(111) after flowing into the first inverting chamber (11), operation first piston (41) moves extruding dirt to the direction coarse filtration net unit (31A)
Water, then the sewage in the first inverting chamber (11) passes through coarse filtration net unit (31A) inflow the first transfer chamber (12) under pressure
The interior primary filtering of completion, under the biggish solid particle of partial size is intercepted by coarse filtration net unit (31A) in the process；
It moves strainer band (3) again at this time, keeps 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 second bottom in moving process fine filtering net unit (31C) is left pedestal (13), and second is thin
Remaining sewage is fallen into together with the larger solid particle being blocked in the recovery pond of lower section 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) flows back in the first inverting chamber (11) under differential pressure action by the first fine filtering net unit (31B)
Secondary filter is completed, and under some residual solid particle in sewage is then intercepted by the first fine filtering net unit (31B)；First exchange
Twice-filtered sewage is discharged into progress next procedure processing in conditioning tank by the first outlet pipe (112) in chamber (11)；And
While first piston (41) bounces back, the sewage in sump is flowed into the second inverting chamber (21) by the second water inlet pipe (211), behaviour
Make second piston (42) and move extruding sewage to the direction coarse filtration net unit (31A), then the sewage in the second inverting chamber (21) is being pressed
Lower flow into the second transfer chamber (22) by coarse filtration net unit (31A) of power effect completes primary filtering, in the process partial size compared with
Under big solid particle is intercepted by coarse filtration net unit (31A)；
Strainer band (3) are then moved again, keep coarse filtration net unit (31A) corresponding with the first cavity (1), the second fine filtering net unit
(31C) is corresponding with the second cavity (2)；It operates second piston (42) retraction and carries out secondary filter；Operate first piston (41) again
Extruding once filtered, so repeat the above process can to the sewage in sump simultaneously progress once, secondary filter.
