Description

EQUIPEMENT <B>DE</B> PRE-TRAITEN#NT <B>D'EFFLUENTS</B> VINICOLES POUR<B>LES</B> RENDRE<B>NON NUISIBLES A L'ENVIRONNEMENT</B> <B>Il</B> est connu que les travaux de vinification nécessitent l'utilisation d'une importante quantité d'eau pour le nettoyage des équipements des cuveries.  PRE-TREATEN <B> EQUIPMENT <B> OF EFFLUENTS </ B> VINICULES FOR <B> THE </ B> MAKE <B> NON HARMFUL TO THE ENVIRONMENT </ B> <B > It is known that winemaking requires the use of a large amount of water for the cleaning of the equipment of the vats.

Les eaux qui en sont issues sont essentiellement chargées de matières organiques (sans toutefois contenir des métaux lourds), qui imposent un traitement de effluents, indispensables vis-à-vis des problèmes d'environnement, avant tout rejet. The resulting water is mainly loaded with organic matter (but does not contain heavy metals), which imposes an effluent treatment, essential for environmental problems, before any discharge.

Les centrales d'épuration sont par ailleurs coûteuses, et disproportionnées rapport aux problèmes rencontrées dans la plupart des châteaux et exploitations vinicoles. L'équipement pour le pré-traitement des effluents vinicoles, suivant l'invention est destiné<B>à</B> assurer<B>à</B> ces effluents<B>-</B> eaux de lavage des cuves, matériels tels que filtres, pompes<B>...</B> barriques<B>-</B> un pré-traitement rapide, permettant ensuite, sans risque pour l'environnement, ainsi que sans nuisance olfactive, une évacuation des eaux d'une part, et une récupération facile des boues, lies<B>...</B> provenant des travaux de vinification, <B>Il</B> est recherché<B>à</B> partir d'effluents présentant un taux de DCO/1 de ordre de <B>5</B> g.*,d'obtenir après ces traitements, des eaux présentant un DCO/1 dix fois plus faible, notamment par une aération importante, jusqu'à l'élimination de la partie soluble bio dégradable. Wastewater treatment plants are also expensive and disproportionate to the problems encountered in most castles and wineries. The equipment for the pre-treatment of wine effluents, according to the invention is intended to <B> to <B> to </ B> these effluents <B> - </ B> tank washings water , materials such as filters, pumps <B> ... </ B> barrels <B> - </ B> a rapid pre-treatment, then allowing, without risk to the environment, as well as without odor nuisance, an evacuation water on the one hand, and easy recovery of sludge, lees <B> ... </ B> from winemaking, <B> Il </ B> is sought <B> to </ B> effluents with a COD / 1 ratio of <B> 5 </ B> g. *, to obtain after these treatments, waters having a COD / 1 ten times lower, in particular by a large aeration, until the elimination of the biodegradable soluble part.

L'équipement, suivant l'invention, est conçu pour être installé sur des propriétés de dimensions moyennes, désireuses de se débarrasser des problèmes liés epandages, ou aux sous-traitances avec enlèvement des eaux chargées et stockées comprend 2 organes: <B>I/</B> Le premier constitue simultanément le bassin<B>(17)</B> de récupération des eaux chargées en provenance de la cuverie, et le bassin d'épuration proprement dit. The equipment, according to the invention, is designed to be installed on medium-sized properties, wishing to get rid of the problems related to spreading, or to subcontracting with the removal of the loaded and stored water comprises 2 organs: <B> I / </ B> The first simultaneously constitutes the basin <B> (17) </ B> for the recovery of the loaded water coming from the vat room, and the purification basin itself.

Réalisé part les soins de l'exploitant, prévu pour recevoir l'écoulement de hectos tous les 2 jours par exemple, ce bassin<B>-</B> d'environ<B>15</B> m. de long, 2 m. de large et d'une profondeur moyenne de 2 m.<B>à</B> fond incliné<B>(18)</B> est étanché par un<B>film</B> de plastique, imperméable. 2/ Le deuxième, constitue l'équipement intégrateur de dépollution proprement dit, est monté dans une structure formant barge flottante<B>(1)</B> Fig. <B>1,</B> Pl. <B>1.</B> Il est muni sur cette figure en coupe de l'installation, et en plan<B>-</B> Fig.2, Pl. 2<B>-</B> <B>-</B> D'une turbine<B>à</B> air (2)<B>-</B> ventilateur centrifuge<B>-</B> refoulant l'air aspiré, dans des tubulures placées sous la barge<B>(5),</B> et proche du fond du bassin. Ces tubulures comportent des bornes de diffusion (4) de l'air pulsé<B>,</B> chacune de ces bornes, lestée pour demeurer stable en fond du bassin, porte<B>à</B> sa partie supérieure, une membrane <B>(16)</B> plane, comportant de multiples perforations diffusant dans les effluents de tres nombreuses petites bulles d'air (tel qu'en<B>5),</B> assurant l'oxygénation des eaux chargées. Carried out the care of the operator, intended to receive the flow of hectos every 2 days for example, this basin <B> - </ B> of about <B> 15 </ B> m. long, 2 m. wide and of an average depth of 2 m. <B> to </ B> inclined bottom <B> (18) </ B> is sealed by a <B> film </ B> of plastic, waterproof. 2 / The second is the integrating equipment depollution itself, is mounted in a floating barge structure <B> (1) </ B>. <B> 1, </ B> Pl. <B> 1. </ B> It is provided in this sectional figure of the installation, and in plan <B> - </ B> Fig.2, Pl. 2 <B> - </ B> <B> - </ B> From a Turbine <B> to </ B> Air (2) <B> - </ B> Centrifugal Blower <B> - </ B > pushing back the sucked air, in tubings placed under the barge <B> (5), </ B> and close to the bottom of the basin. These pipes have diffusion terminals (4) of the pulsed air <B>, </ B> each of these terminals, weighted to remain stable at the bottom of the basin, door <B> to </ B> its upper part, a flat <B> (16) </ B> membrane, with multiple perforations diffusing into the effluents of very many small air bubbles (such as in <B> 5), </ B> ensuring the oxygenation of charged waters.

<B>-</B> D'un agitateur monté incliné tel qu'en<B>6),</B> entraînant par un moteur lent une hélice de brassage<B>(8)</B> munie d'une collerette<B>(9).</B> Cette hélice a une double fonction<B>:</B> # d'une part agiter les eaux chargées pour accélérer leur oxygénation # d'autre part, créer un flux de liquide tout au long du bassin, effluents traversant la collerette créant des veines liquides autour du caisson flottant renouvelant le passage du liquide sur les bornes d'oxygénation. <B> - </ B> An inclined mounted agitator such as <B> 6), </ B> driving by a slow motor a brewing prop <B> (8) </ B> equipped with a flange <B> (9). </ B> This propeller has a dual function: <B>: on the one hand to agitate the charged waters to accelerate their oxygenation # on the other hand, to create a flow of liquid throughout the basin, effluents passing through the collar creating liquid veins around the floating box renewing the passage of the liquid on the oxygenation terminals.

<B>-</B> Deux pompes<B>(10)</B> et<B>(11),</B> d'aspiration et de refoulement des boues effluents chargés, en fin de traitement, destinés<B>à</B> être récupérés, (stockés) avant évacuation définitive. <B> - </ B> Two <B> (10) </ B> and <B> (11), </ B> pumps for the suction and discharge of loaded effluent sludge, at the end of treatment, intended for < B> to </ B> be recovered, (stored) before final evacuation.

La barge flottante est munie de 4 pieds<B>(13),</B> terminés par de larges sabots circulaires préférentiellement dans l'exemple décrit, et ceci non limitativement, arrondis <B>à</B> leur partie inférieure. Ces pieds permettront au caisson de se poser sur le fond<B>du</B> bassin, sans dommage pour le film d'étanchéité, lorsque, après traitement, la pompe <B>(l 0)</B> aura vidangé le bassin des eaux régénérées, présentant la pompe<B>(11)</B> au niveau nécessaire, pour,<B>à</B> son tour effectuer l'opération d'évacuation des boues. The floating barge is provided with 4 feet <B> (13), </ B> terminated by large circular hooves preferentially in the example described, and this not limited, rounded <B> to </ B> their lower part. These feet will allow the box to land on the bottom of the basin, without damage to the sealing film, when, after treatment, the pump will have drained (B 0). the pool of regenerated waters, presenting the pump <B> (11) </ B> at the necessary level, for, <B> to </ B> in turn carry out the operation of evacuation of sludge.

La barge flottante (Fig. <B>3A -</B> en coupe, et<B>3</B> B en plan<B>;</B> Pl. <B>3)</B> est ancrée dans le bassin par<B>3</B> points de fixation de chaînes ou de câbles, solidaires<B>à</B> leur extrémité libre de pieux enfoncés en terre (12). Ces liaisons présentent un mou suffisant pour permettre<B>à</B> la barge de descendre dans le bassin jusqu'à ce que les pieds prennent appui sur le barge flottante peut comporter de plus, les distributeurs pour disperser dans les effluents<B>à</B> traiter une flore adaptée<B>à</B> l'ensemencement du bassin d'oxygénation, et réaliser ou augmenter ainsi la formation et la précipitation de<B> </B> flocs ># (particules floconneuses), agrégats de matières organiques et minérales, et de micro organismes. The floating barge (Fig. <B> 3A - </ B> in section, and <B> 3 </ B> B in plane <B>; </ B> Pl. <B> 3) </ B> is anchored in the basin by <B> 3 </ B> attachment points of chains or cables, secured <B> to </ B> their free end of piles driven into earth (12). These links have sufficient slack to allow <B> to </ B> the barge to descend into the basin until the feet rest on the floating barge may further include, the distributors to disperse in the effluent <B > to </ B> treat a suitable flora <B> to seeding the oxygenation basin, and thereby achieve or increase the formation and precipitation of <B> </ B> flocs> # (particles flaky), aggregates of organic and inorganic matter, and microorganisms.

La barge flottante est munie également des supports recevant le les capteurs permettant<B>à</B> l'exploitant d'effectuer l'es contrôles de l'oxygène dissous, dans les effluents pendant le traitement, assurant ainsi la sûreté de ne refouler des eaux présentant des caractéristiques acceptées par rapport aux contraintes de l'environnement. The floating barge is also provided with supports receiving the sensors allowing the operator to carry out the controls of the dissolved oxygen, in the effluents during the treatment, thus ensuring the safety of discharge waters with accepted characteristics in relation to environmental constraints.
