Abstract

A plant installation for the purificn. of waste water by simultaneous aeration and agitation, provision being made for pumped extn. or sludge from the base of the treatment vessel. The vessel contains a vertical, freely rotatable riser pipe. Near the lower end of the riser pipe, two symmetrically opposed, radial, perforated suction pipes are joined into the riser pipe. Above the level of liq. in the vessel, two symmetrically deposed, radial discharge pipes are joined into the rise pipe. The common axis of discharge pipes is at right angles to the common axis of the suction pipes. Pref. the riser pipe is rotatable between a foot step rearing in the base of the vessel and a steady bearing fixed centrally on the underside of the vessel cover. The footstip bearing is pref. pierced to allow settled sludge to be sucked up the riser pipe by a tube passed down the riser through the steady bearing. The discharge pipes are formed to rotate the riser pipe etc. by reaction propulsion as fluid is discharged. The installation is for aerating and agitating waste water and for periodically pumping out excess sludge. The design is simple and inexpensive. All motive power can be provided by a simple air pump.

Description

DESCRIPTION
La présente invention concerne les stations d'épuration d'eaux usées pour le bon fonotionnement desquelles il est indispensable d'obtenir l'oxygénation nécessaire, un brassage conséquent provoquant l'activation des boues, et le pompage pó- riodique des boues on excédent. DESCRIPTION
The present invention relates to sewage treatment plants for the proper functioning of which it is essential to obtain the necessary oxygenation, a consequent mixing causing the activation of the sludge, and the periodic pumping of the sludge or excess.

Dans les dispositifs connus, ces différentes opérations sont réalisées par des techniques séparées, ayant peur effet une utilisation et on entretien complexes, nécessitant l'inter- vention de spécialistes.  In known devices, these different operations are carried out by separate techniques, having the effect of complex use and maintenance, requiring the intervention of specialists.

L'oxygénation et le brassage sont obtenus par un mouvement tournant des bras d'aspiration et de refoulement qui pivotent sur une crapaudine. Le mouvement de rotation est provoqué par la force de réaction du liquide sortant des bras de refoulement. Oxygenation and stirring are obtained by a rotating movement of the suction and discharge arms which pivot on a basket. The rotational movement is caused by the reaction force of the liquid leaving the delivery arms.

La circumduction du liquide est assurée par l'arrivée d'air coi- primé vers le bas de la colonne centrale. La crapaudine comporte des orifices permettant le pompage des boues.The circumduction of the liquid is ensured by the arrival of co-primed air at the bottom of the central column. The basket has holes for pumping sludge.

Les dessins annexes représentent le dispositif installé dans le station d'épuration pour habitation individuelle. The accompanying drawings represent the device installed in the treatment plant for individual housing.

Dans ce cas précis d'utilisation, le pivot 1 solidaire du couvercle 2 permet le passage du tuyau d'arrivée d'air 3. Ce tuyau fait office d'arbre et sert également au pompage des boues excédentaires. Pour cette opération de pompage, il suffit de descendre le tuyau Jusqu'i la crapaudine 4 et d'aspirer. Les bras d'aspiration 3 et de refoulement 6 sont montés en croix et reliés par une colonne centrale 7. C'est par cette colonne que le liquide remonte des bras d'aspiration aux bras de refoulement. In this specific case of use, the pivot 1 integral with the cover 2 allows the passage of the air inlet pipe 3. This pipe acts as a shaft and is also used for pumping excess sludge. For this pumping operation, it suffices to lower the pipe to the crapaudine 4 and to vacuum. The suction 3 and discharge 6 arms are mounted crosswise and connected by a central column 7. It is by this column that the liquid rises from the suction arms to the discharge arms.

Le dispesitif peut Outre utilisé dans tous les cas ou s'a- vèro nécessaire s l L'aération d'une masse liquide 2- Le brassage d'un ou plusieurs liquides avec ou sans matières en suspension. The dispesitif can Besides used in all cases or is necessary s l Aeration of a liquid mass 2- The mixing of one or more liquids with or without suspended matter.

3 Le pompage d'une certaine quantité de liquide, de dépôt, ou d'un liquide de densité différente, à la partie inférieure de la masse. 3 Pumping a certain amount of liquid, deposit, or a liquid of different density, at the bottom of the mass.
