Zusammenfassung:	A ventilation system of a sludge receiving facility capable of efficiently preventing gases such as odor from stagnating in a sludge tank and a structure covering the sludge tank by a small capacity ventilation means by selectively and carefully ventilating odorous places during normal operation and each time when sludge is received. In the sludge receiving facility, upper and lower structures (11, 12) communicating with an internal space (19) are constructed, entrances (13) having opening/closing means (14) are formed in the wall part of the upper structure (12), sludge tanks (15a, 15b) having sludge charging ports (17) are installed in the lower structure (11), and partition walls (21) are formed to partition loading spaces (22) in the upper structure from the internal space (19). The sludge receiving facility comprises an outside air blowing means (30) continuously blowing the outside air from the bottom part of the lower structure to the internal space, air flowing means (33) allowing the internal space to communicate with the loading spaces, first discharging means (35) discharging the air from the upper parts of the loading spaces, second discharging means (36) discharging the air on the upper sides of the sludge charging ports, and third discharging means (37a, 37b) discharging the air inside the sludge tanks. Furthermore, opening/closing means (33, 40, 41, 42a, 42b) are installed in the flowing means and first to third discharging means. La présente invention concerne un système de ventilation d'une installation réceptrice de boues capable d'empêcher efficacement la stagnation de gaz, telles des odeurs, dans un réservoir de boues et une structure couvrant le réservoir de boues à l'aide d'un dispositif de ventilation à faible capacité en aérant sélectivement et soigneusement des emplacements mal odorant au cours d'une opération normale et à chaque arrivée de boues. Dans l'installation réceptrice de boues, des structures supérieure et inférieure (11, 12) communiquant avec un espace interne (19) sont construites, des entrées (13) dotées d'un dispositif d'ouverture/fermeture (14) sont formées dans la partie paroi de la structure supérieure (12), des réservoirs de boues (15a, 15b) dotés d'orifices de chargement de boues (17) sont installés dans la structure inférieure (11) et des parois de séparation (21) sont formées afin de séparer des espaces de chargement (22), présents dans la structure supérieure, de l'espace interne (19). L'installation réceptric
