用于操作用于废水的压力排水系统的方法
摘要：
本发明涉及一种用于操作用于废水的压力排水系统(1)的方法，压力排水系统具有相互连接的路段(SA1...SA9)用于传导废水到传送站(10)，和多个与路段相连接的泵站(2)，用于收集废水，至少一部分泵站(2)的每个泵站至少发送一个它抽送准备就绪状态的指示信息到中央控制单元(3)，然后从具有抽送准备就绪状态的泵站(2)中，针对路段中的一个路段形成这样的一组，组的泵站(2)的数量至少相应于路段中的一个路段的泵站(2)最小数量(p_min)，随后通过中央控制单元(3)同时起动所述组的泵站(2)。由此实现了在压力排水系统的大部分区域和在最大时间段里存在着一个最小流速，最小流速起到一个清洁效果，从而降低了堵塞的风险。
摘要（英）：

The invention relates to a method of operating a pressurized wastewater-drainage system (1) having interconnected line sections (SA1 . . . SA9) for conducting wastewater to a transfer station (10) and a plurality of pump stations (2) connected to the line sections (SA1 . . . SA9) for collecting the wastewater, wherein at least a portion of the pump stations (2) transmits at least status information indicating its respective pump standby status to a central controller (3), wherein a group is formed from the set of pump stations (2) that are in pump standby in relation to one of the line sections (SA1 . . . SA9) such that the number of pump stations (2) of the group corresponds at least to a minimum number (p_min) of pump stations (2) associated with this line section (SA1 . . . SA9), and the pump station (2) or pump stations (2) of the group are then activated simultaneously by the central controller (3). A minimum flow rate is thus present in wide portions of the pressurized drainage system and for a maximum time, which results in a cleaning effect and thus reduces the danger of clogging.
