Abstract: Chemical-biological purification of waste gases (2), comprises determining the chemical composition and quantity of compounds present in the exhaust gases as incurred emissions, dismantling at least one reaction chamber (4) of a bioreactor (3), which comprises at least one type of microorganisms for degradation of the organic compounds on an inert carrier material with a biofilm, humidifying the inert carrier material and the biofilm by at least one moistening device (5) having an aqueous treatment liquid, which is added into a fermenter with the microorganisms and nutrients. Chemical-biological purification of waste gases (2), comprises determining the chemical composition and quantity of compounds present in the exhaust gases as incurred emissions, dismantling at least one reaction chamber (4) of a bioreactor (3), which comprises at least one type of microorganisms for degradation of the organic compounds on an inert carrier material with a biofilm, humidifying the inert carrier material and the biofilm by at least one moistening device (5) having an aqueous treatment liquid, which is added into a fermenter with the microorganisms and nutrients, and which is collected in a collecting chamber after sifting in reaction chamber and fed from collecting chamber to the moistening device for recirculation. The treatment liquid is guided through the fermenter during the recirculation, where each of the nutrients is dosed separately according to the chemical composition and amount of compounds in the exhaust gas the fermenter. Independent claims are also included for: (1) a bioreactor for the chemical and biological purification of waste gases, comprising at least one reaction chamber, in which compounds in the exhaust gas are degraded, inert carrier material in the reaction chamber, on which a biofilm is located with at least one kind of microorganisms suitable for degradation of organic compounds, at least one moistening device in the reaction chamber, by which the carrier material and the biofilm are moistened with an aqueous treatment liquid, and a collecting chamber, in which the treatment liquid is fed into the reaction chamber for sifting and is collected for the recirculation in a return line, where the reaction chamber is divided into at least two chambers, through which exhaust gas can flow successively, and which are connected with each other by the collecting chamber; and (2) a system (1) for chemical and biological purification of waste gases, comprising a detection device for determining the chemical composition and quantity of compounds present in the exhaust gases as incurred emissions, bioreactor, the return line for recirculation of the treatment liquid to the moistening device, and fermenter, in which the aqueous treatment liquid is mixed with the microorganisms and with the nutrients, where the return line is led initially with a first portion into the first fermenter for recirculation of the treatment liquid, and is led with a second portion to moistening device, and a storage container is connected to the fermenter for separate dosing of various nutrients for the microorganisms.
