QUÉ SIGNIFICA BIOCHEMICAL OXYGEN DEMAND EN INGLÉS
Demanda de oxigeno bioquímico
La demanda bioquímica de oxígeno o B.O.D es la cantidad de oxígeno disuelto que necesitan los organismos biológicos aeróbicos en un cuerpo de agua para descomponer el material orgánico presente en una muestra de agua dada a cierta temperatura durante un período de tiempo específico. El término también se refiere a un procedimiento químico para determinar esta cantidad. Esta no es una prueba cuantitativa precisa, aunque es ampliamente utilizada como una indicación de la calidad orgánica del agua. El valor de DBO es más comúnmente expresado en miligramos de oxígeno consumido por litro de muestra durante 5 días de incubación a 20 ° C y se utiliza a menudo como un sustituto robusto del grado de contaminación orgánica del agua. BOD se puede utilizar como un indicador de la eficacia de las plantas de tratamiento de aguas residuales. Está listado como un contaminante convencional en la Ley de Agua Limpia de los Estados Unidos. La DBO es similar en función de la demanda química de oxígeno, ya que ambos miden la cantidad de compuestos orgánicos en el agua. Sin embargo, la DQO es menos específica, ya que mide todo lo que puede ser químicamente oxidado, en lugar de sólo los niveles de materia orgánica biológicamente activa.
definición de biochemical oxygen demand en el diccionario inglés
La definición de demanda bioquímica de oxígeno en el diccionario es una medida de la contaminación orgánica del agua: la cantidad de oxígeno, en mg por litro de agua, absorbida por una muestra mantenida a 20 ° C durante cinco días DBO.
