摘要: Disclosed is a sewer system including a sewage receptacle, sewer piping connected to the sewage receptacle by means of a discharge valve, a mechanism for generating vacuum in the sewer piping, and a control mechanism for controlling the discharge valve. In order to achieve a more rapid closing of the discharge valve after discharge of the sewage from the sewage receptacle, the vacuum sewer system further comprises an aeration device in direct fluid communication with the discharge valve. The control mechanism is arranged to control the aeration device. Also disclosed is a discharge valve (2) for such a vacuum sewer system.
