Description

TECHNICAL FIELD

[0001] The present disclosure relates to the technical field of wastewater treatment, in particular to an industrial wastewater phosphorus removal equipment. BACKGROUND

[0002] Industrial wastewater phosphorus removal process is a key technology for reducing the concentration of phosphate in water by physical, chemical or biological methods, mainly including chemical precipitation method, biological phosphorus removal method and adsorption method or membrane separation technology. The purpose is: phosphorus is one of the core elements that cause water body eutrophication. If industrial wastewater is directly discharged without effective phosphorus removal, it will lead to the malignant proliferation of algae in the receiving water body, the depletion of dissolved oxygen, the death of fish and the collapse of the ecosystem, which will seriously damage the balance of water environment and biodiversity. At the same time, environmental protection regulations of various countries have strict restrictions on phosphorus discharge. Enterprises need to achieve compliance discharge through effective phosphorus removal process to avoid high penalties. Efficient phosphorus removal not only ensures the safety of drinking water and the health of the ecosystem, but also is an inevitable requirement for promoting sustainable development of industry and fulfilling environmental responsibility.

[0003] In the prior art, the common schemes in the industrial wastewater phosphorus removal process include chemical precipitation method and biological phosphorus removal method. The chemical precipitation method forms phosphate precipitate by adding calcium salt, iron salt or aluminum salt. However, the flow rate of wastewater injection may change when the conventional chemical reagents are put in, which requires flexible variation of the amount of reagents to be put in, and thus has high requirements for the use of reagent ratio in the early stage, and also easily causes unstable problems of the amount of reagents to be put in. On the other hand, in the process of chemical precipitation method for phosphorus removal, the injection of wastewater is also easy to cause water flow impact to re-suspend the sludge at the bottom, so that part of the sludge at the bottom is also discharged in a small amount when the water is drained.

[0021] The following describes in detail embodiments of the present disclosure, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present disclosure and are not to be construed as limiting the present disclosure. On the contrary, the embodiments of the present disclosure include all variations, modifications, and equivalents that fall within the spirit and scope of the appended claims.

[0022] like Figures 1 to 7 As shown, the embodiment of the present disclosure provides an industrial wastewater phosphorus removal device, comprising: a treatment tank 1, an adaptive delivery component 7, a diffusion component 8 and a closing mechanism 9; The top of the treatment tank 1 is connected to an injection pipe 4, which is used to transport the wastewater to be treated into the interior of the treatment tank 1. The bottom of the treatment tank 1 is integrally formed with a sedimentation bin 6, which has an overall inverted cone structure. The side of the sedimentation bin 6 is connected to a sludge discharge pipe 5, and the side of the treatment tank 1 is connected to a drainage pipe 3; An adaptive delivery assembly 7 is provided at the top of the processing tank 1. The top of the adaptive delivery assembly 7 is connected to a return pipe 13, and the top of the return pipe 13 is connected to the interior of the medicine tank 2. A diffusion assembly 8 is provided in the middle area of ​​the processing tank 1. The bottom of the diffusion assembly 8 is connected to a bottom linkage rod 30. The bottom end of the bottom linkage rod 30 is connected to the sealing mechanism 9. A guide cone plate 28 is welded to the top of the inner wall of the sedimentation bin 6 , and the closing mechanism 9 cooperates with the guide cone plate 28 to separate the interior of the treatment tank 1 from the interior of the sedimentation bin 6 .

[0023] When the dephosphorization device is in use, phosphorus-containing wastewater is injected into the treatment tank 1 at the bottom through the injection pipe 4 at the top, and a chemical dephosphorization agent is injected into the interior of the agent tank 2. As the injection pipe 4 continuously transports the wastewater into the interior of the treatment tank 1, it can first impact the diffusion component 8 in the middle area. Through this impact effect, the diffusion component 8 is controlled to produce a certain lifting movement. With the help of this lifting movement process, the adaptive delivery component 7 at the top and the closing mechanism 9 at the bottom are simultaneously triggered to move. With the help of the adaptive delivery component 7 at the top, the flow rate of the continuously injected chemical dephosphorization agent is flexibly regulated, and the flow rate of the chemical dephosphorization agent is synchronously regulated and matched with the flow rate of the injected wastewater. At the same time, with the help of the lifting movement of the diffusion component 8, the closing mechanism 9 at the bottom is driven to perform synchronous lifting movement, so that when the wastewater injection is stopped and the sludge settled at the bottom is extracted, the internal space of the bottom sedimentation bin 6 can be sealed first to prevent the sludge from being lifted up and floating to the top area again during the sludge extraction process. At the same time, with the help of the only air inlet channel at this time, the discharge process of the internal sludge can be accelerated by drawing in air.

[0024] In this embodiment, the diffusion component 8 includes: The diffuser plate 18, the receiving sleeve 19 and the transmission arm 24 are integrally formed at the bottom of the diffuser plate 18. The top of the diffuser plate 18 is welded with the top linkage rod 16. The side of the diffuser plate 18 is also welded with the transmission arm 24. The end of the transmission arm 24 is inserted with a vertical rod 25. The diffuser plate 18 is of a conical structure as a whole. A guide hole 27 is provided on the top of the diffuser plate 18 . The top linkage rods 16 are symmetrically arranged on both sides of the guide hole 27 . The injected wastewater impacts the surface of the diffuser plate 18 vertically downward.

[0025] The diffusion assembly 8 further comprises: A fixing plate 20, a plug-in sleeve 21, and a fixing frame 23. The fixing frames 23 are integrally formed on both sides of the fixing plate 20. The ends of the fixing frames 23 are used to be welded to the inner wall of the treatment tank 1. The surface of the fixing plate 20 is integrally formed with a plug-in sleeve 21. A spring 22 is provided on the inner side of the plug-in sleeve 21. The top end of the spring 22 is welded and fixed to the bottom surface of the diffuser plate 18, and the bottom end of the spring 22 is welded to the surface of the bottom plate 29. An outwardly protruding limiting ring structure is provided on the outer side of the top of the plug-in sleeve 21, and the plug-in sleeve 21 is embedded in the inner wall of the receiving sleeve 19 through the limiting ring. The fixing frame 23 is symmetrically arranged on both sides of the bottom plate 29.

[0026] A guide hole 27 is also provided in the middle of the bottom plate 29. A sealing plate 26 is installed at the top of the vertical rod 25. The sealing plate 26 has an overall arc-shaped structure and covers one end of the drainage pipe 3 through a lifting movement. The surface of the sealing plate 26 always fits the inner wall of the treatment tank 1. There are two springs 22 , and the two springs 22 are symmetrically arranged on both sides of the guide hole 27 . The diffusion plate 18 is lifted and lowered by the springs 22 and the impact effect of the injected wastewater.

[0027] As the diffusion component 8 moves up and down, the side sealing plate 26 can also be controlled to move up and down synchronously. Therefore, during the injection of wastewater, the sealing plate 26 can always be sealed with the connection area between the drainage pipe 3 and the treatment tank 1 to avoid part of the sludge from entering the drainage pipe 3 with the impact of the water flow during the sewage treatment process, thereby reducing the amount of sludge flowing out.

[0028] Specifically, the injected wastewater enters the bottom area along the conveying channel 10 and eventually directly impacts the conical diffuser plate 18 at the bottom. The diffuser plate 18 evenly diffuses the wastewater in all directions. During this process, the impact effect can also press the entire diffuser plate 18 toward the bottom, causing the transmission arms 24 on the side of the diffuser plate 18 to move downward synchronously. After the transmission arm 24 moves downward, it will drive the vertical pole 25 and the sealing plate 26 at the top of the vertical pole 25 to move downward synchronously. During the wastewater injection process, the above process will be used to block the channel entrance position connecting the drainage pipe 3 and the treatment tank 1 with the help of the sealing plate 26. Therefore, even if the liquid level inside the treatment tank 1 has exceeded the position of the drainage pipe 3, it can avoid the impact of water flow causing a large amount of bottom silt to float and accumulate in the drainage pipe 3, ensuring that after the subsequent sedimentation is completed and when the wastewater injection is stopped to discharge the top layer of liquid, there will not be a large amount of raised silt discharged synchronously.

[0029] In this embodiment, the adaptive delivery component 7 includes: The medicine tank 2, the delivery pump 35, the return pipe 13 and the pumping pipe 14, the medicine tank 2 is screwed to the top of the treatment tank 1, the side of the medicine tank 2 is connected to the delivery pump 35 through a pipe, the other end of the delivery pump 35 is connected to the pumping pipe 14, and the end of the pumping pipe 14 is inserted into the interior of the treatment tank 1.

[0030] The adaptive delivery assembly 7 further comprises: The conveying channel 10, the lifting channel 11, the backflow interlayer 12 and the lifting sleeve 15, the top of the conveying channel 10 is connected with the injection pipeline 4, the outer side of the conveying channel 10 is provided with the lifting channel 11, the outer side of the lifting channel 11 is provided with the backflow interlayer 12, and the inside of the lifting channel 11 is inserted with the lifting sleeve 15; The conveying channel 10, the lifting channel 11, the backflow interlayer 12 and the lifting sleeve 15 are all annular structures, the inner side bottom area of the backflow interlayer 12 is provided with a gap 36, the outer side bottom of the lifting sleeve 15 is provided with a plurality of medicament holes 17, and the inner wall of the lifting sleeve 15 is attached to the surface of the conveying channel 10, and the outer side of the lifting sleeve 15 is attached to the outer surface of the backflow interlayer 12.

[0031] The conveying pump 35 is used for pumping the chemical phosphorus removal agent in the medicament tank 2 into the inside of the pumping pipeline 14, and the end of the pumping pipeline 14 is connected with the top end of the lifting sleeve 15 along the lifting channel 11; The chemical phosphorus removal agent in the lifting channel 11 enters the inside of the backflow interlayer 12 or the treatment tank 1 along the medicament hole 17, the effective components of the chemical phosphorus removal agent include aluminum sulfate, ferric chloride, ferrous sulfate and calcium hydroxide, the end of the backflow pipeline 13 is inserted into the inside of the backflow interlayer 12, the chemical phosphorus removal agent in the inside of the backflow interlayer 12 is re-conveyed to the inside of the medicament tank 2 along the backflow pipeline 13, and the pumping pipeline 14 is symmetrically arranged on both sides of the injection pipeline 4.

[0032] Through the elastic structure of the diffusion assembly 8, the diffusion assembly 8 can be lifted when the sewage is injected, and through the process, the adaptive delivery assembly 7 at the top can be matched, so that the delivery amount of the medicament is increased when the flow rate of the sewage injection is increased, and the pumping pressure of the conveying pump 35 can be automatically matched without adjustment, waste is reduced, and the phosphorus removal process is more stable and balanced.

[0033] Specifically, as the flow rate of the injected wastewater increases, the pressure on the diffusion plate 18 increases, and the spring 22 is compressed to a greater extent, the top lifting sleeve 15 is pulled downward by the top linkage rod 16, so that the medicament holes 17 at the bottom of the lifting sleeve 15 are more exposed to the bottom area of the backflow interlayer 12, that is, the flow rate of the wastewater increases, and more medicament in the lifting sleeve 15 flows into the inside of the treatment tank 1; Obviously, through the above process, after the wastewater injection flow rate changes, the amount of chemical dephosphorization agent injected into the treatment tank 1 can also realize an adaptive regulation process, and the agent hole 17 at the top continues to be aligned with the notch 36. At this time, the agent hole 17 at the top that is not exposed to the interior of the treatment tank 1 can directly inject a part of the agent inside the lifting sleeve 15 into the reflux interlayer 12, and transport the agent to the top reflux pipe 13 through the reflux interlayer 12, and finally reflux to the interior of the agent tank 2 again.

[0034] In this embodiment, the closing mechanism 9 includes: Laminating plate 31, sealing film 34; Among them, the bonding plate 31 is integrally formed at the end of the bottom linkage rod 30, the top end of the bottom linkage rod 30 is welded to the bottom surface of the diffuser plate 18, and the bottom edge of the bonding plate 31 is connected with a sealing film 34. The sealing film 34 has a cylindrical structure as a whole, and the top edge of the bonding plate 31 is used to lean against the bottom area of ​​the guide cone plate 28.

[0035] The closing mechanism 9 further comprises: Base plate 29, air holes 32 and fixing rods 33; An air hole 32 is opened in the middle of the bottom plate 29, and a fixing rod 33 is welded at the bottom edge of the bottom plate 29. The bottom end of the fixing rod 33 is welded to the bottom end of the inner wall of the sedimentation bin 6, and a gap is set between the side of the bottom plate 29 and the inner wall of the sedimentation bin 6.

[0036] The interior of the sedimentation bin 6 is connected to the internal space of the sealing membrane 34 through the air hole 32, the inner side of the sealing membrane 34 is connected to the internal space of the diffusion component 8 through the bottom linkage rod 30, and the interior of the diffusion component 8 is connected to the interior of the conveying channel 10 through the guide hole 27.

[0037] The phosphorus removal equipment is provided with a closing mechanism 9 at the bottom, which moves synchronously through the diffusion component 8. After the water injection is stopped and during the sludge discharge process, the sedimentation bin 6 at the bottom can be directly closed to avoid the reverse flow of the sludge at the bottom during the sludge discharge process. Air can also be drawn in with the help of the injection pipe 4 to accelerate the extraction effect of the sludge at the bottom, making the sludge discharge faster and more thorough.

[0038] Specifically, when the sludge on the bottom layer needs to be extracted, the injection of wastewater is stopped at this time, and the diffuser plate 18 is no longer subjected to the impact force of the wastewater. Therefore, under the action of the spring 22, the diffuser plate 18 can be directly pushed up toward the top. With the upward movement of the diffuser plate 18, the bottom linkage rod 30 can be directly pulled up synchronously, and then the lower fitting plate 31 is pulled up and pressed against the bottom surface area of ​​the guide cone plate 28 until the hole in the middle of the bottom vertebral plate is completely blocked. At this time, the sludge discharge pipe 5 is connected through an external mud pump, and the sludge inside the sedimentation bin 6 is directly extracted through the sludge discharge pipe 5. During the extraction process, the external air passes through the injection pipe 4, the conveying channel 10, the guide hole 27, the bottom linkage rod 30, and the air hole 32 in turn and finally enters the sedimentation bin 6. The sludge inside the sedimentation bin 6 is completely extracted with the help of air pressure. After the wastewater is injected again, the bonding plate 31 can be moved down again, and the wastewater on the top can apply pressure again to cooperate with the diffusion plate 18 to open the bonding plate 31.
