DETAILED DESCRIPTION

[0020] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0021] In order to solve the technical problem of suspended carrier aggregation and clogging of aerators in the prior art, the present invention provides a movable integrated sewage treatment equipment, which uses the purge component to quickly disturb the suspended carriers at the bottom of the aerobic zone, making it difficult for the suspended carriers to aggregate, avoiding clogging of the aerator and improving the sewage treatment efficiency of the aerobic zone.

[0022] See also Figure 1 , Figure 1 It is a structural schematic diagram of a movable integrated sewage treatment device in one embodiment of the present invention.

[0023] The present invention provides a movable integrated sewage treatment equipment, comprising a shell 1, a first aeration component 2, a purge component 3 and a fan component 4, wherein the shell 1 is movably arranged, and an anaerobic zone 11, an anoxic zone 12, an aerobic zone 13, an MBR membrane zone 14 and a clean water zone 15 which are sequentially connected along a water flow direction are arranged in the shell 1, and the shell 1 is also provided with an equipment area 16, wherein a suspended carrier is arranged in the aerobic zone 13; the first aeration component 2 is arranged at the bottom of the aerobic zone 13; the purge component 3 is arranged at the bottom of the aerobic zone 13 and is located above the first aeration component 2, and the airflow of the purge component 3 is greater than the airflow of the first aeration component 2; the fan component 4 is arranged in the equipment area 16, and the fan component 4 is respectively connected with the first aeration component 2 and the purge component 3 to transport air to the first aeration component 2 and the purge component 3.

[0024] In this example, see Figure 1 and Figure 2The shell 1 is movable. An anaerobic zone 11, an anoxic zone 12, an aerobic zone 13, an MBR membrane zone 14, a clean water zone 15 and an equipment zone 16 are arranged in the shell 1. The equipment zone 16 is used for installation of corresponding equipment. A first aeration assembly 2 is arranged at the bottom of the aerobic zone 13 for aeration. A purge assembly 3 is arranged at the bottom of the aerobic zone 13 and above the first aeration assembly 2. The airflow of the purge assembly 3 is greater than the airflow of the first aeration assembly 2. Thus, the suspended carrier at the bottom of the aerobic zone 13 is quickly disturbed by the purge assembly 3, so that the suspended carrier is not easy to aggregate, and the aerator is avoided from being blocked, thereby improving the sewage treatment efficiency of the aerobic zone 13. In addition, all valves, instruments and power equipment of the present application are highly integrated on the shell 1, so that installation and operation are more convenient and flexible, and the space occupied and the cost are reduced.

[0025] It should be noted that the anoxic zone is relative to the anaerobic zone and the aerobic zone. It generally refers to a biochemical system where the dissolved oxygen is controlled between 0.2-0.5 mg / l. The anoxic zone refers to a reaction pool without dissolved oxygen but with nitrate. There is a hydrolysis reaction in the anoxic zone. In the denitrification process, its pH value increases. In the denitrification process, it mainly plays the role of denitrification to remove nitrate nitrogen, while removing part of the BOD, and also has the role of hydrolysis reaction to improve biodegradability. The anaerobic zone is where the sewage uses anaerobic microorganisms to degrade organic matter into simple inorganic matter under anaerobic conditions, and its dissolved oxygen is 0.

[0026] In this embodiment, a cavity is provided in the shell 1, and a plurality of partitions 18 are provided in the cavity and are arranged at intervals along the direction of the shell 1, so as to divide the cavity into the anaerobic zone 11, the anoxic zone 12, the aerobic zone 13, the MBR membrane zone 14 and the clean water zone 15. Each of the partitions 18 is provided with a water hole, so as to connect the reaction zones. Specifically, the water hole on the partition 18 between the anaerobic zone 11 and the anoxic zone 12 is located at the top, the water hole on the partition 18 between the anoxic zone 12 and the aerobic zone 13 is located at the bottom, the water hole on the partition 18 between the aerobic zone 13 and the MBR membrane zone 14 is located at the top, and the water hole on the partition 18 between the MBR membrane zone 14 and the clean 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 biological species in the aerobic zone 13, thereby improving the sewage 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 effect of the suspended carriers in the water make the air bubbles smaller, thereby improving the utilization rate of oxygen. In addition, each of the suspended carriers has different biological species inside and outside, with some anaerobic bacteria or facultative aerobic bacteria inside and aerobic bacteria outside, so that each of the suspended carriers is similar to a microreactor, allowing nitrification and denitrification reactions to exist simultaneously, thereby enhancing the treatment effect.

[0028] In one embodiment, see Figure 1 and Figure 3 The first aeration assembly 2 includes a plurality of first aeration plates 21 , which are arranged in an array at the bottom of the aerobic zone 13 and are arranged downward, and the first aeration plates 21 are connected to the fan assembly 4 .

[0029] In this embodiment, the first aeration assembly 2 includes a plurality of first aeration tubes 22 and two second aeration tubes 23. The plurality of first aeration tubes 22 are arranged at intervals along the width direction of the shell 1. Each of the first aeration tubes 22 is provided with a downwardly arranged mounting hole, and the mounting hole is used for the installation of the first aeration plate 21. The plurality of first aeration plates 21 are installed on the plurality of first aeration tubes 22. The two aeration tubes are arranged at intervals along the length direction of the shell 1. The two second aeration tubes 23 are respectively connected to the two ends of the plurality of first aeration tubes 22, so that the plurality of first aeration tubes 22 are interconnected, and one of the first aeration tubes 22 is connected to the fan assembly 4. By arranging the first aeration plate 21 to be installed downwardly, the blockage of the first aeration plate 21 can be further avoided.

[0030] It should be noted that the first aeration plate 21 is a prior art and will not be described in detail here.

[0031] In one embodiment, see Figure 1 and Figure 4 The purge assembly 3 includes a plurality of purge pipes 31, which are arranged at intervals and are all connected to the fan assembly 4. Each purge pipe 31 is provided with a plurality of purge holes 32 arranged at intervals along its axial direction, and the diameter of the purge hole 32 is smaller than the diameter of the aeration hole of the first aeration assembly 2.

[0032] In this embodiment, the plurality of purge pipes 31 are arranged at intervals along the width direction of the shell 1, one end of the purge pipe 31 is blocked, and the other ends of the plurality of purge pipes 31 are connected to a connecting pipe, and the connecting pipe is connected to the fan assembly 4, and the diameter of each of the purge holes 32 is smaller than the diameter of the aeration holes of the first aeration plate 21, so as to provide a strong purge airflow to prevent the suspended carriers from gathering at the bottom of the aerobic zone 13 and clogging the first aeration plate 21.

[0033] There is no limitation on the specific arrangement of the plurality of purge pipes 31 . The plurality of purge pipes 31 may correspond to the plurality of first aeration pipes 22 one by one, and each purge pipe 31 may be located above the first aeration pipe 22 . Alternatively, the purge pipe 31 may be located between two adjacent first aeration pipes 22 .

[0034] There is no restriction on the orientation of the purge hole 32 , and the purge hole 32 can be arranged upward or downward, which can be selected according to actual conditions.

[0035] In another embodiment, the purge tube 31 includes a first tube body, a second tube body and a driving device, one end of the first tube body is blocked, the other end of the first tube body is connected to the fan assembly 4, the upper and lower sides of the first tube body are provided with elongated holes connected to its tube cavity, and the elongated holes are extended along its axial direction, the second tube body is adapted to the first tube body, that is, the inner diameter of the second tube body is the same as the outer diameter of the first tube body, the second tube body is rotatably sleeved on the outer periphery of the first tube body, the purge hole 32 is provided in the second tube body, so that when the second tube body rotates, the purge hole 32 can be correspondingly connected to one of the two elongated holes, thereby changing the purge direction, and the driving device is connected to the second tube body to drive the second tube body to rotate.

[0036] The purging direction can be adjusted by rotating the second tube body. When the suspended carriers in the area below the purging tube 31 gather, the driving device drives the second tube body to rotate so that the purging holes 32 are correspondingly connected to the elongated holes below. At this time, the purging direction is set downward. When the suspended carriers in the area above the purging tube 31 gather, the driving device drives the second tube body to rotate so that the purging holes 32 are correspondingly connected to the elongated holes above. At this time, the purging direction is set upward.

[0037] Specifically, the driving device includes a mounting plate, a gear, a gear ring and a driving 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 arranged on the outer periphery of the second tube body and meshes with the gear, and the driving motor is connected to the gear to drive the gear to rotate.

[0038] In one embodiment, see Figure 1 An interception member 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 interception member 17 is a box structure with one side open. The open side of the interception member 17 is connected to the anoxic zone 12 or the aerobic zone 13. The remaining sides of the interception member 17 are provided with a plurality of water holes, and the diameter of the water 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 clean water zone 15 are connected in sequence, and the aerobic zone 13 is filled with suspended carriers, in order to prevent the suspended carriers from entering the anoxic zone 12 and the MBR membrane zone 14, interception members 17 are provided at the water holes on the two corresponding partitions 18 of the aerobic zone 13. On the partition 18 between the anoxic zone 12 and the aerobic zone 13, the opening side of the interception member 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 interception member 17 faces the aerobic zone 13, and the aperture of the water hole of the interception member 17 is smaller than the diameter of the suspended carrier, so that the suspended carrier can be intercepted and prevented from entering the anoxic zone 12 and the MBR membrane zone 14.

[0040] In one embodiment, see Figure 1 The MBR membrane area 14 is also provided with an MBR membrane assembly 5; the movable integrated sewage treatment equipment also includes a second aeration assembly 6, which is arranged at the bottom of the MBR membrane area 14, and the fan assembly 4 is connected to the second aeration assembly 6.

[0041] In this embodiment, the MBR membrane assembly 5 includes a membrane structure 51, the equipment area is also provided with an MBR water production pump 52 and an ultraviolet disinfector 53, and the clean water area is also provided with an MBR flushing pump. The membrane structure 51 is located in the MBR membrane area 14, and the membrane structure 51 can filter sewage. The MBR water production pump 52 is installed in the equipment area 16, and the water inlet of the MBR water production pump 52 is connected to the inside of the membrane structure 51 through a pipeline, and the water outlet of the MBR water production pump 52 is connected to the water inlet of the ultraviolet disinfector 53. The outlet of the ultraviolet disinfector 53 is connected to the clean water area 15, and the MBR flushing pump 54 is arranged in the clean water area 15. The outlet of the MBR flushing pump 54 is connected to the membrane structure 51. When in use, the sewage to be treated is extracted from the membrane structure 51 by using the slight negative pressure generated by the MBR water production pump 52. The filtering direction is from the outside of the membrane to the inside. The membrane structure 51 operates in an intermittent manner, usually continuously operating for 8 minutes, stopping for 1 minute, and then performing periodic backwashing for 1 minute. The MBR water production pump 52 removes the clean water from the membrane structure 51. The water is sent to the clean water area 15, and part of the produced water in the clean water area 15 is re-delivered to the membrane structure 51 through the MBR flushing pump 54 for membrane backwashing or cleaning. During the operation, suspended matter and colloidal substances will gradually accumulate on the outer surface of the membrane fiber of the membrane structure 51, thereby causing the membrane flux to decrease and the filtration resistance of the membrane to increase continuously. At this time, periodic backwashing is required. The produced water of the membrane structure 51 is used to reversely flush the membrane fibers from the inside to the outside to restore the membrane. The fouling substances on the membrane surface are flushed by a large flow and low head water flow. The backwashing cycle is usually once every 2 hours, and the backwashing time is 40 to 60 seconds. Both the backwashing cycle and the 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, which leads air to the pulse aerator at the bottom of the membrane element through a pipe and releases it intermittently. The released bubbles mix with the liquid during the rising process to form vortices on the membrane surface. The rising air scrubs and cleans the outer surface of the hollow fiber membrane, delaying the pollution of the membrane, thereby extending the service life of the membrane element, improving the filtration efficiency, and greatly saving operation and maintenance costs.

[0042] In one embodiment, see Figure 1 The fan 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 fan 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 component can control the opening and closing of the first pipeline and adjust the flow rate of the first pipeline, so as to control the gas volume of the first aeration component 2, the second valve component can control the opening and closing of the second pipeline and adjust the flow rate of the second pipeline, so as to control the gas volume of the purge component 3, and the third valve component can control the opening and closing of the third pipeline and adjust the flow rate of the third pipeline, so as to control the gas volume of the second aeration component 6.

[0045] In this embodiment, the MBR return pump 7 can also serve as a residual sludge discharge pump, which first draws the residual sludge from the MBR membrane zone 14 and returns it to the aerobic zone 13, so that the sludge amount in the aerobic zone 13 meets the use requirements of aerobic microbial reproduction, thereby enhancing the aerobic treatment effect. Another part of the sludge can be discharged through the sludge discharge pipe of the MBR return pump 7 to ensure the discharge of total phosphorus in the system.

[0046] In one embodiment, see Figure 1 The movable integrated sewage treatment equipment also includes a nitrification liquid reflux pump 8, which is arranged in the equipment area 16, the inlet of the nitrification liquid reflux pump 8 is connected to the aerobic zone 13, and the outlet of the nitrification liquid reflux pump 8 is connected to the anoxic zone 12, wherein an interception member 17 is provided at the inlet of the nitrification liquid reflux pump 8.

[0047] In this embodiment, an anti-clogging interception member 17 is provided at the inlet of the nitrification liquid reflux pump 8 to prevent the suspended carrier in the aerobic zone 13 from being sucked into the pump body. The nitrification liquid is sucked into the anoxic zone 12 through the nitrification liquid reflux pump 8 to provide a large amount of nitrate nitrogen for the denitrification reaction. The nitrate nitrogen is converted into nitrogen gas, thereby better completing the biochemical reaction process of denitrification and dephosphorization.

[0048] In one embodiment, see Figure 1 A stirring device 9 is provided in both the anaerobic zone 11 and the anoxic zone 12 .

[0049] In this embodiment, by providing a stirring device 9 in the anaerobic zone 11, the sewage is mixed more evenly after stirring, thereby improving the anaerobic reaction efficiency. After the anaerobic reaction, the sewage enters the anoxic zone 12 through the water hole for reaction. Some facultative anoxic bacteria grow inside the anoxic zone 12. By providing the stirring device 9, the sewage is completely mixed, thereby further improving the treatment efficiency of the anoxic zone 12, and the sewage is provided to the aerobic zone 13 after the facultative anoxic reaction.

[0050] In this embodiment, the housing 1 is further provided with a dephosphorization dosing port connected to the clean water area 15.

[0052] The present application provides a second aeration assembly 6 in the MBR membrane zone 14, which can facilitate the purge of sludge in the MBR membrane assembly 5, reduce membrane blockage, and improve the water production rate and service life of the MBR.

[0053] The aerobic zone 13 in the present application is provided with a purge assembly 3 to prevent the suspended carrier from agglomerating and clogging the first aeration assembly 2, thereby improving the sewage treatment efficiency of the aerobic zone 13 .

[0054] The aerobic zone 13 described in the present application is provided with an interception member 17 to prevent the suspended carrier from overflowing, which can prevent the suspended carrier from entering other reaction zones through the water holes and the water pump, thereby causing the loss of filler and reducing the sewage treatment efficiency.

[0055] The present application is also provided with a phosphorus removal dosing port, which can automatically add phosphorus removal agents as needed to ensure that the total phosphorus content of the produced water meets the standard.
