<p>PROBLEM TO BE SOLVED: To provide a method for treating gas by which exhaust gas containing organic gas such as gas of an organic solvent is decomposed efficiently, easily and at low cost and removed by the other method. SOLUTION: Ascending gas 2 to be treated and descending gas-treating liquid 1 are subjected to gas-liquid contact with each other in the inside of a gas treatment tower. In this case, a part (branch gas) 3' of the gas to be treated is preliminarily mixed with the gas treatment liquid 1 and is supplied to the gas treatment tower 5. After gas-liquid contact in the inside of the tower, a gas component dissolved in the treatment liquid is decomposed or removed preferably by using a microbiological treatment method. Thereby, the gas to be treated can be extremely efficiently treated.</p> |
