SECTOR DE LA TÉCNICATECHNIQUE SECTOR
La presente invención se refiere a una unidad modular que ha sido especialmente concebida para aplicar eficazmente un producto coagulante para clarificación de aguas, concretamente el registrado por el propio solicitante en el documento P201231530 de fecha 03 de octubre de 2012. The present invention refers to a modular unit that has been specially designed to effectively apply a coagulant product for water clarification, specifically the one registered by the applicant himself in document P201231530 dated October 3, 2012.
ANTECEDENTES DE LA INVENCIÓNBACKGROUND OF THE INVENTION
Como es sabido, la clarificación es un proceso de tratamiento de aguas que persigue retirar de ellas los sólidos insolubles que contienen en suspensión y que son la causa de su turbidez y color. As is known, clarification is a water treatment process that seeks to remove the insoluble solids they contain in suspension and that are the cause of their turbidity and color.
Los sólidos insolubles arrastrados en suspensión por las aguas pueden ser sedimentables o coloidales (no sedimentables). Insoluble solids carried in suspension by water can be sedimentable or colloidal (non-sedimentable).
Los sólidos sedimentables se retiran del agua en un proceso de decantación natural o acelerada por la acción de sustancias orgánicas o inorgánicas que son aglutinantes de estas partículas y facilitan su sedimentación. Settleable solids are removed from the water in a natural or accelerated decantation process due to the action of organic or inorganic substances that bind these particles and facilitate their sedimentation.
Los sólidos coloidales se caracterizan por su reducido tamaño de micras o décimas de micras y por su alta estabilidad que es debida a que los factores estabilizantes priman sobre los desestabilizantes. Colloidal solids are characterized by their small size of microns or tenths of microns and by their high stability, which is due to the fact that the stabilizing factors take precedence over the destabilizing ones.
Entre otros factores estabilizantes, en el caso de coloides en suspensión en el purín que es el que nos ocupa, son de destacar: las fuerzas electrostáticas y la hidratación; y entre los desestabilizantes: el movimiento Browniano y las fuerzas de Van der Waals. Among other stabilizing factors, in the case of colloids suspended in the slurry, which is what concerns us, the following are worth highlighting: electrostatic forces and hydration; and among the destabilizers: the Brownian movement and the Van der Waals forces.
La coagulación es el proceso forzado de desestabilización de los coloides, y se consigue con la aportación de sustancias coagulantes, asegurándose su mezcla íntima con las partículas en suspensión de modo que, reduciéndose las fuerzas de separación entre ellas, o fuerzas de estabilidad, lleguen a agruparse en grumos sedimentables. Coagulation is the forced process of destabilization of colloids, and is achieved with the contribution of coagulant substances, ensuring their intimate mixing with the particles in suspension so that, reducing the separation forces between them, or stability forces, they reach group into sedimentable clumps.
La coagulación a escala industrial se empezó a aplicar a principios del siglo XIX y fue consecuencia de la observación de lo que podía lograrse mediante la adición de electrólitos. Schultze y Hardy estudiaron estas reacciones y plasmaron los resultados en las hoy llamadas reglas de Schultze-Hardy. Coagulation on an industrial scale began to be applied at the beginning of the 19th century and was a consequence of the observation of what could be achieved by adding electrolytes. Schultze and Hardy studied these reactions and expressed the results in what are now called Schultze-Hardy rules.
En ellas se dice que la coagulación es provocada por iones que tienen una carga opuesta a la de las partículas coloidales y que el poder coagulante de un ión depende, en gran medida, de su valencia. Así un ión divalente es hasta 60 veces más eficaz que otro monovalente y el trivalente hasta 1000 veces más eficaz. They say that coagulation is caused by ions that have a charge opposite to that of the colloidal particles and that the coagulant power of an ion depends, to a large extent, on its valence. Thus a divalent ion is up to 60 times more effective than another monovalent one and the trivalent one up to 1000 times more effective.
Los principales coagulantes utilizados actualmente son en consecuencia, sales de aluminio o de hierro y polímeros inorgánicos de estos metales, debido a su alta capacidad de carga iónica. The main coagulants currently used are consequently aluminum or iron salts and inorganic polymers of these metals, due to their high ionic charge capacity.
Estos coagulantes, cuya eficacia está garantizada con coloides metálicos, son prácticamente ineficaces en los casos de coexistencia en las suspensiones coloidales de sustancias orgánicas junto con las inorgánicas, como resultan ser de abundantes vertidos líquidos industriales y en particular los de la industria agropecuaria. These coagulants, whose effectiveness is guaranteed with metallic colloids, are practically ineffective in cases of coexistence in colloidal suspensions of organic substances along with inorganic ones, as happens in abundant industrial liquid discharges and particularly those from the agricultural industry.
Tratando de obviar esta problemática, el propio solicitante es titular de la patente de invención P201231530 de fecha 03 de octubre de 2012, en la que se describe un producto coagulante para clarificación de purines, que siendo del tipo consistente en una sustancia pulverulenta a base de sulfatos, carbonatos e hidróxidos, presenta la particularidad de estar conformado a partir de una mezcla de Sulfatos de Calcio y/o de Magnesio y/o de Sodio en una proporción de hasta el 60%; Carbonatos de Calcio y/o de Magnesio y/o de Sodio, en una proporción de hasta el 40%; e Hidróxidos de Calcio y/o de Magnesio y/o de Sodio en una proporción de hasta el 30%. Trying to avoid this problem, the applicant himself is the holder of invention patent P201231530 dated October 3, 2012, which describes a coagulant product for clarification of slurry, which is of the type consisting of a powdery substance based on sulfates, carbonates and hydroxides, has the particularity of being made from a mixture of Calcium and/or Magnesium and/or Sodium Sulfates in a proportion of up to 60%; Calcium and/or Magnesium and/or Sodium Carbonates, in a proportion of up to 40%; and Calcium and/or Magnesium and/or Sodium Hydroxides in a proportion of up to 30%.
Si bien este producto cumple satisfactoriamente la función para la que ha sido previsto, experimentalmente se ha podido comprobar como no existen equipos específicos diseñados para la aplicación de este producto, lo que resta efectividad al procedimiento, y es precisamente lo que ha motivado al solicitante al desarrollo de la nueva unidad modular para el tratamiento de purines y otros vertidos líquidos residuales que seguidamente se va a describir. Although this product satisfactorily fulfills the function for which it was designed, it has been experimentally confirmed that there is no specific equipment designed for the application of this product, which reduces the effectiveness of the procedure, and is precisely what has motivated the applicant to development of the new modular unit for the treatment of slurry and other residual liquid discharges that will be described below.
EXPLICACIÓN DE LA INVENCIÓNEXPLANATION OF THE INVENTION
La unidad modular para el tratamiento de purines y otros vertidos líquidos residuales que la invención propone, permite optimizar de la forma más eficaz la aplicación del producto coagulante para clarificación de vertidos líquidos, descrito en el documento P201231530, y que ha sido mejorado tanto en sus características como en sus condiciones de aplicación. The modular unit for the treatment of slurry and other residual liquid discharges that the invention proposes makes it possible to optimize in the most effective way the application of the coagulant product for clarification of liquid discharges, described in document P201231530, and which has been improved both in its characteristics as well as its application conditions.
Para ello, el dispositivo de la invención se constituye a partir de una cámara de acero inoxidable, dividida en tres zonas y cerrada superiormente con una cubierta de materiales plásticos. To do this, the device of the invention is made up of a stainless steel chamber, divided into three zones and closed on top with a cover made of plastic materials.
A partir del fluido líquido a tratar con partículas en suspensión de tamaño inferior a 2 mm el tratamiento incluye los siguientes procesos sucesivos: Starting from the liquid fluid to be treated with suspended particles smaller than 2 mm, the treatment includes the following successive processes:
a. - Proceso biológico aerobio a alta carga. to. - Aerobic biological process at high load.
b. - Separación de sólidos biológicos. b. - Separation of biological solids.
c. - Clarificación con aplicación del producto coagulante y separación de sólidos mediante discos paralelos micro porosos. c. - Clarification with application of the coagulant product and separation of solids using parallel micro-porous discs.
Las materias sólidas se descargan directamente sobre contenedor o cinta transportadora y el agua clarificada limpia y transparente se evacúa por la parte inferior de la unidad modular. The solid materials are discharged directly onto a container or conveyor belt and the clean, transparent clarified water is evacuated through the bottom of the modular unit.
De forma más concreta, el fluido líquido a tratar llega a la cámara biológica desde un depósito regulador previo a la unidad modular; en esta cámara se almacena una cantidad de fangos activos sobre unos discos rugosos de alta superficie específica realizándose una reducción de las sustancias biodegradables contenidas en el fluido, que se reducen en el proceso. More specifically, the liquid fluid to be treated reaches the biological chamber from a regulatory tank prior to the modular unit; In this chamber, a quantity of activated sludge is stored on rough discs with a high specific surface area, thereby reducing the biodegradable substances contained in the fluid, which are reduced in the process.
De estos soportes rugosos la masa de bacterias se va regruesando hasta desprenderse del soporte en pequeñas lajas bacterianas que sedimentan muy fácilmente. El fluido permanece en la cámara biológica entre 30 y 120 minutos según sus características. From these rough supports the mass of bacteria thickens until it detaches from the support in small bacterial slabs that settle very easily. The fluid remains in the biological chamber between 30 and 120 minutes depending on its characteristics.
El líquido efluente de la cámara biológica pasa por la parte inferior a un decantador estático anexo donde sedimentan la mayor parte de los flóculos bacterianos recogiéndose en la superficie un fluido decantado que clarifica muy fácilmente con la aportación del producto coagulante. The effluent liquid from the biological chamber passes through the lower part to an attached static decanter where most of the bacterial flocs settle, collecting on the surface a decanted fluid that clarifies very easily with the addition of the coagulant product.
Aplicado el producto coagulante se produce una coagulación-floculación muy rápida generándose unas partículas en suspensión densas y coherentes que se separan fácilmente. Once the coagulant product is applied, very rapid coagulation-flocculation occurs, generating dense and coherent suspended particles that are easily separated.
Como consecuencia de esta separación se obtiene unos sólidos parcialmente deshidratados (humedad 70% aprox.) que descargan directamente a contenedor o cinta transportadora, resultando un agua clarificada con muy bajo contenido en sustancias contaminantes, de manera que puede ser vertida a cauce público cumpliendo las normas actualmente en vigor. As a consequence of this separation, partially dehydrated solids are obtained (humidity 70% approx.) that are discharged directly into a container or conveyor belt, resulting in clarified water with a very low content of polluting substances, so that it can be discharged into a public waterway in compliance with the standards currently in force.

De estos soportes rugosos la masa de bacterias se va regruesando hasta desprenderse del soporte en pequeñas lajas bacterianas que sedimentan muy fácilmente. El fluido permanece en la cámara biológica definida por la zona (2) entre 30 y 120 minutos según sus características. From these rough supports the mass of bacteria thickens until it detaches from the support in small bacterial slabs that settle very easily. The fluid remains in the biological chamber defined by zone (2) between 30 and 120 minutes depending on its characteristics.
El líquido efluente del proceso biológico, pasa a una cámara zona (3) donde se decanta retirándose los fangos sedimentados, y el fluido decantado pasa al proceso físico-químico en la cámara zona (4), que constituye una zona de tratamiento, en la que se establece una dosificación de aditivos secos (8) y un dosificador de aditivos líquidos (9) que componen el producto coagulante, definiendo un decantador estático donde sedimentan la mayor parte de los flóculos bacterianos recogiéndose en la superficie un fluido decantado (agua limpia e inodora). The effluent liquid from the biological process passes to a zone chamber (3) where it is decanted, removing the settled sludge, and the decanted fluid passes to the physical-chemical process in the zone chamber (4), which constitutes a treatment zone, in which which establishes a dosage of dry additives (8) and a dispenser of liquid additives (9) that make up the coagulant product, defining a static decanter where most of the bacterial flocs settle, collecting on the surface a decanted fluid (clean water and odorless).
Así pues, y tal y como se ha dicho con anterioridad, una vez aplicado el producto coagulante se produce una coagulación-floculación muy rápida generándose unas partículas en suspensión densas y coherentes que se separan fácilmente. Thus, and as previously stated, once the coagulant product is applied, very rapid coagulation-flocculation occurs, generating dense and coherent suspended particles that are easily separated.
Como consecuencia de esta separación se obtiene unos sólidos parcialmente deshidratados (humedad 70% aprox.) que descargan directamente a contenedor o cinta transportadora, resultando por otro lado un agua clarificada con muy bajo contenido en sustancias contaminantes, de manera que puede ser recuperada en limpiezas en la propia granja o vertida a cauce público cumpliendo las normas actualmente en vigor. As a consequence of this separation, partially dehydrated solids are obtained (humidity 70% approx.) that are discharged directly into a container or conveyor belt, resulting in clarified water with a very low content of contaminating substances, so that it can be recovered in cleaning. on the farm itself or discharged into public channels in compliance with the regulations currently in force.
Finalmente, el agua clarificada limpia y transparente se evacúa a través de una salida (11) m por la parte inferior de la unidad modular. Finally, the clean and transparent clarified water is evacuated through an outlet (11) m at the bottom of the modular unit.
En cuanto al producto coagulante, se trata de un producto clarificante que contiene entre cinco y siete componentes, según características del fluido a clarificar todos ellos habituales en el tratamiento y depuración de agua en toda Europa. As for the coagulant product, it is a clarifying product that contains between five and seven components, depending on the characteristics of the fluid to be clarified, all of which are common in water treatment and purification throughout Europe.
La mejora actual que presenta este producto consiste en separar algunos de los componentes que se dosificaran en disolución del resto que permanecen dosificándose en polvo. The current improvement that this product presents consists of separating some of the components that will be dosed in solution from the rest that remain dosed in powder.
Las sustancias que se dosifican en líquido son las sales de metales de alta valencia, (aluminio, hierro y otros) por un lado y los productos coadyuvantes (polielectrolitos, almidones y otros) por otro lado. The substances that are dosed in liquid are high-valence metal salts (aluminum, iron and others) on the one hand and adjuvant products (polyelectrolytes, starches and others) on the other hand.
Las sustancias que se dosifican en polvo son sales minerales poco solubles o hidratables como son los sulfatos, carbonatos, hidratos, óxidos y silicatos de calcio y magnesio en cantidades adecuadas y proporcionadas. The substances that are dosed in powder are poorly soluble or hydratable mineral salts such as sulfates, carbonates, hydrates, oxides and silicates of calcium and magnesium in adequate and proportionate quantities.
