(111) after flowing into the first inverting chamber (11), operation first piston (41) moves extruding dirt to coarse filtration net unit (31A) direction
Water, then the sewage in the first inverting chamber (11) is under pressure by coarse filtration net unit (31A) the first transfer chamber of inflow (12)
Under interior completion is primary to filter, then larger solid particle of grain size is intercepted by coarse filtration net unit (31A) during this；
It moves strainer band (3) again at this time, makes coarse filtration net unit (31A) corresponding with the second cavity (2), the first fine filtering net unit
(31B) is corresponding with the first cavity (1), and pedestal (13) is left in second fine filtering net unit (31C) bottom in moving process, and second is thin
It is fallen into the recovery pond of lower section together with remaining sewage and the larger solid particle being blocked in filter screen unit (31C)；Operation
First piston (41) bounces back to the direction far from the first fine filtering net unit (31B), makes to form vacuum in the first inverting chamber (11), then
Sewage in first transfer chamber (12) is flowed back to by the first fine filtering net unit (31B) in the first inverting chamber (11) under differential pressure action
Secondary filter is completed, and under some residual solid particle in sewage is then intercepted by the first fine filtering net unit (31B)；First exchanges
Twice-filtered sewage is discharged into progress next procedure processing in regulating reservoir by the first outlet pipe (112) in chamber (11)；And
While first piston (41) bounces back, the sewage in sump is flowed by the second water inlet pipe (211) in the second inverting chamber (21), behaviour
Make second piston (42) and move extruding sewage to coarse filtration net unit (31A) direction, then the sewage in the second inverting chamber (21) is being pressed
Lower flowed into the second transfer chamber (22) by coarse filtration net unit (31A) of power effect completes primary filtering, in the process grain size compared with
Under big solid particle is intercepted by coarse filtration net unit (31A)；
Subsequent strainer band (3) mobile again, makes coarse filtration net unit (31A) corresponding with the first cavity (1), the second fie screen list
First (31C) is corresponding with the second cavity (2)；It operates second piston (42) retraction and carries out secondary filter；Operate first piston (41) again
Secondary extruding is once filtered, and the sewage in sump can be carried out at the same time primary, secondary filter by so repeating the above process.
