Description

Technical Field

[0001] This utility model relates to the technical field of water environment management, specifically to an integrated nanofiltration device for water environment management. Background Technology

[0002] An integrated nanofiltration system is a water purification device that integrates nanofiltration technology. It combines the advantages of nanomaterials and filtration technology, using nanoscale pores to screen and separate tiny particles in liquids, thereby purifying and improving water quality. The working principle of the integrated nanofiltration system is mainly based on nanoscale fluid dynamics and the principle of molecular selective separation. When liquid passes through the nanofilter, particles larger than the nanopore size are filtered out by the nanofiltration membrane; after a certain period of filtration, the nanofiltration membrane will become saturated and clogged.

[0003] Existing integrated nanofiltration equipment typically uses backwashing to restore its filtration performance when it becomes clogged after prolonged use. However, if the wastewater generated by backwashing is not properly treated, it can easily lead to water waste and even secondary pollution of the water environment. Therefore, we need to propose an integrated nanofiltration equipment for water environment management. Utility Model Content

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] Please see Figure 1-4 This utility model provides a technical solution: an integrated nanofiltration device for water environment treatment, comprising a filter body 1, an inlet pipe 2 connected to one side of the filter body 1, a processing component for improving wastewater treatment efficiency installed on the other side of the filter body 1, a circulation component for improving water resource utilization installed on one side of the processing component, and a cleaning component for improving sludge treatment efficiency installed at the bottom of the processing component. Water to be treated can be introduced into the filter body 1 through the inlet pipe 2 for efficient filtration.

[0022] The processing assembly includes a sewage pipe 3, one end of which is connected to one side of the filter equipment body 1. A sewage valve 4 is installed at the end of the sewage pipe 3 closest to the filter equipment body 1. The processing assembly also includes a sedimentation tank 5 connected to the sewage pipe 3. A top cover 6 is installed on the top of the sedimentation tank 5, and a reagent box 7 is installed at the bottom of the top cover 6. A control valve 8 is installed on the surface of the reagent box 7. The sewage pipe 3 connects the filter equipment body 1 and the sedimentation tank 5. Wastewater generated in the filter equipment body 1 due to backwashing is transferred to the sedimentation tank 5 through the sewage pipe 3 for further treatment. With the sewage valve 4, the discharge rate of the wastewater can be precisely controlled to ensure that the wastewater can enter the sedimentation tank 5 smoothly and orderly, thereby improving the wastewater treatment efficiency. By setting the top cover 6, the internal environment of the sedimentation tank 5 can be protected, preventing external impurities from entering the sedimentation tank 5 and affecting the wastewater treatment effect. At the same time, it also facilitates the maintenance and repair of the sedimentation tank 5 by the staff. Through the cooperation of the reagent box 7 and the control valve 8, the amount of reagent (flocculator) in the reagent box 7 can be controlled to ensure that the reagent is added to the wastewater at an appropriate flow rate and speed, avoiding over- or under-dosing. The flocculant can accelerate the aggregation of suspended particulate matter or colloidal substances in the wastewater, making them form larger particles more quickly, and thus more easily separated from the wastewater by physical sedimentation.

[0023] A water quality analyzer 9 is installed on one side of the inner wall of sedimentation tank 5, and a sludge interface meter 10 is installed on the other side of the inner wall of sedimentation tank 5. A sludge hopper 11 is installed at the bottom of sedimentation tank 5, and a sludge pump 12 is installed at the bottom of sludge hopper 11. Real-time data from the water quality analyzer 9 allows for precise control of the dosage of chemicals, preventing over- or under-dosing and thus improving the efficiency and effectiveness of wastewater treatment. The sludge interface meter 10, installed on the other side of the inner wall of sedimentation tank 5, monitors the interface between sludge and clean water, i.e., the height of the sludge layer. The sludge hopper 11, installed at the bottom of sedimentation tank 5, primarily collects and stores the sludge deposited after sedimentation. Through physical sedimentation, suspended particles and heavy impurities in the wastewater gradually settle to the bottom of sedimentation tank 5.

[0024] The circulation assembly includes a first pipe 13 and a circulation tank 14. One end of the first pipe 13 is connected to one side of the sedimentation tank 5, and one side of the circulation tank 14 is connected to one end of the first pipe 13. A water level gauge 15 is installed on the inner wall of the circulation tank 14. A second pipe 16 is connected to the bottom of the circulation tank 14. A water pump 17 is connected to the end of the second pipe 16 away from the circulation tank 14. A third pipe 18 is connected to the drain outlet of the water pump 17. The end of the third pipe 18 away from the water pump 17 is connected to the inlet of the filter equipment body 1. Wastewater generated by backwashing of the filter equipment body 1 is discharged into the sedimentation tank 5 for sedimentation treatment, and then flows into the interior of the circulation tank 14 through the first pipe 13. The water level gauge 15 installed on the inner wall of the circulation tank 14 can monitor the water level in the circulation tank 14 in real time. When the water level reaches the threshold, the water pump 17 is started to pump the water in the circulation tank 14 out through the second pipe 16 and discharge it to the inlet of the filter equipment body 1 through the third pipe 18, so that it can be further recycled and reused, effectively reducing the waste of water resources.

[0025] The cleaning assembly includes a sludge discharge pipe 19 and a sludge tank 20. One end of the sludge discharge pipe 19 is connected to the sludge discharge port of the sludge discharge pump 12, and one side of the sludge tank 20 is connected to one end of the sludge discharge pipe 19. A sludge door 21 is installed on the front of the sludge tank 20, and a first handle 22 is installed on the surface of the sludge door 21. A sludge bucket 23 is installed inside the sludge tank 20, and a second handle 24 is installed on the surface of the sludge bucket 23. The sludge interface meter 10 installed on the inner wall of sedimentation tank 5 monitors the interface position between sludge and clean water in real time. When the sludge height reaches a threshold, the sludge discharge pump 12 is activated to discharge the sludge on the surface of sludge hopper 11 through sludge discharge pipe 19 into sludge bucket 23 inside sludge tank 20. The sludge accumulated in sludge hopper 11 at the bottom of sedimentation tank 5 is efficiently discharged through sludge discharge pipe 19, avoiding long-term sludge retention in the equipment and reducing the potential for equipment blockage or decreased operating efficiency due to sludge accumulation. By pulling the first handle 22 to open sludge door 21, and then pulling the second handle 24, sludge bucket 23 can be pulled out to remove the sludge for further processing. Through the regular operation of the cleaning components, the equipment can be kept in good operating condition, ensuring the efficiency and effectiveness of the nanofiltration equipment in treating wastewater.

[0026] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
