[0034] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0035] A water recycling system for a cement plant, such as Figure 1 , including a septic tank, a grille tank, and a regulating tank 2 connected in sequence through connecting pipes. After the sewage flows through the regulating tank 2, it is pumped into the anoxic tank by a sewage lifting pump, and then flows into the aerobic tank and the MBR membrane tank. The effluent from the MBR membrane tank is sterilized by an ultraviolet sterilizer and then discharged into the reuse water tank. The domestic sewage is collected into the septic tank through a pipe network. The water in the reuse water tank is guided to the production circulating water tank, the greening water tank, and the cleaning center through a diversion pipe. The greening water tank can be used for watering trucks and irrigation of green plants, and the cleaning center is used to clean vehicles entering and leaving the factory, so as to achieve the purpose of recycling water and save water resources.

[0036] The MBR membrane pool is equipped with an immersed flat membrane, which is mainly used for solid-liquid separation. Microbial solids can be effectively retained in the reactor, ensuring the stability of the effluent quality. The sludge in the MBR membrane pool is pumped to the sludge pool by the sludge pump, and the supernatant liquid in the sludge pool is discharged from the overflow port and returned to the equalization tank 2 for reprocessing.

[0037] A fine screen is installed in the screen pool, and a rotary mechanical screen with a bar gap of 3mm is used. The fine screen is mainly used to remove relatively fine particles in the sewage to protect the normal operation of subsequent treatment system equipment, prevent scratches and reduce clogging of the MBR membrane.

[0038] Equalization tank: As domestic sewage discharge is uneven and discontinuous, with high peak flow and low peak flow, the equalization tank can fully balance the water volume and adjust the water quality so that sewage can enter the subsequent treatment unit more evenly, thus improving the impact resistance of the entire system. During peak drainage periods, a large amount of sewage can be stored to serve as an emergency and buffer. At the same time, during periods with relatively low drainage volume, a certain amount of treated water is guaranteed to ensure continuous operation of the system, thereby avoiding adverse effects on the biochemical treatment system. The setting of the equalization tank is conducive to reducing operating costs and the impact of water quality fluctuations.

[0039] Anoxic tanks refer to the process where the dissolved oxygen in sewage is below 0.5 mg / L and a large number of denitrifying bacteria proliferate under anoxic conditions. Denitrifying bacteria reduce nitrates under anoxic conditions and release molecular nitrogen (N2) or nitrous oxide (N2O).

[0040] Aerobic ponds are also called aeration ponds. The dissolved oxygen in the water is usually around 2.5 mg / L. Under oxygenated conditions, aerobic microorganisms multiply in large numbers, thus decomposing organic matter through aerobic microorganisms.

[0041] The MBR membrane pool is an immersed flat-sheet membrane reactor with a unique structure. It is set in the aerobic pool, or a separate membrane pool can be set up. The water after aerobic aeration and biological treatment is pumped out by membrane filtration into the reuse water pool. The MBR membrane pool operates aerobically, with dissolved oxygen ≥2mg / L, effectively removing nitrogen and phosphorus.

[0042] Domestic sewage is collected into the septic tank through the pipe network, flows through the screen tank to remove large particles of solid matter, domestic garbage and impurities, and then flows into the regulating tank by gravity. In the regulating tank, the water quality and water quantity are evenly adjusted, and finally pumped into the anoxic tank by a sewage lift pump. The sewage passes through the A / O system composed of the anoxic tank, aerobic tank and MBR membrane tank to further remove phosphorus and nitrogen, and finally is discharged into the reuse water tank after sterilization by ultraviolet sterilizer. After the above treatment, the domestic sewage of the cement plant is recycled to reduce the waste of water resources.

[0043] like Figure 2 and Figure 3The cleaning center includes a clean water tank 51 connected to the shunt pipe, a sedimentation tank 52 located on one side of the clean water tank 51, and a cleaning passage 53 located on one side of the sedimentation tank 52 and the clean water tank 51 for vehicles to pass through; the clean water tank 51 and the sedimentation tank 52 are located on the same straight line and are both located on one side of the cleaning passage 53. The pump on the shunt pipe transports the clean water in the reuse water tank to the clean water tank 51 for washing the vehicle, and the setting of the sedimentation tank 52 facilitates the sedimentation and reuse of the sewage after washing the vehicle.

[0044] like Figure 2 and Figure 3 A plurality of parallel baffles 54 are provided in the sedimentation tank 52. Both sides of each baffle 54 are fixedly connected to the wall of the sedimentation tank 52. Each baffle 54 is provided with a notch 541 near the wall of the sedimentation tank 52. The notches 541 of two adjacent baffles 54 are staggered, the purpose of which is to slow down the time for water to flow through the baffle 54, thereby facilitating the sedimentation of sewage after washing vehicles. A water inlet 542 is provided on the side of the sedimentation tank 52 away from the clean water tank 51. The water inlet 542 is provided on one side wall of the sedimentation tank 52. The sedimentation tank 52 is provided with a notch 541 connected to the clean water tank. Gap 541 is connected to gap 543, gap 1 541 closest to gap 2 543 is closed by closing piece 1 arranged on sedimentation tank 52, gap 2 543 is also closed by closing piece 1, that is, closing piece 1 controls the opening and closing of gap 1 541 and gap 2 543, and a delivery pipe 544 for delivering clean water to the cleaning channel 53 is provided on the wall of sedimentation tank 52, one end of the delivery pipe 544 is bent into the sedimentation tank 52, and the other end extends to the cleaning channel 53, and a water pump is provided on the delivery pipe 544, and the water pump is located on the wall of sedimentation tank 52.

[0045] like Figure 2 and Figure 3 The cleaning channel 53 includes two inverted U-shaped support frames 55 arranged on the ground and a vertical steel plate 551 connecting the vertical sides of the two support frames 55. A support mesh plate 552 for vehicles to pass through is provided between the two steel plates 551 on the ground. A sewage storage tank 553 is provided below the support mesh plate 552 on the ground. The length direction of the sewage storage tank 553 is perpendicular to the plate surface of the steel plate 551, and one end of the sewage storage tank 553 extends out of the cleaning channel 53 and turns vertically to extend along the side wall of the sedimentation tank 52 to communicate with the water inlet 542 of the sedimentation tank 52. An inclined surface 554 for guiding sewage to the sewage storage tank 553 is provided below the support mesh plate 552 on the ground;

[0046] like Figure 2 and Figure 3The steel plate 551 is provided with a water spray assembly for spraying water on passing vehicles; the water spray assembly includes a water pipe 56 arranged below the opposite sides of the two steel plates 551, the water pipe 56 is horizontally distributed, the upper end faces of the water pipes 56 located on the two steel plates 551 are provided with a water spray pipe 561 extending vertically upward, the lower end of each water spray pipe 561 is connected to the water pipe 56, the water spray pipe 561 is provided with a plurality of nozzles 562 on the side away from the steel plate 551, each water pipe 56 is provided with a water pipe 563 extending downward to the lower end face of the supporting mesh plate 552, and one end of the delivery pipe 544 is connected to the water pipe 563. The height of the water spray pipe 561 varies, the low water spray pipe 561 is convenient for cleaning the tires of the vehicle, and the high water spray pipe 561 is convenient for cleaning the body of the vehicle.

[0047] like Figure 2 and Figure 3 The working principle of the cleaning center: the delivery pipe 544 pumps the clean water in the sedimentation tank 52 to the water pipe 563 through the water pump, and then introduces it into each water pipe 56. The water pipe 56 delivers water to each water spray pipe 561, and washes the vehicle through the nozzle 562. Then the washed sewage flows through the sewage storage tank 553 to the water inlet 542 of the sedimentation tank 52, and the sludge is precipitated in the sedimentation tank 52. After the sewage passes through multiple baffles 54, the impurities in the sewage are precipitated and can be used again;

[0048] like Figure 2 and Figure 3 During the sedimentation process in the sedimentation tank 52, the closure member 1 closes the gap 1 541. When the water level between the sedimentation tank 52 and the baffle 54 closest to the clean water tank 51 is lowered, the water in the clean water tank 51 can flow into the sedimentation tank 52. At this time, the closure member 1 opens the gap 2 543, which is convenient for the water in the clean water tank 51 to flow between the sedimentation tank 52 and the baffle 54 closest to the clean water tank 51, and the gap 1 541 closest to the gap 2 543 is closed by the closure member 1; when the water in the sedimentation tank 52 can be used again after sedimentation, the closure member 1 closes the gap 2 543 and opens the gap 1 541, so that the water in the sedimentation tank 52 flows into the sedimentation tank 52 and the baffle 54 closest to the clean water tank 51, and then is pumped into the cleaning channel 53 by the water pump, thereby achieving the purpose of sewage reuse.

[0049] like Figure 4The first gap 541 closest to the second gap 543 is arranged opposite to the second gap 543. The first closing member includes a sealing plate 57 which is slidably connected to the wall of the sedimentation tank 52 or the surface of the baffle plate 54. The sealing plate 57 seals the first gap 541 and the second gap 543. A driving shaft 571 is rotatably connected to the wall of the sedimentation tank 52. The driving shaft 571 is located between the first gap 541 and the second gap 543. The outer wall of the driving shaft 571 is fixedly connected to levers 572 which extend toward the two sealing plates 57, respectively. The two levers 572 are located on the same straight line. The two levers 572 are located on the same straight line. One end of 72 away from the driving shaft 571 is rotatably connected to the sealing plate 57, and the two levers 572 are telescopic rods. A vertical plate 573 is provided on the pool wall at the upper end of the sedimentation tank 52. A driving shaft 574 parallel to the axis of the driving shaft 571 is rotatably connected to the vertical plate 573. An electric motor for driving the driving shaft 574 to rotate is provided on the vertical plate 573. A driving sprocket 575 is coaxially fixedly connected to the driving shaft 574 and the driving shaft 571. The two driving sprockets 575 are connected by an annular chain 576, that is, the driving sprocket 575 is meshed with the annular chain 576.

[0050] like Figure 4 The motor drives the driving shaft 571 to rotate through two active sprockets 575 and annular chain 576, so that the driving shaft 571 drives the two levers 572 to rotate. At this time, the two levers 572 are respectively located on both sides of the driving shaft 571, so that when one lever 572 rotates upward, the other lever 572 rotates downward. The lever 572 rotating upward drives the sealing plate 57 to move upward, thereby closing the gap 1 541 or the gap 2 543, and the lever 572 rotating downward drives the sealing plate 57 to move downward, thereby opening the gap 1 541 or the gap 2 543. In this process, the lever 572 is a telescopic rod, which can be extended and retracted with the rotation of the driving shaft 571. The structure of the telescopic rod can also be an existing structure. For example, the telescopic rod includes a first rod fixedly connected to the outer wall of the driving shaft 571 and a second rod sleeved on the outer wall of the first rod and sliding on the outer wall of the first rod. The end of the second rod away from the first rod is rotatably connected to the sealing plate 57.

[0052] like Figure 5 and Figure 6 The sewage is discharged into the box body 3 through the pipe 1, and then the sewage in the box body 3 is introduced into the receiving box 6 through the introduction piece. The slide plate 5 is driven by the power piece to move back and forth on the box body 3 and drive the discharge pipe 7 to rotate. At this time, the receiving box 6 moves with the slide plate 5. At this time, the sewage in the receiving box 6 will be discharged into the regulating tank 2 through the discharge pipe 7. The movable receiving box 6 and the rotating discharge pipe 7 improve the uniformity of the sewage when it is discharged into the regulating tank 2, which is convenient for mixing the sewage water quality and is simple and convenient to use.

[0054] like Figure 5 and Figure 7 and Fig. 9 and Fig.11 When the receiving box 6 follows the slide plate 5 to move back and forth along the length direction of the box body 3, the receiving box 6 will pass through each connecting groove 8 one by one. When the receiving box 6 corresponds to one of the connecting grooves 8, the closing plate 9 is pushed horizontally in the direction away from the connecting groove 8 by the pushing member on the receiving box 6, and the tension spring 15 is stretched. At this time, the connecting groove 8 corresponding to the receiving box 6 can be opened. At this time, the sewage in the box body 3 will flow from the opened connecting groove 8 to the receiving box 6. After the receiving box 6 passes through one of the connecting grooves 8, the closing plate 9 can be moved horizontally in the direction close to the connecting groove 8 by the tension spring 15 until the sealing gasket 12 on the closing plate 9 is pressed against the inner wall of the box body 3. At this time, the connecting groove 8 can be closed by the closing plate 9 and the sealing gasket 12. Through the above process, the sewage in the box body 3 can be introduced into the receiving box 6 during the movement of the receiving box 6, which is simple and convenient to use.

[0058] A placement groove 28 is provided at the bottom end of the receiving box 6, and the placement groove 28 is connected to the long strip groove 22. The groove bottom of the placement groove 28 is rotatably connected to two opposite rollers 29, and the two rollers 29 are connected by a belt 30. The long strip groove 22 is located between the two rollers 29 and located below the inner side of the belt 30. The outer side wall of the belt 30 contacts the groove wall of the placement groove 28. The groove bottom of the placement groove 28 is provided with two rectangular mounting frames 31 along the length direction of the long strip groove 22, and the two mounting frames 31 are opposite and evenly positioned. On the inner side of the belt 30, two mounting frames 31 are respectively located on both sides of the long strip groove 22, and the sides of the two mounting frames 31 facing away from each other are in contact with the inner wall of the belt 30. The top of the slide seat 24 is vertically fixedly connected with a transition pipe 32, and the transition pipe 32 is connected with the discharge pipe 7.

[0059] like Figure 6 and Figure 8 and Fig. 9 and Fig.10The bottom box wall in the water guide box 33 is flush with the box bottom in the receiving box 6. When it is necessary to drive the receiving box 6 to move, it is only necessary to turn on the motor 19, and the rotating shaft of the motor 19 drives the driving gear 20 to rotate. At this time, because the driving rack 21 is arranged on the regulating tank 2, and the driving rack 21 is meshed with the driving gear 20, when the rotating shaft of the motor 19 drives the driving gear 20 to rotate, the motor 19 can drive the slide plate 5 to drive the receiving box 6 to move along the length direction of the box body 3 through the cooperation of the driving rack 21 and the driving gear 20. When the receiving box 6 moves, the driving member drives the push plate 5 to move along the length direction of the box body 3 through the driving member. The movable slide 24 slides back and forth horizontally in the rectangular frame 23, and at this time, the discharge pipe 7 will follow the receiving box 6 and move back and forth along the length direction of the rectangular frame 23 following the slide 24. In the process of the discharge pipe 7 following the slide 24 and moving back and forth along the length direction of the rectangular frame 23, the gear ring 26 on the discharge pipe 7 and the driven rack 27 on the rectangular frame 23 cooperate to drive the discharge pipe 7 to rotate.

[0060] When the discharge pipe 7 follows the slide 24 to slide back and forth horizontally in the rectangular frame 23, the transition pipe 32 and the water guide box 33 will follow the slide 24 to move. At this time, because the box mouth of the water guide box 33 is located in the rectangular groove 34, and the groove wall of the rectangular groove 34 is fixedly connected to the water guide box 33, when the transition pipe 32 and the water guide box 33 follow the slide 24 to move, the water guide box 33 will drive the two rollers 29 to rotate through the belt 30, and the belt 30 can block the sewage in the receiving box 6 from the groove opening of the long groove 22, thereby reducing the situation that all the sewage in the receiving box 6 flows out of the receiving box 6 from the long groove 22. Part of the sewage flows into the discharge pipe 7 through the water guide box 33 and the transition pipe 32 in turn. Since the sides of the two mounting frames 31 that are away from each other are in contact with the inner wall of the belt 30, the belt 30 between the two rollers 29 can be reduced through the two mounting frames 31. Since the water in the receiving box 6 bends inward, the water blocking effect of the belt 30 is improved. A disturbance plate (not shown in the figure) for disturbing the sewage in the receiving box 6 is provided on the outside of the belt 30. When the water guide box 33 drives the two rollers 29 to rotate through the belt 30, the sewage in the receiving box 6 can be disturbed by the disturbance plate on the belt 30, which is simple and convenient to use.

The stirring blades 45 are spaced apart along the length direction of the vertical rods 44. The two vertical rods 44 are both arranged on the lower surface of the inclined portion of the discharge pipe 7. The purpose of this arrangement is that the stirring blades 45 on the vertical rods 44 are all located in the water in the regulating tank 2. When the discharge pipe 7 rotates, the discharge pipe 7 will drive the vertical rods 44 to rotate along the rotation axis of the discharge pipe 7. At this time, the sewage in the regulating tank 2 can be stirred by the stirring blades 45 on the vertical rods 44, which is simple and convenient to use.

[0064] like Figure 6 and Fig.11A scraper 46 in the shape of a right triangle is provided below the side of the closing plate 9 away from the sliding column 13, and the inclined surface of the scraper 46 faces upward, and the bottom end of the scraper 46 contacts the bottom end of the box body 3.
