9puration, mais \u00e9galement une r\u00e9duction des quantit\u00e9s de boues.<\/p>\n\n\n\n

Cette digestion soul\u00e8ve tout de m\u00eame de<\/strong> nombreuses questions allant de : \u00e0 partir de qu\u2019elle taille de step la m\u00e9thanisation est-elle possible ou opportune ? comment se lancer dans une digestion ? comment bien piloter\/exploiter ces installations de digestion une fois mise en \u0153uvre ?<\/p>\n\n\n\n

<\/div>\n\n\n\n

Objectif<\/h3>\n\n\n\n

L\u2019objectif de cette rencontre \u00e9tait de faire un point sur la situation fran\u00e7aise en mati\u00e8re de m\u00e9thanisation des boues de station, de rappeler le contexte r\u00e9glementaire et organisationnel de cette technique, puis d\u2019alimenter les r\u00e9flexions \/ r\u00e9pondre aux interrogations par des expos\u00e9s scientifiques-techniques \/didactiques, des retours d\u2019exp\u00e9riences et des discussions dont le fil rouge \u00e9tait \u00ab\u00a0comment am\u00e9liorer la production de biogaz? <\/em>\u00ab\u00a0.<\/p>\n\n\n\n

<\/div>\n\n\n\n

Public cible<\/h3>\n\n\n\n

Elle s\u2019adressait aux services techniques des collectivit\u00e9s, en charge de l’assainissement,
\u00e0 leurs prestataires (exploitants et bureaux d\u2019\u00e9tudes) et \u00e0 leurs partenaires.<\/p>\n\n\n\n

<\/div>\n\n\n\n

Au programme :<\/strong> <\/em><\/p>\n\n\n\n

Cette journ\u00e9e \u00e9tait centr\u00e9e sur la digestion des boues de station d’\u00e9puration, la r\u00e9duction des boues produites et, l’am\u00e9lioration de la production du biogaz  :
– \u00c9l\u00e9ments de cadrage (\u00e9tat des lieux, contexte et r\u00e9glementation actuelle & \u00e0 venir),
– Expos\u00e9s techniques \/ didactiques sur l’optimisation technique de la digestion, sur les outils au service de l’exploitation de ces ouvrages,
– Retours d\u2019exp\u00e9riences : sur les pratiques actuelles – \u00e9tudes pr\u00e9alables n\u00e9cessaires , gisements, exploitation , gestion du digesteur et valorisation \u00e9nerg\u00e9tique ,
– les perspectives et innovations futures<\/p>\n\n\n\n

Et de nombreux temps d’\u00e9changes<\/b>, au cours desquels les interventions du public ont \u00e9t\u00e9 nombreux ! Cette journ\u00e9e \u00e9tait ouverte aux collectivit\u00e9s et professionnels<\/b><\/u> engag\u00e9s dans ces d\u00e9marches, mais aussi aux collectivit\u00e9s qui doivent les mettre en place, en d\u00e9passant le strict cadre r\u00e9gional.<\/p>\n\n\n\n
