Description

SYSTEME D'ASSAINISSEMENT AUTONOME INDIVIDUEL ET/OU AUTONOME COLLECTIF. INDIVIDUAL AND / OR AUTONOMOUS COLLECTIVE AUTONOMOUS SANITATION SYSTEM.

Les systèmes connus comportent une fosse toutes eaux en traitement 5 primaire qui peut être en tout matériau adapté. Elle a pour fonction de recevoir les matières en suspension de l'effluent brut et la digestion anaérobie des boues décantées. Celles-ci peuvent être évacuées vers une chasse à auget flottant qui a pour fonction le stockage temporaire des effluents sortants de la fosse et de 10 libérer un volume déterminé avec un débit supérieur à l'écoulement du réseau, ce qui améliore la répartition sur un massif filtrant composé de sable qui sert à fixer les bactéries aérobie qui contribuent à l'épuration de l'effluent. The known systems comprise a pit all waters in primary treatment which can be of any suitable material. Its function is to receive suspended solids from the raw effluent and anaerobic digestion of sludge. These can be evacuated to a floating bucket hunt whose function is the temporary storage of effluents leaving the pit and to release a determined volume with a flow rate greater than the flow of the network, which improves the distribution on a Sand filtering solid which serves to fix the aerobic bacteria that contribute to the purification of the effluent.

Entre la fosse toutes eaux et le massif filtrant est parfois intercalée une 15 chasse à auget qui déverse les effluents vers la jonction des réseaux d'épandage. Between the all-water pit and the filter bed is sometimes interposed a trash hunt which discharges the effluents to the junction of the spreading networks.

L'inconvénient de la chasse à auget, lorsqu'elle est en place, elle nécessite un entretien périodique et elle a un débit insuffisant. 20 La présente invention vise à supprimer ces inconvénients. A cet effet, le système d'assainissement autonome individuel et/ou autonome collectif selon l'invention comprenant un traitement primaire constitué d'une fosse toutes eaux pour la rétention des matières en suspension de 25 l'effluent brut et la digestion anaérobie des boues décantées et un traitement secondaire comprenant un massif filtrant se caractérise en ce que entre la fosse toutes eaux et le massif filtrant est intercalé dans une cuve une auge basculeur en équilibre sur son axe longitudinal, ledit basculeur faisant au fur et à mesure de son remplissage un tour sur lui-même qui le vidange 30 complètement vers les tuyaux d'évacuation vers le massif filtrant. The disadvantage of the hunt bucket, when it is in place, it requires periodic maintenance and it has insufficient flow. The present invention seeks to overcome these disadvantages. For this purpose, the individual and / or autonomous collective sewerage system according to the invention comprising a primary treatment consisting of an all-water pit for the retention of the suspended matter of the raw effluent and the anaerobic digestion of the sludge. decanted and secondary treatment comprising a filter bed is characterized in that between the pit all waters and the filtering mass is inserted in a tank a tipping trough in equilibrium on its longitudinal axis, said rocker making as and when filling a turn on itself which empties it completely towards the evacuation pipes towards the filtering mass.

Suivant une autre caractéristique de l'invention, le basculeur a la forme d'une auge asymétrique dont l'axe longitudinal de basculement est déporté par rapport à son axe central théorique. According to another characteristic of the invention, the rocker has the shape of an asymmetric trough whose longitudinal axis of tilting is offset with respect to its theoretical central axis.

Suivant encore une autre caractéristique, le basculeur, auge asymétrique est plus large du côté de la réception des effluents. According to yet another characteristic, the rocker, asymmetric trough is wider on the side of the receipt of effluents.

Suivant encore une autre caractéristique, la cuve comportant le basculeur, auge asymétrique est dotée sous son côté le plus large par rapport à l'axe de basculement d'une rampe en arc-de-cercle orientée vers la sortie des effluents. According to yet another characteristic, the tank comprising the rocker, asymmetric trough is provided under its widest side relative to the axis of tilting of an arcuate ramp oriented towards the effluent outlet.

D'autres avantages et caractéristiques de l'invention apparaîtront à la lecture de la description ci-après d'une forme de réalisation de l'invention illustrée par les dessins joints dans lesquels : - la figure 1 est une vue en plan partielle du système d'épuration selon l'invention ; - la figure 2 est une vue en plan de la cuve contenant l'auge basculeur ; - la figure 3 est une vue en coupe transversale de la cuve selon la figure 2 avec le dispositif basculeur. Other advantages and characteristics of the invention will appear on reading the following description of an embodiment of the invention illustrated by the accompanying drawings in which: FIG. 1 is a partial plan view of the system purification device according to the invention; - Figure 2 is a plan view of the vessel containing the tipping bucket; - Figure 3 is a cross-sectional view of the vessel according to Figure 2 with the rocker device.

Tel que représenté en figure 1, le système d'assainissement représente une vue de dessus qui comporte une fosse toute eau 1 représentée de manière sommaire pour le traitement primaire des effluents qui sert à la rétention des matières en suspension de l'effluent brut et à la digestion anaérobie des boues décantées et un traitement secondaire 2 comprenant un massif filtrant de type connu comportant des tuyaux d'épandage 2 et une masse filtrante constituée de matériaux ayant de préférence une granulométrie de 6 à 30 millimètres permettant une bonne oxygénation du massif.30 Entre la fosse toutes eaux 1 et le massif filtrant 2 est intercalée une cuve 3 qui reçoit les effluents par le conduit 4 et les évacue vers le massif filtrant 2 par un ou des conduits 5. As represented in FIG. 1, the sanitation system represents a view from above which comprises an all-water pit 1 represented briefly for the primary treatment of the effluents which serves to retain the suspended solids of the raw effluent and to the anaerobic digestion of the settled sludge and a secondary treatment 2 comprising a filtering mass of known type comprising spreading pipes 2 and a filtering mass consisting of materials preferably having a particle size of 6 to 30 millimeters allowing a good oxygenation of the massif. Between the all-water pit 1 and the filtering mass 2 is interposed a tank 3 which receives the effluents via the pipe 4 and discharges them to the filtering mass 2 via one or more conduits 5.

Dans la cuve 3 est montée une auge basculeur 6 en équilibre sur son axe longitudinal 7. Avantageusement, l'auge basculeur a une forme asymétrique dont l'axe 7 de basculement est déporté par rapport à son axe central théorique. Le basculeur, auge asymétrique est en section de forme curviligne et est de largeur plus importante du côté de la réception des effluents sous le conduit 4. Cette disposition contribue au fur et à mesure du remplissage de l'auge basculeur de sa rotation autour de son axe 7 qui contribue à sa vidange complète. In the tank 3 is mounted a tipper bucket 6 in equilibrium on its longitudinal axis 7. Advantageously, the tilting trough has an asymmetrical shape whose axis 7 of tilting is offset with respect to its theoretical central axis. The rocker, asymmetric trough is in section of curvilinear shape and is of greater width on the side of the receipt of effluents under the conduit 4. This arrangement contributes as the filling of the tilting trough of its rotation around its axis 7 which contributes to its complete emptying.

La rotation de l'auge basculeur est libre autour de l'axe 7, ce qui évite tout choc sur d'éventuelles butées de retenu qui ne sont pas prévues et contribue, en fonction de son niveau de remplissage à lui faire faire un tour complet autour de son axe 7 pour sa vidange. The rotation of the tipping trough is free around the axis 7, which avoids any impact on any retained stops that are not provided and contributes, depending on its level of filling to make it a complete turn around its axis 7 for its emptying.

Le ou les orifices de sortie 5 sont disposés à l'opposé de la partie la plus large du basculeur. La cuve comportant l'auge basculeur est dotée sur son fond sur son côté le plus large par rapport à l'axe 7 de basculement et orientée vers le ou les orifices de sortie 7, dans le sens du basculement d'une rampe 8 en arc-de- cercle orientée vers la sortie des effluents vers le massif de filtration. Le basculeur se vidange instantanément. L'espace entre le basculeur et la rampe 8 est réduit, ce qui permet un accroissement de la vitesse d'écoulement des effluents qui en raison de la vitesse donnée par la rampe 8 augmente la distance de parcours des effluents dans chaque tuyau d'épandage 9. Comme représenté aux figures 2 et 3, l'axe 7 de basculement de l'auge 6 et porté sur chaque côté de la cuve 3 par des paliers 9, de préférence en un produit connu sous le nom de Téflon (marque déposée), qui sont ouverts vers le haut, ce qui facilite l'enlèvement de l'auge 6 pour son nettoyage. 20 25 The outlet or openings 5 are arranged opposite to the widest part of the rocker. The tank comprising the tipping bucket is provided on its bottom on its widest side with respect to the axis 7 of tilting and directed towards the or outlet orifices 7, in the direction of tilting of a ramp 8 in an arc -de-circle oriented towards the outlet of the effluents towards the massive of filtration. The rocker flushes instantly. The space between the rocker and the ramp 8 is reduced, which allows an increase in the flow velocity of the effluents which because of the speed given by the ramp 8 increases the travel distance of the effluents in each spreading pipe 9. As shown in Figures 2 and 3, the axis 7 tilting of the trough 6 and carried on each side of the vessel 3 by bearings 9, preferably a product known as Teflon (trademark) , which are open up, which facilitates the removal of the trough 6 for cleaning. 20 25
