DESCRIPTIONDESCRIPTION

Le présent procédé s'applique indifféremment aux techniques de biomethanisation en continu ou semi-continu, et de compostage dit accéléré, par exemple : en silo, silo-couloir ou bioréacteur rotatif.The present process applies equally to the techniques of continuous or semi-continuous biomethanization, and of so-called accelerated composting, for example: in a silo, silo-corridor or rotary bioreactor.
Sa mise en oeuvre conduit à 1'amélioration sensible des rendements biologique et énergétique des techniques mentionnées, dont l'intégration permet simultanément l'élargissement de leur capacité de traitement au spectre complet de la biomasse des déchets, et la minimalisation, voire la suppression de leurs rejets respectifs dans l'environnement.Its implementation leads to a substantial improvement in the biological and energy yields of the techniques mentioned, the integration of which simultaneously makes it possible to widen their processing capacity to the full spectrum of the biomass of waste, and the minimization or even the elimination of their respective releases to the environment.
- Les revendications 1 à 3 établissent respectivement le concept général, les principaux facteurs interractifs et la condition associative des voies de traitement qui déterminent 1'invention.
- Le schéma général du procédé (figure 1) , représente une unité de pré-traitement (1) alimentant une ligne de biomethanisation- Claims 1 to 3 respectively establish the general concept, the main interactive factors and the associative condition of the treatment routes which determine the invention. - The general diagram of the process (Figure 1), represents a pre-treatment unit (1) supplying a biomethanization line
(2) et de compostage (3) avec-des déchets (4) .(2) and composting (3) with -waste (4).
- L'effluent liquide et les boues résiduelles de la biomethanisation (5) sont injectés dans la ligne de compostage, tandis que l'eau ou autre liquide (6) nécessaire à l'équilibre du système, lui est restituée au niveau de la ligne de biomethanisation dont les produits sont respectivement le biogaz (7) , qui fournira tout ou partie de l'énergie de process, et la fraction solide et stabilisée de son effluent (8) dont les propriétés intrinsèques permettent d'envisager la valorisation dans l'industrie agro-alimentaire.- The liquid effluent and the residual biomethanization sludge (5) are injected into the composting line, while the water or other liquid (6) necessary for the balance of the system, is returned to it at the level of the line of biomethanization whose products are respectively biogas (7), which will provide all or part of the process energy, and the solid and stabilized fraction of its effluent (8) whose intrinsic properties make it possible to envisage recovery in the food industry.
- En cas d'arrêt de la ligne de biomethanisation, son effluent injecté dans la ligne de compostage pourra être remplacé temporairement par de l'eau, évitant ainsi d'interrompre la production de compost (9) .- If the biomethanization line stops, its effluent injected into the composting line can be temporarily replaced by water, thus avoiding interrupting the production of compost (9).

Par l'intermédiaire d'une unité de pré-traitement et d'acheminement spécialement conçue, le procédé revendiqué répond avec souplesse à l'incertitude qui caractérise la distribution qualitative des déchets dans le temps, en permettant le plus large report instantanné des matières compatibles d'une ligne de traitement sur l'autre, exploitant ainsi au mieux leurs complémentarités, leurs supplémentarités et leurs capacités de charge respectives.Through a specially designed pre-treatment and routing unit, the claimed process responds flexibly to the uncertainty that characterizes the qualitative distribution of waste over time, by allowing the largest instantaneous transfer of compatible materials from one treatment line to the other, thus making the best use of their complementarities, their complementarities and their respective carrying capacities.
En outre, cette unité présente une disposition particulière d'adaptation à la nature prédominante des déchets en présence, qui peut être alternativement ligneuse et grossière ou fine et humide, par inversion de l'ordre d'engagement de ses organes de conditionnement.

Ces figures montrent encore comment sont séparés et acheminés les sous-produits du pré-traitement constitués par les jus (1.3) et les matières de faible ganulométrie (l.- j préférentiellement aiguillés vers la biomethanisation en raison de leur absence de structure, ainsi que la manière dont la fraction solide résiduelle (1.5) est en partie acheminée directement vers le compostage et en partie recyclée suivant une boucle rétroactive (1.6) permettant d'agir sur la répartition des flux.- Figures 2 Λ and 2 show schematically and without limitation the two operational variants characterized by a different order of engagement of the classification bodies (1.1) and granulo-trigger reduction (1.2) of said unit. These figures also show how the pre-treatment by-products constituted by the juices (1.3) and the materials with low ganulometry are separated and conveyed (l.- j preferably referred to biomethanization because of their absence of structure, as well as the way in which the residual solid fraction (1.5) is partly routed directly to composting and partly recycled according to a retroactive loop (1.6) allowing to act on the distribution of flows.
- Des stockages tampon (1.7) peuvent être rendus nécessaires en diverses places, suivant les conditions rencontrées dans l'approvisionnement des déchets et selon les particularités présentées par les techniques particulières de biomethanisation et de compostage engagées.- Buffer storage (1.7) can be made necessary in various places, depending on the conditions encountered in the supply of waste and according to the particularities presented by the particular techniques of biomethanization and composting engaged.
Suivant le procédé revendiqué, les conditions de la gestion interactive des deux lignes de traitement sont réalisées par la coopération directe de l'unité de pré-traitement décrite, avec deux sous-ensembles fonctionnels distinct appelés modules de transferts, et disposés en tête de chacune des lignes de traitement.According to the claimed process, the conditions for the interactive management of the two processing lines are achieved by the direct cooperation of the pre-processing unit described, with two separate functional sub-assemblies called transfer modules, and arranged at the head of each. processing lines.

déchets et combinaison de déchets organiques, elle possède dans le contexte urbain, une application privilégiée dans la mesure où, contrairement au compostage et à la biomethanisation envisagés individuellement, elle peut traiter localement, complètement et économiquement toute la fraction organique générée. waste and combination of organic waste, it has a privileged application in the urban context insofar as, unlike composting and biomethanization envisaged individually, it can treat locally, completely and economically all the organic fraction generated.
En effet par le jeu des complémentarités développées entre les deux processus, il n'est plus nécessaire de rechercher à l'extérieur des rayons de collecte des déchets, des co-substrats qui engendreraient, dans l'hypothèse d'un recours exclusif au compostage dans les zones urbaines, un gonflement de la masse totale des déchets à traiter de l'ordre d'un quart à un tiers, assorti des frais de transport correspondant.Indeed, through the play of complementarities developed between the two processes, it is no longer necessary to look outside the waste collection departments for co-substrates which would generate, in the event of an exclusive use of composting in urban areas, an increase in the total mass of waste to be treated on the order of a quarter to a third, accompanied by the corresponding transport costs.
