Description

Technical Field

[0001] The present application relates to the technical field of sewage treatment, and in particular to an A3 / O-MBBR membrane process integrated treatment equipment. Background Art

[0002] There are many sewage treatment processes, including relatively mature A0, MBR, SBR and other sewage treatment processes. These processes have been around for a long time and are also widely used sewage treatment processes. However, there will also be some emerging processes that will appear on the market. 3 / 0-MBBR process is one of them. Its core part is MBBR suspended filler with a specific gravity close to that of water. The filler is directly added to the aeration zone as an active carrier of microorganisms. The filler is in a fluidized state by relying on aeration and water flow in the aeration zone. Biofilms of different thicknesses grow inside and outside the filler. The biofilm contains different types of biological flora, of which anaerobic bacteria or facultative anaerobic bacteria are mainly inside and aerobic bacteria are outside. Each carrier is equivalent to a microreactor, which increases the number of microbial flora. On the basis of degrading organic carbon, nitrification and denitrification reactions exist at the same time, thereby improving the overall sewage treatment efficiency. When the sewage flows to the next pool, the cylindrical screen set on the pool wall will ensure that the MBBR filler always works in the aerated pool.

[0003] Because a cylindrical screen is installed on the pool wall to prevent the filler from being lost, the filler will collide with the outside of the cylindrical screen and gather, and it is easy to cause the cylindrical screen to be blocked, affecting the normal passage of sewage flow and further affecting the sewage treatment efficiency. Summary of the invention

[0004] The present application proposes an A3 / O-MBBR membrane process integrated treatment equipment, which has the advantage of reducing the clogging of the drum screen, and is used to solve the problem of drum screen clogging mentioned in the above background technology.

[0005] To achieve the above-mentioned purpose, the present application adopts the following technical scheme: an A3 / O-MBBR membrane process integrated treatment equipment, comprising a packing pool for placing MBBR packing, a sedimentation tank for sewage sedimentation is provided on one side of the packing pool, the packing pool and the sedimentation tank are separated by a fixed plate, water holes are provided at equal intervals laterally on the surface of the fixed plate, and the inner sides of the water holes are connected to cylindrical screens for filtering MBBR packing, a motor assembly is connected above the fixed plate, and the motor assembly drives a horizontally movable vertical support rod, the bottom end of the vertical support rod is connected to a horizontal support rod toward the inner side of the sedimentation tank, the bottom end of the horizontal support rod is connected to a blocking plate corresponding to the number of cylindrical screens, and the sides of two adjacent blocking plates, one closes the end of the cylindrical screen and the other opens the end of the cylindrical screen.

[0006] Furthermore, the connection states of two adjacent cylindrical screens are different.

[0007] Furthermore, when each of the blocking plates opens the cylindrical screen, the blocking plates are all located on the same side of the cylindrical screen, and the motor assembly drives the vertical support rods and the horizontal support rods to drive all the blocking plates to slide horizontally, so that after all the blocking plates move horizontally, the end of the cylindrical screen closed by the side of the blocking plate before moving becomes the end of the cylindrical screen opened, and the end of the cylindrical screen opened by the side of the blocking plate before moving becomes the end of the cylindrical screen closed.

[0008] Furthermore, a telescopic capsule is connected to the center of the blocking plate, a connecting piece is connected to the inner side of the telescopic capsule, and a top end of the connecting piece is connected to the side surface of the fixing plate.

[0009] Furthermore, the telescopic capsule is in an elastic capsule shape, and the telescopic capsule is close to the side opening of the fixed plate. When the telescopic capsule is not subjected to force, the telescopic capsule is entirely located on the inner side of the cylindrical screen.

[0010] Furthermore, a groove for placing the compressed telescopic capsule is provided on the side of the blocking plate close to the fixed plate.

[0011] Furthermore, the connecting member is a connecting belt, the top end of the connecting member is located directly above the cylindrical screen, and the bottom end of the connecting member extends into the inner side of the telescopic capsule and is connected to the center of the end surface of the telescopic capsule.

[0012] The beneficial effect of the present invention is that through the setting of the blocking plate, the blocking plate is used to block the gap between the cylindrical screens, that is, the adjacent cylindrical screens have different connection states and different opening states, and then when the blocking plate is subsequently driven to slide horizontally, the connection states of all the cylindrical screens will be changed again, so that the closed cylindrical screens are opened and the open cylindrical screens are closed, so that the fillers gathered on the outside of the connected cylindrical screens are dispersed due to the closing of the cylindrical screens, and the sludge attached to the surface of the cylindrical screen is pushed by the water flow and separated from the outside of the cylindrical screen, so that the closed cylindrical screen can be connected again for function. Therefore, the circumferential water flow state of the adjacent cylindrical screens is changed by the movement of the blocking plate, so that the blocking of the cylindrical screen can be adjusted.

[0013] Through the setting of the telescopic capsule, at the moment the cylindrical screen is closed, the blocking plate drives the connected telescopic capsule to move, so that the telescopic capsule will extend into the inner side of the cylindrical screen to be closed, and then the extension of the telescopic capsule pushes the water flow inside the cylindrical screen to flow to the outside of the cylindrical screen, so that the cylindrical screen is cleaned by the reverse water flow, thereby reducing the blockage degree of the cylindrical screen and improving the subsequent use efficiency of the cylindrical screen.

[0020] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0021] Embodiment 1

[0022] See also Figure 1 and Figure 2 , an A3 / O-MBBR membrane process integrated treatment equipment, comprising a packing pool 1 for placing MBBR packing, a sedimentation pool 2 for sewage sedimentation is arranged on one side of the packing pool 1, the packing pool 1 and the sedimentation pool 2 are separated by a fixed plate 3, water holes are arranged at equal intervals on the surface of the fixed plate 3, and the inner sides of the water holes are connected to cylindrical screens 4 for filtering MBBR packing, a motor assembly 5 is connected above the fixed plate 3, and the motor assembly 5 drives a horizontally moving vertical support rod 6, the bottom end of the vertical support rod 6 is connected to a horizontal support rod 7 toward the inner side of the sedimentation pool 2, and the horizontal support rod 7 is connected to the inner side of the sedimentation pool 2. The bottom end of the support rod 7 is connected with a blocking plate 8 corresponding to the number of cylindrical screens 4. The motor assembly 5 drives the vertical support rod 6, the transverse support rod 7 and the blocking plate 8 to move at a fast speed. The sides of two adjacent blocking plates 8 close one end of the cylindrical screen 4 and open the other end of the cylindrical screen 4. Through the setting of the blocking plate 8, the motor assembly 5 drives the vertical support rod 6, the transverse support rod 7 and the blocking plate 8 to slide laterally relative to the end surface of the cylindrical screen 4, so that different cylindrical screens 4 are opened or closed, thereby changing the circumferential water flow state of the cylindrical screen 4, reducing the amount of filler gathered around the cylindrical screen 4, and reducing the blockage of the cylindrical screen 4.

[0023] See also Figure 2, the connected states of two adjacent cylindrical screens 4 are different. When each plugging plate 8 opens the cylindrical screen 4, the plugging plates 8 are all located on the same side of the cylindrical screen 4, and the motor assembly 5 drives the vertical support rod 6 and the horizontal support rod 7 to drive all the plugging plates 8 to slide horizontally, so that after all the plugging plates 8 move horizontally, the end of the cylindrical screen 4 closed by the side of the front plugging plate 8 is changed to the end of the cylindrical screen 4 opened, and the end of the cylindrical screen 4 opened by the side of the front plugging plate 8 is changed to the end of the cylindrical screen 4 closed, and the connected states of the adjacent cylindrical screens 4 are different. The arrangement is such that there are connected cylindrical screens 4 on both sides of a closed cylindrical screen 4, so that water flows from the outside of the closed cylindrical screen 4 to the inside of the two connected cylindrical screens 4, and the flow of water drives the sludge blocked on the outside of the cylindrical screen 4 to flow, thereby specifically reducing the amount of sludge attached to the outside of the closed cylindrical screen 4 and reducing the degree of blockage of the cylindrical screen 4. At the same time, due to the conversion of the cylindrical screen 4 from open to closed, the water flow state inside and outside the cylindrical screen 4 is changed, and the evacuation adjustment of the aggregated filler is performed.

[0024] Embodiment 2

[0025] Embodiment 2 is based on Embodiment 1. Please refer to Figure 2 and Figure 3 A telescopic capsule 9 is connected to the center of the blocking plate 8, a connecting piece 10 is connected to the inner side of the telescopic capsule 9, the top of the connecting piece 10 is connected to the side of the fixed plate 3, the outer side of the cylindrical screen 4 in the closed state, the connecting piece 10 is in a vertical state, and the outer side of the connected cylindrical screen 4, the connecting piece 10 is in an oblique state.

[0026] See also Figure 3 The telescopic capsule 9 is in the shape of an elastic capsule, and the telescopic capsule 9 is opened near the side of the fixed plate 3. When the telescopic capsule 9 is not subjected to force, the telescopic capsule 9 is located on the inner side of the cylindrical screen 4 as a whole. The blocking plate 8 is provided with a groove for placing the compressed telescopic capsule 9 on the side of the fixed plate 3. When the cylindrical screen 4 is switched from a connected state to a closed state, the blocking plate 8 drives the telescopic capsule 9 to gradually move to the end of the cylindrical screen 4, so that the connecting piece 10 changes from an oblique state to a vertical state, that is, the distance between the bottom and top ends of the connecting piece 10 at the side ends of the fixed plate 3 becomes smaller, so that the inner side of the telescopic capsule 9 pulls the connecting piece 10 to extend toward the inner side of the closed cylindrical screen 4, thereby pushing the water inside the cylindrical screen 4 to flow to the outside of the cylindrical screen 4. Therefore, the reverse water flows through the inner side of the cylindrical screen 4 to the outer side of the cylindrical screen 4 for cleaning, thereby reducing the blockage degree of the cylindrical screen 4.

[0027] See also Figure 2The connecting piece 10 is a connecting belt, the top of which is located directly above the cylindrical screen 4, and the bottom of which extends into the inner side of the telescopic capsule 9 and is connected to the center of the end face of the telescopic capsule 9. The outer side of the fixed plate 3 and the inner end face of the telescopic capsule 9 are connected by the connecting piece 10, so that when the blocking plate 8 drives the telescopic capsule 9 to move, the distance between the two ends of the connecting piece 10 on the surface where the side face of the fixed plate 3 is located changes, thereby changing the part of the connecting piece 10 on the inner side of the telescopic capsule 9, thereby driving the shape of the telescopic capsule 9 to be compressed or extended, so that the telescopic capsule 9 pushes the water flow inside the cylindrical screen 4 to flow in the opposite direction.

[0028] The method of use (working principle) of the present invention is as follows:

[0029] The sewage flows from the filling tank 1 to the inner side of the sedimentation tank 2 through the cylindrical screen 4. At this time, the connection states of adjacent cylindrical screens 4 connected to the fixed plate 3 are different, that is, the sewage flows to the sedimentation tank 2 through the spaced cylindrical screens 4.

[0030] At this time, the telescopic capsule 9 on the inner side of the closed cylindrical screen 4 will be in an expanded state, so that the bottom end of the connecting piece 10 is pulled to follow the end face of the telescopic capsule 9 and extend into the inner side of the cylindrical screen 4. The top end of the connecting piece 10 is located directly above the cylindrical screen 4 and connected to the side of the fixed plate 3, that is, the connecting piece 10 is in a vertical state at this time, so that the motor assembly 5 drives the vertical support rod 6, the horizontal support rod 7 and the blocking plate 8 to move horizontally and change the connectivity of all the cylindrical screens 4. The movement of the blocking plate 8 will drive the telescopic capsule 9 connected on the inner side to move horizontally. The telescopic capsule 9 drives the bottom end of the connecting piece 10 away from the top end of the connecting piece 10, so that the end face of the telescopic capsule 9 is pulled by the reaction of the connecting piece 10 to move and compress in the direction of the blocking plate 8, and then the telescopic capsule 9 shrinks toward the inside of the blocking plate 8 until the side surface of the blocking plate 8 is completely in close contact with the outside of the fixed plate 3 and closes the corresponding cylindrical screen 4, so that the filler gathered on the outside of the connected cylindrical screen 4 is no longer subject to the thrust of the sewage flowing toward the inside of the cylindrical screen 4. At the same time, the water flow direction outside the cylindrical screen 4 is changed to clean the blocked sludge outside the cylindrical screen 4.

[0031] Again, the motor assembly 5 drives the vertical support rod 6, the horizontal support rod 7 and the blocking plate 8 to move in the opposite direction and change the connectivity of all the cylindrical screens 4. The movement of the blocking plate 8 again will drive the compressed telescopic capsule 9 connected on the inner side to move laterally, so that the telescopic capsule 9 drives the bottom end of the connecting piece 10 close to the top end of the connecting piece 10, so that the telescopic capsule 9 elastically extends into the inner side of the cylindrical screen 4 again, and then the telescopic capsule 9 pushes the water flow inside the cylindrical screen 4 to flow to the outside of the cylindrical screen 4, so that the water flow inside the cylindrical screen 4 flows in the opposite direction, which is convenient for cleaning the blockage of the cylindrical screen 4.
