Detailed Implementation
[0020] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.
[0021] To address the technical problem of suspended carriers accumulating and clogging aerators in existing technologies, this invention provides a mobile integrated wastewater treatment device. The device uses a purging assembly to rapidly agitate the suspended carriers at the bottom of the aerobic zone, making it less prone to aggregation and thus preventing aerator blockage and improving wastewater treatment efficiency in the aerobic zone.
[0022] Please see Figure 1 , Figure 1 This is a schematic diagram of the structure of a mobile integrated sewage treatment device according to an embodiment of the present invention.
[0023] This invention provides a mobile integrated wastewater treatment device, comprising a shell 1, a first aeration component 2, a purging component 3, and a blower component 4. The shell 1 is movably disposed and contains an anaerobic zone 11, an anoxic zone 12, an aerobic zone 13, an MBR membrane zone 14, and a clear water zone 15 connected sequentially along the water flow direction. The shell 1 also contains an equipment area 16, wherein the aerobic zone 13 contains a suspended carrier. The first aeration component 2 is disposed at the bottom of the aerobic zone 13. The purging component 3 is disposed at the bottom of the aerobic zone 13 and above the first aeration component 2, and the airflow of the purging component 3 is greater than the airflow of the first aeration component 2. The blower component 4 is disposed in the equipment area 16 and is connected to both the first aeration component 2 and the purging component 3 to supply air to both components.
[0024] In this embodiment, please refer to Figure 1 and Figure 2The housing 1 is movable. The housing 1 contains an anaerobic zone 11, an anoxic zone 12, an aerobic zone 13, an MBR membrane zone 14, a clear water zone 15, and an equipment zone 16. The equipment zone 16 is used for installing corresponding equipment. The bottom of the aerobic zone 13 is equipped with a first aeration component 2 for aeration. At the bottom of the aerobic zone 13 and above the first aeration component 2, a purging component 3 is also provided. The airflow of the purging component 3 is greater than that of the first aeration component 2, thereby rapidly agitating the suspended carriers at the bottom of the aerobic zone 13, preventing the suspended carriers from accumulating, avoiding blockage of the aerators, and improving the wastewater treatment efficiency of the aerobic zone 13. Furthermore, all valves, instruments, and power equipment in this application are highly integrated onto the housing 1, making installation and operation more convenient and flexible, reducing footprint, and lowering costs.
[0025] It should be noted that the anoxic zone is relative to the anaerobic and aerobic zones. Generally, it refers to a biological system where dissolved oxygen is controlled between 0.2-0.5 mg / L. The anoxic zone is a reaction tank without dissolved oxygen but containing nitrates. Hydrolysis occurs in the anoxic zone, and in the denitrification process, its pH value increases. In the denitrification process, it mainly plays a role in denitrification to remove nitrate nitrogen, while also removing some BOD. The hydrolysis reaction also improves biodegradability. The anaerobic zone is where wastewater is degraded into simple inorganic substances by anaerobic microorganisms under anaerobic conditions; its dissolved oxygen is 0.
[0026] In this embodiment, the housing 1 has a cavity, and a plurality of partitions 18 spaced apart along the direction of the housing 1 are arranged in the cavity, thereby dividing the cavity into the anaerobic zone 11, the anoxic zone 12, the aerobic zone 13, the MBR membrane zone 14, and the clear water zone 15. Each partition 18 is provided with a water passage hole, thereby connecting the reaction zones. Specifically, the water passage hole on the partition 18 between the anaerobic zone 11 and the anoxic zone 12 is located at the top, the water passage hole on the partition 18 between the anoxic zone 12 and the aerobic zone 13 is located at the bottom, the water passage hole on the partition 18 between the aerobic zone 13 and the MBR membrane zone 14 is located at the top, and the water passage hole on the partition 18 between the MBR membrane zone 14 and the clear water zone 15 is located at the top.
[0027] In this embodiment, a certain number of spherical suspended carriers are filled in the aerobic zone 13, which increases the biomass and species in the aerobic zone 13, thereby improving the wastewater treatment efficiency of the aerobic zone 13. Since the density of the suspended carriers in the aerobic zone 13 is close to that of water, the suspended carriers are completely mixed with water during aeration, and the microorganisms are in a three-phase growth environment of gas, liquid, and solid. The collision and shearing action of the suspended carriers in the water makes the air bubbles smaller, improving the utilization rate of oxygen. In addition, each suspended carrier has different species inside and outside, with some anaerobic or facultative anaerobic bacteria inside and aerobic bacteria outside, making each suspended carrier similar to a micro-reactor, so that nitrification and denitrification reactions exist simultaneously, thereby enhancing the treatment effect.
[0028] In one embodiment, please refer to Figure 1 and Figure 3 The first aeration component 2 includes a plurality of first aeration discs 21, which are arranged in an array at the bottom of the aerobic zone 13 and facing downwards. The first aeration discs 21 are connected to the blower component 4.
[0029] In this embodiment, the first aeration assembly 2 includes a plurality of first aeration pipes 22 and two second aeration pipes 23. The plurality of first aeration pipes 22 are spaced apart along the width direction of the housing 1. Each first aeration pipe 22 is provided with a downwardly facing mounting hole for mounting a first aeration disc 21. The plurality of first aeration discs 21 are mounted on the plurality of first aeration pipes 22. The two aeration pipes are spaced apart along the length direction of the housing 1. The two second aeration pipes 23 are respectively connected to the two ends of the plurality of first aeration pipes 22, thereby enabling the plurality of first aeration pipes 22 to communicate with each other. One of the first aeration pipes 22 is connected to the blower assembly 4. By setting the first aeration discs 21 to be mounted downwards, clogging of the first aeration discs 21 can be further avoided.
[0030] It should be noted that the first aeration disc 21 is existing technology and will not be described in detail here.
[0031] In one embodiment, please refer to Figure 1 and Figure 4 The purging assembly 3 includes a plurality of purging pipes 31, which are spaced apart and connected to the blower assembly 4. Each purging pipe 31 is provided with a plurality of purging holes 32 spaced apart along its axial direction. The diameter of the purging holes 32 is smaller than the diameter of the aeration holes of the first aeration assembly 2.
[0032] In this embodiment, a plurality of purge pipes 31 are spaced apart along the width direction of the housing 1. One end of each purge pipe 31 is blocked, and the other end of each purge pipe 31 is connected to a connecting pipe. The connecting pipe is connected to the blower assembly 4. Furthermore, the diameter of each purge hole 32 is smaller than the diameter of the aeration hole of the first aeration disc 21, thereby providing a strong purge airflow to prevent suspended carriers from accumulating and clogging the first aeration disc 21 at the bottom of the aerobic zone 13.
[0033] The specific arrangement of the multiple purge pipes 31 is not limited. It can be that the multiple purge pipes 31 correspond one-to-one with the multiple first aeration pipes 22, with each purge pipe 31 located above the first aeration pipe 22. Alternatively, the purge pipes 31 can be located between two adjacent first aeration pipes 22.
[0034] The orientation of the purge hole 32 is not limited. The purge hole 32 can be set upward or downward, and can be selected according to the actual situation.
[0035] In another embodiment, the purge pipe 31 includes a first pipe body, a second pipe body, and a driving device. One end of the first pipe body is sealed, and the other end of the first pipe body is connected to the blower assembly 4. The upper and lower sides of the first pipe body are provided with elongated holes that communicate with its cavity. The elongated holes extend along its axial direction. The second pipe body is adapted to the first pipe body, that is, the inner diameter of the second pipe body is the same as the outer diameter of the first pipe body. The second pipe body is rotatably sleeved on the outer periphery of the first pipe body. The purge hole 32 is provided in the second pipe body so that when the second pipe body rotates, the purge hole 32 can be connected to one of the two elongated holes to change the purge direction. The driving device is connected to the second pipe body to drive the second pipe body to rotate.
[0036] The blowing direction can be adjusted by rotating the second tube. When suspended carriers accumulate in the area below the blowing tube 31, the driving device drives the second tube to rotate, so that the blowing hole 32 is connected to the elongated hole located below. At this time, the blowing direction is set downward. When suspended carriers accumulate in the area above the blowing tube 31, the driving device drives the second tube to rotate, so that the blowing hole 32 is connected to the elongated hole located above. At this time, the blowing direction is set upward.
[0037] Specifically, the driving device includes a mounting plate, a gear, a gear ring, and a drive motor. The mounting plate is fixedly mounted on one end of the first tube body, the gear is rotatably mounted on the mounting plate, the gear ring is located on the outer periphery of the second tube body and meshes with the gear, and the drive motor is connected to the gear to drive the gear to rotate.
[0038] In one embodiment, please refer to Figure 1 An interceptor 17 is provided between the anoxic zone 12 and the aerobic zone 13, and between the aerobic zone 13 and the MBR membrane zone 14. The interceptor 17 has a box structure with one side open. The open side of the interceptor 17 is connected to the anoxic zone 12 or the aerobic zone 13. The other sides of the interceptor 17 are provided with a plurality of water passage holes. The diameter of the water passage holes is smaller than the diameter of the suspended carrier.
[0039] In this embodiment, since the anaerobic zone 11, the anoxic zone 12, the aerobic zone 13, the MBR membrane zone 14, and the clear water zone 15 are sequentially connected, and the aerobic zone 13 is filled with suspended carriers, to prevent the suspended carriers from entering the anoxic zone 12 and the MBR membrane zone 14, interceptors 17 are provided at the water passage holes on the two partitions 18 corresponding to the aerobic zone 13. On the partition 18 between the anoxic zone 12 and the aerobic zone 13, the opening side of the interceptor 17 faces the anoxic zone 12, and on the partition 18 between the aerobic zone 13 and the MBR membrane zone 14, the opening side of the interceptor 17 faces the aerobic zone 13. Furthermore, the diameter of the water passage hole of the interceptor 17 is smaller than the diameter of the suspended carriers, thereby intercepting the suspended carriers and preventing them from entering the anoxic zone 12 and the MBR membrane zone 14.
[0040] In one embodiment, please refer to Figure 1 The MBR membrane zone 14 is also equipped with an MBR membrane module 5; the mobile integrated sewage treatment equipment also includes a second aeration module 6, which is located at the bottom of the MBR membrane zone 14, and the blower module 4 is connected to the second aeration module 6.
[0041] In this embodiment, the MBR membrane module 5 includes a membrane structure 51. The equipment area also includes an MBR permeate pump 52 and an ultraviolet sterilizer 53. The clear water area also includes an MBR flushing pump. The membrane structure 51 is located within the MBR membrane zone 14 and is capable of filtering wastewater. The MBR permeate pump 52 is installed in the equipment zone 16. The inlet of the MBR permeate pump 52 is connected to the interior of the membrane structure 51 via a pipe, and the outlet of the MBR permeate pump 52 is connected to the inlet of the ultraviolet sterilizer 53. The outlet of the ultraviolet sterilizer 53 is connected to the clear water zone 15. The MBR flushing pump 54 is located in the clear water zone 15, and its outlet is connected to the membrane structure 51. In actual use, the slight negative pressure generated by the MBR permeate pump 52 is used to extract the wastewater to be treated from the membrane structure 51. The filtration direction is from the outside to the inside of the membrane fibers. The membrane structure 51 operates intermittently, typically running continuously for 8 minutes, pausing for 1 minute, and then undergoing periodic backwashing for 1 minute. The MBR permeate pump 52 will then... Water is delivered to the clear water zone 15. A portion of the permeate in the clear water zone 15 is then pumped back to the membrane structure 51 via the MBR flushing pump 54 for membrane backwashing or cleaning. During operation, suspended solids and colloidal substances gradually accumulate on the outer surface of the membrane fibers in the membrane structure 51, causing a decrease in membrane flux and a continuous increase in membrane filtration resistance. At this point, periodic backwashing is necessary. This can be restored by using the permeate from the membrane structure 51 to backwash the membrane fibers from the inside out. A high-flow-rate, low-head water flow is used to flush away fouling substances from the membrane surface. The washing cycle is usually once every 2 hours, and the backwashing time is 40-60 seconds. The backwashing cycle and backwashing time can be adjusted according to the water quality. The backwashing direction is opposite to the water production direction of the membrane system. The second aeration component 6 is an energy-saving pulse aeration system. Air is introduced into the pulse aerator at the bottom of the membrane element through the pipeline and released intermittently. The released bubbles mix with the liquid during the rising process and form a vortex on the membrane surface. The rising air scrubs and cleans the outer surface of the hollow fiber membrane, delays membrane fouling, thereby extending the service life of the membrane element, improving filtration efficiency, and significantly saving operation and maintenance costs.
[0042] In one embodiment, please refer to Figure 1 The blower assembly 4 is connected to the first aeration assembly 2 through a first pipe, and a first valve assembly is provided on the first pipe. The blower assembly 4 is connected to the purging assembly 3 through a second pipe, and a second valve assembly is provided on the second pipe. The blower assembly 4 is connected to the second aeration assembly 6 through a third pipe, and a third valve assembly is provided on the third pipe.
[0043] In this embodiment, the first valve assembly can control the opening and closing of the first pipe and adjust the flow rate of the first pipe, thereby controlling the air volume of the first aeration assembly 2; the second valve assembly can control the opening and closing of the second pipe and adjust the flow rate of the second pipe, thereby controlling the air volume of the purging assembly 3; and the third valve assembly can control the opening and closing of the third pipe and adjust the flow rate of the third pipe, thereby controlling the air volume of the second aeration assembly 6.
[0044] In one embodiment, please refer to Figure 1 The mobile integrated wastewater treatment equipment also includes an MBR reflux pump 7, which is located in the equipment area 16. The inlet of the MBR reflux pump 7 is connected to the MBR membrane area 14, and the outlet of the MBR reflux pump 7 is connected to the aerobic area 13 and the outside.
[0045] In this embodiment, the MBR reflux pump 7 can also serve as a residual sludge discharge pump. It first draws from the MBR membrane zone 14 and returns the residual sludge to the aerobic zone 13, so that the amount of sludge in the aerobic zone 13 meets the requirements for the reproduction of aerobic microorganisms, thereby enhancing the aerobic treatment effect. Another part of the sludge can be discharged through the discharge pipe of the MBR reflux pump 7 to ensure the discharge of total phosphorus in the system.
[0046] In one embodiment, please refer to Figure 1 The mobile integrated sewage treatment equipment also includes a nitrification liquid return pump 8, which is located in the equipment area 16. The inlet of the nitrification liquid return pump 8 is connected to the aerobic zone 13, and the outlet of the nitrification liquid return pump 8 is connected to the anoxic zone 12. An interceptor 17 is provided at the inlet of the nitrification liquid return pump 8.
[0047] In this embodiment, the inlet of the nitrification liquid return pump 8 is equipped with an anti-clogging interceptor 17, which can prevent the suspended carrier in the aerobic zone 13 from being sucked into the pump body. The nitrification liquid is drawn into the anoxic zone 12 by the nitrification liquid return pump 8, providing a large amount of nitrate nitrogen for the denitrification reaction. The nitrate nitrogen is converted into nitrogen gas, which better completes the biochemical reaction process of nitrogen and phosphorus removal.
[0048] In one embodiment, please refer to Figure 1 Both the anaerobic zone 11 and the anoxic zone 12 are equipped with stirring devices 9.
[0049] In this embodiment, by setting a stirring device 9 in the anaerobic zone 11, the wastewater is mixed more evenly after stirring, which improves the efficiency of the anaerobic reaction. After the anaerobic reaction, the wastewater enters the anoxic zone 12 through the water passage for further reaction. Some facultative anaerobic bacteria grow inside the anoxic zone 12. By setting a stirring device 9, the wastewater is completely mixed, which further improves the treatment efficiency of the anoxic zone 12. The wastewater is then supplied to the aerobic zone 13 after undergoing the facultative anaerobic reaction.
[0050] In this embodiment, the shell 1 is also provided with a phosphorus removal dosing port that connects to the clear water zone 15. By providing the phosphorus removal dosing port, the phosphorus removal effect can be ensured, so as to guarantee that the total phosphorus in the system's produced water meets the technical requirements.
[0051] This application integrates valves, instruments, and power equipment onto the housing 1, making installation and operation more convenient and flexible, reducing footprint, and saving investment.
[0052] This application provides a second aeration component 6 within the MBR membrane zone 14, which facilitates the blowing away of sludge from the MBR membrane module 5, reduces membrane clogging, and improves the MBR water production rate and service life.
[0053] The aerobic zone 13 described in this application is equipped with a purging component 3, which makes it difficult for suspended carriers to accumulate and clog the first aeration component 2, thereby improving the wastewater treatment efficiency of the aerobic zone 13.
[0054] The aerobic zone 13 described in this application is equipped with an interceptor 17 to prevent suspended carriers from overflowing. This prevents suspended carriers from entering other reaction zones through water passages and water pumps, thereby causing the loss of packing material and reducing wastewater treatment efficiency.
[0055] This application also includes a phosphorus removal dosing port, which can automatically add phosphorus removal agents as needed to ensure that the total phosphorus content in the produced water meets the standards.
[0056] The specific embodiments of the present invention described above do not constitute a limitation on the scope of protection of the present invention. Any other corresponding changes and modifications made in accordance with the technical concept of the present invention should be included within the scope of protection of the claims of the present invention.
