[0024] See also Figure 1-3 , the utility model provides a technical solution:

[0025] An industrial wastewater treatment pool includes a treatment pool body 1, an inner cavity is provided inside the treatment pool body 1, a first baffle 18 and a second baffle 20 are respectively provided at the bottom of the inner cavity along the longitudinal direction, the tops of the first baffle 18 and the second baffle 20 are connected to the top of the inner cavity of the treatment pool body 1, the first baffle 18 and the second baffle 20 divide the inner cavity of the treatment pool body 1 into a first inner cavity 21, a second inner cavity 22, and a third inner cavity 23, a water inlet 4 is provided at the center of the top of the first inner cavity 21, a filter plate 14 is obliquely provided at the top of the first inner cavity 21, and a sewage outlet is provided on one side of the first inner cavity 21 and at the bottom of the filter plate 14 6. The sewage outlet 6 is internally snap-fitted with a blocking block 5. Rotating rods 16 are arranged at both ends of the first inner cavity 21 and below the bottom of the filter plate 14. A stirring blade 17 is arranged on the surface of the rotating rod 16. A rotating shaft 15 is arranged at one end of the rotating rod 16. The rotating shaft 15 is located inside the treatment tank body 1. The other end of the rotating shaft 15 is connected to the output end of the driving motor 7. The back of the driving motor 7 is fixedly connected to one side of the treatment tank body 1. A plurality of ultraviolet disinfection lamps 19 are arranged at the bottom of the second inner cavity 22. Activated carbon 24 is arranged inside the third inner cavity 23. A water outlet is arranged at the bottom of the other side of the treatment tank body 1.

[0026] Furthermore, a second connecting water pipe 12 is provided at the bottom of the front side of the treatment pool body 1 , one end of the second connecting water pipe 12 is connected to the first inner cavity 21 , and the other end of the second connecting water pipe 12 is connected to the second inner cavity 22 .

[0027] Furthermore, a second water pump 13 is disposed on the surface of the second connecting water pipe 12 .

[0028] Furthermore, a first connecting water pipe 2 is provided at the bottom of the back side of the treatment pool body 1 , one end of the first connecting water pipe 2 is connected to the second inner cavity 22 , and the other end of the first connecting water pipe 2 is connected to the third inner cavity 23 .

[0029] Furthermore, a first water pump 3 is disposed on the surface of the first connecting water pipe 2 .

[0030] Furthermore, a drug storage port 8 is provided on the upper back side of the treatment pool body 1 , a drug inlet pipe 9 is provided at the bottom of the drug storage port 8 , and the other end of the drug inlet pipe 9 is communicated with the first inner cavity 21 .

[0031] Furthermore, a water valve 10 and a one-way valve 11 are respectively provided on the surface of the medicine inlet pipe 9 , and the one-way valve 11 is located in front of the water valve 10 .

[0032] Specifically, when in use, the interior of the medicine storage port 8 is provided with previously prepared medicine. When it is necessary to add medicine to the first inner cavity 21, it is only necessary to open the water valve 10. The setting of the one-way valve 11 ensures that the medicine enters the first inner cavity 21 from the medicine storage port 8, and prevents the liquid in the first inner cavity 21 from entering the medicine storage port 8.

[0033] Furthermore, a through groove is provided on the back of the treatment pool body 1, and the two ends of the through groove are at the same horizontal plane as the two ends of the first inner cavity 21. A card block (not shown in the figure) is snap-connected to the through groove. Specifically, during the flocculation and sedimentation process, a certain amount of flocs will be produced. When the water is transported to the second inner cavity 22 through the first connecting water pipe 2, the flocs will gather at the bottom of the first inner cavity 21. After all the water in the first inner cavity 21 enters the second inner cavity 22, the card block is pulled out, thereby removing the flocs from the through groove, which will not affect the treatment effect after adding industrial wastewater from the water inlet 4 again.

[0034] Furthermore, filter screens (not shown) are provided at the connections between the first connecting water pipe 2 and the second connecting water pipe 12 and the treatment tank body 1. The filter screens here will play a role of secondary filtering to prevent impurities from entering the next inner cavity from the first connecting pipe or the second connecting pipe, thereby improving the wastewater treatment efficiency.

[0035] Working principle: When in use, the staff pours the industrial wastewater from the water inlet 4, so that the industrial wastewater enters the first inner cavity 21. After the industrial wastewater passes through the preliminary filtration of the filter plate 14, it will enter the bottom of the filter plate 14. Then, the block 5 is removed. Because the filter plate 14 is inclined, the insoluble impurities in the industrial wastewater will flow out from the sewage outlet 6. Then, the block 5 is reinserted into the sewage outlet 6. Then, the water valve 10 is opened, and the reagent is poured into the first inner cavity 21 and located at the filter plate 14. Below the bottom, after waiting for a period of time, the second water pump 13 is turned on, so that the water enters the second inner cavity 22 from the first inner cavity 21, and the water is disinfected by the ultraviolet disinfection lamp 19 in the second inner cavity 22. After waiting for a period of time, the first water pump 3 is started, so that the water enters the third inner cavity 23 from the second inner cavity 22. The third inner cavity 23 is filled with activated carbon 24, which will purify the water again. In addition, the water purified by the activated carbon 24 will be discharged from the water outlet, thereby realizing the treatment of working wastewater.

[0036] It should be noted that after the industrial wastewater is filtered through the filter plate 14 and the chemicals are added, in order to improve the uniform mixing of the chemicals and water, the drive motor 7 can be started. The rotation of the drive motor 7 will cause the rotating shaft 15 to rotate, and the rotation of the rotating shaft 15 will cause the rotating rod 16 to rotate. The rotation of the rotating rod 16 will cause the stirring blade 17 to rotate, thereby stirring the water and the chemicals, so that the water and the chemicals are mixed evenly, which is beneficial to improving the flocculation efficiency.

[0037] Furthermore, after stirring for a period of time, the driving motor 7 is turned off, and the second water pump 13 is turned on after the driving motor 7 has been turned off for a period of time.

[0038] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
