Description

Technical Field

[0001] This utility model relates to the technical field of DTRO landfill leachate treatment equipment, specifically a landfill leachate membrane filtration treatment system. Background Technology

[0002] Landfill leachate treatment equipment is an industrial device used to treat leachate, mainly for high-concentration organic wastewater. It is characterized by high BOD5 / COD concentration, high metal content, high ammonia nitrogen content, large fluctuations in water quality and quantity, and imbalance of microbial nutrient elements.

[0003] The DTRO landfill leachate treatment equipment adopts a combination of physical-chemical (pretreatment) + biological (anaerobic + aerobic) + physical-chemical (deep treatment) processes. During the treatment process, DTRO membrane technology is used for deep treatment, which can remove high-valence metal ions and color.

[0004] Existing DTRO landfill leachate treatment equipment typically has multiple DTRO membranes. After installation, the clean water port, wastewater port, and concentrate port at the bottom of the DTRO membrane need to be connected to the corresponding main pipeline using connecting pipes to allow wastewater to enter the DTRO membrane and the produced concentrate and clean water to flow out. This makes the installation of the DTRO membrane quite troublesome, and the corresponding valves need to be closed during installation and disassembly. Utility Model Content

[0005] The purpose of this invention is to provide a landfill leachate membrane filtration treatment system to solve the problems in the prior art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a landfill leachate membrane filtration treatment system, comprising a pipe and a DTRO leachate membrane. The pipe has a square cross-section, with a clear water channel at the center of the pipe's interior. A wastewater channel and a concentrated water channel are respectively opened on both sides of the clear water channel. Multiple leachate membrane stabilizing sleeves are fixed at equal intervals on the top surface of the pipe. Three connector mounting slots are respectively opened on the top surface of the pipe inside the leachate membrane stabilizing sleeves, communicating with the clear water channel, wastewater channel, and concentrated water channel. A leachate membrane connector is installed in the connector mounting slot. The DTRO leachate membrane is inserted and installed on the leachate membrane stabilizing sleeve. The clear water port, wastewater port, and concentrated water port at the bottom of the DTRO leachate membrane are respectively connected to the clear water channel, wastewater channel, and concentrated water channel through corresponding leachate membrane connectors. The leachate membrane connector connects after being inserted into the port at the bottom of the DTRO leachate membrane and closes after being withdrawn from the port at the bottom of the DTRO leachate membrane.

[0007] Preferably, the percolation membrane connector consists of a connector housing, a sealing head, and a spring. The connector housing has an inlet at the top and an outlet at the bottom. The sealing head is a bottom-open columnar structure with multiple equally spaced communication ports on its top surface. The sealing head is installed inside the connector housing, and the spring is installed inside the connector housing and at the bottom of the sealing head. The clear water port, wastewater port, and concentrated water port at the bottom of the DTRO percolation membrane all allow for side liquid flow.

[0008] Preferably, the outer surface of the connector housing is provided with external threads, and the inner wall of the connector mounting groove is provided with internal threads.

[0009] Preferably, the inner wall of the percolate membrane stabilizing sleeve is provided with a vertical positioning groove, and the lower part of the outer side of the DTRO percolate membrane is provided with a vertical positioning protrusion.

[0010] Preferably, each side of the leachate membrane stabilizing sleeve is provided with a locking mechanism. The locking mechanism consists of a rod, a locking block and a nut. The rod is vertically installed on the pipeline. The locking block is sleeved on the upper part of the rod and limited by the nut. Two limiting plates that cooperate with the locking mechanism are fixed on the lower part of the outer side of the DTRO leachate membrane.

[0011] Preferably, the pipe is provided with mounting holes for mounting the rod.

[0012] Compared with the prior art, the beneficial effects of this utility model are: the pipeline has a clear water channel, a sewage channel and a concentrated water channel at the same time, which makes the pipeline laying simpler. The cross-section of the pipeline is a flat square, so that the flat top surface of the pipeline can serve as a platform to support the DTRO permeate membrane. The three permeate membrane connectors installed at the top of the pipeline connect to the clear water channel, the sewage channel and the concentrated water channel respectively. The three permeate membrane connectors are used to connect to the clear water port, sewage port and concentrated water port at the bottom of the DTRO permeate membrane. The above structure makes it possible to install the DTRO permeate membrane without the need for additional pipeline connection. At the same time, since the permeate membrane connector has the function of connecting the DTRO permeate membrane port at the insertion port and closing it after being pulled out, it is possible to install the DTRO permeate membrane without closing the valve in advance.

[0013] The permeate membrane connector consists of a connector housing, a sealing head, and a spring. When the port of the DTRO permeate membrane is inserted into the inlet of the permeate membrane connector, it squeezes the sealing head, causing the sealing head to move downward a certain distance, thus opening the permeate membrane connector. At this time, the liquid enters the DTRO permeate membrane upward through the connecting port on the sealing head, or flows downward out of the DTRO permeate membrane. When the port of the DTRO permeate membrane is withdrawn from the inlet of the permeate membrane connector, the spring pushes the sealing head upward and seals the inlet of the permeate membrane connector, thus closing the permeate membrane connector.

[0014] The locking mechanism works in conjunction with the limiting plate on the DTRO permeate membrane. After the DTRO permeate membrane is installed, the locking block is rotated to press down the limiting plate, which can keep the connection between the bottom port of the DTRO permeate membrane and the permeate membrane connector tight.

Obviously, the described embodiments are only a part of the embodiments of this utility model, not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model. Therefore, the following detailed description of the embodiments of this utility model provided in the accompanying drawings is not intended to limit the scope of the claimed utility model, but merely represents selected embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0024] Please see Figure 1-6 In this embodiment of the present invention, a landfill leachate membrane filtration treatment system includes a pipe 1 and a DTRO leachate membrane 7. The pipe 1 has a square cross-section. A clear water channel 3 is opened at the center of the pipe 1. A sewage channel 2 and a concentrated water channel 4 are opened on both sides of the clear water channel 3, respectively. Multiple leachate membrane stabilizing sleeves 6 are fixed at equal intervals on the top surface of the pipe 1. Three connector mounting grooves 13 are opened on the top surface of the pipe 1 inside the leachate membrane stabilizing sleeves 6, respectively communicating with the clear water channel 3, the sewage channel 2, and the concentrated water channel 4. A leachate membrane connector 9 is installed in the connector mounting groove 13. The DTRO leachate membrane 7 is inserted and installed on the leachate membrane stabilizing sleeve 6. The clear water port, sewage port, and concentrated water port at the bottom of the DTRO leachate membrane 7 are respectively connected to the clear water channel 3, the sewage channel 2, and the concentrated water channel 4 through the leachate membrane connectors 9 at corresponding positions. The port at the bottom of the TRO permeate membrane 7 is connected after insertion and closed after extraction. The pipe 1 has a clear water channel 3, a wastewater channel 2, and a concentrate channel 4, which simplifies the installation of the pipe 1. The cross-section of the pipe 1 is a flat square, so that the flat top surface of the pipe 1 can serve as a platform to support the DTRO permeate membrane 7. The three permeate membrane connectors 9 installed on the top of the pipe 1 are connected to the clear water channel 3, the wastewater channel 2, and the concentrate channel 4, respectively. The three permeate membrane connectors 9 are used to connect to the clear water port, wastewater port, and concentrate port at the bottom of the DTRO permeate membrane 7. The above structure means that the DTRO permeate membrane 7 does not require additional pipe connections during installation. At the same time, since the permeate membrane connectors 9 have the function of connecting the port of the DTRO permeate membrane 7 at the insertion port and closing after extraction, the valve of the DTRO permeate membrane 7 does not need to be closed in advance during disassembly and assembly.

[0025] The percolation membrane connector 9 consists of a connector housing 15, a sealing head 16, and a spring 17. The connector housing 15 has an inlet at the top and an outlet at the bottom. The sealing head 16 is a bottom-open cylindrical structure with multiple equally spaced connecting ports 18 on its top surface. The sealing head 16 is installed inside the connector housing 15. The spring 17 is installed inside the connector housing 15 and located at the bottom of the sealing head 16. The clear water port, wastewater port, and concentrated water port at the bottom of the DTRO percolation membrane 7 all allow for side liquid flow. The percolation membrane connector 9 consists of a connector housing 15, a sealing head 16, and a spring 17. The shell 15, the plug head 16, and the spring 17 are used to press the plug head 16 when the port of the DTRO permeate membrane 7 is inserted into the inlet of the permeate membrane connector 9, causing the plug head 16 to move downward a certain distance, thus opening the permeate membrane connector 9. At this time, the liquid enters the DTRO permeate membrane 7 upward through the connecting port 18 on the plug head 16, or flows downward out of the DTRO permeate membrane 7. When the port of the DTRO permeate membrane 7 is withdrawn from the inlet of the permeate membrane connector 9, the spring 17 pushes the plug head 16 upward and seals the inlet of the permeate membrane connector 9, thus closing the permeate membrane connector 9.

[0026] The outer surface of the connector housing 15 is provided with external threads, and the inner wall of the connector mounting groove 13 is provided with internal threads. The percolation membrane connector 9 is fixed to the pipe 1 by threaded connection.

[0027] The inner wall of the leachate membrane stabilizing sleeve 6 is provided with a vertical positioning groove 20, and the lower part of the outer side of the DTRO leachate membrane 7 is provided with a vertical positioning protrusion 19. The positioning groove 20 and the positioning protrusion 19 cooperate to play a positioning role, preventing the DTRO leachate membrane 7 from being installed at an incorrect angle, which would cause the bottom port of the DTRO leachate membrane 7 to not be accurately connected to the leachate membrane connector 9.

[0028] Each side of the leachate membrane stabilizing sleeve 6 is provided with a locking mechanism 5. The locking mechanism 5 consists of a rod 10, a locking block 11 and a nut 12. The rod 10 is vertically installed on the pipe 1. The locking block 11 is sleeved on the upper part of the rod 10 and is limited by the nut 12. Two limiting plates 8 that cooperate with the locking mechanism 5 are fixed on the lower part of the outer side of the DTRO leachate membrane 7. The pipe 1 is provided with mounting holes 14 for installing the rod 10.

[0029] The working principle of this utility model is as follows: Pipe 1 has a clear water channel 3, a sewage channel 2, and a concentrated water channel 4, which makes the laying of pipe 1 simpler. The cross-section of pipe 1 is a flat square, so that the flat top surface of pipe 1 can serve as a platform to support DTRO permeate membrane 7. Three permeate membrane connectors 9 installed on the top of pipe 1 are connected to the clear water channel 3, the sewage channel 2, and the concentrated water channel 4 respectively. The three permeate membrane connectors 9 are used to connect to the clear water port, sewage port, and concentrated water port at the bottom of DTRO permeate membrane 7. The above structure makes it possible to install DTRO permeate membrane 7 without the need for additional pipe connections. At the same time, since the permeate membrane connectors 9 have the function of connecting the ports of DTRO permeate membrane 7 at the insertion port and closing after being pulled out, it is possible to install DTRO permeate membrane 7 without closing the valve in advance.

[0030] The permeate membrane connector 9 consists of a connector housing 15, a sealing head 16, and a spring 17. When the port of the DTRO permeate membrane 7 is inserted into the inlet of the permeate membrane connector 9, it will squeeze the sealing head 16, causing the sealing head 16 to move downward a certain distance, thus opening the permeate membrane connector 9. At this time, the liquid enters the DTRO permeate membrane 7 upward through the connecting port 18 on the sealing head 16, or flows out of the DTRO permeate membrane 7 downward. When the port of the DTRO permeate membrane 7 is withdrawn from the inlet of the permeate membrane connector 9, the spring 17 will push the sealing head 16 upward and seal the inlet of the permeate membrane connector 9, thus closing the permeate membrane connector 9.

[0031] The locking mechanism 5 cooperates with the limiting plate 8 on the DTRO permeate membrane 7. After the DTRO permeate membrane 7 is installed, the limiting plate 8 is pressed down by rotating the locking block 11, which can keep the connection between the bottom port of the DTRO permeate membrane 7 and the permeate membrane connector 9 tight.

[0032] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
