| 摘要 |
<p>The present invention relates to an apparatus for filtering pollutant gas, which purifies pollutant gas including volatile organic compounds (VOCs) using microorganisms by fixing the microorganisms on a rotating cylinder where water and nutrients are supplied. The apparatus comprises a pipe which supplies and discharges pollutant gas including VOCs; a filtering part which stores treatment water in a closed inner space, has a microorganism cylinder, in which microorganisms are fixed, on the outer circumference of a shaft pipe connected with the pipe, receives pollutant gas from the pipe and allows the pollutant gas to pass through the microorganism cylinder to filter the pollutant gas; and a control part which controls gas flow in the pipe and rotates the cylinder in the filtering part.</p> |
