Resumen
El adecuado manejo de los desechos peligrosos se ha convertido en un tema de alta prioridad para todos los países y en especial para aquellos en vías de desarrollo, pues las grandes industrias son parte importante en la economía del mundo, pero a su vez también lo son en dañar el ecosistema, y no está exenta de esta la industria galvánica. Este trabajo pretende exponer un método para evitar que los desechos peligrosos constituyan un problema ambiental para Cuba. El estudio realizado está dirigido a que a través del método de estabilización/ solidificación, los lodos se asienten y dejen de causar daños al medio ambiente, el procedimiento consiste en la inclusión de los mismos en matrices de cemento Portland y cemento de bajo carbono LC3. Luego de tener los lodos encapsulados se le realizan varios ensayos para saber su comportamiento mecánico y se le hace un test de lixiviación SPLP (Synthetic Precipitation Leaching Procedure) para saber si los metales quedaron inertes. El método realizado y estudiado proyectó resultados satisfactorios en cuanto a sus propiedades físicas y así mismo son los resultados que se esperan una vez se realice el test SPLP cuando los cuerpos de prueba alcancen los 180 días de edad.
Palabras claves: galvanoplastia, residuos peligrosos, estabilización/solidificación, lixiviación, construcción.
The adequate management of hazardous waste has become a high priority issue for all countries and especially for those in the process of development, since large industries are an important part of the world's economy, but at the same time they are also important in damaging the ecosystem, and the galvanic industry is not exempt from it. This paper aims to present a method to prevent hazardous waste from constituting an environmental problem for Cuba. The study carried out is aimed at stabilizing / solidifying the sludge so that it does not cause damage to the environment. The procedure consists in including the sludge in Portland cement and low carbon cement (LC3) matrices. After having the encapsulated sludge, several tests are carried out to know its mechanical behavior and a SPLP (Synthetic Precipitation Leaching Procedure) leaching test is carried out to see if the metals were left inert. The method performed and studied projected satisfactory results in terms of its physical properties and likewise are the results that are expected once the SPLP test is performed when the test bodies reach 180 days of age. Keywords: electroplating, hazardous waste, stabilization / solidification, leaching, construction.
