摘要
Provided are an animal pen, an odor reduction system therefor, etc., with which manufacturing costs and installation costs can be reduced. The odor reduction system (1) comprises: an animal pen (2) having a floor (3) through which the excreta of livestock can drop, and a water storage part (4) which is formed under the floor and stores water used to reduce the odor of the received excreta that has dropped; an aeration tank (21) which aerates water mixed with excreta discharged from the water storage part (4); a precipitation tank (31) in which aeration-treated sludge that has been aerated in the aeration tank (21) is separated by precipitation; and a ring flow passage (41) for circulating the supernatant from the precipitation tank (31) to the water storage part (4).
