The exhaust pipe 8 for discharging the malodorous gas generated from the flat poultry house 1 and the chicken manure deodorizing device A for biologically treating the exhaust W discharged from the exhaust pipe 8 are formed in the central portion of the above.

This chicken manure deodorizing apparatus A is a system which is processed by the constitution as shown in the flow chart of FIG. First, the poultry manure generated in the Heike poultry house is fed into each receiving pit, and the poultry manure in each receiving pit is put into a mixing tank and mixed. The poultry manure mixed in the mixing tank is quantitatively measured, transported to a supply facility, and further charged into a carbonization device. A part of the bad odor of the chicken feces carried to the carbonization device is exhausted through the steam of the waste heat boiler, and most of the bad odor causes the fermentation liquor carried to the cooling conveyor to be further sent to the carbide hopper to be a char. The fermented liquor at that time is the fermented liquid fed from the undiluted liquid preparation tank in the fermenter, while the fermented liquid fermented from the fermenter is sent to the desulfurization facility and the digested sludge storage tank. The fermented liquor sent to the desulfurization facility is partially burned in the combustion tower via the gas holder, but most of it is converted to electric energy in the power generation facility. On the other hand, the fermentation liquor in the digested sludge storage tank is sent to a dehydrator equipped with chemical injection equipment, and part of it is transported to the drainage storage tank and discharged, but most of it is sent to the dryer via the dehydrated cake hopper.

By adopting such a malodorous deodorizing method, it becomes possible to independently perform energy conversion other than the deodorizing effect. Especially in recent Japan, research on biogasification of chicken feces alone has been advanced. For example, it is important to use clean natural and unused energy that does not rely on fossil energy to reduce CO2 for the purpose of suppressing global warming. Chicken manure, which is currently a problem, is methane gasified into light energy and heat energy. Converting is being studied in various pledge test laboratories. That is,
