It uses the microorganisms on the filler to degrade harmful substances in the sewage, thereby purifying the harmful substances in the sewage. It is the most widely used sewage treatment equipment in the existing technology.

[0003] In the prior art, fillers with microorganisms cultured inside are usually placed directly into sewage treatment equipment. With the help of the suspension of the fillers, the microorganisms are evenly dispersed in the sewage to purify the sewage. When the microorganisms decompose harmful substances in the sewage, the fillers will also adsorb impurities in the sewage. As the sewage purification continues, the large amount of impurities attached will cause the filler to reduce the purification effect of the sewage. In order to ensure the effect of sewage treatment, new fillers are usually replaced in large quantities at regular intervals. In this process, not only can the sewage treatment operation be unable to continue, but the operation of scooping out the used fillers in the sewage treatment equipment is also relatively inconvenient, which can easily have a significant impact on the sewage treatment efficiency.

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0020] Embodiment: This embodiment provides an upward flow combined biological moving bed sewage treatment integrated equipment, see Figure 1 - Fig.14Specifically, it includes a base frame 1, and three tank bodies 101 stacked from bottom to top are installed on the top of the base frame 1, and a filling guide mechanism is fixedly installed on the bottom of each tank body 101, and the tank body 101 is fixedly connected to the filling guide mechanism above it, and a tank bottom 102 is fixedly installed on the bottom of the lowest filling guide mechanism, and the tank bottom 102 is fixedly connected with a water inlet pipe 103, and a tank cover 105 is fixedly installed on the top of the uppermost tank body 101, and the top of the tank cover 105 is fixedly connected with a drain pipe 106, each tank body 101 is filled with a plurality of filling members 2, and the filling members 2 include a first hollow ball 201 arranged on the outside, and a second hollow ball 202 is arranged in the first hollow ball 201, and the second hollow ball 202 is filled with a culture bed 203, and the top of the first hollow ball 201 A vertically arranged inner cylinder 204 is fixedly installed in the middle position, an outer cylinder 205 slidably mounted on the outside of the inner cylinder 204 is fixedly installed in the middle position on the top of the second hollow ball 202, a reed 206 elastically supported on the bottom of the second hollow ball 202 is fixedly installed in the first hollow ball 201, a first microhole 207 is opened through the bottom of the outer cylinder 205, a second microhole 208 connected to the interior of the inner cylinder 204 is opened above the cylindrical surface of the inner cylinder 204, a third microhole 209 corresponding to the second microhole 208 is opened on the cylindrical surface of the outer cylinder 205, and the third microhole 209 is arranged above the second microhole 208, a vertically arranged air supply pipe 6 is inserted through the three tank bodies 101, and an aeration pipe 601 fixedly connected to the air supply pipe 6 is installed at the bottom of the top tank body 101.

[0021] When the device is in use, the sewage to be treated is transported to the tank bottom 102 through the water inlet pipe 103. With the continuous inflow of sewage, the sewage gradually rises in the tank bottom 102 and overflows into the three stacked tanks 101 from bottom to top. At the same time, the staff connects the upper end of the air supply pipe 6 to an oxygen supply mechanism. A vertical upward spray hole is provided on the top end wall of the aeration pipe 601. With the help of the connection of the air supply pipe 6, the external oxygen supply mechanism can spray oxygen upward into the top tank 101 through the spray hole provided on the aeration pipe 601, thereby making the oxygen content in the top tank 101 high, forming a suitable living environment for aerobic microorganisms. Since the sewage in the three tanks 101 flows from bottom to top, the tank 101 in the middle position is close to the top tank 101, and a small amount of oxygen in the top tank 101 will diffuse into the tank 101 in the middle position, making the oxygen content in the tank 101 in the middle position low, forming a suitable living environment for aerobic microorganisms. The bottom tank 101 is far away from the top tank 101, and the oxygen filled in the top tank 101 is difficult to diffuse into the bottom tank 101, so that the oxygen content in the bottom tank 101 is further reduced, forming a living environment suitable for anaerobic microorganisms. Microorganisms adapted to the living environment in the corresponding tanks 101 are cultured on the culture beds 203 in the fillers 2 placed in the three tanks 101. When the sewage slowly passes through the three tanks 101 from bottom to top, it will first be decomposed and processed by the anaerobic microorganisms in the filler 2 in the bottom tank 101, and then be decomposed and processed by the anoxic microorganisms in the filler 2 in the middle tank 101, and finally be decomposed and processed by the aerobic microorganisms in the filler 2 in the top tank 101, forming a sewage treatment and purification with triple treatment of anaerobic microorganisms, anoxic microorganisms and aerobic microorganisms. After being treated by the device, the sewage is discharged through the drain pipe 106 at the top.

[0022] Under the elastic support of the reed 206, the outer cylinder 205 is sleeved on the outer side of the inner cylinder 204 and keeps moving upward, which makes the third micropore 209 misplaced above the second micropore 208. In this state, there is no hole above the inner cylinder 204 for discharging the air inside the inner cylinder 204. When the sewage flows from bottom to top in the three tank bodies 101, since the first micropore 207 is opened on the bottom end wall of the outer cylinder 205 below the inner cylinder 204, when the upper part of the inner cylinder 204 cannot be exhausted, the sewage overflowing the filler 2 cannot enter the inner cylinder 204, so that the inner cylinder 204 drives the filler 2 to suspend the sewage in the tank body 101. In the water, when sewage flows through the culture bed 203 among the numerous fillers 2, since the culture bed 203 is set as a porous honeycomb structure, the microorganisms on the culture bed 203 can not only decompose the harmful substances in the sewage, but also adsorb the suspended impurities in the sewage and the impurities produced after decomposition on the culture bed 203. With the continuous treatment of the sewage, the attachments on the culture bed 203 gradually increase, so that the weight of the culture bed 203 gradually increases. Driven by the gradually increasing weight of the culture bed 203, the second hollow ball 202 overcomes the elastic support of the reed 206 and moves downward in the first hollow ball 201, and the second hollow ball 202 drives the third micropore 209 opened on the outer cylinder 205 to move downward relative to the inner cylinder 204. When the third micropore 209 moves downward and aligns with the second micropore 208, the second micropore 208 opened on the inner cylinder 204 is connected with the sewage, so that the air retained in the inner cylinder 204 is discharged through the second micropore 208 and the third micropore 209. In this state, the buoyancy provided by the inner cylinder 204 is greatly reduced, and it is unable to provide sufficient buoyancy for the suspension of the filler 2. Finally, the filler 2 that has absorbed enough impurities falls downward to the bottom of the tank body 101, and is finally guided out by the filler guide mechanism connected to the bottom of the tank body 101. After the filler 2 is exported, the staff can clean it and culture new microorganisms on the culture bed 203. The updated filler 2 can re-enter the corresponding tank body 101 through the filler guiding mechanism to realize the cyclic replacement of the filler 2. Compared with the prior art of regularly replacing the filler 2 in the tank body 101 in batches, the device flexibly replaces the fully used filler 2, which can maximize the utilization of the filler 2, which is beneficial to reducing the cost of sewage treatment. In addition, the replacement of the filler 2 will not cause the suspension of sewage treatment, and continuous purification of sewage without stopping can be realized, which is beneficial to ensuring the efficiency of sewage treatment.

[0023] In the specific implementation process, Figure 8As shown, the water inlet pipe 103 is fixedly connected to the upper side end wall of the tank bottom 102, and the bottom of the tank bottom 102 is fixedly connected with a mud discharge pipe 104. The tank bottom 102 is set as a funnel-shaped structure. When the device is used, sewage is injected into the device from the bottom through the water inlet pipe 103. In the process of the sewage slowly rising, no excessive water flow impact will be formed in the tank body 101, which makes the sewage in the tank body 101 in a relatively calm circulation state. The large particles of impurities in the sewage will settle down to the bottom of the tank bottom 102 due to standing still. Since the water inlet pipe 103 is set on the side end wall of the tank bottom 102 The upper position makes it possible for the sewage injected into the water inlet pipe 103 not to impact the sludge impurities deposited in the tank bottom 102, and the sludge discharge pipe 104 for extracting the sludge impurities is connected to the bottom of the tank bottom 102, so that the entry of sewage and the extraction of sludge will not interfere with each other. When the sludge in the tank bottom 102 accumulates to a certain extent, the staff can export the sludge impurities accumulated at the bottom of the tank bottom 102 through the sludge discharge pipe 104. By setting the tank bottom 102 to a funnel-shaped structure, the deposited sludge can be better gathered, thereby facilitating a more stable sludge extraction operation.

[0024] In the specific implementation process, Figure 5 - Figure 6 , Figure 8 and Fig.10 - Fig.11 As shown, the filler guiding mechanism includes a flange cylinder 3 fixedly connected to the bottom of the tank body 101, and the flange cylinder 3 is fixedly connected to a shell body 301 extending to the outside of the tank body 101, a ring cylinder 302 coaxially arranged therewith is fixedly installed at the lower part of the flange cylinder 3, a first filter plate 303 covering the top of the ring cylinder 302 is fixedly installed at the upper part of the flange cylinder 3, and a C-shaped notch 304 is provided at the edge of the first filter plate 303 away from the shell body 301, a swivel 305 is rotatably sleeved on the outer side of the ring cylinder 302, a rotating wheel 306 is rotatably installed in the shell body 301, and a rubber ring belt 307 is commonly transmission-sleeved on the outer sides of the swivel 305 and the rotating wheel 306, and the outer end of the rubber ring belt 307 A large number of evenly distributed rubber partitions 308 are fixedly installed on the wall, and the rubber ring belt 307 cooperates with the flange cylinder 3 and the shell 301 to form a circulating conveying path. The outer size of the rubber partition 308 is adapted to the inner size of the circulating conveying path. A discharge port 309 connected to the circulating conveying path is opened at the rear of the bottom of the shell 301, and a feed port 310 connected to the circulating conveying path is opened at the front of the top of the shell 301. The wheels 306 in the three filling guide mechanisms are on the same side, and a vertically arranged transmission rod is fixedly connected between the two adjacent wheels 306 above and below. A servo motor 4 is fixedly installed in the base frame 1, and the drive shaft of the servo motor 4 is transmission-connected to the lowest wheel 306.

[0025] When the device is in use, the servo motor 4 installed in the base frame 1 can provide power for the rotation of the rotating wheel 306. Since the shells 301 in the three filling guide mechanisms are all arranged in the same vertical direction, and a vertically arranged transmission rod is connected between the upper and lower adjacent rotating wheels 306, only a single servo motor 4 is needed to provide power for the rotation of all the rotating wheels 306, which is beneficial to reducing the use of servo motors 4 and reducing the manufacturing and use costs of the device to a certain extent.

[0026] When the device is in use, the fully utilized filler 2 sinks to the bottom of the tank body 101 due to the increase in weight and the decrease in buoyancy, and falls onto the first filter plate 303 in the filler guide mechanism connected to the bottom of the tank body 101, and slides through the C-shaped notch 304 into the circulating conveying path formed by the flange cylinder 3, the shell 301 and the rubber ring belt 307. When the servo motor 4 drives the wheel 306 to rotate, it drives the rubber ring belt 307 sleeved on the outer side of the rotating ring 305 and the rotating wheel 306 to continuously rotate in one direction, and the discharge port 309 and the feed port 310 are sequentially It is arranged on the path of the rubber ring belt 307 rotating clockwise. With the continuous rotation of the rubber ring belt 307, the rubber partition 308 evenly fixed on its outer end wall will be driven to move synchronously. Under the manipulation of the rubber partition 308, the filling pieces 2 that fall into the circulating conveying path are driven to move synchronously. When the filling pieces 2 are driven through the discharge port 309, the filling pieces 2 in the circulating conveying path will fall downward through the discharge port 309, thereby realizing the export operation of the fully used filling pieces 2, and the subsequent circulating conveying path is in an empty state.

[0027] The staff can then put the cleaned and updated filler 2 back into the empty circulating conveying path through the feed port 310, and under the continuous movement and toggling of the rubber partition 308, the updated filler 2 is reintroduced into the flange tube 3. The weight of the updated filler 2 is less than its buoyancy, and it can be suspended upward through the C-shaped slot 304 into the tank body 101 to achieve the addition operation of the filler 2. The outer size of the rubber partition 308 is adapted to the inner size of the circulating conveying path. The circulating conveying path is divided into a plurality of relatively independent and circulatably movable small spaces by a large number of evenly distributed rubber partitions 308, which can prevent the sewage in the tank body 101 from accidentally flowing out through the filler guiding mechanism, and is beneficial to ensuring the operating stability of the device. During the operation of the device, with the help of the settling and floating of the filler 2, the filler 2 is replaced through the circulatory movement of these small spaces in coordination with the discharge port 309 and the feed port 310, and the operation is flexible and convenient.

[0028] In the specific implementation process, Figure 3 , Figure 5 and Figure 8As shown, the first hollow ball 201 is set to a spherical structure, the top of the first filter plate 303 is set to an inclined structure, and the lowest position of the top of the first filter plate 303 points to the C-shaped slot 304. When the device is in use, by setting the first hollow ball 201 to a spherical structure and setting the top of the first filter plate 303 to an inclined structure pointing to the C-shaped slot 304, the filler 2 that settles on the top of the first filter plate 303 after being fully utilized can more smoothly roll through the C-shaped slot 304 into the circulating conveying path, which is beneficial to ensure the stability of the filler 2 that is fully used in the device when it is exported.

[0029] In the specific implementation process, Figure 4 and Fig.13 As shown, the culture bed 203 is concentrated in the lower position inside the second hollow ball 202, and the center of gravity of the second hollow ball 202 is concentrated in the lower position inside the first hollow ball 201. When the device is used, by concentrating the center of gravity of the filler member 2 in the lower position inside the first hollow ball 201, combined with the spherical structure of the first hollow ball 201, the filler member 2 as a whole forms a tumbler structure, which is beneficial to ensure that the inner tube 204 of the filler member 2 is always in the upper position inside the first hollow ball 201 when the filler member 2 is in use.

[0030] The first hollow ball 201 and the second hollow ball 202 are both divided into two upper and lower hemispherical structures from the middle position, and a connecting piece is fixed between one side of the upper and lower hemispherical structures of the first hollow ball 201 and the second hollow ball 202, and a snap structure is provided between the other sides of the upper and lower hemispherical structures of the first hollow ball 201 and the second hollow ball 202. When the device is used, by setting the first hollow ball 201 and the second hollow ball 202 as upper and lower hemispherical structures that can be opened and re-fastened, it is convenient for the staff to open the filler 2 to replace the internal culture bed 203, which is beneficial to improving the convenience of assembly and use of the filler 2 in the device.

[0031] In the specific implementation process, Figure 8 , Fig. 9 and Fig.12 As shown, a hopper 5 connected to the feed port 310 is fixedly installed on the top of the shell 301, a discharge pipe 501 connected to the discharge port 309 is fixedly installed on the bottom of the shell 301, a filter box 502 connected to the bottom of the discharge pipe 501 is fixedly installed in the base frame 1, and a collection box 503 is fixedly connected to the right side of the filter box 502, a second filter plate 504 obliquely arranged below the discharge pipe 501 is fixedly installed in the filter box 502, and the lower end of the second filter plate 504 is connected to the collection box 503, a pump 505 is fixedly installed on the base frame 1, and the water outlet of the pump 505 is connected to the water inlet pipe 103, a three-way pipe 506 is fixedly installed on the water inlet of the pump 505, and one end of the three-way pipe 506 is connected to a connecting pipe 507 connected to the bottom of the filter box 502.

[0032] When the device is in use, the filler 2 dropped out through the discharge port 309 will fall down along the discharge pipe 501 into the filter box 502. After entering the filter box 502, the filler 2 will fall onto the second filter plate 504. A small amount of sewage carried by the filler 2 during the falling process will pass through the second filter plate 504 and gather at the bottom of the filter box 502, while the filler 2 will roll down along the inclined surface formed by the second filter plate 504 to the collection box 503 for collection. The staff can clean the filler 2 collected in the collection box 503 and reuse it. After cleaning, it can be updated and reused. The used filler member 2 can be put into the feed port 310 through the hopper 5 and sent back into the corresponding tank body 101 for sewage filtering treatment. During the operation of the device, after the pump 505 connected to the water inlet pipe 103 is powered on and started, the sewage can be pressurized and transported to the tank bottom 102 to ensure the stability of the sewage entering the device. At the same time, with the help of the connection between the three-way pipe 506 and the connecting pipe 507, the sewage gathered at the bottom of the filter box 502 can be pumped back into the tank body 101 for purification treatment under the suction action of the pump 505.

[0033] In the specific implementation process, Figure 7 and Figure 8 As shown, the bottoms of the two lower tank bodies 101 are also equipped with aeration pipes 601 fixedly connected to the air supply pipe 6, and the upper parts of the two lower aeration pipes 601 are fixedly equipped with electromagnetic valves 602 arranged in the air supply pipe 6. When the device is used, since the bottoms of the tank bodies 101 in the middle and the lowermost tank bodies 101 are also equipped with aeration pipes 601 fixedly connected to the air supply pipe 6, oxygen supply operation can be performed in each tank body 101. By installing the electromagnetic valves 602 on the air supply pipe 6 above the aeration pipes 601, the oxygen supply operation can be performed in each tank body 101. When oxygen is introduced into the tank 101 in the middle, the upper and middle tanks 101 are in an oxygen-rich environment, and the lower tank 101 is in an oxygen-deficient environment. When oxygen is introduced into the upper, middle and lower tanks 101, the three tanks 101 are in an oxygen-rich environment. This makes it convenient for the staff to flexibly create different microbial living environments for sewage purification according to the material characteristics of the sewage, which is conducive to improving the flexibility of use of the device.

[0034] Specifically, the working principle and operation method of the present invention are as follows: According to the sewage treatment requirements, fillers 2 with different types of microorganisms are placed in the three tanks 101 respectively, and then the pump 505 is powered on to start, and the sewage to be treated is continuously and stably injected into the tank bottom 102 through the water inlet pipe 103. The sewage flows from bottom to top in the three stacked tanks 101. As the sewage is immersed, the fillers 2 placed in each tank 101 are suspended in the sewage under the buoyancy provided by the inner cylinder 204. The external oxygen supply mechanism is connected to the air supply pipe 6 and the aeration pipe 601 to pass oxygen into the corresponding tank 101, and the air supply pipe 601 is connected to the aeration pipe 601 to adjust the pressure. The living environment of the microorganisms in each tank 101 is improved. When the sewage flows through the numerous evenly distributed fillers 2, the microorganisms cultured on the culture bed 203 will decompose and purify the harmful substances in the sewage. The culture bed 203 will adsorb the impurities in the sewage at the same time. The purified sewage is discharged outward through the top drainage pipe 106. When the culture bed 203 adsorbs too many impurities and is used to the maximum, its weight increases due to the adsorption of impurities, causing the second hollow ball 202 to overcome the elastic support of the reed 206 and drive the outer cylinder 205 relative to the inner cylinder 204. The outer cylinder 205 moves downward, and the third micropore 209 is aligned with the second micropore 208 after the outer cylinder 205 moves downward, and finally holes connected to the sewage appear on both the upper and lower sides of the inner cylinder 204, forcing the air retained in the inner cylinder 204 to be discharged, so that the buoyancy provided by the inner cylinder 204 is weakened, causing the filler 2 to sink to the bottom of the tank body 101, and the sinking filler 2 rolls along the top of the first filter plate 303 through the C-shaped notch 304 into the circulation conveying path, and the servo motor 4 is powered on to drive the runner 306 to rotate, thereby driving the rubber ring belt 307 to drive the outer end wall of the rubber ring belt 307 to move. The numerous fixed rubber partitions 308 move in an orderly manner in the circulating conveying path. With the help of the movement of the rubber partitions 308, the filler pieces 2 that have sunk into the circulating conveying path are discharged through the discharge port 309 and enter the filter box 502 along the discharge pipe 501. The discharged filler pieces 2 can be reused after cleaning and updating. The updated filler pieces 2 can be re-introduced into the circulating conveying path through the hopper 5 and the feed port 310, and float again into the tank body 101 after entering the range of the C-shaped slot 304, thereby completing the flexible replacement of the filler pieces 2 that have been fully used.

[0035] The above are only preferred specific implementation modes of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solutions and inventive concepts of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
