Description

Tratamiento de purines para la obtención de productos biológicos naturales.Treatment of slurry to obtain natural biological products

La presente invención se refiere a un procedimiento que tiene como objetivos la retirada y la recuperación de los purines que son altamente contaminantes, su tratamiento natural, y su posterior transformación y valorización en distintos productos naturales de gran utilidad, como son la recuperación de agua para el riego, compostaje como abono natural biológico para los cultivos, un complemento nutricional natural para animales monogástricos, aceite vegetal puro, biocombustible para motores diésel, restitución de oxígeno al aire y absorción del CO_{2}.The present invention relates to a procedure that aims at withdrawal and recovery of slurries that are highly polluting, their treatment natural, and its subsequent transformation and recovery in different Natural products of great utility, such as the recovery of water for irrigation, composting as a biological natural fertilizer for crops, a natural nutritional supplement for animals monogastric, pure vegetable oil, biofuel for engines diesel, restitution of oxygen into the air and absorption of CO2.

Los purines son los excrementos sólidos y líquidos del cerdo. Son muy contaminantes, sobre todo debido a la concentración porcina en diversos puntos, por lo cual su control es obligatorio en España mediante el Real Decreto 261/96, que es la incorporación de la Directiva 91/676 de la Unión Europea. Tienen un contenido aproximado, en proporciones de Kg. por tonelada, de 2 Kg. de nitrógeno, 0'5 de fósforo y 3 de potasio. El purín esta relacionado con la biomasa residual húmeda. Generalmente sólo se utiliza como abono en países de agricultura muy retrasada. Con la invención propuesta se pretende desarrollar un procedimiento innovador, basado en la utilización de las nuevas biotecnologías, siendo de gran interés por su importante impacto medioambiental y socio-económico a nivel nacional e internacional, altamente viable y sobre todo porque propone alternativas para la lucha contra la sequía, la protección del medio ambiente, el desarrollo rural sostenible, la creación de una importante fuente de empleo, y la obtención de productos de gran valor.Purines are solid feces and Pork liquids They are very polluting, especially due to the swine concentration at various points, so its control is mandatory in Spain through Royal Decree 261/96, which is the incorporation of Directive 91/676 of the European Union. They have a approximate content, in proportions of Kg. per ton, of 2 Kg. of nitrogen, 0.5 phosphorus and 3 potassium. The slurry is related to wet residual biomass. Generally only used as fertilizer in countries with very delayed agriculture. With the proposed invention is intended to develop a procedure innovative, based on the use of new biotechnologies, being of great interest for its important environmental impact and socio-economic at national and international level, highly viable and especially because it proposes alternatives for the drought control, environmental protection, sustainable rural development, creating an important source of employment, and obtaining high value products.

Nuestra sociedad está actualmente sufriendo una serie de daños ecológicos con un impacto medio ambiental muy grave, producidas en parte por la cantidad de residuos nocivos que generan algunas industrias debido al actual modo de producción intensivo en algunos sectores, especialmente el ganadero. Este es un problema acuciante que preocupa a muchas capas de población, así como a los gobiernos, que no han logrado una solución eficaz y viable. Uno de los residuos más nocivos derivados de esta producción masiva, y que a la vez origina, por la enorme cantidad generada por las ganaderías, una contaminación extrema en tierras de cultivo, ríos y capas freáticas, y por lo tanto una catástrofe ecológica, son los purines de cerdo.Our society is currently suffering a series of ecological damage with a very serious environmental impact, produced in part by the amount of harmful waste they generate some industries due to the current intensive production mode in Some sectors, especially livestock. This is a problem pressing that worries many layers of population as well as governments, which have not achieved an effective and viable solution. One of the most harmful waste derived from this mass production, and that at the same time it originates, due to the enormous amount generated by the livestock, extreme pollution in farmland, rivers and groundwater, and therefore an ecological catastrophe, are the Pork manure.

El procedimiento que propone este documento se resume en la recogida de purines, la separación de la parte líquida de la sólida, y su posterior tratamiento y mezcla con distintos elementos para la producción de abono, complementos alimenticios, biocombustible, entre otros.The procedure proposed in this document is summarizes in the collection of slurry, the separation of the liquid part of the solid, and its subsequent treatment and mixing with different elements for the production of fertilizer, food supplements, biofuel, among others.

La patente objeto de esta invención tiene su campo de aplicación en la industria auxiliar del tratamiento de residuos, específicamente el de purines de cerdo.The patent object of this invention has its field of application in the auxiliary treatment industry waste, specifically that of pig purines.

Anteriormente ya hemos mencionado muchos inconvenientes que provocan los purines, aunque a pesar de esto, actualmente, en muchas granjas aún se siguen acumulando grandes cantidades de purines sin que sepan los encargados de estos establecimientos qué hacer con ellos. En algunos casos dichos purines son arrojados a fosas, o peor aún, a ríos u otros caudales de agua.Previously we have already mentioned many inconveniences caused by slurries, although despite this, Currently, many farms still accumulate large amounts of slurry without those in charge of these establishments what to do with them. In some cases said slurries are thrown into pits, or worse, into rivers or other flows of water.

A lo largo de los años se han intentado aportar al estado de la técnica algunos procedimientos, sistemas y dispositivos que permitan encontrar una solución definitiva a la eliminación de estos residuos, y aún más, para su transformación en productos útiles, aunque ninguno de ellos con la novedad y las ventajas que aporta la presente invención.Over the years they have tried to contribute to the state of the art some procedures, systems and devices that allow finding a definitive solution to the disposal of this waste, and even more, for its transformation into useful products, although none of them with the novelty and the advantages provided by the present invention.

Así, el documento ES 2 007 239 presenta un sistema de reciclaje de purines, en especial de purines de cerdo, caracterizado porque consta de las fases siguientes: alimentación, mezcla, extracción y desecado de las citadas fases, en la primera de ellas se verifica la alimentación de purín desde un depósito cerrado almacenador de los purines hacia un tanque, en donde se desarrolla la segunda fase o de mezcla entre dicho purín y un sólido absorbente, alimentado a su vez al tanque mezclador, esta mezcla se verifica a través de un medio agitador hasta obtener una pasta homogénea, del purín y del sólido absorbente, pasando finalmente a la tercera fase, en la que dicha pasta es extraída del tanque mezclador dispuesta para su desecado, de manera que dicha pasta se constituye en un fertilizante orgánico.Thus, document ES 2 007 239 presents a slurry recycling system, especially pig slurry, characterized in that it consists of the following phases: food, mixing, extraction and drying of the aforementioned phases, in the first of they check the slurry feed from a closed tank slurry store to a tank, where it develops the second phase or mixture between said slurry and a solid absorbent, in turn fed to the mixing tank, this mixture is verify through a stirring medium until a paste is obtained homogeneous, of the slurry and of the absorbent solid, finally turning to the third phase, in which said paste is extracted from the tank mixer arranged for drying, so that said paste is It constitutes an organic fertilizer.

En el documento ES 2 153 739 se propone un procedimiento para la depuración de purines que comprende, en una primera etapa, la separación mecánica de la fracción sólida del resto del purín, caracterizado por el hecho de que, en una segunda etapa subdividida en dos fases, se lleva a cabo el acondicionamiento del líquido resultante de la primera etapa, mediante una oxidación que utiliza ozono y una neutralización que utiliza ácido nítrico, ácido fosfórico, ácido sulfúrico u otro ácido que una vez reaccionado sea aceptable para el subsuelo y, en una tercera etapa, se realiza la destilación del líquido procedente de la segunda etapa separándose el agua de las sales presentes en el líquido.Document ES 2 153 739 proposes a procedure for purification of slurries comprising, in a first stage, the mechanical separation of the solid fraction of the slurry, characterized by the fact that, in a second stage subdivided into two phases, conditioning is carried out of the liquid resulting from the first stage, by oxidation that uses ozone and a neutralization that uses nitric acid, phosphoric acid, sulfuric acid or other acid that once reacted is acceptable to the subsoil and, in a third stage, distillation of the liquid from the second stage is performed the water separating from the salts present in the liquid.

Otra posible solución que parecía ser la más acertada es la de acelerar el proceso de fermentación para obtener metano y aprovechar la combustión del mismo para generar energía. Sin embargo, esta solución presenta numerosos inconvenientes tanto desde el punto de vista económico, de transporte como del bajo rendimiento que se obtiene. Además los materiales obtenidos no son adecuados para devolverse al subsuelo.Another possible solution that seemed to be the most Successful is to accelerate the fermentation process to obtain methane and take advantage of its combustion to generate energy. However, this solution has numerous drawbacks both from the economic point of view, of transport as of the low performance you get. In addition, the materials obtained are not suitable to return to the subsoil.

Por su parte, el documento ES 2 157 774 ofrece unas mejoras en el procedimiento de depuración de purines de cerdo, del tipo que comprende tratamientos físicos y químicos para conseguir la eliminación de la contaminación del residuo además de la acción metabólica aerobia de bacterias fijadas en el interior de un reactor biológico caracterizado por comprender tres etapas adicionales, siendo la primera etapa una higienización del purín de cerdo cuando éste se encuentra en estado virgen que consiste en el calentamiento de la masa del purín consiguiendo la conversión del nitrógeno total del purín en nitrógeno amoniacal, pasando la mencionada masa caliente a un reactor fuertemente agitado, comienzo de la segunda etapa, en el que serán añadidos distintos reactivos con los que se conseguirá la precipitación del nitrógeno amoniacal presente en la masa del purín de cerdo mediante precipitación química por formación de fosfato amónico magnésico o estruvita después de haber mantenido un tiempo de contacto corto y una vez formada la estruvita se centrifuga tras añadir un floculante orgánico adecuado de manera que la estruvita se separará junto al resto de materia sólida quedando una facción líquida exenta de compuestos nitrogenados y compuestos de fósforo pasando esta facción líquida a un reactor biológico en el que será sometida a una última etapa novedosa consistente en someter a un último calentamiento a este agua semi depurada y se produce mediante evaporación parcial efectuándose tras la evaporación un proceso de coagulación con adición de sales metálicas y llevando la mezcla a una valor de pH ácido, separándose la facción precipitada y llevando hasta un pH básico la facción líquida mediante la adición de un hidróxido, tras lo que pasaría a través de una membrana de separación con un paso de luz inferior a 1000 daltons, mezclando ambas facciones, la líquida y la concentrada, y ajustando el pH a un valor básico se obtendrá una elevada proporción de ácidos húmicos y fúlvicos utilizable en agricultura constituyendo un abono líquido de alta calidad.For its part, document ES 2 157 774 offers some improvements in the purification procedure of pig purines, of the kind that includes physical and chemical treatments for achieve elimination of waste contamination in addition to the aerobic metabolic action of bacteria fixed inside a biological reactor characterized by comprising three stages additional, the first stage being a sanitization of the slurry of pig when it is in a virgin state that consists of the heating the slurry mass converting the total nitrogen of the slurry in ammoniacal nitrogen, passing the mentioned hot dough to a heavily stirred reactor, start of the second stage, in which different reagents will be added with which the precipitation of ammoniacal nitrogen will be achieved present in the dough of the pig slurry by precipitation chemical formation of magnesium ammonium phosphate or struvite after having maintained a short contact time and once formed the struvite is centrifuged after adding a flocculant suitable organic so that struvite will separate next to the rest of solid matter leaving a liquid faction free of nitrogen compounds and phosphorus compounds passing this faction liquid to a biological reactor in which it will be subjected to a last novel stage consisting of subjecting a final warm-up to this semi-purified water and is produced by partial evaporation a coagulation process is carried out after evaporation with addition of metal salts and bringing the mixture to a pH value acid, separating the precipitated faction and leading to a pH basic liquid faction by adding a hydroxide, after what would happen through a separation membrane with a step of light less than 1000 daltons, mixing both factions, the liquid and the concentrate, and adjusting the pH to a basic value will obtain a high proportion of humic and fulvic acids usable in agriculture constituting a high quality liquid fertilizer.

Ya hemos comentado que la acumulación de purines sin un tratamiento especializado presenta una gran cantidad de inconvenientes, entre ellos la contaminación por nitratos, que es un problema generalizado y creciente que afecta a la calidad de las aguas subterráneas y supone un riesgo para la salud, especialmente en el caso de los niños. El consumo de agua con una concentración alta de nitratos tiene efectos nocivos sobre la salud. Los nitratos ingeridos son transformados en nitritos en el sistema digestivo, convirtiendo la hemoglobina en metahemoglobina, que se caracteriza por inhibir el transporte de oxígeno en la sangre. Aunque la formación de metahemoglobina es un proceso reversible, puede llegar a provocar la muerte.We have already commented that the accumulation of slurry without a specialized treatment it presents a lot of inconveniences, including nitrate contamination, which is a generalized and growing problem that affects the quality of groundwater and poses a health risk, especially In the case of children. Water consumption with a concentration High nitrates have harmful effects on health. Nitrates ingested are transformed into nitrites in the digestive system, converting hemoglobin into methemoglobin, which is characterized for inhibiting the transport of oxygen in the blood. Although the Methemoglobin formation is a reversible process, it can come To cause death.

En cuanto a la utilización de procedimientos y sistemas que se encuentran en el estado de la técnica, algunas de ellas mencionadas anteriormente, presentan varios inconvenientes como la utilización de métodos no naturales que tienen efectos secundarios y ocasionan gastos adicionales por la adquisición de elementos químicos y que exigen el desempeño únicamente de personal profesional con gran experiencia en química. Otros métodos no evitan el mal olor y eliminan sólo hasta un 30% de nitrógeno. Estos procesos tampoco permiten la absorción de CO_{2} ni la restitución de oxígeno, a la vez que no preveen la obtención de una variedad de productos útiles, de hecho, se desconoce actualmente cómo obtener tantos elementos naturales a partir de purines como se demuestra en el presente documento.Regarding the use of procedures and systems that are in the state of the art, some of they mentioned above, have several drawbacks such as the use of unnatural methods that have effects secondary and cause additional expenses for the acquisition of chemical elements that require the performance of personnel only Professional with great experience in chemistry. Other methods do not avoid the bad smell and remove only up to 30% nitrogen. These processes also do not allow the absorption of CO2 or restitution of oxygen, while not providing for a variety of useful products, in fact, it is currently unknown how to obtain as many natural elements from slurry as demonstrated in This document.

Actualmente no se conoce un procedimiento basado en un conjunto de métodos, materiales y elementos que presentan características tan novedosas y que aportan beneficios significativos frente al estado de la técnica actual, aportando una serie de avances en los elementos ya conocidos con sus ventajas correspondientes.There is currently no known procedure based in a set of methods, materials and elements that present characteristics so novel and that bring benefits significant compared to the current state of the art, providing a series of advances in the elements already known with their advantages corresponding.
