PROBLEM TO BE SOLVED: To provide livestock farming environment maintenance equipment flexibly corresponding with a generation scale of malodorous substances in a livestock barn whose opening is sealed, keeping at a low cost a sanitary state in the livestock barn by carrying out malodorous substances from the livestock barn and ventilating the livestock barn while preventing odor from diffusing to the outside, and capable of performing maintenance and management of the equipment at a low cost.SOLUTION: Livestock farming environment management equipment 10 includes: a malodorous substance processing device 13 which carries out malodorous substances of domestic animal origin, generated in a livestock barn 11 whose opening is sealed, to the outside of the livestock barn 11 while preventing odor from diffusing, and pools the substances； a circulation type air cleaning device 15 which takes out a part of inside air in the livestock barn 11 to the outside of the livestock barn 11, and performs deodorization treatment using a first photocatalyst 14 activated by sunlight to return to the livestock barn 11 as purified air； and a ventilation device 17 which takes out a different part of inside air in the livestock barn 11 while sucking open air taken out from the outside of the livestock barn 11 into the livestock barn 11, and performs deodorization treatment using a second photocatalyst 16 activated by sunlight so as to discharge to the outside of the livestock barn 11.SELECTED DRAWING: Figure 2【課題】開口部を密閉した畜舎内における悪臭物の発生規模に柔軟に対応して、外部への悪臭の拡散を防止しながら畜舎内からの悪臭物の搬出及び畜舎内の換気を行って畜舎内の衛生状態を低コストで維持すると共に、設備の保守及び管理を低コストで行うことが可能な畜産環境保全設備を提供する。【解決手段】畜産環境保全設備１０は、開口部を密閉した畜舎１１内で発生した家畜起源の悪臭物を、悪臭の拡散を防止しながら畜舎１１の外部に搬出して貯留する悪臭物処理装置１３と、畜舎１１内の内部空気の一部を畜舎１１の外部に取出し、太陽光で活性化する第１の光触媒１４を用いて脱臭処理を行って浄化空気として畜舎１１内に戻す循環式空気清浄装置１５と、畜舎１１の外部から取込んだ外気を畜舎１１内に吹込みながら、畜舎１１内の内部空気の別の一部を取出し、太陽光で活性化する第２の光触媒１６を用いて脱臭処理して畜舎１１の外部に放出する換気装置１７とを有する。【選択図】図２
