Carrier for anaerobic treatment, anaerobic treatment apparatus and anaerobic treatment method

摘要

To provide an anaerobic treatment carrier, an anaerobic treatment apparatus, and an anaerobic treatment method for efficiently treating methanol by using a pathway for direct methane fermentation of methanol in anaerobic treatment of methanol-containing wastewater.SOLUTION: In the treatment of methanol-containing wastewater, the anaerobic treatment is performed by causing a methane fermentation tank to have a carrier in which methane fermenting bacteria directly using methanol is present on the surface and/or inside without passing through acetic acid or formic acid.SELECTED DRAWING: Figure 1
