As shown in fig. 1-4, the embodiment provides an ultrahigh speed integrated device for sewage treatment, including a contact tank 14, a coagulation tank 1, a flocculation tank 2 and a sedimentation tank 3, the contact tank 14 is connected with the coagulation tank 1, the coagulation tank 1 is connected with the flocculation tank 2, a first baffle 13 is arranged between the coagulation tank 1 and the flocculation tank 2, the flocculation tank 2 is connected with the sedimentation tank 3, a second baffle 23 is arranged between the sedimentation tank 3 and the flocculation tank 2, one side of the contact tank 14 is connected with a water inlet pipe 12, one side of the sedimentation tank 3 is connected with a water outlet pipe 37, a clear water collection component, a sedimentation component and a sludge transmission component are arranged in the sedimentation tank 3, the clear water collection component includes a water outlet weir 31 and a total water collecting tank 32, the sedimentation component includes an inclined plate 33, and the sludge transmission component includes a spiral sludge scraper. The total water collecting tank 32 is fixed on the inner wall of the sedimentation tank 3, the water outlet pipe 37 is communicated with the total water collecting tank 32, more than two water outlet weirs 31 are arranged in the sedimentation tank 3 in parallel, the tail end of each water outlet weir 31 is communicated with the total water collecting tank 32, more than two inclined plates 33 are stacked in parallel to form a water passing group, and the water passing group is arranged below the water outlet weirs 31. The spiral mud scraper comprises a motor 35 and a screw 34, the screw 34 is positioned below the water passing unit, and a power shaft of the motor 35 penetrates through the wall of the sedimentation tank 3 and is fixedly connected with the screw 34.

The sewage is discharged into a contact tank 14 through a water inlet pipe 12, and a coagulant is put into the coagulation tank 1. The turbidity material in the sewage is negatively charged natural particles which repel each other to form a highly stable state. After the coagulant is mixed, the sewage enters the flocculation tank 2 through the first baffle 13, and the micro-sand is added into the flocculation tank 2. The micro sand is added into the sewage to accelerate flocculation. The sewage after passing through the flocculation tank 2 enters a sedimentation tank 3 for sedimentation. After entering the sedimentation tank 3, the sewage passes through a plurality of inclined plates 33 of the water passing group. The sewage flows up to the effluent weir 31 through the inclined plate 33, flows into the effluent weir 31 through the effluent weir 31, then flows into the total water collecting tank 32 through the effluent weir 31, and flows out through the water storage pipe. The formed particle floc is deposited on the inclined plate 33 and slides down under the action of gravity. Eventually a large amount of flocs settle at the bottom of the settling tank 3. At the same time, the motor 35 is started, and the motor 35 drives the screw 34 to rotate. And screw rod 34 sets up in the position that is close to sedimentation tank 3 bottom, and the silt and the floc of gathering in sedimentation tank 3 bottom are shifted towards sedimentation tank 3 one side to pivoted screw rod 34, and silt and floc shift one side and can vacate sedimentation tank 3 bottom to follow-up floc subsides with silt. The silt moved to one side can be more conveniently transported away through the collecting device.

The spiral mud scraper in this embodiment adopts above-mentioned setting, has avoided holing from swash plate 33 and has passed, makes swash plate 33 can keep original intensity, and each swash plate 33 all can cross water, improves swash plate 33's utilization ratio. Meanwhile, compared with the traditional central spiral mud scraper, the screw 34 type spiral mud scraper has the characteristic of large torque, and the mud scraper can not be started again after being stopped, so that the mud in the sedimentation tank 3 can not obstruct the start of the spiral mud scraper. Meanwhile, mud is more uniformly stored among each section of blades on the screw 34, and a better mud scraping and conveying effect can be obtained. The conventional central type spiral mud scraper has to design the sedimentation tank 3 to be square, thereby limiting the area of the inclined plate 33 and further influencing the water passing effect. The spiral type spiral mud scraper adopted by the embodiment has no shape limitation, so that a larger inclined plate 33 area can be realized, and a better inclined plate 33 sedimentation effect is realized.

Concretely, the ultrahigh-speed integrated equipment for sewage treatment further comprises a reflux pump 41, a first reflux pipe 42, a second reflux pipe 44 and a separator 45, wherein the reflux pump 41 is communicated with the sedimentation tank 3 through the first reflux pipe 42, the reflux pump 41 is connected with the separator 45 through the second reflux pipe 44, and the separator 45 is arranged above the flocculation tank 2.

Through a second return conduit 44 to a separator 45. The separator 45 in this embodiment is a hydrocyclone. After entering the hydrocyclone, the micro sand is separated from the sludge, the micro sand enters the flocculation tank 2 to participate in the flocculation of the sewage again, and the sludge is discharged to the next environmental protection treatment step for treatment after being separated.

Specifically, the first return pipe 42 is provided with a valve 43. At the beginning of sedimentation, the sediment settled in the sedimentation tank 3 is not much, and at this time, if the reflux pump 41 is started to suck the sediment, the efficiency is not high. At this time, the valve 43 is also closed to prevent the entrance of silt.

Specifically, the connection of the first return pipe 42 to the sedimentation tank 3 is located below the connection of the screw 34 to the sedimentation tank 3.
