PROBLEM TO BE SOLVED: To perform stable operation regardless of change of air temperature.SOLUTION: An anaerobic treatment apparatus 100 has a configuration in which a flow rate of organic waste water to a first treatment part 11 and a second treatment part 12 is controlled by control means 9. Hereby, for example, when temperature of the organic waste water lowers due to air temperature change, the flow rate of the organic waste water to the second treatment part 12 in which anaerobic treatment is performed in a middle temperature condition is increased while sludge in the first treatment part 11 is acclimatized in a low temperature condition, thereby the acclimatization to a low temperature condition can be performed without delaying normal operation, and stable operation as the energy-saving anaerobic treatment apparatus can be achieved. |
