Abstract

Un procédé innovant de traitement biologique s'est montré très efficace et moins coûteux pour traiter différents polluants solubles et colloïdaux dans les rejets liquides agricoles, industriels et urbains. La présente invention consiste en un dispositif industriel qui permet la dégradation par voie biologique de la charge polluante organique des effluents. La technique a été testée avec succès dans le cas d'un rejet liquide à forte charge biologique. Le traitement a été réalisé en présence des microalgues. La dépollution des rejets dans le bioréacteur gazosiphon à boucle externe développé s'effectue en alimentation continue des rejets à traiter et par apport d'oxygénation, pour la première fois dans ce type d'appareil moyennant une ventilation. L'invention est axée sur l'administration d'une quantité importante de l'air ambiant contenant l'oxygène et le gaz carbonique nécessaires pour le traitement biologique en présence des microalgues. Cet apport est assuré pour la première fois dans ce type de réacteur par le billet d'une ventilation permettant de créer une dépression entre l'extérieur et l'intérieur du réacteur, ce qui permet d'acheminer un débit considérable d'air vers l'intérieur de l'appareil. Comparativement aux autres techniques de traitements appliqués dans des réacteurs similaires, le présent procédé s'est montré très avantageux en termes d'efficacité de traitement et de consommation énergétique. Pour le traitement du rejet d'origine agricole testé dans un appareil de 35 litres de capacité, une efficacité d'abattement de dco de l'ordre de 87,35% et un taux de décoloration de l'ordre de 90,46 % ont été enregistré pour une consommation énergétique de 0,8 w/kg dcoéliminé pendant 12 heures de traitement.An innovative biological treatment process has been shown to be very effective and less expensive for treating various soluble and colloidal pollutants in agricultural, industrial and urban liquid discharges. The present invention consists of an industrial device which allows the biological degradation of the organic pollutant load of the effluents. The technique has been successfully tested in the case of a liquid discharge with a high biological load. The treatment was carried out in the presence of microalgae. The pollution control of the discharges in the developed external loop gasosiphon bioreactor is carried out by continuous supply of the discharges to be treated and by supply of oxygenation, for the first time in this type of device by means of ventilation. The invention is focused on the administration of a large amount of ambient air containing oxygen and carbon dioxide necessary for biological treatment in the presence of microalgae. This supply is provided for the first time in this type of reactor by the ventilation ticket allowing a vacuum to be created between the outside and the inside of the reactor, which makes it possible to channel a considerable flow of air to the reactor. inside the device. Compared to other treatment techniques applied in similar reactors, the present process has been shown to be very advantageous in terms of treatment efficiency and energy consumption. For the treatment of agricultural waste tested in a 35-liter capacity device, a dco abatement efficiency of around 87.35% and a discoloration rate of around 90.46% were obtained. was recorded for an energy consumption of 0.8 w / kg of coeliminated during 12 hours of treatment.
