Abstract (en)
[origin: EP3574812A1] The present invention aims for providing an excrement treatment device capable of directly discharging sewage in a sewage tank to the outside sewers by a compressed air supplied from the excrement treatment device. The present invention includes a step of opening a suction port of a suction valve 44 of a sewage tank 19 and closing a water discharge valve 46 of the sewage tank 19; a step of sucking air in the sewage tank 19 from an air inlet/outlet 45 of the sewage tank 19 and sucking a sewage from a pipe connected to a suction port of the suction valve 44 to store the sewage; a step of closing the suction port of the suction valve 44 of the sewage tank 19 and opening the water discharge valve 46 of the sewage tank 19; and a step of injecting a compressed air into the air inlet/outlet of the sewage tank 19 to discharge the stored sewage to an outside from the water discharge valve 46.
