     the motive for this work was the biological cleansing of waste air, especially the cleansing of nox and co.the carboxydotrophic culture was enriched in laboratory reactors. trickling filters were chosen as biological cleansing reactors.the enrichment in the reactors was carried out under continuous exposure to co and no gas and semicontinuous exposure to a nutrient medium.the micro-organisms adhere to the rough surface of the leca stones. then they catalyse the oxidation no.the adjustment of the concentration of waste air is carried out with compressed air. the analytic control of gaseous components is carried out at the inlet and the outlet of the reactor.the metabolic creation is controlled through circulated water. the inoculation of the trickling filter is carried out with actively overgrown leca stones.a co elimination rate of 99% was reached, but the no elimination rate did not cross more than 7%. to improve this result i used different bioreactors such pressure reactor in the laboratory.the filter volumes were at about 1,5 till 3 liters.by using the pressure reactor i was able to achieve the best result for the no elimination rate of 33 % in this research project.
