The work was done under the supervision of Professor Jaime Cuevas Rodríguez and was funded through a national research project of the Spanish Environmental Ministry. Javier Cuadros, was performed between June and September of Future articles about the content of the thesis are going to be summited in the next years.

Las conversaciones y los emails que hemos intercambiado, sin duda han jugado un importante papel en el contenido final de la tesis. No puedo imaginar una mejor compañera de laboratorio, docencia, comidas y descansos. También he tenido mucha suerte en compartir laboratorio y despacho con Manuel Rodríguez y José Gumuzzio. Ellos, junto con Santiago Leguey, Raquel Vigil y Rosario García me han proporcionado los empujones iniciales necesarios para inspirarme.

De forma especial, quisiera reconocer la labor social, ambiental y solidaria de Amigos de la Tierra, organización que conozco desde hace años. Aprecio también el tiempo dedicado por Carlos a ayudarme con el LaTeX, aunque finalmente lo utilizara en otros trabajos. Para mí, ellos son los verdaderos protagonistas. Mercedes Regadío. XVI Regadío, M. L1: leachate of deionized water L2: methanogenic synthetic leachate L3: acetogenic synthetic leachate L4: methanogenic real leachate El Garraf landfill.

An appropriate disposal of waste in landfills is a key issue for protecting, preserving and improving the environment and the human health. The most applied policy for landfilling is what is phenetic classification containment strategy complete isolation of the deposited waste by means of bottom and top liner systems and collection of gas and leachate emissions combined with everlasting aftercare monitoring.

Under these conditions, the waste itself remains a source of pollution and the problem is not solved, since if something accidentally fails, the pollutants will be released. In the present thesis, the response of natural and common Spanish clayey soils to leachate solutions in the long term is what is the graph of the linear equation that has a slope of 1/2 brainly both: i under a real approach with soil samples below five actual municipal wastes MW landfill sites years old and no engineered liners and ii under a laboratory approach based on a four-year diffusion experiment with a natural clay compacted in four 0.

The important quantity of data made it necessary to perform statistical procedures in order to i observe correlations within the measured parameters and between them and the attenuation of leachate pollutants principal component analysis and Varimax rotation and ii to know what effects caused by the different types of leachates on the parameters measured in the clayey materials, are significant multivariate analysis of variance, between-effects and multivariate tests.

The ratio decrease per meter depth Dm and a diffusive flux attenuation capacity Ac were defined for each natural substratum to study the differences between them and to compare their performance as a barrier, under normalized conditions of leachate exposure time and quantity of waste per area. The observed attenuation depths and the estimated hydraulic conductivity K in the studied natural materials proved that the minimum depth and the maximum K of a geological barrier established by.

Such ion exchange capacity is interesting for environmental remediation in contaminated sites. The important roles, in the retardation mechanisms, what is the graph of the linear equation that has a slope of 1/2 brainly water entry, sorption, biodegradation, pH buffer capacity, nature of wastes, types of clays, matrix diffusion and precipitation-dissolution equilibrium, have also been discussed.

Consequently, the long-term effectiveness of several geological barriers beneath MW landfills was analyzed in detail and reliable data relevant to design natural attenuation strategies were presented. The attenuation strategy leads to a more sustainable and more cost-effective waste management concerning i liners installation, ii drainage what is the graph of the linear equation that has a slope of 1/2 brainly gas collection systems and iii post-closure monitoring.

Therefore, this strategy results in a more affordable technology for developing countries, where water diseases related to waste pollution kill millions of people, what is the graph of the linear equation that has a slope of 1/2 brainly children, per year. XX Regadío, M. Un vertido de residuos adecuado es una cuestión clave para la protección, conservación y mejora del medio ambiente y la salud humana. Bajo estas condiciones, los propios residuos siguen siendo una fuente de contaminación y el problema no se resuelve, ya que si accidentalmente algo falla, los contaminantes se liberarían.

Esta estrategia considera el propio sustrato natural subyacente "barrera geológica como un reactor bioquímico en el que los procesos naturales dilución, dispersión, biodegradación, filtración, precipitación, rédox, adsorción o reacciones de intercambio iónico se encargan de reducir y eliminar la contaminación. La presente tesis investiga la respuesta a largo plazo de distintas arcillas naturales representativas de España, al contacto directo con lixiviados de vertederos, desde dos actividades: i bajo un enfoque real; con muestras de suelo recogidas bajo cinco vertederos de residuos urbanos RUentre 9 y 24 años de edad y en zonas carentes de barrera ingenieril, y ii bajo un enfoque de laboratorio; con muestras de un experimento de difusión con una arcilla natural compactada hasta 0.

El propósito fue estudiar las diferencias entre los sustratos y comparar sus resultados como barrera geológica, en. Esa capacidad de intercambio catiónico es interesante de cara a la remediación ambiental de sitios contaminados. Asimismo, también se ha discutido el importante papel que tienen la entrada de agua, los procesos de sorción, la biodegradación, la capacidad tampón de pH, la naturaleza de los residuos, los tipos de arcillas, la difusión y el equilibrio de precipitación-disolución, en los mecanismos de retardo en la migración de contaminantes.

En general, se ha analizado en detalle la eficacia a largo plazo de varias barreras geológicas debajo de vertederos de RU y se presentan datos fiables para el diseño de estrategias de atenuación natural.

Las figuras Fig. Minerales de la arcilla como ilitas, esmectitas y vermiculitas, tienen una carga permanente negativa en sus capas Tabla 1.

Este balance negativo de cargas es neutralizado por cationes que se introducen en las posiciones interlaminares de ilitas, esmectitas, vermiculitas. Sin embargo, la caolinita tiene idealmente carga neta neutra en sus capas, aunque en la realidad, es difícil encontrar caolinitas puras que no tengan ninguna sustitución iónica, sino que normalmente poseen una pequeña carga negativa, que se neutraliza por unos pocos asymmetric relation in discrete mathematics examples interlaminares.

Algunos de los cationes adsorbidos para neutralizar el déficit de carga de las sustituciones catiónicas, pasan así a estar en contacto con la disolución. Solución Superficie arcilla.
