[0002] Aspartame, scientifically known as aspartame, is an important non-carbohydrate artificial sweetener. Aspartame is 185 to 200 times sweeter than sucrose. It is highly sweet, not easy to deliquesce, does not cause caries, and does not induce blood sugar levels in the body. Aspartame is widely used in pharmaceutical processing and food processing, such as biscuits, bread, ice cream, cakes, beverages, candies, popsicles, etc. Due to its low calorie and high sweetness, aspartame is often used as a substitute for sucrose;

[0003] A large amount of waste liquid is generated in the process of aspartame production, and the wastewater generated has high concentration and complex composition. It is a typical high-concentration difficult-to-degrade organic wastewater.

The heat exchange tube 342 is provided with a plurality of loops, which are arranged at equal intervals outside the flocculation box 2, and the heat exchange tube 342 is made of metal copper.

[0031] Specifically, in this embodiment, when treating the waste liquid produced by aspartame, the waste liquid is first injected into the flocculation box 2, and then the flocculant is added. Then, the motor 311 is started by an external power supply. After the motor 311 is started, the stirring rod 313 is driven to rotate through the stirring shaft 314, thereby stirring the waste liquid and the flocculant to accelerate the flocculation speed. When the flocculation is completed and discharged, the waste liquid is sprayed on the surface of the filter plate 333 through the conveying pipe 8. At this time, the filter screen inside the filter plate 333 will separate the flocculants, and at this time, the rotating stirring shaft 314 will drive the first The second belt pulley 334 rotates, and the second belt pulley 334 drives the second bevel gear 3313 to rotate by cooperating with the second transmission wheel 339. The second bevel gear 3313 drives the irregular rotating roller 3310 to rotate through the fixed shaft 3312. At this time, the rotating irregular rotating roller 3310 drives the filter plate 333 to vibrate up and down through the irregular blocks on its surface, so that the flocculants vibrate on the surface of the filter screen inside the filter plate 333, thereby preventing the flocculants from being stuck on the surface of the filter screen inside the filter plate 333 and being unable to be cleaned when the brush holder 337 is cleaning.

[0032] When the filter plate 333 is vibrating, the connecting shaft 32 will drive the first transmission wheel 338 to rotate through the first pulley 331, and the first transmission wheel 338 will drive the screw rod 335 to rotate when rotating. The rotating screw rod 335 will drive the connecting block 3315 on one side of the wire sleeve 336 to move. When the connecting block 3315 moves, it will also drive the brush holder 337 to move to one side. Since the connection between the brush holder 337 and the connecting block 3315 is hinged, the brush holder 337 can self-adjust the angle between the brush holder 337 and the connecting block 3315 as the filter plate 333 vibrates, so that the vibration of the filter plate 333 does not affect the cleaning of its surface, thereby cleaning the flocculants to both sides of the filter plate 333 to complete the cleaning work, making it more convenient to clean the flocculants.

[0033] The filtered waste water will flow into the interior of the collection box 9, and then the waste liquid will be pumped into the interior of the evaporation box 4 by a water pump for evaporation. During evaporation, the external power supply starts the heater 10. After the heater 10 is started, it will heat the waste liquid in the evaporation box 4 to evaporate it, so that the salt and other impurities in the waste liquid will crystallize at the bottom of the evaporation box 4 to prevent the salt in the waste liquid from corroding the filtering device when the waste liquid is filtered later. The generated steam will flow in the heat exchange tube 342 through the air guide pipe 11, thereby conducting heat into the interior of the flocculation box 2 for the next round of treatment. The treated waste liquid is heated to make it mix more quickly with the flocculant. When the steam passes through the interior of the cooling water tank 341, the cooling water tank 341 is connected to an external cold water component to allow the cooling water to circulate inside the cooling water tank 341, thereby exchanging the residual heat of the steam inside the heat exchange tube 342, so that the steam becomes liquid and flows into the filter box 5. Then, the waste liquid is filtered again through the use of sand 7 and activated carbon 6 to reduce the toxic substances and impurities in the waste liquid, and then the filtered waste liquid is discharged, finally completing the treatment and recovery of the aspartame production waste liquid.

Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
