Process for gassing a plant for anaerobic and / or aerobic microbial degradation and conversion of organic waste to digestate and / or compost, as well as the associated plant

摘要

The present invention relates to a process for supplying gas to a plant (10) according to the invention for the anaerobic and/or aerobic microbial degradation and conversion of organic wastes to form fermentation residue and/or compost. By oxygen being generated directly on site in an air separation plant (1), advantageously, each time the correct mixture can be generated of oxygen (O2)-enriched air which is required according to, for example, acceleration of composting in a composting system (12), control purposes of the plant (10), for blowing free gas-supply lines (13, 14) or the like. By means of nitrogen (N2) also generated by the air separation plant (1) being utilized in particular for rendering a fermentation system (11) inert, advantageously, the air separation plant (1) is utilized optimally and, in particular, the otherwise necessary extraction of the air or the rotting gases from the fermentation system (11) is reduced. The present invention is equally suitable for the fermentation and composting of organic wastes which can also take place in a joint system. In addition, it is suitable, in particular, for sewage sludge processing, biological residual refuse treatment, biological decontamination of polluted soil, storage of quality soils prior to bagging and aeration of agricultural goods.
