<p>A method for purging a bio-film in an anaerobic reactor, which improves efficiency of the anaerobic reactor, increases an amount of bio-gas generated, and reduces load of an aerobic treatment tank that is a secondary treatment tank, is provided. A method for purging a bio-film in an anaerobic reactor comprises: a first step of installing an anaerobic reactor(110) having a bio-film adhered to an inner part thereof to treat harmful wastewater containing microorganisms, and opening a drain valve to drop a level of wastewater stored in the anaerobic reactor; a second step of primarily purging microorganisms plugged between layers of the bio-film by flowing in N2 through a collector pipe(111) which is installed within the anaerobic reactor, and on which plural nozzle pipes(112) are formed; and a third step of secondly purging microorganisms by circulating wastewater through a recycle pump(120) after performing the second step.</p> |
