BIOLOGICAL TREATMENT OF DIGESTION GAS

摘要

PURPOSE:To biologically perform treatment of digestion gas without using chemicals. CONSTITUTION:A packed layer 2 is formed by packing a filler to which microorganisms adhere in the inside of a treatment vessel 1. Digestion gas is introduced into the treatment vessel 1 and brought into contact with absorption liquid circulated to an aeration tank. Hydrogen sulfide and gaseous carbon dioxide contained in the gas are absorbed in the absorption liquid. While the absorption liquid flows down through the inside of the packed layer, the same is decomposed by microorganisms. Gaseous hydrogen sulfide component discharged from the aeration tank is biologically treated in the other treatment vessel 9.
