Provided is a method for producing cement clinker using an organic sludge is dried by fermentation heat, it provides methods which may be treated suitably odor gas generated by fermentation.
A firing step is the production of cement clinker by firing raw materials A cement clinker. The dried organic sludge obtained by fermenting organic sludge charged into the firing step. Odor gas generated by fermentation of organic sludge, to reduce the odor intensity of the odor gas by passing the odor processing unit 30 including at least one of wood waste and soil. At least one of wood chips and soil containing odor components contained in the odorous gas is charged into the firing step. Preferably, it is desirable to ferment organic sludge by aerobic bacteria, it is desirable that the wood waste containing odor components contained in the odorous gas comprising the step of mixing with an organic sludge.
