Abstract
A process is disclosed for purifying and treating polluted materials by means of micro-organisms. Sludge that contains both micro-organisms that decompose the impurities contained in the polluted materials and the nutrients required by said micro-organisms is added to the polluted materials. The mixture of polluted materials and sludge keeps its shape and its humidity content does not exceed a limit value dependent on the nature of the soil and sludge.
Claims
1. Verfahren zur Reinigung und Aufbereitung von verunreinigtem1. Process for the purification and treatment of contaminated
Gut mittels Mikroorganismen, bei welchem das verunreinigte Gut, die Verunreinigung abbauende Mikroorganismen und erforderlichenfalls Nährstoffe für die Mikroorganismen in einen Behandlungsraum oder in eine Behandlungsfläche eingebracht werden und dort so lange verbleiben, bis der gewünschte Dekontaminierungsgrad erreicht ist, dadurch gekennzeichnet,Good by means of microorganisms, in which the contaminated material, the pollution-degrading microorganisms and, if necessary, nutrients for the microorganisms are introduced into a treatment room or in a treatment area and remain there until the desired degree of decontamination is achieved, characterized
- daß dem verunreinigten Gut Schlämme zugefügt werden, die die Verunreinigungen abbauende Mikroorganismen enthalten, daß die Schlämme außerdem die Nährstoffe für die Mikroorganismen enthalten,that sludge is added to the contaminated material, containing the microorganisms degrading the impurities, that the sludge also contains the nutrients for the microorganisms,
- daß das verunreinigte Gut mit den Schlämmen vermischt wird,- that the contaminated material is mixed with the sludges,
- daß die Konsistenz des Gemischs aus verunreinigtem Gut und Schlämmen formerhaltend ist,- that the consistency of the mixture of contaminated material and sludge is form-retaining,
- daß der Feuchtigkeitsgehalt des Gemischs einen von der Boden- und Schlammbeschaffenheit abhängigen Grenzwert nicht überschreitet,- that the moisture content of the mixture does not exceed a limit dependent on soil and sludge characteristics,
- daß das Gemisch zu einer Miete aufgebaut wird. - That the mixture is built up for rent.
