A method of automatic flushing of a pressure sewage system and system for implementing this method

摘要

The pressure sewer system consisting of the main line (1) and the connections (2) is dimensioned, during the construction, for the nominal flow (Q.sub.j.n.) and the nominal pressure (P.sub.j.n.) of the flowing waste water. During normal use, the instantaneous flow (Q.sub.o.n.) and the instantaneous pressure (P.sub.o.n.) are several times lower, thereby causing the main line (1) to become clogged. The method describes a temporary controlled change of the instantaneous pressure (P.sub.o.n.) and the instantaneous flow (Q.sub.o.n.) of waste water to values close to the nominal pressure (P.sub.j.n.) and to the nominal flow (Q.sub.j.n.) for flushing the main line (1) of the pressure sewage system. The subject of the invention is also the system for making the temporary controlled change of the instantaneous pressure (P.sub.o.n.) and the instantaneous flow (Q.sub.o.n.) of the waste water.
