Abstract

- A location contaminated with mineral oil was tested for the possibility of a bioremediation; - the microbiological tests showed, that there is both an aerobiotic and an optional anaerobic autochthonous pollutants degrading microflora but only the activation of the aerobiotic germs was possible by both suitable nutrients and test conditions; - in degrading tests with a high concentration of pollutants a degradation was possible by addition of different nutrients. Within a week a degradation of about 70% was shown. In areas of lower concentration the possible degradation was smaller. - An in-situ-rehabilitation by a hydraulic supply of the soil microorganisms was not possible because of the anisotropic conditions at the location in a depth of 5-10 m; - an in-situ-rehabilitation with both soil air aspiration and aeration, for the supply of the soil microorganisms too, is even possible at anisotropic soil conditions; - now there is knowledge about both a variable filtration and tubing for an optimal adaptation for the bioremediation to the damage; - apparatus were developped for in-situ-rehabilitation for small and medium locations, useable for biological processes too; - there is a wide utilization of the aeration apparatus is because of the careful environmental use.

(orig.) [Deutsch] - Ein Mineraloel-kontaminierter Altlaststandort wurde im Hinblick auf eine moegliche biologische Sanierung untersucht. - Die mikrobiologischen Untersuchungen ergaben, dass eine aerobe und fakultativ anaerobe autochthone schadstoffabbauende Mikroflora vorhanden ist, aber nur der aeroben Keime durch geeignete Naehrstoffe und Versuchsbedingungen aktivierbar waren. - In Abbauuntersuchungen durch Zusatz unterschiedlicher Naehrsalze konnte bei hoher Schadstoffkonzentration schon nach 1 Woche ein Abbau > 70% erreicht werden. In niederen Konzentrationsbereichen war die Schadstoffabbaupotenz wesentlich geringer. - Die anisotropen Verhaeltnisse am Standort in 5-10m Tiefe liessen eine In-situ-Bodensanierung ueber eine hydraulische Versorgung der Boden-Mikroorganismen nicht zu. - Eine In-situ-Bodensanierung ueber Bodenluftabsaugung und Belueftung, auch zur Versorgung der Boden-Mikroorganismen, ist selbst unter stark anisotropen Bodenverhaeltnissen durchfuehrbar. - Es wurden Erkenntnisse zur variablen Verfilterung und Verrohrung und somit zur optimalen Anpassung der Sanierung an den Schadensfall gewonnen. - Es wurden Geraete fuer die In-situ-Sanierung kleiner und mittlerer Standorte entwickelt, die auch fuer biologische Verfahren anwendbar sind. - Die Verwertbarkeit des Belueftungsgeraetes ist auf Grund der umweltsicheren Nutzungsmoeglichkeit gross.
