Description

Aireador para procesos biológicos perfeccionado.Aerator for biological processes perfected.

Object of the invention

El presente modelo de utilidad tiene por objeto presentar un nuevo aireador para procesos biológicos de tratamiento de aguas residuales, el cual facilita la aportación de oxígeno y su homogeneización con el agua residual, para facilitar de este modo el desarrollo bacteriano.The purpose of this utility model is to present a new aerator for biological water treatment processes waste, which facilitates the supply of oxygen and its homogenization with wastewater, to facilitate this way bacterial development

El presente modelo de utilidad tiene aplicación en el campo del tratamiento de aguas residuales.This utility model has application in the field of sewage treatment.

Background of the invention

Los equipos utilizados hasta el momento en los procesos biológicos de tratamiento de aguas residuales tratan, con mayor o menor eficacia, de proveer de aire al agua objeto de la depuración, ya que la aportación de oxígeno es el elemento imprescindible para un correcto comportamiento y crecimiento de la masa bacteriana. Es precisamente la forma de aportar el aire, y por tanto el oxígeno, la base de los distintos sistemas utilizados en la actualidad, que con mayor o menor complejidad en cuanto a su diseño conducen a cumplimentar los efectos deseados.The equipment used so far in the processes Biological wastewater treatment treat, with greater or less efficient, to provide air to the water that is the object of purification, since the oxygen supply is the essential element for a correct behavior and growth of the bacterial mass. It is precisely how to provide air, and therefore oxygen, the basis of the different systems used today, which more or less complex in terms of design lead to Fill in the desired effects.

Entre estos aireadores podemos encontrar los de Flow — Rite Controls Ltd., protegido por las patentes norteamericanas US. 4,865,776 y US. 4,927,568. Esta bomba de aireación aspira el agua del fondo del tanque, y en la parte superior esta agua se pone en contacto con una corriente de aire, y el oxígeno es transferido a la misma, posteriormente, esta mezcla es devuelta al tanque manteniéndose así el tanque agitado y aireado.Among these aerators we can find those of Flow - Rite Controls Ltd. , protected by US patents. 4,865,776 and US. 4,927,568. This aeration pump sucks the water from the bottom of the tank, and at the top this water is put in contact with a stream of air, and the oxygen is transferred to it, subsequently, this mixture is returned to the tank thus keeping the tank agitated and airy.

En el aireador desarrollado por Aqua Systems Internacional N.V., se trata de un aireador que desplaza al agua hasta la superficie, donde se pone en contacto con el aire, y tiene lugar la transferencia de oxígeno.In the aerator developed by Aqua Systems International NV , it is an aerator that moves the water to the surface, where it contacts the air, and oxygen transfer takes place.

En los distintos aireadores fabricados por la firma Aqua - Aerobic Systems Inc., en uno de ellos, se incluye una bomba que toma el agua y la impulsa hacia el fondo, para de este modo, tener el tanque perfectamente agitado. Además está provisto de aireadores de membrana y difusores de burbuja para airear. En otro aireador de la misma firma, el desplazamiento del agua hacia el exterior de la superficie es similar al de un aspersor utilizado en las operaciones agrícolas. En otro de los aireadores firmados por la misma firma, además de agitar el agua también airea, pero incluso puede mantener el sistema agitado sin aireación y garantizar condiciones anóxicas para el caso de tener que aplicar un tratamiento terciario al agua residual.In the different aerators manufactured by the firm Aqua - Aerobic Systems Inc. , in one of them, a pump is included that takes the water and drives it towards the bottom, in order to have the tank perfectly agitated. It is also provided with membrane aerators and bubble diffusers for aeration. In another aerator of the same firm, the displacement of water to the outside of the surface is similar to that of a sprinkler used in agricultural operations. In another of the aerators signed by the same firm, in addition to stirring the water it also aerates, but it can even keep the system agitated without aeration and guarantee anoxic conditions in the case of having to apply a tertiary treatment to the wastewater.

Por último, nos encontramos con el sistema protegido por el modelo de utilidad español U200200404, registrado a nombre de Sogede S.A. el cual genera gotas de líquido que pone en contacto con la atmósfera, y mediante absorción del oxígeno contenido en esta, se enriquecen en este componente.Finally, we find the system protected by the Spanish utility model U200200404, registered in the name of Sogede SA which generates drops of liquid that makes contact with the atmosphere, and by absorbing the oxygen contained in it, they are enriched in this component.

Description of the invention

Para mejorar las prestaciones ofrecidas por los aireadores arriba mencionados, se presenta el aireador para procesos biológicos perfeccionado, objeto del presente modelo de utilidad.To improve the benefits offered by the aerators above mentioned, the aerator for biological processes is presented perfected, object of this utility model.

El aireador para procesos biológicos perfeccionado, parte de un planteamiento con dos variaciones principales en cuanto a la aportación de aire al conjunto del sistema. Cuando la aportación de aire se produce de una manera continua y en baja proporción mediante una bomba axial o de hélice, sumergida en el tanque del proceso propiamente dicho, que traslada el agua al reactor vertical central. Al no existir variación de nivel, esta bomba actúa como verdadero agitador de gran caudal y turbulencia. La adición del aire se produce a través de una chimenea situada en la parte superior de este compartimento.The perfected biological process aerator, part of a approach with two main variations in terms of air supply to the whole system. When the contribution of air is produced continuously and in low proportion by means of an axial or propeller pump, submerged in the tank of the proper process, which transfers the water to the vertical reactor central. In the absence of level variation, this pump acts as True agitator with high flow and turbulence. The addition of air is produced through a chimney located at the top of This compartment

Por otro lado, podemos utilizar el aireador para procesos biológicos perfeccionado con una aportación de aire discontinua y en cantidad muy superior a partir de una segunda bomba axial de gran caudal, así mismo sumergida en el tanque y que traslada el agua del proceso al reactor central a través de una placa perforada de sección suficiente al caudal manejado. En este recinto y debido a la velocidad de circulación se produce por una segunda chimenea la aspiración por vacío del aire atmosférico. A causa del alto caudal total aportado por ambas bombas, y a la fuerte turbulencia producida en la entrada del agua al reactor central se produce tanto una perfecta diseminación del aire en la mezcla agua—biomasa como una alta velocidad de circulación con sentido vertical descendente que facilita una homogeneización efectiva muy favorable para un buen desarrollo bacteriano.On the other hand, we can use the aerator for processes biological perfected with a contribution of discontinuous air and in much greater quantity from a second axial pump of large flow, also submerged in the tank and moving the process water to the central reactor through a perforated plate of sufficient section at the flow handled. In this enclosure and due at the speed of circulation is produced by a second chimney vacuum aspiration of atmospheric air. Because of the stop total flow contributed by both pumps, and the strong turbulence produced at the entrance of water to the central reactor is produced both a perfect dissemination of air in the water-biomass mixture as a high speed of movement with vertical direction descending that facilitates a very favorable effective homogenization for a good bacterial development.
