Description

Technical Field

[0001] The present invention belongs to the field of construction wastewater treatment, and specifically is a method for purifying and treating construction wastewater in large-section high-speed railway tunnel groups in ecologically sensitive areas. Background Art

[0002] Ecologically sensitive areas have high environmental protection requirements and harsh construction conditions. In order to prevent tunnel construction wastewater from polluting the environment and damaging the ecological environment, it is necessary to purify and dispose of construction wastewater, and collect and purify the wastewater generated during construction.

[0003] A Chinese patent with publication number CN109289290B discloses an environmentally friendly sewage treatment device for construction, including a base, a treatment tank, a sieve plate and an output pipe, the output pipe is arranged on the lower side of the rear end of the treatment tank; it also includes a support frame and a filter plate, the filter plate is located on the lower side of the sieve plate; it also includes a pressure sensor, a controller, an alarm, a left baffle, a right baffle, a front baffle, and a rear baffle; it also includes a placement box, two groups of first sliders, two groups of second sliders, a first servo motor, a second servo motor and two groups of telescopic motors, a placement slot is provided at the top of the placement box, and the left end of the placement box is connected to the right end of the treatment tank.

[0004] The existing construction wastewater treatment method often involves directly collecting and stacking the wastewater, and then treating and discharging it all. This can easily lead to the sedimentation of foreign matter adhering to the inner wall of the treatment box after the wastewater is left for a long time, resulting in the subsequent cleaning area being too large and difficult to clean.

[0005] To this end, the present invention provides a method for purifying and treating construction wastewater in large-section high-speed railway tunnel groups in ecologically sensitive areas. Summary of the Invention

[0006] In order to make up for the deficiencies of the prior art, at least one technical problem raised in the background technology is solved.

[0007] The technical solution adopted by the present invention to solve the technical problem is: the method for purifying and treating wastewater from construction of large-section high-speed railway tunnels in ecologically sensitive areas of the present invention: the method specifically comprises:

[0008] S1: Place the treatment tank horizontally at the construction site, start the absorption pump to absorb the sewage generated by the construction into the storage tank through the transmission pipe for storage and collection;

[0009] S2: The large impurities and sediment in the sewage are filtered for the first time through the filter frame and the porous material filter pad in the treatment box;

[0010] S3: The filtered sewage is stored and treated separately from the filter frame and continuously stirred. Disinfectant is added to reduce the growth of bacteria during the accumulation process.

[0011] The disinfectant may be a sodium hypochlorite solution;

[0012] This method effectively reduces the problem that during the sewage treatment process, after the sewage has been left for a long time, the precipitated foreign matter adheres to the inner wall of the treatment box, resulting in the subsequent cleaning area being too large and difficult to clean.

[0013] Preferably, a cavity is provided on the inner side of the treatment box, and an absorption pump is provided on one side of the top surface of the treatment box, and the input end of the absorption pump is fixedly connected to a transmission pipe, and a filter frame is fixedly installed on the top of the inner wall of the treatment box, and the filter frame is composed of a double-layer wire mesh, and the top of the filter frame is rotatably connected to a flip plate, and the top of the flip plate is fixedly connected to the absorption pump, and the output end of the absorption pump is located on the inner side of the filter frame. When working, one end of the transmission pipe is placed on the sewage, and the absorption pump is started to suck the sewage into the treatment box. The filter frame composed of wire mesh can filter foreign matter and sediment in the construction sewage, and most of the foreign matter is isolated in the filter frame. When subsequent treatment is required, the filter frame can be cleaned. Through this arrangement, the problem of precipitated foreign matter adhering to the inner wall of the treatment box after the sewage is placed for a long time during the sewage treatment process is effectively reduced, resulting in a large cleaning area and difficulty in cleaning.

[0014] Preferably, a filter pad is provided on the inner side of the filter frame, and the filter pad is made of porous material. A plastic mesh is fixedly inserted inside the filter pad, and the plastic mesh is a flexible material. When working, the filter pad can be a porous sponge material. Through the cooperation of the wire mesh filter frame and the porous filter pad, not only can the silt and other impurities in the sewage be effectively filtered, but the filtered sewage will quickly pass through the filter pad and the filter frame into the treatment box, and will not cause congestion that causes subsequent sewage to be unable to enter. The plastic mesh is set to increase the overall stability of the filter pad. After all filtration is completed, you only need to open the flip plate first, pull out the plastic mesh and filter pad outwards, and a large amount of silt and other impurities can be cleaned at one time.

[0015] Preferably, four groups of storage tubes are rotatably connected to the bottom surface of the cavity of the treatment box, and the four groups of storage tubes are arranged in a ring. One ends of the four groups of storage tubes are fixedly connected to each other, and a large gear is fixedly installed on the bottom end of the connection. A driving component is provided on the outside of the large gear, and a connecting strip is provided on the outside of the storage tube. A float is fixedly installed on the top of the connecting strip. When working, the four groups of storage tubes are driven to rotate by the driving component, and the float will float to the top of the sewage under the action of buoyancy. Then, as the storage tube rotates, it will drive the connecting strip to stir in the sewage, which can reduce the sedimentation of sewage and allow turbid foreign matter in the sewage to remain free in the water. It can reduce the sedimentation of impurities in the sewage to the bottom, which makes it difficult to clean up later. At the same time, the connecting strip and the float will expand outward under the action of centrifugal force, so that the connecting strip is tilted in the sewage, which increases the stirring range and effectively increases the stirring effect.

[0016] Preferably, the connecting strip includes a central belt, the cross-section of the central belt is elliptical, and four groups of extension blocks are fixedly installed on the outside of the central belt, and the four groups of extension blocks are distributed in a ring shape. The cross-section of the extension blocks is elliptical. When working, the shape of the central belt and the four extension blocks are matched so that when the connecting strip stirs the sewage, the contact surface with the sewage is always in an expanded state, and there is sufficient area to stir the sewage, thereby ensuring the function of stirring the sewage. At the same time, due to the hollow setting on the inner side, the overall stirring structure is lighter and can be driven without consuming a lot of power.

[0017] Preferably, the inner side of the storage tube is hollow, the inner side of the center band is hollow, a slider is fixedly installed on the end of the connecting strip away from the float, the slider is slidably connected to the inner side of the storage tube, and an elastic rope is fixedly installed on the bottom end of the float, one end of the elastic rope passes through the middle of the slider and is fixedly connected to the inner wall of the storage tube. When working, the storage tube and the elastic rope are configured so that the float will pull the connecting strip of the same length to extend from the inner side of the storage tube as the water surface is high, thereby reducing the problem of the connecting strip being too long and causing the four groups of connecting strips to be entangled with each other. At the same time, when there is less sewage, the connecting strip extends shorter, and only less power needs to be output to drive the storage tube to rotate, further reducing the energy required for the drive component.

[0018] Preferably, a baffle is fixedly installed on the inner side of the cavity of the treatment box, and the baffle divides the cavity of the treatment box into a first cavity and a second cavity. The filter frame is located in the second cavity, and a water pump is fixedly installed on the outer side of the baffle near the bottom end. The water pump connects the first cavity and the second cavity. A disinfectant is provided on the inner side of the first cavity. The storage tube is located in the first cavity. During operation, the stirring area and the filter frame are separated by the setting of the baffle. After the sewage has been filtered for the first time, the water is pumped into the first cavity again by the water pump to contact the disinfectant. The disinfectant can be sodium hypochlorite, which can reduce the growth of bacteria in the sewage. Through this setting, the water level in the second cavity can be kept at a lower position, reducing the problem that the water level is too high and the sewage is mixed with the sediment in the filter frame again, resulting in the sediment being brought out and the filter pad being soaked for a long time, resulting in reduced filtering effect.

[0019] Preferably, the driving assembly includes a small gear and a driving motor, the small gear is meshed with the large gear, the bottom end of the small gear is connected to a transmission seat, the outer side of the transmission seat is fixedly connected to a pull rope, the inner bottom surface of the second cavity is fixedly installed with an elastic impact plate, the impact plate is arranged in an arc shape, the impact plate is located below the filter frame, the bottom surface of the impact plate is fixedly connected to one end of the pull rope, a fixed rod is fixedly installed inside the processing box, the transmission seat is rotatably connected to the fixed rod, and a torsion spring is connected between the transmission seat and the fixed rod, the driving assembly also wraps the driving motor, the driving motor It is fixedly connected to the bottom end of the large gear. When working, as the sewage continues to fall from the filter frame, it will collide with the top of the impact plate. Combined with the elastic material setting of the impact plate, the impact plate will swing, and in the process of swinging, it will continuously drag the pull rope, thereby pulling the transmission seat to rotate. In addition, the setting of the torsion spring makes the transmission seat continuously rotate forward and reverse. Combined with the small gear to drive the deceleration and lifting movement of the large gear, the storage tube can be effectively rotated forward and reverse. Through this setting, there is no need to consume other energy, and it can also drive the rotation and stirring effect of the sewage in the first cavity. The drive motor is used in the period of time when no water is input for a long time.

[0020] Preferably, the top end of the fixed rod is rotatably connected to a rotating rod, the outer side of the rotating rod is fixedly connected to a ratchet, the inner side of the transmission seat is rotatably connected to a pawl, and the rotating rod is fixedly connected to the pinion. When working, the transmission effect of the ratchet and the pawl is combined so that the pinion will only rotate in one direction, so that the force and speed of the rotation can be gradually increased, rather than rotating forward and backward, thereby effectively increasing the stirring effect and further reducing the precipitation of stains in the sewage, which makes the treatment box difficult to clean later.

[0021] Preferably, the transmission seat is concave in the middle, and the bottom end of the filter frame is funnel-shaped. When working, the structural setting of the transmission seat is coordinated to keep the pull rope in the middle of the transmission seat, reducing the problem of the pull rope falling out. The funnel-shaped filter frame allows the downstream sewage to hit the impact plate in a concentrated manner, maintaining the power transmission effect.

[0022] The beneficial effects of the present invention are as follows:

[0023] 1. The method for purifying and treating sewage from construction of large-section high-speed railway tunnels in ecologically sensitive areas described in the present invention effectively reduces the problem of foreign matter precipitated on the inner wall of the treatment box after the sewage has been left there for a long time, resulting in a large subsequent cleaning area and making it difficult to clean, by providing a filter frame, a filter mat and a storage tube.

[0024] 2. The method for purifying and treating sewage from the construction of a large-section high-speed railway tunnel group in an ecologically sensitive area described in the present invention, in conjunction with the arrangement of a receiving tube and an elastic rope, ensures that the length of the connecting strips will be extended from the inner side of the receiving tube to the same length as the water surface level, thereby reducing the problem of the four groups of connecting strips being entangled with each other due to the connecting strips being too long. At the same time, when there is less sewage, the connecting strips are extended shorter, and only less power needs to be output to drive the receiving tube to rotate, further reducing the energy required for the drive component.

[0033] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0034] Example 1

[0035] like Figure 1 As shown, the method for purifying and treating wastewater from construction of a large-section high-speed railway tunnel group in an ecologically sensitive area according to an embodiment of the present invention is as follows:

[0036] S1: Place the treatment tank 1 horizontally at the construction site, start the absorption pump 3 to absorb the sewage generated by the construction through the transmission pipe 2 into the storage tank 1 for storage and collection;

[0037] S2: The large impurities and sediment in the sewage are filtered for the first time through the filter frame 4 and the porous filter pad 19 in the treatment box 1;

[0038] S3: The filtered sewage is stored separately from the filter frame 4 and continuously stirred, and disinfectant is added to reduce the growth of bacteria during the accumulation process;

[0039] The disinfectant may be a sodium hypochlorite solution;

[0040] This method effectively reduces the problem that during the sewage treatment process, after the sewage has been left for a long time, the precipitated foreign matter adheres to the inner wall of the treatment box 1, resulting in a large subsequent cleaning area and making it difficult to clean.

[0041] like Figures 2 to 3 The top of described flip plate 21 is rotatably connected with the absorption pump 3, and the output end of absorption pump 3 is located at the inner side of filter frame 4. When working, one end of transmission pipe 2 is placed at the sewage, and the absorption pump 3 is started to suck sewage into treatment box 1. With the filter frame 4 composed of wire mesh, foreign matter and sediment in construction sewage can be filtered, and most of foreign matter can be isolated in filter frame 4. When treatment is needed later, focus on cleaning filter frame 4. Through this arrangement, the problem that foreign matter precipitated in sewage after long-term placement adheres to the inner wall of treatment box 1 during treatment is effectively reduced, resulting in that the subsequent cleaning area is too large and difficult to clean is caused.

[0042] like Figures 3 to 5 As shown, a filter pad 19 is provided on the inner side of the filter frame 4, and the filter pad 19 is made of porous material. A plastic mesh 20 is fixedly inserted inside the filter pad 19, and the plastic mesh 20 is made of flexible material. When working, the filter pad 19 can be a porous sponge material. Through the cooperation of the wire mesh filter frame 4 and the porous filter pad 19, not only can the mud and sand and other impurities in the sewage be effectively filtered, but the filtered sewage will quickly pass through the filter pad 19 and the filter frame 4 into the treatment box 1, and will not cause congestion that causes subsequent sewage to be unable to enter. The setting of the plastic mesh 20 is to increase the overall stability of the filter pad 19. After all the filtering is completed, you only need to open the flip plate 21 first, pull out the plastic mesh 20 and the filter pad 19, and a large amount of mud and sand and other impurities can be cleaned at one time.

[0043] like Figures 2 to 3As shown, four groups of storage tubes 12 are rotatably connected to the bottom of the cavity of the treatment box 1. The four groups of storage tubes 12 are arranged in a ring shape. One end of the four groups of storage tubes 12 is fixedly connected to each other, and a large gear 11 is fixedly installed at the bottom end of the connection. A driving component is provided on the outside of the large gear 11, and a connecting bar 13 is provided on the outside of the storage tube 12. A float 14 is fixedly installed on the top of the connecting bar 13. When working, the four groups of storage tubes 12 are driven to rotate by the driving component. The float 14 will float to the top of the sewage under the action of buoyancy. Then, as the storage tube 12 rotates, it will drive the connecting bar 13 to stir in the sewage, which can reduce the sedimentation of sewage and keep the turbid foreign matter in the sewage free in the water. It can reduce the impurities in the sewage from settling to the bottom, which makes it difficult to clean up later. At the same time, the connecting bar 13 and the float 14 will expand outward under the action of centrifugal force, so that the connecting bar 13 is tilted in the sewage, which increases the stirring range and effectively increases the stirring effect.

[0044] like Figure 4 As shown, the connecting strip 13 includes a central belt 16, the cross-section of the central belt 16 is elliptical, and four groups of extension blocks 15 are fixedly installed on the outside of the central belt 16. The four groups of extension blocks 15 are distributed in a ring shape, and the cross-section of the extension blocks 15 is elliptical. When working, the shape of the central belt 16 and the four extension blocks 15 are matched, so that when the connecting strip 13 stirs the sewage, the contact surface with the sewage is always in an expanded state, and there is enough area to stir the sewage, thereby ensuring the function of stirring the sewage. At the same time, due to the hollow setting on the inside, the overall stirring structure is lighter and can be driven without consuming a lot of power.

[0045] like Figures 3 and 4 As shown, the inner side of the storage tube 12 is hollow, the inner side of the center belt 16 is hollow, and the connecting strip 13 is fixedly installed with a slider at one end away from the float 14. The slider is slidably connected to the inner side of the storage tube 12, and the bottom end of the float 14 is fixedly installed with an elastic rope 17. One end of the elastic rope 17 passes through the middle of the slider and is fixedly connected to the inner wall of the storage tube 12. When working, in conjunction with the setting of the storage tube 12 and the elastic rope 17, the float 14 will pull the connecting strip 13 of that length to extend from the inner side of the storage tube 12 as much as the water level is high, thereby reducing the problem of the connecting strip 13 being too long and causing the four groups of connecting strips 13 to be entangled with each other. At the same time, when there is less sewage, the connecting strip 13 extends shorter, and only less power needs to be output to drive the storage tube 12 to rotate, further reducing the energy required for the drive component.

[0046] like Figures 2 to 3As shown, a baffle 6 is fixedly installed on the inner side of the cavity of the treatment box 1, and the baffle 6 divides the cavity of the treatment box 1 into a first cavity and a second cavity. The filter frame 4 is located in the second cavity, and a water pump 8 is fixedly installed on the outer side of the baffle 6 near the bottom end. The water pump 8 connects the first cavity and the second cavity. A disinfectant is provided on the inner side of the first cavity. The receiving tube 12 is located in the first cavity. When working, the stirring area and the filter frame 4 are separated by the setting of the baffle 6. After the sewage is filtered for the first time, the water is pumped into the first cavity again by the water pump 8 to contact with the disinfectant. The disinfectant can be sodium hypochlorite, which can reduce the growth of bacteria in the sewage. Through this setting, the water level in the second cavity can be kept at a lower position, reducing the problem that the water level is too high and the sewage is mixed with the sediment in the filter frame 4 again, resulting in the sediment being brought out and the filter pad 19 being soaked for a long time, resulting in reduced filtering effect.

[0047] like Figures 3 to 6 As shown, the driving assembly includes a small gear 22 and a driving motor, the small gear 22 is meshed with the large gear 11, the bottom end of the small gear 22 is transmission-connected with a transmission seat 10, the outer side of the transmission seat 10 is fixedly connected with a pull rope 9, the inner bottom surface of the second cavity is fixedly installed with an elastic impact plate 5, the impact plate 5 is arranged in an arc shape, the impact plate 5 is located below the filter frame 4, the bottom surface of the impact plate 5 is fixedly connected to one end 9 of the pull rope, the interior of the processing box 1 is fixedly installed with a fixing rod 27, the transmission seat 10 is rotatably connected to the fixing rod 27, and a torsion spring is connected between the transmission seat 10 and the fixing rod 27, and the driving assembly also wraps the driving motor, The driving motor is fixedly connected to the bottom end of the large gear 11. During operation, as the sewage continues to fall from the filter frame 4, it will collide with the top of the impact plate 5. The elastic material setting of the impact plate 5 causes the impact plate 5 to swing. During the swinging process, the pulling rope 9 will be continuously dragged, thereby pulling the transmission seat 10 to rotate. In addition, the setting of the torsion spring causes the transmission seat 10 to continuously rotate forward and reverse. The small gear 22 drives the deceleration and lifting motion of the large gear 11, which can effectively make the storage tube 12 rotate forward and reverse. Through this setting, there is no need to consume other energy, and the rotation and stirring effect of the sewage in the first cavity can also be driven. The driving motor is used in time periods when no water is input for a long time.

[0048] like Figure 6As shown, the top end of the fixed rod 27 is rotatably connected to the rotating rod 24, the outer side of the rotating rod 24 is fixedly connected to the ratchet 25, the inner side of the transmission seat 10 is rotatably connected to the pawl 26, and the rotating rod 24 is fixedly connected to the pinion 22. When working, the transmission effect of the ratchet 25 and the pawl 26 is combined so that the pinion 22 can only rotate in one direction, so that the force and speed of the rotation can be gradually increased, rather than rotating forward and backward, thereby effectively increasing the stirring effect and further reducing the precipitation of stains in the sewage, which makes the treatment box 1 difficult to clean later.

[0049] Example 2

[0050] like Figure 3 and Figure 6 As shown, compared with Example 1, another implementation of the present invention is: the transmission seat 10 is set in a concave shape in the middle, and the bottom end of the filter frame 4 is set in a funnel shape. When working, the structural setting of the transmission seat 10 is coordinated to allow the pull rope 9 to always be in the middle of the transmission seat 10, reducing the problem of the pull rope 9 falling out, and the funnel-shaped filter frame 4 can allow the downstream sewage to concentrate on the impact plate 5, maintaining the power transmission effect.

[0051] During operation, one end of the transmission pipe 3 is placed at the sewage, and the absorption pump 3 is started to suck the sewage into the treatment box 1. The filter frame 4 composed of wire mesh can filter the foreign matter and sediment in the construction sewage, so that most of the foreign matter is isolated in the filter frame 4. When it needs to be treated later, just focus on cleaning the filter frame 4. Through this setting, it effectively reduces the problem that in the sewage treatment process, after the sewage is placed for a long time, the precipitated foreign matter adheres to the inner wall of the treatment box 1, resulting in the subsequent cleaning area being too large and difficult to clean; during operation, the filter pad 19 can be made of porous sponge material. Through the cooperation of the wire mesh filter frame 4 and the porous filter pad 19, not only can the sediment and other impurities in the sewage be effectively filtered, but the filtered sewage will quickly pass through the filter pad 1 9 and the filter frame 4 enter the treatment box 1 without causing congestion and the problem that subsequent sewage cannot enter. The setting of the shaping net 20 is to increase the overall stability of the filter pad 19. After all the filtration is completed, it is only necessary to open the flip plate 21 first and pull out the shaping net 20 and the filter pad 19, so that a large amount of mud and sand and other impurities can be cleaned at one time; when working, the four groups of storage tubes 12 are driven to rotate by the driving component, and the float 14 will float to the top of the sewage under the action of buoyancy. Then, as the storage tube 12 rotates, it will drive the connecting bar 13 to stir in the sewage, which can reduce the sedimentation of sewage and keep the turbid foreign matter in the sewage free in the water, which can reduce the sedimentation of impurities in the sewage to the bottom, causing the problem of subsequent difficulty in cleaning. The strips 13 and the float 14 will expand outwards under the action of centrifugal force, so that the connecting strip 13 is in an inclined state in the sewage, thereby increasing the stirring range and effectively increasing the stirring effect; when working, the shape of the central belt 16 and the four extension blocks 15 is set, so that when the connecting strip 13 stirs the sewage, the contact surface with the sewage is always in an expanded state, and there is enough area to stir the sewage, thereby ensuring the function of stirring the sewage. At the same time, due to the hollow setting on the inside, the weight of the overall stirring structure is light and it can be driven without consuming a lot of power; when working, with the setting of the receiving tube 12 and the elastic rope 17, the length of the connecting strip 13 will be pulled out from the inside of the receiving tube 12 by the length of the float 14 as the water surface is high, thereby reducing the length of the connecting strip 13 that is too high. The problem that the four groups of connecting strips 13 are entangled with each other is caused by the length of the connecting strips 13, and at the same time, when there is less sewage, the connecting strips 13 are extended shorter, and only less power needs to be output to drive the storage tube 12 to rotate, further reducing the energy required for the drive component; when working, the setting of the baffle 6 is used to separate the stirring area and the filter frame 4. After the sewage is filtered for the first time, the water is pumped into the first cavity by the water pump 8 to contact the disinfectant. The disinfectant can be sodium hypochlorite, which can reduce the growth of bacteria in the sewage. Through this setting, the water level in the second cavity can be kept at a low position, reducing the problem that when the water level is too high, the sewage is mixed with the sediment in the filter frame 4 again, resulting in the sediment being brought out and the filter pad 19 being soaked for a long time, resulting in reduced filtration effect.During operation, as the sewage continuously falls from the filter frame 4, it collides with the top of the impact plate 5. The elastic material of the impact plate 5 causes the impact plate 5 to swing. During the swinging process, the pulling rope 9 is continuously dragged, thereby pulling the transmission seat 10 to rotate. In addition, the torsion spring configuration causes the transmission seat 10 to continuously rotate forward and reverse. The small gear 22 drives the large gear 11 to reduce speed and lift, which can effectively cause the storage tube 12 to rotate forward and reverse. Through this configuration, without consuming other energy, it can also drive the rotation and stirring effect of the sewage in the first cavity, and the drive motor can be used for long periods of time when no water is input. During operation, the transmission effect of the ratchet 25 and the pawl 26 causes the small gear 22 to rotate only in one direction, thereby gradually increasing the rotation force and speed, rather than rotating forward and reverse, thereby effectively increasing the stirring effect and further reducing the problem of stains in the sewage settling, which makes the treatment box 1 difficult to clean later.
