A trigger rod (37) is fixedly connected to the right side of the linkage wheel (28) near the edge, and a trigger block (35) is fixedly connected to the left side of the hinged plate (25) on the right side.

10. The method for using the microbial petroleum decontamination wastewater treatment device according to any one of claims 1 to 9, characterized in that: The following steps are involved: S1: When the refinery wastewater enters the oil separator (1) through the pump body, the motor (19) can be started first to drive the meshing gear (24) to rotate. When the meshing gear (24) rotates, it can mesh with the tooth block inside the annular plate (20), thereby driving the annular plate (20) to move along the annular groove. When the annular plate (20) drives the reciprocating plate (8) to move synchronously, when the reciprocating plate (8) moves, it can drive the discharge box (21) to move through the connecting plate (22), thereby realizing the addition of microorganisms inside the oil separator (1); S2: When the timing motor (26) is started, the driving gear (36) can be driven to rotate through the power output shaft. When the power output shaft rotates, the rotating plate (44) can be driven to rotate. When the rotating plate (44) rotates, the sliding rod (38) can be driven to move. When the sliding rod (38) rotates, it can be engaged with the guide groove to drive the rotating wheel (27) to rotate intermittently. When the rotating wheel (27) rotates, it can drive a plurality of second engaging rods (42) to rotate. When the second engaging rods (42) rotate, they can drive the linkage gear (31) located on the left side to mesh. S3: When the linkage gear (31) on the left side rotates, the linkage wheel (28) on the left side can be driven to rotate through the adjacent third fitting rod (43); when the linkage wheel (28) on the left side rotates, the linkage gear (31) on the right side can be driven to rotate; when the linkage wheel (28) rotates, a timing function can be realized, thereby facilitating gravity separation of oil and water; S4: When the linkage wheel (28) on the right side rotates, it can drive the trigger rod (37) to start the trigger block (35). When the trigger block (35) is triggered, the electric pole (40) can be started. The electric pole (40) can drive the rack (6) to move downward through the power output shaft, thereby meshing with the gear (11). When the reciprocating plate (8) moves, it can drive the connecting plate (22) to move, thereby causing the guide plate (17) to move. Since the movable plate (5) is slidably connected to the positioning plate (4), when the positioning plate (4) moves forward and backward When the gear (11) moves back and forth, the rack (6) can drive the gear (11) to rotate. When the gear (11) rotates, the second rotating shaft can drive the driving groove wheel (12) to rotate. When the driving groove wheel (12) rotates, the belt (13) can drive the driven groove wheel (14) to rotate. When the driven groove wheel (14) rotates, the first rotating shaft can drive the winding wheel (15) to rotate. When the winding wheel (15) rotates, the pull rope (9) can be pulled to drive the scraper (2) to move forward, thereby cleaning the grease on the surface of the inclined plate (41).
