Description

Technical Field

[0001] The invention relates to the technical field of sewage treatment equipment, and in particular to an integrated new tunnel sewage treatment system. Background Art

[0002] Tunnel sewage refers to wastewater generated in the tunnel. Generally, this sewage is generated during the tunnel excavation and construction process, because the mountain will be squeezed during the excavation and construction process, which will squeeze out the water in the soil. The mountain itself generally contains hidden water, which will be led out and discharged during the excavation process. Such water will be polluted when it is discharged because the various building materials used in the construction process contain certain substances mixed in the water. This leads to the fact that tunnel sewage cannot be discharged at will and needs to be treated.

[0003] According to the Chinese patent application number "202311270620.2" "A Tunnel Construction Wastewater Treatment System", by setting a cavity, a support plate, a connecting block, and a filter net, one of the filter nets is filtered while the other filter net is flushed in the cavity, which effectively avoids clogging of the filter net, and there is no need to stop filtering when cleaning the residue, thereby improving the filtering efficiency.

[0004] The device flushes the filter screen by setting a water pipe and a cavity to promptly remove residues on the filter screen. At the same time, the first gear, the second gear, and the rotating motor are set to drive the filter screen from a horizontal state to a vertical state or from a vertical state to a horizontal state. In actual application, in order to ensure that the filter screen itself is relatively fixed, the flow direction of sewage is fixed, and the filtering effect will be lost if the direction of the filter screen is changed. At the same time, there is no good sewage discharge structure, resulting in the accumulation of stains cleaned from the filter screen in the cavity. The filter screen still needs to be shut down for cleaning and replacement after long-term use. Therefore, an integrated new tunnel sewage treatment system is proposed. Summary of the invention

An inlet pipe is fixedly connected to the end of the pretreatment tank away from the treatment box and close to the top edge. The inlet pipe has multiple inclined structures with different inclination angles.

[0008] Preferably, the fixing ring is set up as a hollow structure, and a filter disc is connected to both sides of the fixing ring, so that a relatively sealed space can be formed inside the fixing ring, so that the outflow space can collect the filtered residues, which is convenient for cleaning the residues later. The opening and closing of the filling pipe can be controlled by the valve to avoid sewage backflow or affect the discharge of sewage from the filling pipe.

[0009] As a preferred technical solution of the present invention, a filter cloth is detachably connected to a side of the filter disc away from the fixed ring, the filter cloths on the filter discs on both sides of the fixed ring have filter holes of different sizes, through holes are provided through the filter cloth and the filter disc, and a rotating shaft is inserted into the through holes, the filter disc is detachably connected to the outer wall of the rotating shaft, the side wall of the pretreatment tank at one end away from the treatment box is detachably connected to a motor box, and a drive motor is detachably connected to the motor box, and the output end of the drive motor extends into the water diversion trough and is detachably connected to one end of the rotating shaft.

[0010] Preferably, starting the drive motor can drive the rotating shaft to rotate, thereby driving the four pairs of filter discs to rotate.

[0012] Preferably, a collection box is set up to scrape and clean the debris adhering to the filter cloth when the filter disc rotates, thereby realizing the function of cleaning debris without stopping the machine, ensuring the normal operation of the filtration without stopping the machine. At the same time, because the water flowing in the water diversion trough for a long time is only half the height of the filter disc, the cooperation of the filter disc and the collection box can ensure that the filter cloth in contact with the water for filtration is always kept clean, thereby ensuring the effect of real-time filtration treatment.

[0013] As a preferred technical solution of the present invention, a primary treatment tank is opened inside the end of the treatment box close to the pretreatment tank, an isolation plate is fixedly connected inside the treatment box, an anti-overflow plate is set above the isolation plate, and the anti-overflow plate is fixedly connected to the inner wall of the treatment box at both ends, the bottom of one side of the anti-overflow plate is an arc structure, a partition plate is fixedly connected to the middle bottom side wall of the primary treatment tank, the top of the partition plate and the top of the isolation plate are the same inclined structure, the end of the isolation plate close to the anti-overflow plate is an inclined structure and a baffle is evenly fixedly connected on the inclined surface, the baffle is a stepped structure, four cross beams are evenly fixedly connected to the side walls of the partition plate that are far away from each other, each of the cross beams is evenly fixedly connected to the bottom of a vertical column, and the outer wall of each vertical column is evenly fixedly connected to a base cloth.

[0014] Preferably, the sewage can be separated by a partition plate and divided into two chambers for separate treatment. The base cloth can be used as a matrix for bacteria to implant, and harmful substances in the sewage can be decomposed and treated by the bacteria. The two chambers can achieve a two-stage treatment effect, and different bacteria species can be injected into different chambers as needed to improve the efficiency and effect of purification. The tops of the partition plate and the isolation plate are set into an inclined structure, which can increase the retention time of the supernatant and the reaction time with the bacteria to improve the treatment effect. The baffle can intercept the sewage to a certain extent and slow down the flow rate of the sewage outflow, thereby reducing the impact of the outflowing sewage on the water in the sedimentation tank and affecting the effect of static sedimentation.

[0015] As a preferred technical solution of the present invention, an injection column is set above both sides of the partition plate, both ends of the injection column are fixedly connected with a suspension rod, and the suspension rod is detachably connected to the bottom side wall of the sealing plate, and a material receiving pipe is fixedly connected to the middle of the top side wall of the injection column, one end of the material receiving pipe passes through the sealing plate and is connected to a diverter box, and the middle side wall in the diverter box is detachably connected to a partition plate, the bottom of the diverter box and the side walls on both sides of the partition plate are set as a conical structure, the diverter box is detachably connected to the top side wall of the sealing plate, and the middle of the top side wall of the diverter box is detachably connected with a delivery pipe.

[0016] Preferably, the activated sludge can be delivered into the diversion box via a delivery pipe, and the activated sludge can be separated into two parts by a partition plate in the diversion box and finally injected into the two chambers through an injection column.

[0017] As a preferred technical solution of the present invention, a pump case is fixedly connected to the top of the sealing plate and the side wall near the middle, a sludge pump is detachably connected to the inside of the pump case, and a delivery pipe is detachably connected to the output end of the sludge pump, the delivery pipe is a concave structure, the suction pipe is located in the middle of the sedimentation tank, the outer wall of the suction pipe near the bottom is fixedly connected to a cover plate, the cover plate is a trumpet-shaped structure, the side walls on both sides of the bottom end of the suction pipe are through-opened with arc-shaped feed ports, the top of the suction pipe passes through the sealing plate and extends into the pump case and is detachably connected to the suction end of the sludge pump, and the bottom end of the suction pipe is close to the bottom side wall in the sedimentation tank.

[0018] Preferably, starting the sludge pump can extract the activated sludge settled to the bottom of the sedimentation tank through the suction pipe, then send it into the diversion box through the delivery pipe and finally discharge it from the injection column into the primary treatment tank, thereby realizing the recycling of resources and reducing resource consumption.

[0019] As a preferred technical solution of the present invention, the connecting pipe is inserted and connected near a corner of the sealing plate, and four branch pipes are detachably connected to the bottom side wall of the connecting pipe. The side wall of each branch pipe is evenly penetrated with a discharge hole, and a perforated plate is embedded in the discharge hole.

[0020] Preferably, the disinfecting gas can be evenly injected into the treated sewage through the established branch pipes and discharge holes to disinfect the sewage and make it meet the discharge standards.

[0022] Some debris will remain in the fixed ring. Pressurized water will be used to impact the fixed ring through the connecting pipe and the filling pipe to wash away the debris adhering to the inner wall of the filter cloth. The washed debris will be scraped and cleaned by the collection box, while the debris left in the fixed ring will be taken out through the filling pipe and the connecting pipe during the back-drawing, so as to avoid remaining in the fixed ring and affecting the filtering effect.

[0023] The debris scraped into the aggregate box will flow along the discharge vertical pipe into the inclined sewage pipe, and finally be discharged along the sewage pipe, ensuring that no debris remains, thereby ensuring the complete self-cleaning function of the entire filtering equipment and avoiding the accumulation of debris that affects the filtering effect.

[0037] The present invention will be further described below in conjunction with the accompanying drawings.

[0038] Please refer to Figure 1-3 As shown, the present invention is an integrated new type of tunnel sewage treatment system, including a treatment box 1, and a sealing plate 6 located on the top of the treatment box 1, one end of the side wall of the treatment box 1 is fixedly connected to the pretreatment tank 2, the pretreatment tank 2 is provided with a water diversion trough 201, four pairs of filter discs 202 are set in the water diversion trough 201, both sides of the filter disc 202 are provided with a collection box 2011, the side of the collection box 2011 opposite to the filter disc 202 is provided with an inclined structure and the edge is attached to the filter disc 202, the length of the collection box 2011 is the same as the filter disc 202, and the length of the collection box 2011 is the same as the filter disc 202. The radius of the disc 202 is the same, and a filling pipe 204 is evenly interlaced and connected to the side wall of one side of the pretreatment tank 2 and near the bottom edge. One end of the filling pipe 204 is fixedly connected to a connecting pipe 205, and the connecting pipe 205 has a convex three-way structure, and its end away from the filling pipe 204 is connected to the pump. One end of the four filling pipes 204 located in the water diversion trough 201 extends into the bottom of the filter disc 202. A disinfection tank 5 is opened at one end of the treatment box 1 away from the primary treatment tank 3, and a sedimentation tank 4 is opened between the primary treatment tank 3 and the disinfection tank 5;

[0039] A fixing ring 208 is set between each pair of filter discs 202. The fixing ring 208 is a hollow structure. An annular groove is opened on the opposite side of the fixing ring 208 and the filter disc 202. The side wall of the filter disc 202 opposite to the groove is fixedly connected with a swivel, and the filter disc 202 is rotatably connected to the fixing ring 208 through the swivel and the groove. One end of the filling pipe 204 is fixedly connected to the bottom side wall of the fixing ring 208 and communicates with the inside of the fixing ring 208. Each filling pipe 204 and one end close to the connecting pipe 205 are detachably connected with a valve. The pretreatment tank 2 is fixedly connected to the water inlet pipe 203 at one end away from the treatment box 1 and close to the top edge. The water inlet pipe 203 has multiple inclined structures , and the inclination angles are different. The side of the filter disc 202 away from the fixed ring 208 is detachably connected with a filter cloth 2013. The filter holes of the filter cloth 2013 on the filter discs 202 on both sides of the fixed ring 208 are of different sizes. There are through holes in the filter cloth 2013 and the filter disc 202, and a rotating shaft 2014 is inserted into the through holes. The filter disc 202 is detachably connected to the outer wall of the rotating shaft 2014, and the side wall of one end of the pretreatment tank 2 away from the treatment box 1 is detachably connected to the motor box 206, and a driving motor is detachably connected in the motor box 206, and the output end of the driving motor extends into the water diversion groove 201 and is detachably connected to one end of the rotating shaft 2014.

[0040] Specifically, a fixing ring 208 in a hollow annular state is placed in the middle of each pair of filter discs 202, and the two are set up in a rotationally connected relationship. At the same time, because the filling pipe 204 and the fixing ring 208 are fixed and internally communicated, and because the rotating shaft 2014 is inserted in the middle of each filter disc 202, and the filter disc 202 is detachably connected to the rotating shaft 2014, starting the driving motor can drive the rotating shaft 2014 to rotate, thereby driving the four pairs of filter discs 202 to rotate synchronously. As the filter disc 202 rotates, the side with the filter residue adhered can be turned out for easy cleaning, thereby cleaning the residue on the filter cloth 2013, avoiding blockage, and ensuring the normal operation of the filtration. The opening and closing of the filling pipe 204 can be controlled by the valve to avoid the problem of sewage backflow or sewage discharge from the filling pipe 204;

[0041] By setting up the collection box 2011, because its inclined side is in contact with the water inlet pipe 203, as the filter disc 202 rotates, the debris adhering to the water inlet pipe 203 can be scraped off, thereby realizing the function of debris cleaning. At the same time, setting up five collection boxes 2011 can simultaneously clean all the water inlet pipes 203, thereby improving the cleaning efficiency. At the same time, as the filter disc 202 rotates, the effect of cleaning and filtering can be achieved, thereby improving the overall cleaning effect and efficiency.

[0042] Five connecting cross columns 209 are evenly and fixedly connected to the side wall of one side of the water diversion trough 201, and two suspension columns 2010 are fixedly connected to the bottom side wall of each connecting cross column 209. The suspension column 2010 is detachably connected to the top side walls at both ends of the aggregate box 2011 through its end away from the connecting cross column 209. The bottom end of the aggregate box 2011 is a conical structure, and a discharge vertical pipe 2012 is fixedly connected to the bottom side wall of the aggregate box 2011. The bottom end of the discharge vertical pipe 2012 is fixedly connected to a sewage pipe 207, one end of the sewage pipe 207 extends through the side wall of the treatment box 1 and is connected to the collection, and the sewage pipe 207 is an inclined structure.

[0043] Specifically, the connecting horizontal column 209 and the suspension column 2010 can provide sufficient supporting force for the collection box 2011 to ensure that it can be stably set up in the specified position, avoiding problems such as tilting due to the rotation of the filter plate 202, which affects the scraping of debris. The scraped debris enters the collection box 2011 and flows into the sewage pipe 207 along the discharge vertical pipe 2012. Because the sewage pipe 207 is in an inclined state, it can ensure that the debris is smoothly discharged along the inclined sewage pipe 207, avoiding the problem of debris residue or backflow.

[0044] Reference Figure 1 and 4 -5, a primary treatment tank 3 is opened inside the end of the treatment box 1 close to the pretreatment tank 2, an isolation plate 302 is fixedly connected inside the treatment box 1, an anti-overflow plate 303 is set above the isolation plate 302, and the anti-overflow plate 303 is fixedly connected to the inner wall of the treatment box 1 at both ends, and the bottom of one side of the anti-overflow plate 303 is an arc structure, a partition plate 301 is fixedly connected to the middle bottom side wall of the primary treatment tank 3, the top of the partition plate 301 and the top of the isolation plate 302 are the same inclined structure, the end of the isolation plate 302 close to the anti-overflow plate 303 is an inclined structure and a baffle 306 is evenly fixedly connected on the inclined surface, and the baffle 306 is a stepped structure, and the side walls of the partition plate 301 on both sides away from each other are evenly fixedly connected with four cross beams 307, each cross beam 307 is evenly fixedly connected to the bottom of each vertical column 308, and the outer wall of each vertical column 308 is evenly fixedly connected with a base cloth 309.

[0045] Specifically, the sewage can be separated by the partition plate 301 and divided into two chambers for separate treatment. The base cloth 309 can be used as a substrate for bacteria to implant, and the harmful substances in the sewage can be decomposed and treated by the bacteria. The two chambers can achieve a two-stage treatment effect, and different strains of bacteria can be injected into different chambers as needed to improve the efficiency and effect of purification. The tops of the partition plate 301 and the isolation plate 302 are both set into an inclined structure, which can increase the retention time of the supernatant and increase the reaction time with the bacteria to improve the treatment effect. The baffle plate 306 can intercept the sewage to a certain extent and slow down the flow rate of the sewage outflow, thereby reducing the impact of the outflowing sewage on the water in the sedimentation tank 4 and affecting the effect of static sedimentation.

[0046] Reference Figure 1 and 4 -5, an injection column 305 is set above both sides of the partition plate 301, and both ends of the injection column 305 are fixedly connected with a suspension rod, and the suspension rod is detachably connected to the bottom side wall of the sealing plate 6, and a material receiving pipe is fixedly connected to the middle of the top side wall of the injection column 305, and one end of the material receiving pipe passes through the sealing plate 6 and is connected to the diverter box 304, and the middle side wall inside the diverter box 304 is detachably connected to the partition plate 3010, and the side walls on both sides of the bottom of the diverter box 304 and located at the partition plate 3010 are set as a conical structure, the diverter box 304 is detachably connected to the top side wall of the sealing plate 6, and the middle of the top side wall of the diverter box 304 is detachably connected with a conveying pipe 404.

[0047] Specifically, the activated sludge can be delivered to the diversion box 304 via the delivery pipe 404, and the activated sludge can be separated into two parts by the partition plate 3010 in the diversion box 304, and finally injected into two cavities through the injection column 305. The activated sludge falling into the primary treatment tank 3 will naturally settle and fall on the corresponding base cloth 309, which is convenient for the implantation of the bacteria to ensure the purification effect of the bacteria on the sewage in the later stage.

[0048] Reference Figure 1 and 6 As shown, a suction pipe 401 is set up in the sedimentation tank 4, and a pump case 403 is fixedly connected to the top of the sealing plate 6 and near the middle side wall. A sludge pump is detachably connected to the inside of the pump case 403, and the output end of the sludge pump is detachably connected to a delivery pipe 404, and the delivery pipe 404 is a concave structure. The suction pipe 401 is located in the middle of the sedimentation tank 4, and the outer wall of the suction pipe 401 near the bottom is fixedly connected to a cover plate 402, and the cover plate 402 is a trumpet-shaped structure. The side walls on both sides of the bottom end of the suction pipe 401 are penetrated by arc-shaped feed ports 405. The top end of the suction pipe 401 extends through the sealing plate 6 into the pump case 403 and is detachably connected to the suction end of the sludge pump, and the bottom end of the suction pipe 401 is close to the bottom side wall of the sedimentation tank 4.

[0049] Specifically, starting the sludge pump can extract the activated sludge accumulated at the bottom of the sedimentation tank 4 through the suction pipe 401, and finally send it into the diversion box 304 through the delivery pipe 404 to achieve the recycling of the activated sludge. The set cover 402 can limit the activated sludge during suction to prevent the activated sludge from diffusing out due to suction and affecting the sedimentation effect. At the same time, the feed port 405 and the opening of the suction pipe 401 itself can increase the suction coverage area and the suction route of the activated sludge, thereby improving the suction effect and efficiency.

[0050] Reference Figure 1 and 7 As shown, a connecting pipe 501 is provided in the disinfection pool 5, and the connecting pipe 501 is inserted and connected near a corner of the sealing plate 6. Four branch pipes 503 are detachably connected to the bottom side wall of the connecting pipe 501. The side wall of each branch pipe 503 is evenly penetrated with a discharge hole 504, and a perforated plate is embedded in the discharge hole 504. One end of the four branch pipes 503 is fixedly connected to a cross pipe 502, and one end of the connecting pipe 501 extending into the disinfection pool 5 is detachably connected to the top side wall of the cross pipe 502, and the cross pipe 502 is detachably connected to the side walls of the disinfection pool 5 near the bottom at both ends.

[0051] Specifically, the disinfection gas can be uniformly injected into the treated sewage through the established branch pipe 503 and the discharge hole 504, so as to disinfect the sewage and make it meet the discharge standard. At the same time, the perforated plate embedded in the discharge hole 504 can separate the discharged gas into fine bubbles, thereby improving the contact efficiency between the disinfection gas and water, thereby increasing the disinfection effect.

[0052] Specifically, when the present invention is used, sewage is injected into the pretreatment tank 2 through the water inlet pipe 203. Because the water inlet pipe 203 is a multi-stage inclined structure, it can effectively prevent the backflow of sewage. The sewage entering the pretreatment tank 2 will pass through the four pairs of filter discs 202 in sequence, and to ensure the filtering effect, the filter holes of the water inlet pipes 203 on both sides of each pair of filter discs 202 are of different sizes. At the same time, the filter holes of the water inlet pipes 203 on the four pairs of filter discs 202 are smaller as they are closer to the treatment box 1. It is through this gradual change in the size of the filter holes that the debris in the sewage in the pretreatment tank 2 can be effectively filtered to ensure the filtering and purification effect. The driving motor is started to drive the filter disc 202 and the water inlet pipe 203 to rotate via the rotating shaft 2014. As the water inlet pipe 203 rotates, the debris accumulated on the water inlet pipe 203 can be scraped off through the cooperation of the collecting box 2011. After cleaning, the scraped clean water inlet pipe 203 will be transferred to the sewage to continue filtering the sewage, so as to achieve the effect of continuous filtration in circulation and the effect of real-time cleaning of debris. For the debris accumulated in the fixed ring 208, pressurized water is flushed into the fixed ring 208 through the connecting pipe 205 and the filling pipe 204, so as to flush the debris adhering to the inner side of the water inlet pipe 203, and ensure that the flushed debris is collected by the collecting box 2011, and the debris remaining in the fixed ring 208 is extracted from the fixed ring 208 along the filling pipe 204 and the connecting pipe 205 through the reversal of the pump, so as to achieve the effect of comprehensive cleaning of the residual debris without stopping the machine, and improve the filtration efficiency. The sewage after the above filtration is injected into the primary treatment tank 3 through the pump and pipeline between the pretreatment tank 2 and the treatment box 1;

[0053] Through the continuous injection of sewage, it will first react with the bacteria in the first cavity for purification, and the sewage in the pretreatment tank 2 is injected from the bottom of the primary treatment tank 3, and the purified sewage on the upper part will pass over the partition plate 301 and enter the second cavity for secondary purification. Finally, the sewage purified by the bacteria passes between the isolation plate 302 and the anti-overflow plate 303 and enters the sedimentation tank 4 for sedimentation treatment. Similarly, the supernatant in the sedimentation tank 4 is sent to the disinfection tank 5 for disinfection through a pump and a pipeline. Finally, the qualified water is discharged to complete the complete sewage treatment process.

[0054] The above are only preferred embodiments of the present invention. It should be pointed out that, for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention.
