Description
Instalación para la depuración de purines.Installation for purification of slurry.
La presente invención se refiere a una instalación que ha sido especialmente concebida para llevar a cabo de forma sencilla la depuración de purines, permitiendo reutilizar el agua asociada a los mismos para el regadío, sin riesgo de contaminación para dichos cultivos.The present invention relates to a installation that has been specially designed to carry out in a simple way purification of slurry, allowing reuse the water associated with them for irrigation, without risk of contamination for such crops.
En la actualidad, los purines se suelen almacenar en fosas practicadas al efecto en el terreno colindante de la instalación ganadera de que se trate, suponiendo un gran problema medioambiental, dado que éstos contienen un componente líquido importante, que se filtra a través del suelo o fondo de la fosa, pudiendo alcanzar a flujos de aguas subterráneas, con su consecuente contaminación.Nowadays, slurries are usually store in pits for this purpose in the adjoining terrain of the livestock facility in question, assuming a big problem environmental, since these contain a liquid component important, that seeps through the floor or bottom of the pit, being able to reach groundwater flows, with its consequent pollution.
Si bien este problema puede solucionarse mediante el revestimiento de dichas fosas con materiales aislantes, dado el gran volumen de generación de purines en ciertas explotaciones, el tamaño de dichas fosas debe ser considerable, con una ocupación volumétrica así pues importante, y con unos costes de eliminación de dichos purines elevados.While this problem can be solved by coating said pits with insulating materials, given the large volume of slurry generation in certain farms, the size of these graves must be considerable, with a volumetric occupation thus important, and with costs of elimination of said high slurry.
La instalación para la depuración de purines que la invención propone resuelve de forma plenamente satisfactoria la problemática anteriormente expuesta, merced a permitir depurar dicha generación de purines según se van generando, sin necesidad de tener que disponer de voluminosos depósitos de recogida de los purines, y permitiendo aprovechar el agua asociada a los mismos, una vez depurada, para el riego de cultivos.The installation for purification of slurries that the invention proposes resolves in a fully satisfactory manner the problematic previously exposed, thanks to allow debugging said generation of slurries as they are generated, without having to have bulky waste collection tanks, and allowing to take advantage of the water associated with them, once purified, for irrigation of crops.
Para ello, y de forma más concreta, se ha previsto que en la instalación se establezca un depósito de recepción de los purines generados, los cuales podrán estar en estado sólido o líquido, de manera que dicho depósito incorpora medios de homogeneización para la mezcla, tales como agitadores mecánicos, hidráulicos o similares.To do this, and more specifically, it has been provided that a deposit of reception of the generated slurries, which may be in solid or liquid state, so that said deposit incorporates homogenization means for mixing, such as stirrers Mechanical, hydraulic or similar.
A los purines contenidos en el depósito de homogeneización se le añadirán una serie de nutrientes, materializados en manganeso, carbonato cálcico, cloruro de potasa y ácido cítrico.To the slurry contained in the deposit of homogenization a series of nutrients will be added, materialized in manganese, calcium carbonate, potash chloride and citric acid.
Estos nutrientes permiten llevar a cabo una mejor unificación de las dos fases (líquida-sólida) de los purines, para que una vez unificada la mezcla, ésta pase a un reactor biológico en el que se inyecta aire a través de una pluralidad de inyectores alojados en su fondo y asistidos por el correspondiente compresor.These nutrients allow to carry out a better unification of the two phases (liquid-solid) of the slurry, so that once the mixture is unified, it passes to a biological reactor in which air is injected through a plurality of injectors housed in its bottom and assisted by the corresponding compressor.
En dicho reactor, se lleva a cabo el cultivo de bacterias aeróbicas, las cuales micronizan la materia orgánica hasta licuarla.In said reactor, the cultivation of aerobic bacteria, which micronize organic matter up to liquefy it.
Los purines así tratados pasan a un depósito desnitrificador en el que las bacterias anteriormente cultivadas, y ante la falta de oxígeno en dicho depósito, se alimentan del nitrógeno, destruyéndolo.The slurry treated in this way goes to a tank denitrifier in which previously grown bacteria, and in the absence of oxygen in said tank, they feed on nitrogen, destroying it.
Se consigue así llevar a cabo la eliminación del nitrógeno, altamente contaminante.It is thus possible to carry out the elimination of nitrogen, highly polluting.
A la salida del desnitrificador se ha previsto que se establezca un segundo reactor biológico, de menor volumen de tratamiento de los purines, con el que se consigue un mayor grado de depuración, para el agua procedente de los purines, de manera que a la salida del mismo se establece un decantador en el que el agua decana se aprovecha para el riego de cultivos, mientras que las partículas de materia orgánica que pudieran quedar decantadas en el fondo del decantador se hacen recircular hasta el depósito de homogeneización mediante el correspondiente sistema de bombeo.At the exit of the denitrifier it is planned that a second biological reactor be established, with a smaller volume of treatment of slurries, with which a greater degree of purification, for water from slurry, so that the output of it settles a decanter in which the water Dean is used to irrigate crops, while organic matter particles that could be decanted in the bottom of the decanter are recirculated until the deposit of homogenization by means of the corresponding pumping system.
Cabe destacar que la geometría de los depósitos descritos puede variar para adaptarse al terreno disponible en cada momento, adquiriendo cualquiera de las geometrías habituales de éste tipo de instalaciones.It should be noted that the geometry of the deposits described may vary to adapt to the available terrain in each moment, acquiring any of the usual geometries of this one type of facilities
Asimismo, los flujos y reflujos de material entre los depósitos descritos pueden variar en función de las características del purín a depurar y de las características de las conducciones empleadas en la instalación, siendo en cualquier caso el objetivo de éstos reflujos siempre la obtención del mínimo posible de fango con el mínimo contenido de contaminantes tóxicos.Likewise, material flows and refluxes between the deposits described may vary depending on the characteristics of the slurry to be purified and the characteristics of the conduits used in the installation, being in any case the objective of these refluxes always obtaining the minimum possible sludge with the minimum contaminant content Toxic
Opcionalmente podrán utilizarse otro tipo de bacterias distintas a las presentes en los purines, en el seno de los reactores biológicos, para la descomposición de la materia orgánica.Optionally, another type of bacteria other than those present in slurries, within the biological reactors, for the decomposition of matter organic
Para complementar la descripción que se está realizando y con objeto de ayudar a una mejor comprensión de las características del invento, de acuerdo con un ejemplo preferente de realización práctica del mismo, se acompaña como parte integrante de dicha descripción, un único juego de dibujos en donde con carácter ilustrativo y no limitativo, se ha representado un diagrama esquemático de los distintos elementos que participan en una instalación para la depuración de purines realizada de acuerdo con el objeto de la presente invención.To complement the description that is being performing and in order to help a better understanding of the characteristics of the invention, according to a preferred example of practical realization of it, is accompanied as an integral part of said description, a single set of drawings where with character illustrative and not limiting, a diagram has been represented schematic of the different elements that participate in a installation for purification of slurry carried out in accordance with the object of the present invention.
A la vista de la figura reseñada, puede observarse como en la instalación para la depuración de purines que se preconiza se establece un depósito homogeneizador (1), al que acceden los purines a través de una conducción (2), el cual incorporará en su seno medios de agitación (3), de su contenido, ya sean mecánicos o hidráulicos, en orden a homogeneizar la mezcla de las fases sólida y líquida de los purines.In view of the review figure, you can be observed as in the installation for purification of slurries that It is recommended to establish a homogenizer tank (1), to which access the slurry through a conduit (2), which it will incorporate stirring means (3), of its content, already be mechanical or hydraulic, in order to homogenize the mixture of the solid and liquid phases of the slurry.
Complementariamente, se ha previsto que dicho depósito cuente con un dosificador (4) a través del que se añade una mezcla de manganeso, carbonato cálcico, cloruro de potasa y ácido cítrico a la mezcla de purines, facilitando la unificación entre sus dos fases.In addition, it is expected that said tank has a dispenser (4) through which a mixture of manganese, calcium carbonate, potassium chloride and acid citric to the slurry mixture, facilitating the unification among its Two phases.
