During sewage treatment, sewage enters the sedimentation tank body 1 from the water inlet device 2, flocculating agents are added into the sewage before entering, when the sewage flows outwards from the middle part, sludge flocculates and precipitates at the bottom of the sedimentation tank body 1, treated water flows out from the water outlet weir, the bottom of the sedimentation tank body 1 inclines, the sludge precipitated at the bottom of the sedimentation tank body 1 is scraped to the inside of the sludge collecting tank 11 by the rotating sludge scraper 3, and the rotating speed of the sludge scraper 3 is slower in order to prevent the precipitated sludge from being stirred up. The deeper the depth, the less the oxygen content, and an anaerobic environment is formed at the position of the sludge collecting groove 11, and the microorganism and bacteria react to release gases, including methane, carbon dioxide, nitrogen and the like, which can cause sludge expansion, so that the gases drive the sludge to float upwards, the sewage treatment is incomplete, and the floating sludge flocculation cannot be settled.
Therefore, in this embodiment, by setting the sludge exhausting device 4, the rotating sludge scraper 3 is utilized to drive the rotating block 41 and the extruding plate 423 to rotate, the extruding plate 423 pushes the sludge, and since the sludge scraper 3 rotates slowly, the sludge is not excited when the extruding plate 423 pushes the sludge, and when the space enclosed by the rotating block 41, the fixing plate 421, the porous plate 422 and the extruding plate 423 becomes smaller, the sludge passes through the porous plate 422 to be extruded and cut, so that the gas is diffused to the water phase, thereby achieving the purpose of releasing the gas in the sludge, and thus, not only the microorganism can decompose the organic matters, but also the problem of floating of the sludge flocculation caused by gas expansion can be prevented.
In this embodiment, as shown in fig. 3-7, the extruding assembly 42 further includes a first guide rail 424 and a second guide rail 425 disposed at the bottom of the sludge collecting tank 11 and located at two sides of the porous plate 422, the first guide rail 424 is disposed at an edge position of the sludge collecting tank 11, one end of the second guide rail 425 is close to the porous plate 422, and the other end is located at an edge position of the sludge collecting tank 11, a pin 4231 capable of sliding along the first guide rail 424 and the second guide rail 425 is fixedly connected to the bottom of the extruding plate 423, when the extruding plate 423 is close to the porous plate 422, the pin 4231 slides in the first guide rail 424, and when the extruding plate 423 is far away from the porous plate 422, the pin 4231 slides in the second guide rail 425. In the process that the mud scraper 3 drives the rotating block 41 to rotate, the pin shaft 4231 at the bottom of the extruding plate 423 slides in the first guide rail 424, so that the extruding plate 423 can push mud, the space surrounded by the rotating block 41, the fixed plate 421, the porous plate 422 and the extruding plate 423 is reduced, and the mud is extruded and cut from the porous plate 422.
Further, the porous plate 422 is composed of a plurality of hole plates 4222 arranged side by side, and holes on adjacent hole plates 4222 are staggered. The effect of the extruded and cut sludge can be improved, and the holes are not too small, so that round holes with diameters of about 4-6 cm or square holes with diameters of about 4-6 cm are generally ensured.
Further, the pressing members 42 are provided with two sets, and one ends of the guide rails 424 and the guide rails 425, which respectively belong to the two sets of pressing members 42, are connected to each other. To increase the efficiency of gas release.
Further, a rotating roller 4221 is rotatably connected to one end of the porous plate 422 near the rotating block 41, and a side slot 411 for accommodating the pressing plate 423 is formed on the outer side of the rotating block 41. When the pressing plate 423 passes over the porous plate 422, the pressing plate 423 is pushed into the side slot 411 by the rotating roller 4221.
Further, an elastic block 412 for pushing the pressing plate 423 in a direction away from the rotating block 41 is mounted on a side wall of the rotating block 41 at the side slot 411. Immediately after the pressing plate 423 passes over the porous plate 422, the elastic block 412 pushes the pressing plate 423 out of the side slot 411 in order to allow the pin shaft 4231 to enter the inside of the guide rail two 425.
Specifically, during operation, the sludge scraper 3 drives the rotating block 41 to rotate, the pin shaft 4231 slides in the first guide rail 424, the extruding plate 423 pushes sludge below the fixed plate 421, when the space surrounded by the rotating block 41, the fixed plate 421, the porous plate 422 and the extruding plate 423 is reduced, the sludge is extruded and cut from the porous plate 422, when the extruding plate 423 passes over the porous plate 422, the sludge is pushed into the side slot 411 by the rotating roller 4221, and when the extruding plate 423 passes over the porous plate 422, the elastic block 412 immediately pushes the extruding plate 423 out of the side slot 411, so that the pin shaft 4231 can enter the second guide rail 425.
Example two
In the first embodiment, although the sludge scraper 3 moves relatively slowly, the sludge flocculation tends to be reduced when the sludge is squeezed and slit, this part does not float up, and only a very small part of the sludge forms colloids which are bound to the flocculant when they are precipitated before, so that other chemical agents such as surfactants can be added to precipitate the sludge by different mechanisms in order to precipitate it again.
Accordingly, referring to fig. 1 to 9 of the drawings, in the first embodiment, the lower portion of the fixing plate 421 is divided into the pressing region 43 and the buffer region 44 by the porous plate 422, and the pressing plate 423 rotates from the pressing region 43 to the buffer region 44. The sludge treatment device 5 is further provided with a sludge wrapping device, a sludge inlet 13 is formed in the position of the sludge collecting groove 11, which is located in the extrusion area 43, a sludge outlet 12 is formed in the position of the sludge collecting groove 11, which is located in the buffer area 44, the sludge treatment device 5 comprises a sludge pump 51, an inlet of the sludge pump 51 is communicated with the sludge outlet 12, an outlet of the sludge pump 51 is communicated with the sludge inlet 13, and a feeding device 52 is communicated at the inlet position of the sludge pump 51. Even if the sludge pump 51 is used to circulate the sludge at the sludge inlet 13 and the sludge outlet 12, chemical agents such as surfactants are added during circulation, and after the surfactants enter the sludge collection tank 11, the surfactants are mixed with the colloid to precipitate the sludge, and it should be noted that the amount of the added surfactant is not too large because the amount of the generated colloid is very small, and the sludge can be prevented from being diluted, and in addition, the speed of the sludge circulation should not be too fast, preferably the same as the speed of the sludge in the sludge collection tank 11.
Further, the charging device 52 includes a mixing device 521 and a charging pump 522, and an inlet and an outlet of the charging pump 522 are respectively communicated with inlets of the mixing device 521 and the sludge pump 51. The mixing device 521 mixes the surfactants and then passes the mixture through the liquid feeding pump 522 to the inlet position of the sludge pump 51.
Further, the sludge treatment apparatus 5 further comprises a three-way reversing valve 53, wherein two ports of the three-way reversing valve 53 are respectively communicated with the outlet of the sludge pump 51 and the sludge inlet 13, and the other port is connected with a sludge outlet pipe 54. By providing the three-way reversing valve 53, the outlet of the sludge pump 51 can be communicated with the sludge inlet 13 during sludge circulation, and the outlet of the sludge pump 51 can be communicated with the sludge outlet pipe 54 when sludge discharge is required, so that sludge circulation and sludge discharge can be used for both purposes.
By arranging the sludge treatment device 5, on the one hand, chemical agents can be added during the sludge circulation to precipitate the produced colloid, and on the other hand, sludge can be discharged after the sludge circulation. By discharging the sludge from the sludge outlet 12 to the sludge inlet 13, the sludge mixed with the chemical agent can be passed through the porous plate 422 again, thereby dispersing the chemical agent.
The foregoing examples illustrate only a few embodiments of the application and are described in detail herein without thereby limiting the scope of the application. It should be noted that it will be apparent to those skilled in the art that several variations and modifications can be made without departing from the spirit of the application, which are all within the scope of the application.
