PURPOSE: A method for controlling the initial operational condition is provided to maintain the concentration of microorganisms in the anaerobic digestion bath with a pre-determined range. CONSTITUTION: A method for controlling the initial operational condition includes the following: anaerobic digestion sludge or anaerobic microorganisms are injected into a digestion bath(S200). The pure alkali degree and the concentration of NH_4^+-N in the sludge supernatant liquid of the digestion bath is detected(S210). The amount of organic materials is calculated for adjusting the alkali degree and the concentration of NH_4^+-N(S220). The calculated amount of organic carbon source is injected into the digestion bath(S230).
