Description

Technical Field

[0001] The present invention relates to the field of sewage treatment, and in particular to a device and method for treating water pollution caused by water gushing during construction of a high-speed railway tunnel. Background Art

[0002] Wastewater treatment during construction refers to the process of collecting, treating and purifying wastewater generated at construction sites or other construction sites to reduce the pollution to the environment caused by construction activities. This usually includes removing sediment, chemicals and other suspended matter from wastewater to ensure that the wastewater meets discharge standards or can be reused.

[0003] Tunnel water in high-speed rail construction mainly comes from groundwater. Its water quality is characterized by high pH, ​​petroleum, suspended solids and other pollutants, often showing the characteristics of high turbidity alkaline wastewater, but the pollutants are mainly conventional pollutants. During the construction of high-speed rail, if the tunnel water is not treated, the direct discharge of a large amount of water is very likely to pollute the surrounding ecological environment. Especially when the high-speed rail line passes through the drinking water source protection area, the negative impact of tunnel water on the water quality of surrounding rivers is more serious, and the treatment effect of water is required to be higher. The actual survey results show that although sedimentation, dosing, filter press and other treatment measures are adopted for tunnel water, the indicators of various aspects of the whole water vary greatly at different sampling dates. For example, on different dates of construction of a specific project, the pH values ​​were 10.7 and 10.8, the chemical oxygen demand (the amount of oxidant consumed when treating a water sample with a strong oxidant) was 19 and 8 mg / L, the petroleum was 1.72 and 0.23 mg / L, the suspended solids were 6 and 25 mg / L, and the five-day biochemical oxygen demand (based on the amount of dissolved oxygen consumed by microorganisms to decompose biodegradable organic matter in water under specific conditions) was 6.0 and 2.6 mg / L. All indicators of the gushing water still do not meet the requirements of the water environment quality standards.

[0041] Reference Figures 1 to 9 In one embodiment of the present invention, a water pollution treatment device for water inrush during high-speed railway tunnel construction comprises:

[0042] A plurality of water treatment units 100 are detachably connected in series in the height direction, wherein the water treatment unit 100 comprises a barrel body 110 and a stirring function unit 120, wherein the barrel body 110 comprises a top plate 111 and a peripheral wall plate connected to the periphery of the lower surface of the top plate 111, wherein an interface 112 is arranged on the peripheral wall plate, a conducting port 113 is arranged on the top plate 111, and a concave mounting cap 130 is arranged in the middle of the top plate 111, wherein the stirring function unit 120 comprises a rotating shaft 121, wherein the rotating shaft 121 is provided with a plurality of water treatment units 10 ...

[0045] In the prior art, conventional water treatment processes include coagulation, sedimentation and filtration. In tunnel construction sites, it is difficult to achieve the precise treatment structure and process conditions of sewage treatment plants, and therefore it is also difficult to treat gushing water efficiently and with high quality.

[0046] In the present invention, a plurality of water treatment units 100 are detachably connected in series in the height direction. An appropriate number of water treatment units 100 can be selected for series connection as needed. The connection method between adjacent water treatment units 100 is not limited, and can be a threaded connection or a flange connection, etc. The water treatment unit 100 includes a barrel body 110 and a stirring function unit 120. The stirring function unit 120 is installed on the barrel body 110 to achieve a stirring effect, so that the gushing water is purified in the barrel body 110. The barrel body 110 includes a top plate 111 and a peripheral wall plate connected to the periphery of the lower surface of the top plate 111. The connection method between the top plate 111 and the peripheral wall plate is not limited, and can also be an integrated structure. Specifically, during use, the top plate 111 of the entire barrel body 110 is upside down. An interface 112 is provided on the peripheral wall plate, and the number of interfaces 112 on the peripheral wall plate is not limited to one. Reagent introduction or sample export can be completed through the interface 112; a conducting port 113 is provided on the top plate 111, and the function of the conducting port 113 is to provide a basis for the water gushing in the lower barrel body 110 to flow to the upper barrel body 110. A concave mounting cap 130 is provided in the middle of the top plate 111. The mounting cap 130 can be connected to the top plate 111 or integrally formed. The mounting cap 130 provides a basis for the installation of the stirring function part 120, and specifically the upper and lower mounting caps 130 can complete the definition of the stirring function part 120. The stirring function part 120 includes a rotating shaft 121, and the upper and lower ends of the rotating shaft 121 in the length direction are respectively a magnetic action cap 122 and a magnetic action head 123. When the two barrel bodies 110 are connected, the magnetic action cap 122 forms a rotational fit with the outer wall of the upper mounting cap 130, the magnetic action head 123 forms a rotational fit with the inner wall of the lower mounting cap 130, and the magnetic action cap 122 and the magnetic action head 123 form a magnetic effect. A stirring member 124 is provided on the periphery of the rotating shaft 121. When the stirring function part 120 rotates, the stirring member 124 completes the stirring action. When the two barrel bodies 110 are connected, the mounting caps 130 on the two barrel bodies 110 form an installation and fixation for the stirring function part 120. Specifically, the magnetic action cap 122 on the stirring function part 120 is rotationally matched and arranged on the outer periphery of the upper mounting cap 130, and the magnetic action head 123 on the stirring function part 120 extends into the lower mounting cap 130 and forms a rotational fit with its inner periphery, so that the upper and lower ends of the stirring function part 120 can be respectively limited by a mounting cap 130 to complete the rotation. The inner wall and the outer wall of the mounting cap 130 may be provided with a bearing structure to provide a basis for the installation of the stirring function part 120, but in the preferred embodiment, the bearing structure is not required to provide greater flexibility for the operation of the water pollution treatment device, which will be described in detail in the subsequent embodiments. Except for the stirring function part 120 at the bottom, the others are fixed by the mounting caps 130 on the two barrel bodies 110.

[0047] The bottom plate 200 encloses the barrel body 110 installed at the bottom, and the middle part of the bottom plate 200 is concave to form a fixed cavity 210 that is rotatably matched with the outer wall of the mounting cap 130. The bottom of the lowest stirring function part 120 is fixed through the fixed cavity 210 on the bottom plate 200, and the magnetic function cap 122 of the stirring function part 120 is sleeved on the lowest mounting cap 130, and the magnetic function head 123 of the stirring function part 120 extends into the fixed cavity 210 of the bottom plate 200, so that the stirring function part 120 is restricted and fixed in the vertical direction. The fixed cavity 210 can be formed by integrally forming the bottom plate 200, or an external cap-shaped structure is connected to the bottom plate 200.

[0048] The output end of the driving motor 300 is connected to a magnetic driving part 310 that forms a magnetic effect with the magnetic effect cap 122. The magnetic driving part 310 forms a rotational fit with the inner wall of the mounting cap 130 of the top water treatment unit 100. When the driving motor 300 rotates, the magnetic driving part 310 at its output end rotates. A magnetic effect is formed between the magnetic driving part 310 and the magnetic effect cap 122, and at least one of the magnetic driving part 310 and the magnetic effect cap 122 is a magnetic material. The driving motor 300 can drive the top stirring function part 120 to rotate through the magnetic effect.

[0049] Driving process:

[0050] The driving motor 300 can drive the first stirring function part 120 to rotate through magnetic action. A magnetic action can be formed between the magnetic action cap 122 and the magnetic action head 123 (two adjacent stirring function parts 120), and at least one of the magnetic action cap 122 and the magnetic action head 123 is a magnetic material. The previous stirring function part 120 rotates, and the next stirring function part 120 is driven to rotate through the magnetic action between the magnetic action cap 122 and the magnetic action head 123. Through the magnetic linkage, the rotation speed of each stirring function part 120 automatically forms a differential speed; specifically, the rotation speed of the first stirring function part 120 is the fastest, while the rotation speed of the stirring function part 120 of the next sequence is slightly slower. The rotation speeds of the stirring function parts 120 in different water treatment units 100 are inconsistent. According to the different speed requirements of different stages of gushing water treatment, it is selected to be carried out in different water treatment units 100, for example, coagulation and sedimentation are completed in the water treatment unit 100 at the bottom.

[0051] Water flow process:

[0052] The water treatment units 100 are connected in series in the height direction, and the bottom plate 200 is connected below the lowest water treatment unit 100. The gushing water is pumped into the lowest water treatment unit 100 through the pumping mechanism, and under the action of the pumping pressure, the water treatment unit 100 flows from the conduction port 113 on the top plate 111 to a water treatment unit 100 above, until it flows out of the entire water pollution treatment device. In this process, the gushing water can complete the corresponding treatment (mainly chemical treatment) in different water treatment units 100. It should be noted that it is not limited to perform different water treatment processes in different water treatment units 100. Since the flow of gushing water in the water pollution treatment device is uniform, if a certain treatment process requires more time, the treatment process can be completed in multiple water treatment units 100. A one-way valve that conducts upward can be set on the conduction port 113, so that the gushing water between multiple water treatment units 100 will not flow back and affect the sewage treatment.

[0053] Processing process:

[0054] Before entering the water pollution treatment device, the gushing water can be subjected to rough filtration and natural sedimentation, and then pumped into the water pollution treatment device. The sedimentation process after coagulation is completed in the water treatment unit 100 at the bottom, and the rotation speed of the stirring function part 120 at the bottom is already the slowest, which just meets the use requirements. The water treatment unit 100 at the top can complete the addition of liquid, gas or solid reagents through the interface 112; correspondingly complete the steps of pH value treatment and petroleum treatment.

[0055] In summary, a suitable number of water treatment units 100 can be selected for serial connection as needed, which improves the convenience and flexibility of use and has a simple driving structure; when the two barrel bodies 110 are connected, the magnetic action cap 122 forms a rotational fit with the outer wall of the upper mounting cap 130, and the magnetic action head 123 forms a rotational fit with the inner wall of the lower mounting cap 130; the driving motor 300 drives the magnetic driving part 310 to rotate, and the magnetic driving part 310 is linked with the top stirring function part 120. The upper stirring function part 120 rotates, and the next stirring function part 120 is driven to rotate through the magnetic action between the magnetic action cap 122 and the magnetic action head 123. Through the magnetic linkage, the rotation speed of each stirring function part 120 automatically forms a differential, so that the appropriate processing steps are arranged in the corresponding water treatment unit 100, and finally the gushing water can complete the corresponding processing in different water treatment units 100.

[0056] Reference Figures 6 to 9In one embodiment, the water pollution treatment device also includes a spiral drive head 400 that is detachably connected to the outer periphery of the magnetic action head 123, and the spiral drive head 400 is matched with the fixed cavity 210 in the circumferential direction, and a sewage outlet 211 is provided at the bottom of the fixed cavity 210.

[0057] In this embodiment, the rotation of the lowest stirring function part 120 is used to produce a spiral drive effect, thereby completing the sewage discharge action. Specifically, the spiral drive head 400 is connected to the magnetic action head 123 of the stirring function part 120 (bolts or threaded connection, etc.), and the outer periphery of the spiral drive head 400 is a threaded drive ridge, and the outer free end of the threaded drive ridge is matched with the inner wall of the fixed cavity 210. When the spiral drive head 400 rotates with the magnetic action head 123, the sediment in the fixed cavity 210 can be driven downward by the spiral drive head 400 and finally discharged from the sewage outlet 211. The height and pitch of the threaded drive ridge itself have a direct impact on the working characteristics of the entire spiral drive head 400.

[0058] Reference Figures 6 to 8 In one embodiment, the outer periphery of the upper surface of the base plate 200 is inclined downward in the direction toward the fixing cavity 210 .

[0059] In this embodiment, the bottom plate 200 is shaped so that in the water treatment unit 100 at the bottom, the suspended matter and the generated flocculants in the gushing water can be more efficiently transferred to the position of the fixed cavity 210, which facilitates the operation of the spiral drive head 400. In a typical embodiment, the upper surface of the bottom plate 200 is funnel-shaped.

[0060] Reference Figures 4 to 8 In one embodiment, a permanent magnet 500 is disposed in the thickness direction of the mounting cap 130 , and the permanent magnet 500 is disposed corresponding to the top free end of the magnetic action cap 122 .

[0061] In this embodiment, although the stirring function part 120 extends in the vertical direction, the friction between the magnetic action head 123 of the stirring function part 120 and the mounting cap 130 will hinder the rotation of the stirring function part 120. The addition of relevant bearings complicates the structure of the mounting cap 130 and may also interfere with the effect of the magnetic action head 123 and the magnetic action cap 122. Then, considering that the stirring function part 120 is installed vertically, further referring to the principle of the magnetic levitation air compressor (circumferential suspension), the stirring function part 120 is supported in the vertical direction, so that the friction force on the stirring function part 120 is reduced, and the entire stirring function part 120 rotates more smoothly. The permanent magnet 500 can be annular and installed on the mounting cap 130. Since the permanent magnet 500 is arranged corresponding to the free end of the top of the magnetic action cap 122, the permanent magnet 500 can attract the magnetic action cap 122 in the vertical direction, produce a lifting effect, and suspend the stirring function part 120 (axial suspension).

[0062] Reference Figures 4 to 7 In one embodiment, an electromagnetic component 600 is provided in the thickness direction of the mounting cap 130 , and the electromagnetic component 600 is provided corresponding to the top free end of the magnetic action cap 122 , and the driving circuit of the electromagnetic component 600 is arranged along the top plate 111 and led out of the barrel body 110 .

[0063] In this embodiment, by introducing the electromagnetic component 600, the supporting effect of the stirring function part 120 is adjustable, so the speed at which the indirect stirring function part 120 is driven is adjustable. The specific rotation speed of the stirring function part 120 can be set according to the actual process requirements. When the working power of the electromagnetic component 600 is gradually increased, the friction force received by the stirring function part 120 during operation first decreases and then increases. Specifically, in the first stage, the friction force between the magnetic action head 123 of the stirring function part 120 and the mounting cap 130 below is gradually reduced; in the latter stage, the friction force between the magnetic action cap 122 of the stirring function part 120 and the mounting cap 130 above is gradually increased. During the control process, when the rotation speed of the stirring function part 120 is too slow, the power of the electromagnetic component 600 is controlled to reduce the friction resistance of the stirring function part 120, and the rotation speed of the stirring function part 120 is increased; when the rotation speed of the stirring function part 120 is too fast, the power of the electromagnetic component 600 is controlled to increase the friction resistance of the stirring function part 120, and the rotation speed of the stirring function part 120 is reduced.

[0064] In one embodiment, a rotation speed sensor is disposed on the mounting cap 130 corresponding to the stirring function portion 120 , and a driving circuit of the rotation speed sensor is arranged along the top plate 111 and led out of the barrel body 110 .

[0065] In this embodiment, a speed sensor is added so that the speed of the stirring function part 120 can be monitored in real time. The type of the speed sensor can be a Hall type, etc., which is not specifically limited, subject to the speed information that can be obtained. The mounting cap 130 is generally mounted on the top plate 111, so the speed sensor can be fixed at a specific position on the mounting cap 130, and the driving circuit (power line and data transmission line) of the speed sensor can be laid on the top plate 111, and the waterproof effect needs to be considered specifically.

[0066] In one embodiment, the stirring member 124 is detachably disposed on the rotating shaft 121 .

[0067] In this embodiment, in the stirring function part 120, the fixing method of the stirring element 124 on the rotating shaft 121 is set to be detachable, so the stirring characteristics of the stirring function part 120 can be achieved by adjusting the number of stirring elements 124 (a small number of stirring elements 124 stir at high speed, and a large number of stirring elements 124 stir at low speed). It should be noted that the influence of the adjustment of the number of stirring elements 124 on the stirring intensity is negative feedback. For example, if the number of stirring elements 124 increases, the stirring effect will naturally increase; at the same time, since the linkage between the stirring function part 120 and the previous stirring function part 120 is achieved through magnetic action, the number of stirring elements 124 on the downstream stirring function part 120 increases, the resistance to the rotation of the stirring function part 120 increases, and the rotation speed of the stirring function part 120 decreases, and the stirring effect decreases at this time. Therefore, the method of modifying the working state by adjusting the number of stirring elements 124 can change the stirring effect while keeping the stirring intensity as unchanged as possible.

[0068] In one embodiment, when the stirring function portion 120 rotates, the stirring member 124 generates a downward driving effect.

[0069] In this embodiment, the fluid transfer direction between adjacent water treatment units 100 is from the conduction port 113 on the water treatment unit 100 at the lower position to the water treatment unit 100 at the upper position. In order to reduce the situation where the fluid directly enters the upper water treatment unit 100 without being treated, the driving action of the stirring member 124 is set to be downward, that is, when the stirring function part 120 rotates, the stirring member 124 presses the fluid in the barrel 110 downward, and the fluid in the barrel 110 can be more fully treated in the stirring function part 120 and then enter the upper water treatment unit 100 through the conduction port 113. It should be noted that when the stirring function part 120 rotates, due to the setting of the stirring member 124, the stirring function part 120 has an upward trend, the friction force on the stirring function part 120 is reduced, and the rotation is smoother.

[0070] The present invention also provides a method for treating water pollution caused by water gushing during construction of a high-speed railway tunnel, which is applied to the above-mentioned water pollution treatment device and comprises:

[0073] S3. According to the results of the water quality test, multiple reagent delivery pipelines are connected to the multiple interfaces 112 respectively, wherein the reagent delivery pipelines respectively complete the delivery of different water quality treatment reagents;

[0074] S4, pumping the gushing water into the interface 112 of the water treatment unit 100 at the bottom;

[0075] S5, controlling the driving motor 300 to start working and the reagent delivery pipeline to start working.

[0076] In this embodiment, in step S1, the water treatment unit 100, the bottom plate 200 and the driving motor 300 are installed in sequence, thereby completing the assembly process of the water pollution treatment device.

[0077] In step S2, the water quality of the gushing water is tested, which may include various parameters, such as pH value, chemical oxygen demand, ammonia nitrogen, petroleum, suspended solids and five-day biochemical oxygen demand, etc., which are not specifically limited.

[0078] In step S3, according to the results of the water quality test, the reagent delivery pipelines are connected to multiple interfaces 112 respectively. Through the work of the reagent delivery pipelines, the relevant reagents can enter the water treatment unit 100 through the interface 112. It should be noted that multiple reagents can be introduced into one water treatment unit 100, or the same reagent can be introduced into multiple water treatment units 100. The specific matching result depends on the results of the water quality test, and the above access status is not limited to manual, and automatic access adjustment can also be achieved through the relevant valve structure. The state of the reagent is not limited, and it can be solid, liquid or gas.

[0079] In step S4, the gushing water is pumped into the interface 112 of the lowest water treatment unit 100. At this time, under the action of the pumping pressure, the water treatment unit 100 flows from the conducting port 113 on the top plate 111 to the water treatment unit 100 above, until it flows out of the entire water pollution treatment device. A one-way valve that conducts upward can be set on the conducting port 113, so that the gushing water between the multiple water treatment units 100 will not flow back and affect the sewage treatment.

[0080] In step S5, the driving motor 300 is controlled to start working and the reagent delivery pipeline is controlled to start working. In this process, the gushing water can be processed accordingly (mainly chemically) in different water treatment units 100.

[0081] In one embodiment, a rotation speed sensor is provided on the mounting cap 130 corresponding to the stirring function part 120, an electromagnetic component 600 is provided in the thickness direction of the mounting cap 130, and the electromagnetic component 600 is provided corresponding to the top free end of the magnetic action cap 122, and the driving circuit of the electromagnetic component 600 and the rotation speed sensor is arranged along the top plate 111 and led out of the barrel body 110, and the step S5 includes:

[0082] The operation of the electromagnetic component 600 is controlled according to the signal output by the rotation speed sensor on the water treatment unit 100 .

[0083] In this embodiment, the supporting effect of the stirring function part 120 is adjustable, so the speed at which the stirring function part 120 is driven indirectly is adjustable. The specific rotation speed of the stirring function part 120 can be set according to the actual process requirements. When the working power of the electromagnetic part 600 is gradually increased, the friction force of the stirring function part 120 during operation is first reduced and then increased. Specifically, in the first stage, the friction force between the magnetic action head 123 of the stirring function part 120 and the mounting cap 130 below is gradually reduced; in the second stage, the friction force between the magnetic action cap 122 of the stirring function part 120 and the mounting cap 130 above is gradually increased. During the control process, when the rotation speed of the stirring function part 120 is too slow, the power of the electromagnetic part 600 is controlled to reduce the friction force obstruction of the stirring function part 120, and the rotation speed of the stirring function part 120 is increased; when the rotation speed of the stirring function part 120 is too fast, the power of the electromagnetic part 600 is controlled to increase the friction force obstruction of the stirring function part 120, and the rotation speed of the stirring function part 120 is reduced. Finally, the stirring function unit 120 operates at a preset rotation speed through the operation of the electromagnetic component 600 .

[0084] In summary, the water pollution treatment device and method for water gushing during high-speed railway tunnel construction provided by the present invention can select an appropriate number of water treatment units 100 for serial connection as needed, thereby improving the convenience and flexibility of use and having a simple driving structure; when the two barrel bodies 110 are connected, the magnetic action cap 122 forms a rotational fit with the outer wall of the upper mounting cap 130, and the magnetic action head 123 forms a rotational fit with the inner wall of the lower mounting cap 130; the driving motor 300 drives the magnetic driving part 310 to rotate, and the magnetic driving part 310 forms a linkage with the top stirring function part 120, and the upper stirring function part 120 rotates, and the next stirring function part 120 is driven to rotate through the magnetic action between the magnetic action cap 122 and the magnetic action head 123, and through the magnetic linkage, the rotation speed of each stirring function part 120 automatically forms a differential, thereby arranging the appropriate treatment steps in the corresponding water treatment unit 100, and finally the gushing water can complete the corresponding treatment in different water treatment units 100.
