Abstract

Wastewater treatment station with oxygen transfer improvement. It comprises: reactor (1) to receive waste water to be purified; aeration means, for introducing into the reactor (1) bubbles (5) of oxygen-containing fluid; at least one basket (10), inside the reactor (1); and a plurality of interaction bodies (11) housed in the basket (10). The basket (10) comprises a cross-linked lateral surface provided with first openings (12) to allow access to the interior of the basket (10) of both the active sludge and the bubbles (5). The interaction bodies (11) float disorderly suspended in the mud inside the baskets (10), to intercept the bubbles (5) and interrupt the rise of said bubbles (5). It allows increasing the residence time of the bubbles (5) and therefore increasing the transfer of oxygen to the waste water. (Machine-translation by Google Translate, not legally binding)

funcionamiento de la EDAR, se pueden incluir determinados controles, según se indica seguidamente. En particular, en elaboración de los experimentos con el reactor (1) prototipo mostrado en la figuras 1 y 2, se incluyó un colector de aire (16), tal como un campana flotante captadora de gases de escape o similar (también conocida en el sector como "campana de tipo off-gas"). El colector de aire (16) está montado en la parte superior (9) del reactor (1) y se emplea para recoger el aire que escapa del reactor (1). Se incluye adicionalmente un primer medidor (17), tal como una estación meteorológica, para medir las fracciones molares de gases, tales como CO2, N2, O2 y H2O, a la entrada del colector de aire (16). Asimismo, se emplea un segundo medidor (18) para medir las fracciones molares a la salida del colector de aire (16). Un tercer medidor (19) permite medir la concentración de oxígeno en el fango activo. operation of the WWTP, certain controls may be included, as indicated below. In particular, in developing the experiments with the prototype reactor (1) shown in Figures 1 and 2, an air manifold (16) was included, such as a floating exhaust fume hood or the like (also known in the sector such as "off-gas type hood"). The air manifold (16) is mounted on the top (9) of the reactor (1) and is used to collect the air that escapes from the reactor (1). Additionally, a first meter (17), such as a weather station, is included to measure the molar fractions of gases, such as CO2, N2, O2 and H2O, at the inlet of the air manifold (16). Likewise, a second meter (18) is used to measure the molar fractions at the outlet of the air manifold (16). A third meter (19) allows the concentration of oxygen in the active sludge to be measured.

La disposición de los controles indicados, comandados por una unidad de control (20), permite obtener una medida de la variación de oxígeno que se da en el aire que sale por la parte superior (9) del reactor (1), con respecto del aire que se suministra al reactor (1) a través de los medios de aireación. A partir de dichas mediciones tomadas, tanto para oxígeno como para dióxido de carbono, se obtiene el rendimiento en transferencia de oxígeno en condiciones estándar (SOTEpw) y, aplicando la norma ASCE 18-1996 de la American Society of Civil Engineers, se calcula el rendimiento en la transferencia de oxígeno en condiciones reales (OTEpw). The arrangement of the indicated controls, commanded by a control unit (20), allows to obtain a measure of the variation of oxygen that occurs in the air that exits the upper part (9) of the reactor (1), with respect to the air that is supplied to the reactor (1) through the aeration means. From these measurements taken, both for oxygen and for carbon dioxide, the yield in oxygen transfer under standard conditions (SOTEpw) is obtained and, applying the ASCE 18-1996 standard of the American Society of Civil Engineers, the Oxygen transfer performance under real conditions (OTEpw).

Para ilustrar la aportación de la invención, seguidamente se muestran y se comentan los resultados obtenidos en varios casos realizados según la metodología explicada. To illustrate the contribution of the invention, the results obtained in several cases carried out according to the methodology explained are shown and discussed below.

Los ensayos se han realizado con una planta piloto de fangos biológicos con un volumen de 0,40 m3 y un calado de 4,15 m, alimentado con fango biológico de la propia instalación, contemplando distintos escenarios: variaciones en la naturaleza de los elementos de difusión; variaciones en la profundidad (respecto del calado o respecto de de los elementos de difusión) de la cesta (10) empleada o, en su caso, de la cesta (10) superior; variaciones en la proporción unitaria de volumen de las cestas (10) ocupado por un relleno formado por los cuerpos de interacción (11); instalación o no de mallas (14) perforadas. En todos los experimentos se ha considerado un caudal de fango activo de 2 m3/h y un caudal de aire de 1 Nm3/h. The tests have been carried out with a pilot plant of biological sludge with a volume of 0.40 m3 and a draft of 4.15 m, fed with biological sludge from the facility itself, contemplating different scenarios: variations in the nature of the elements of diffusion; variations in the depth (with respect to the draft or with respect to the diffusion elements) of the basket (10) used or, where appropriate, of the upper basket (10); variations in the unit volume ratio of the baskets (10) occupied by a filling formed by the interaction bodies (11); installation or not of meshes (14) perforated. In all experiments, an active sludge flow of 2 m3 / h and an air flow of 1 Nm3 / h have been considered.
