As shown in fig. 2, the utility model is applicable to a siphon drainage device in a waste water station, and comprises a siphon ascending pipe 8, a siphon descending pipe 9, a siphon auxiliary pipe 3, an exhaust pipe 4 and a siphon breaking pipe 5; one end of the siphon ascending pipe 8 is communicated with the drain pipe 7 which is both communicated with the pool 12, the other end of the siphon ascending pipe 8 is communicated with the siphon descending pipe 9, a U-shaped bent pipe 13 (inverted U-shaped bent pipe) with a downward opening is spliced at the joint of the siphon ascending pipe 8 and the siphon descending pipe 9, one end of the siphon auxiliary pipe 3 is connected to the pipe top of the inverted U-shaped bent pipe 13, and the other end of the siphon auxiliary pipe 3 is simultaneously communicated with the exhaust pipe 4, the siphon breaking pipe 5 and the emergency siphon breaking pipe 6; the exhaust pipe 4 is connected with an external cleaning vacuum system (self-contained in a factory of the waste water station), and an exhaust electromagnetic valve 41, a vacuum sensor 42 and a drainer 43 are arranged on the exhaust pipe 4; the tail end of the siphon breaking pipe 5 is provided with a siphon breaking bucket 52, the siphon breaking bucket 52 is arranged at the lowest water level of the pool, and the siphon breaking pipe 5 is also provided with a normally open ball valve I51; the emergency siphon break pipe 6 is provided with a normally closed ball valve II61; the siphon down pipe 9 is communicated with a water inlet pipe 10 of a reaction tank or a regulating tank 14, and a liquid level valve 101 and a block valve 102 are arranged on the water inlet pipe 10. A breather valve 1 and a liquid level sensor I2 are also arranged in the tank 12.
The inner diameters of the siphon auxiliary pipe 3, the exhaust pipe 4 and the siphon breaking pipe 5 are basically consistent, the inner diameters of the siphon rising pipe 8 and the siphon falling pipe 9 are consistent, and the inner diameter of the siphon auxiliary pipe 3 is 1/100 of the inner diameter of the siphon rising pipe 8.
Wherein, the height of the water outlet of the water inlet pipe 10 is lower than the height at the vertex of the inverted U-shaped bent pipe, and the height refers to the height relative to the same horizontal plane (ground), so that the water is pumped to the U-shaped bent pipe 13 by vacuumizing, and the water at the U-shaped bent pipe 13 automatically flows into the reaction tank or the regulating tank 14 through the water inlet pipe 10 based on the siphon principle.
As shown in fig. 3, the siphon break bucket 52 includes a bucket body 521 and a communicating pipe 522 fixed to the bucket body 521 for communicating the bucket interior chamber with the outside of the bucket body; the bucket 521 is fixed on the siphon break pipe 5 through a connecting frame 523; communication pipe 522 is an inverted U-shaped pipe, and the height of the end opening of siphon break pipe 5 is not lower than the height of the opening of communication pipe 522, where the height refers to the height relative to the same horizontal plane (both the pool bottom plane).
When the siphon breaking pipe 5 sucks water stored in the siphon breaking bucket 52, the interval time for refilling the water stored in the water bucket body 521 after being pumped out directly influences the siphon breaking degree, and when the water level in the tank 12 is lowered below the edge of the siphon breaking bucket 52, the waste water in the tank can still flow into the siphon breaking bucket 52 through the small siphons (communicating pipes 522) at the two sides. When the liquid level in the tank 12 is reduced to the lowest level, namely the wastewater level outside the siphon break bucket body 521 is reduced below the small siphon pipe orifice, the siphon break bucket 52 stops water inflow; after the siphon break pipe 5 evacuates the water stored in the bucket body 521 quickly, the pipe orifice of the siphon break pipe 5 exposes the air inlet, the siphon ascending pipe 8 stops draining, and the water level of the wastewater in the pool begins to rise.

When the liquid level in the drainer 43) rises, the liquid level sensor II432 detects that the highest water level is reached, the electromagnetic valve 433 is opened, the waste water in the drainer 43 is discharged, and when the liquid level sensor II432 detects that the liquid level is lowered to the lowest water level, the electromagnetic valve 433 is closed, and the vacuum degree is prevented from being damaged after the waste water is discharged completely.
