Technical Field

[0001] The utility model relates to the technical field of waste liquid treatment equipment, and more specifically, to a waste liquid treatment device. Background Art

[0002] Aluminum product processing wastewater mainly includes cutting fluid, cleaning fluid, alkali solution, etc. These wastewaters contain a large amount of harmful substances such as grease, metal ions, organic additives, etc. If these wastewaters are directly discharged into the environment, they will cause great harm to aquatic organisms and human health. Therefore, aluminum product processing wastewater needs to be effectively treated before it can be discharged.

[0003] Among them, one of the commonly used wastewater treatment methods is the chemical precipitation method. This method adds chemical agents to the wastewater to make the harmful substances in the wastewater react with the agents to form precipitates, thereby removing the harmful substances. However, the chemical precipitation method has some disadvantages, such as the need to use a large amount of chemical agents and the difficulty in treating the precipitates. Therefore, in view of the above problems, a waste liquid treatment device is specially proposed. Utility Model Content

Under the joint action of the first motor 7, the bidirectional threaded rod 5, the scrapers 6 and the sewage trough 18, the first motor drives the bidirectional threaded rod 5 to rotate, and can drive the scrapers 6 to move toward the sewage trough 18, so that the precipitated sediment can be discharged from the sedimentation tank 2 through the sewage trough 18. The sedimentation tank 2 is connected with a first water pipe 8, and the first water pipe 8 is connected with the input end of the first water pump 9. The output end of the first water pump 9 is connected with a second water pipe 10, and the other end of the second water pipe 10 is connected with a filter tank 24.

[0029] A mounting frame 26 is adjustably connected in the filter pool 24, and a tooth plate 12 is fixedly connected to one side of the mounting frame 26. A second motor 25 is fixedly connected to the filter pool 24 through a fixing plate, and a gear 13 is fixedly connected to the output shaft of the second motor 25, and the gear 13 is meshed with the tooth plate 12. A PP cotton filter layer 21, a granular activated carbon filter layer 22 and a compressed activated carbon layer 23 are installed in the mounting frame 26, and its installation method is the existing technology, such as a snap-on method. Under the joint action of the second motor 25, the gear 13, the tooth plate 12 and the mounting frame 26, the second motor 25 can move the mounting frame 26 upward to expose the filter layer on the mounting frame to the filter pool, so that the PP cotton filter layer 21, the granular activated carbon filter layer 22 and the compressed activated carbon layer 23 on the mounting frame 26 can be replaced. One side of the filter pool 24 is connected to an ultrafiltration filtering mechanism 14 through a connecting pipe. The filtering mechanism 14 is connected to a nanofiltration filtering mechanism 16 through a third water pipe 15, and the nanofiltration filtering mechanism 16 is connected to a second water pump 17. Under the action of the second water pump 17, the water filtered in the nanofiltration filtering mechanism 16 can be discharged. Under the joint action of the sedimentation tank 2, the filter tank 24, the ultrafiltration filtering mechanism 14 and the nanofiltration filtering mechanism 16, the wastewater generated by the aluminum product processing enters the sedimentation tank 2 through the water inlet pipe 1 for precipitation. Under the action of the first water pump 9, the supernatant generated by the precipitation in the sedimentation tank 2 enters the filter tank 24 to filter out larger suspended matter in the waste liquid and remove the odor in the waste liquid. After filtering by the ultrafiltration filtering mechanism 14, suspended matter, large molecular organic matter, metal ions and other harmful substances in the waste water can be removed. After filtering by the nanofiltration filtering mechanism 16, small molecular organic matter, heavy metal ions and other harmful substances in the waste water can be removed, thereby treating the waste water to obtain water that can be discharged.

[0031] The working principle of the utility model is as follows: the water inlet pipe 1 is connected to the external conveying mechanism. When the wastewater is treated, the wastewater enters the sedimentation tank 2 through the water inlet pipe 1. The wastewater is precipitated through the primary sedimentation chamber 2, and its supernatant enters the secondary sedimentation chamber 2 through the overflow tank. The supernatant of the secondary sedimentation chamber 2 enters the filter tank 24 under the action of the first water pump 9. After filtering through the PP cotton filter layer 21, the granular activated carbon filter layer 22 and the compressed activated carbon layer 23, larger suspended matter in the wastewater and odor can be removed. The filtered wastewater enters the ultrafiltration filter mechanism 14 and the nanofiltration filter mechanism 16 for filtration. Under the action of the second water pump, wastewater that meets the discharge standard can be obtained.

[0032] When the sediment in the sedimentation tank 2 needs to be cleaned, the conveying mechanism stops conveying wastewater, and then the sewage chute 18 is opened. The controller controls the first motor 7 to rotate with the bidirectional threaded rod 5, and under the limit of the chute 4, the two scrapers 6 scrape the bottom of the primary sedimentation chamber 19 and the secondary sedimentation chamber 20, so that the sediment at the bottom is discharged from the sedimentation tank through the sewage chute 18;

[0033] It is necessary to replace the PP cotton filter layer 21, the granular activated carbon filter layer 22 and the compressed activated carbon layer 23 in the filter pool 24, and the controller controls the second motor 25 to rotate the gear 13, and the gear 13 rotates in meshing with the tooth plate 12, and the mounting frame 26 is raised to a certain height, and then the PP cotton filter layer 21, the granular activated carbon filter layer 22 and the compressed activated carbon layer 23 are conveniently removed from the mounting frame 26 and installed with new ones.
