Part of the book series: Soil & Environment ((SOEN,volume 5))

Summary

Vertical circulation flows have been established with in-situ remediation techniques. Their hydraulic flow field permits physical and biological remediation of the saturated, as well as the unsaturated subsoil. A special advantage is that these techniques can be combined with any appropriate in-well or on-site technique. Even addition of nutrients and/or electron acceptors for stimulating biological degradation processes is possible. This paper discusses the different remediation techniques, the numerical results on the systems radius of influence and time behavior and the validation of these results in field experiments in a contaminated research site.

Kurzfassung

Vertikale Kreisströmungen wurden mit In-situ-Sanierungstechniken erstellt. Ihr hydraulisches Strömungsfeld ermöglicht eine physikalische und biologische Sanierung des gesättigten und ungesättigten Unterbodens. Ein besonderer Vorteil ist, daß diese Verfahren mit jeder geeigneten In-well- oder On-site-Technik kombiniert werden können. Sogar die Hinzufügung von Nährstoffen und/oder Elektronenakzeptoren zur Beschleunigung des biologischen Abbaus ist möglich. Im vorliegenden Beitrag werden die verschiedenen Sanierungsverfahren und die numerischen Ergebnisse des Einfluß-bereiches und des Zeitverhaltens des Systems diskutiert sowie die Verifizierung dieser Ergebnisse anhand von Feldversuchen im Rahmen eines Forschungsvorhabens erörtert.

Résumé

Des flux de circulation verticale ont été établis dans des techniques d’assainissement in situ. Leur champ de flux hydraulique permet un assainissement physique et biologique du sous-sol saturé aussi bien qu’insaturé. Un avantage spécial, c’est que ces techniques peuvent être combinées avec toute technique adéquate dans le puits ou in situ. L’addition d’éléments nutritifs et/ou d’accepteurs d’électrons pour stimuler les processus de dégradation biologique est même possible. Cet article traite de différentes techniques d’assainissement, des résultats numériques de l’ampleur de l’influence et du comportement du temps du système, et la validation de ces résultats d’après des expériences dans le cadre d’un site de recherche contaminé.
