Description

Technical Field

[0001] The present invention relates to the field of sewage treatment, and in particular to a sewage treatment device with nitrogen and phosphorus removal functions for the treatment of the Yellow River. Background Art

[0002] Water pollution mainly includes domestic wastewater, industrial wastewater and toxic substances. Most of the wastewater generated by people's activities and production in the Yellow River Basin is discharged into the Yellow River after purification treatment. However, due to the increase in population density and production efficiency, the sewage generated by people is also increasing day by day, and nitrogen and phosphorus removal are required in sewage treatment.

[0003] 1. During the use of the nitrogen and phosphorus removal device, a large amount of sludge will adhere to the surface of the hollow fiber membrane after long-term operation, causing blockage of the surface of the hollow fiber membrane. In the process of purifying sewage by the existing nitrogen and phosphorus removal device, it is not convenient to clean the sludge adhering to the surface of the hollow fiber membrane, resulting in the sewage being unable to pass through the hollow fiber membrane efficiently, thereby reducing the nitrogen and phosphorus removal efficiency of the nitrogen and phosphorus removal device for sewage.

[0004] 2. During the nitrogen and phosphorus removal process, the sludge adhering to the surface of the hollow fiber membrane may stick adjacent hollow fiber membranes together, and the sewage cannot enter the hollow fiber membrane through the adhered part of the hollow fiber membranes. In the process of purifying sewage by the existing nitrogen and phosphorus removal device, it is not convenient to separate adjacent hollow fiber membranes in the hollow fiber membrane group and reduce the adhesion between the hollow fiber membranes, thereby further reducing the nitrogen and phosphorus removal efficiency of the nitrogen and phosphorus removal device for sewage.

[0009] In a preferred embodiment of the present invention, the flushing component includes: a plurality of slide rail frames are fixedly connected between the two lifting frames, and the hollow fiber membrane group passes through the slide rail frames; two straight pipes are fixedly connected to each slide rail frame; a plurality of spray heads are fixedly connected to one side of the two straight pipes on each slide rail frame that are close to each other, and the spray heads are in internal communication with the straight pipes; an air guide pipe is fixedly connected between the plurality of straight pipes, and the air guide pipe is in communication with the plurality of straight pipes; a support block is fixedly connected to the bracket; a spiral pipe is fixedly connected between the support block and the air guide pipe, the upper end of the spiral pipe is in communication with the air guide pipe, and the lower end of the spiral pipe is in communication with the air inlet pipe.

[0010] In a preferred embodiment of the present invention, there is also a reciprocating component, the reciprocating component is arranged on the cleaning component, and the reciprocating component is used to assist in cleaning the surface of the hollow fiber membrane group. The reciprocating component includes: support ring frames are fixedly connected to both ends of the two lifting frames; transmission rings are rotatably connected to the four support ring frames, and the transmission rings are slidably connected to the guide screw rods; extrusion rings are fixedly connected to the four transmission rings, and extrusion grooves are provided on the extrusion rings; push rods are fixedly connected to both ends of the two lifting frames, and the push rods are located in the extrusion grooves on the extrusion rings.

[0011] In a preferred embodiment of the present invention, there is also a dispersion component, the dispersion component is arranged on the slide rail frame, the dispersion component is connected to the scraping frame, and the dispersion component is used to disperse the hollow fiber membrane group. The dispersion component includes: an extrusion frame is fixedly connected to one end of each scraping frame, and an inclined groove is provided on the extrusion frame; a sliding frame is slidably connected to each slide rail frame; a push rod is fixedly connected to one end of each sliding frame, and the push rod is located in the inclined groove on the extrusion frame; a plurality of soft rods are fixedly connected to the inner side of each sliding frame.

[0012] In a preferred embodiment of the present invention, it also includes: a plurality of groups of mounting plates are fixedly connected to the bracket, and each group of mounting plates has two; scraping strips are fixedly connected to the lower side of each mounting plate.

[0013] Compared with the prior art, the present invention has the following advantages: 1. Oxygen is supplied to the microorganisms in the sewage tank through the aeration head. The hollow fiber membrane module can intercept the suspended solids and microorganisms in the sewage tank. The microorganisms in the sewage tank carry out denitrification and phosphorus removal treatment on the sewage under aerobic conditions, and then the hollow fiber membrane module filters the sewage. The guiding threaded rod rotates to squeeze the threaded sleeve, lifting frame, slide rail frame, straight pipe, spray head and air duct to move downward, and the guiding threaded rod rotates reversely to squeeze the threaded sleeve, lifting frame, slide rail frame, straight pipe, spray head and air duct to move upward and reset. During the reciprocating up and down movement of the spray head, the high-speed air sprayed from the spray head completely washes off the colloidal sludge attached to the surface of the hollow fiber membrane module, thereby reducing the blockage on the surface of the hollow fiber membrane module. When the scraping frame reciprocates up and down, it will scrape the large pieces of sludge attached to the surface of the hollow fiber membrane module, prompting the large pieces of sludge attached to the surface of the hollow fiber membrane module to fall off, thereby reducing the sludge accumulation on the surface of the hollow fiber membrane module and further reducing the blockage on the surface of the hollow fiber membrane module, so that the sewage can continuously and efficiently pass through the hollow fiber membrane module, and then maintain the efficient denitrification and phosphorus removal of the sewage.

[0014] 2. Whether the extrusion ring rotates forward or reversely, it will squeeze the push rod, transmission bracket and scraping frame to vibrate slightly up and down. Thus, when the scraping frame moves downward or upward, it will vibrate slightly up and down at the same time. The up and down vibration of the scraping frame can rub the large pieces of sludge attached to the surface of the hollow fiber membrane module, making the sludge on the surface of the hollow fiber membrane module fall off more fully, and further reducing the blockage on the surface of the hollow fiber membrane module.

[0015] 3. The slight up and down vibration of the scraping frame drives the extrusion frame to move slightly up and down. The slight up and down movement of the extrusion frame squeezes the push rod, sliding frame and soft rod to move horizontally back and forth. The horizontal reciprocating movement of the soft rod can dial the hollow fiber membrane module, thereby separating the adjacent hollow fiber membranes in the hollow fiber membrane module, reducing the adhesion between the hollow fiber membranes, enabling the hollow fiber membranes to more fully intercept the suspended solids and microorganisms in the sewage tank, and thus improving the efficiency of microorganisms in denitrifying and phosphorus removing the sewage.

[0027] Embodiment 1: A sewage treatment device with nitrogen and phosphorus removal functions for the treatment of the Yellow River, as Figures 1-9 shown, includes: Bracket 1; Mounting frame 2, welded to bracket 1; Four servo motors 3, connected to bracket 1 by bolts; Membrane bioreactor pipe rack 31, connected between bracket 1 and mounting frame 2 by bolts, and a water outlet is provided on membrane bioreactor pipe rack 31; A number of hollow fiber membrane modules 4 are fixedly connected to the membrane bioreactor pipe rack 31, and the number of hollow fiber membrane modules 4 are all communicated with the membrane bioreactor pipe rack 31; An aeration assembly is arranged on the bracket 1 and is used for aerating the sewage; A cleaning assembly is arranged on the mounting frame 2 and is used for cleaning the hollow fiber membrane module 4; A flushing component is arranged on the cleaning component and is used for flushing the sludge on the surface of the hollow fiber membrane module 4.

[0028] The aeration assembly includes: a mounting pipe rack 51 welded to the bracket 1; a number of aeration heads 52 all fixedly connected to the mounting pipe rack 51, and the number of aeration heads 52 are all communicated with the inside of the mounting pipe rack 51; an air inlet pipe 53 welded to one side of the mounting pipe rack 51, the air inlet pipe 53 is communicated with the inside of the mounting pipe rack 51, and an air inlet is provided on the air inlet pipe 53.

[0029] The cleaning assembly includes: two lifting frames 61 both slidably connected to the mounting frame 2; the output shafts of four servo motors 3 are all fixedly connected with guiding threaded rods 62, the four guiding threaded rods 62 are vertically arranged, and each guiding threaded rod 62 is provided with a guiding groove; two lifting frames 61 are both welded with two threaded sleeves 63, and the threaded sleeves 63 are threadedly connected with the guiding threaded rods 62; two transmission brackets 64 are both slidably connected to the two lifting frames 61; a number of scraping frames 65 are fixedly connected between the two transmission brackets 64, each scraping frame 65 is provided with a through groove, and the hollow fiber membrane module 4 passes through the through groove on the scraping frame 65.

[0030] The flushing component includes: a number of slide rail frames 71 fixedly connected between the two lifting frames 61, and the hollow fiber membrane module 4 passes through the slide rail frames 71; two straight pipes 72 are welded to each slide rail frame 71; a number of spray heads 721 are fixedly connected to one side of the two straight pipes 72 on each slide rail frame 71 close to each other, and the spray heads 721 are communicated with the inside of the straight pipes 72; a guide air pipe 73 is welded between the number of straight pipes 72, and the guide air pipe 73 is communicated with the number of straight pipes 72; a support block 74 is fixedly connected to the bracket 1; a spiral pipe 75 is fixedly connected between the support block 74 and the guide air pipe 73, the upper end of the spiral pipe 75 is communicated with the guide air pipe 73, and the lower end of the spiral pipe 75 is communicated with the air inlet pipe 53.

[0031] At first, the worker places the device in the sewage tank, connects the pipe for pumping the purified sewage to the water outlet of the membrane bioreactor pipe rack 31, then connects the pipe for introducing air to the air inlet pipe 53, and then introduces sewage and microorganisms into the sewage tank. The sewage completely submerges the hollow fiber membrane module 4. The worker continuously introduces sewage into the sewage tank, and then continuously pumps the sewage in the sewage tank out through the hollow fiber membrane module 4 and the membrane bioreactor pipe rack 31. Then the worker introduces air into the air inlet pipe 53. A part of the air in the air inlet pipe 53 is introduced into the aeration head 52 through the installation pipe rack 51 and then discharged into the sewage through the aeration head 52 to supply oxygen to the microorganisms in the sewage tank. The hollow fiber membrane module 4 can intercept the suspended solids and microorganisms in the sewage tank and maintain a high sludge concentration in the sewage tank. The microorganisms in the sewage tank carry out denitrification and phosphorus removal treatment on the sewage under aerobic conditions. Then the hollow fiber membrane module filters the sewage. Another part of the air in the air inlet pipe 53 is introduced into the spray head 721 through the spiral pipe 75, the air guide pipe 73 and the straight pipe 72 and then sprayed outwards through the spray head 721. The air sprayed out from the spray head 721 is sprayed on the surface of the hollow fiber membrane module 4 at a relatively high speed, so as to wash off the colloidal sludge attached to the surface of the hollow fiber membrane module 4. Then the worker starts the servo motor 3. The output shaft of the servo motor 3 drives the guiding threaded rod 62 to rotate forward. The guiding threaded rod 62 rotates to squeeze the threaded sleeve 63, the lifting frame 61, the slide rail frame 71, the straight pipe 72, the spray head 721 and the air guide pipe 73 to move downward. The spiral pipe 75 contracts. The transmission support 64 and the scraping frame 65 move downward following the lifting frame 61 under the action of their own gravity. When the threaded sleeve 63, the lifting frame 61, the slide rail frame 71, the straight pipe 72, the spray head 721 and the air guide pipe 73 move to the lowest position, the worker controls the output shaft of the servo motor 3 to rotate reversely. The output shaft of the servo motor 3 drives the guiding threaded rod 62 to rotate reversely. The guiding threaded rod 62 rotates reversely to squeeze the threaded sleeve 63, the lifting frame 61, the slide rail frame 71, the straight pipe 72, the spray head 721 and the air guide pipe 73 to move upward to reset. The spiral pipe 75 stretches again. The lifting frame 61 pushes the transmission support 64 and the scraping frame 65 to move upward to reset. Then the worker controls the output shaft of the servo motor 3 to drive the guiding threaded rod 62 to rotate again. In this way, during the reciprocating movement of the spray head 721 up and down, the high-speed air sprayed out from the spray head 721 completely washes off the colloidal sludge attached to the surface of the hollow fiber membrane module 4, so as to reduce the blockage on the surface of the hollow fiber membrane module 4. When the scraping frame 65 moves up and down reciprocally, it will scrape the large pieces of sludge attached to the surface of the hollow fiber membrane module 4, prompting the large pieces of sludge attached to the surface of the hollow fiber membrane module 4 to fall off, thereby reducing the sludge accumulation on the surface of the hollow fiber membrane module 4 and further reducing the blockage on the surface of the hollow fiber membrane module 4, so that the sewage can continuously and efficiently pass through the hollow fiber membrane module 4, and further maintain the efficient denitrification and phosphorus removal of the sewage.

[0032] Example 2: On the basis of Example 1, as Figure 6, Figure 7 and Figure 9 As shown, it further includes a reciprocating component. The reciprocating component is arranged on the cleaning component and is used to assist in cleaning the surface of the hollow fiber membrane module 4. The reciprocating component includes: Support ring frames 81 are welded to both ends of two lifting frames 61; Transmission rings 82 are rotatably connected to four support ring frames 81, and the transmission rings 82 are slidably connected to the guiding threaded rod 62; Extrusion rings 83 are welded to four transmission rings 82, and extrusion grooves are formed in the extrusion rings 83; Push rods 84 are welded to both ends of two lifting frames 61, and the push rods 84 are located in the extrusion grooves on the extrusion rings 83.

[0033] When the output shaft of the servo motor 3 drives the guiding threaded rod 62 to rotate forward or backward, the guiding threaded rod 62 rotates to drive the transmission ring 82 and the extrusion ring 83 to rotate forward or backward. When the guiding threaded rod 62 rotates forward or backward, it squeezes the threaded sleeve 63, the lifting frame 61, the slide rail frame 71, the straight pipe 72, the nozzle 721 and the air guide pipe 73 to move downward or upward. The lifting frame 61 drives the support ring frame 81, the transmission ring 82, the extrusion ring 83, the transmission bracket 64, the push rod 84 and the scraping frame 65 to move downward or upward. When the extrusion ring 83 rotates forward or backward, it will squeeze the push rod 84, the transmission bracket 64 and the scraping frame 65 to vibrate slightly up and down. Thus, when the scraping frame 65 moves downward or upward, it will vibrate slightly up and down at the same time. The up and down vibration of the scraping frame 65 can rub the large pieces of sludge attached to the surface of the hollow fiber membrane module 4, making the sludge on the surface of the hollow fiber membrane module 4 fall off more fully, and further reducing the blockage on the surface of the hollow fiber membrane module 4.

[0034] Embodiment 3: On the basis of Embodiment 2, as Figures 6-9 shown, it further includes a dispersion component. The dispersion component is arranged on the slide rail frame 71, and the dispersion component is connected to the scraping frame 65. The dispersion component is used to disperse the hollow fiber membrane module 4. The dispersion component includes: Extrusion frames 91 are welded to one end of each scraping frame 65, and inclined grooves are formed in the extrusion frames 91; Slide frames 92 are slidably connected to each slide rail frame 71; Push rods 93 are welded to one end of each slide frame 92, and the push rods 93 are located in the inclined grooves on the extrusion frames 91; A number of soft rods 94 are fixedly connected to the inner side of each slide frame 92.

[0035] When the extrusion ring 83 rotates forward or backward, the extrusion push rod 84, the transmission bracket 64 and the scraping frame 65 will shake slightly up and down. The slight up and down shaking of the scraping frame 65 drives the extrusion frame 91 to move slightly up and down. The small up and down movement of the extrusion frame 91 squeezes the push rod 93, the sliding frame 92 and the soft rod 94 to move back and forth horizontally. The horizontal reciprocating movement of the soft rod 94 can move the hollow fiber membrane group 4, thereby separating the adjacent hollow fiber membranes in the hollow fiber membrane group 4, reducing the adhesion between the hollow fiber membranes, so that the hollow fiber membrane can more fully intercept the suspended matter and microorganisms in the sewage pool, thereby improving the efficiency of microorganisms in denitrifying and removing phosphorus from sewage.

[0036] Embodiment 4: Based on the embodiment 3, Figure 2 , Figure 3 , Figure 6 and Figure 9 As shown, it also includes: a plurality of groups of mounting plates 101 are welded on the bracket 1, and each group of mounting plates 101 has two; a wiper strip 102 is fixedly connected to the lower side of each mounting plate 101, and the wiper strip 102 is horizontally arranged.

[0037] The guide threaded rod 62 rotates forward or reversely to extrude the threaded sleeve 63, the lifting frame 61, the slide rail frame 71, the straight pipe 72, the nozzle 721 and the air guide pipe 73 to move downward or upward. When the nozzle 721 moves to the top, the scraper strip 102 can scrape the surface of the nozzle 721, thereby reducing the sludge on the surface of the nozzle 721 and facilitating the maintenance of air ejection.

[0038] Those skilled in the art should understand that the above embodiments do not limit the present invention in any form, and any technical solutions obtained by equivalent replacement or equivalent transformation shall fall within the protection scope of the present invention.
