[0022] The following is combined Figure 1-10The wastewater treatment system involved in this utility model will be further explained and described.

[0023] A wastewater treatment system includes a first water pump 2, a high-pressure filter box 3, a second water pump 4, a physical filter box 5, a third water pump 6, and a mixing tank 7. The first water pump 2 is connected to a cleaning machine 1 and the high-pressure filter box 3 via pipelines at both ends, and is used to pump wastewater from the cleaning machine 1 into the high-pressure filter box 3. The second water pump 4 is connected to the high-pressure filter box 3 and the physical filter box 5 via pipelines at both ends, and is used to pump the wastewater filtered by the high-pressure filter box 3 into the physical filter box 5. The third water pump 6 is connected to the physical filter box 5 and the mixing tank 7 via pipelines at both ends, and is used to pump the wastewater filtered by the physical filter box 5 into the mixing tank 7. The mixing tank 7 is used to mix the wastewater with chemicals. The high-pressure filter box 3 includes a first housing 31, a fine screen 32, and a high-pressure air inlet assembly 33. The fine screen 32 is fixedly connected to the inner wall of the first housing 31. The high-pressure air inlet assembly 33 is connected to the output pipe of the first water pump 2 and is used to spray the wastewater at high pressure onto the fine screen 32.

[0024] In this embodiment, there are three-stage treatment processes: high-pressure treatment, physical treatment, and stirring treatment. The wastewater first passes through the high-pressure filter box 3. Under the action of the first water pump 2 and the high-pressure air inlet component 33, the wastewater is impacted at a higher speed by the fine screen 32. The fine screen 32 blocks silt and other particulate impurities. Then, it is pumped into the physical filter box 5 by the second water pump 4 and into the stirring box 7 by the third water pump 6. Through physical filtration again and mixing with the reagent, a better wastewater treatment effect is achieved, thereby solving the technical problem that the existing wastewater treatment methods cannot meet the requirements.

[0025] In one embodiment of a wastewater treatment system, a fine screen 32 is inclined, and the high end of the fine screen 32 is located on the side away from the connection between the first water pump 2 and the first housing 31.

[0026] In this embodiment, with the action of the high-pressure air inlet component 33 and the first water pump 2, the tailwater entering the first housing 31 will directly impact the high part of the fine screen 32, while mud, sand and other particulate impurities will slide down to the low part of the fine screen 32 under the continuous impact of the tailwater, thus accumulating at the low part without affecting the continued filtration at the high part.

[0027] Preferably, the first housing 31 also has a rotating door 34, which can be opened and closed. The position of the rotating door 34 corresponds to the lower part of the fine screen 32, thereby facilitating the cleaning of impurities at the lower part of the fine screen 32 by the staff.

[0028] In one embodiment of a wastewater treatment system, the bottom of the first tank 31 is inclined.

[0029] In this embodiment, by setting the bottom of the first tank 31 to be inclined, the tailwater can easily flow to a lower position, and then the tailwater can be discharged through the opening at the bottom of the first tank 31, so that the tailwater can flow out completely from the first tank 31 and avoid accumulation.

[0030] In one embodiment of a wastewater treatment system, the physical filter box 5 includes a second box body 51, a uniform water outlet pipe 52, and a biochemical cotton 53. The uniform water outlet pipe 52 is fixedly connected to the output pipe of the second water pump 4 and is suspended inside the second box body 51. The biochemical cotton 53 is fixedly connected to the inner wall of the second box body 51 and is located below the uniform water outlet pipe 52. The uniform water outlet pipe 52 includes multiple water outlet pipes 521 and a connecting pipe 522. Each water outlet pipe 521 is arranged in parallel, and the connecting pipe 522 passes through each water outlet pipe 521 and is connected to the output pipe of the second water pump 4. Each water outlet pipe 521 has a water outlet hole on the side facing the biochemical cotton 53.

[0031] In this embodiment, the multiple water outlet pipes 521 in the uniform water outlet pipe 52 are all arranged horizontally. This arrangement makes the overall water outlet holes on the water outlet air pipe form a matrix arrangement and are located at the same height. The second water pump 4 pumps the tailwater from the first tank 31 into the connecting pipe 522, and then guides it one by one into the water outlet pipes 521 through the connecting pipe 522. Finally, it drips onto the biochemical cotton 53 through the water outlet holes, and the biochemical cotton 53 achieves the effect of biochemical filtration.

[0032] Preferably, the connecting pipe 522 extends perpendicularly to each water outlet pipe 521. The biochemical cotton 53 has holes.

[0033] In one embodiment of a wastewater treatment system, the physical filter box 5 further includes a fixed filter screen 54, which is fixedly connected to the inner wall of the second box 51 and located below the biochemical cotton 53.

[0034] In this embodiment, by setting a fixed filter screen 54 below the biochemical cotton 53, the filtration effect can be further enhanced, thereby strengthening the overall physical filtration effect of the second box 51.

[0035] In one embodiment of a wastewater treatment system, the bottom of the second tank 51 is inclined.

[0036] In this embodiment, similar to the inclined bottom of the first tank 31, by setting the bottom of the second tank 51 to be inclined, the tailwater can easily flow to a lower position, and then the tailwater can be discharged through the opening at the bottom of the second tank 51, so that the tailwater can flow out completely from the second tank 51 and avoid accumulation.

[0037] In one embodiment of a wastewater treatment system, the mixing tank 7 includes a third tank body 71 and a mixing assembly 72. The mixing assembly 72 includes a motor 721 and a mixing blade 722. The output end of the motor 721 is fixedly connected to the mixing blade 722. The motor 721 is fixedly connected to the third tank body 71 through a connecting rod. The mixing blade 722 extends into the third tank body 71.

[0038] In this embodiment, a motor 721 and a stirring paddle 722 are provided. The motor 721 drives the stirring paddle 722 to rotate and stir the tailwater in the third tank 71. By stirring the mixture of tailwater and agent, the tailwater and agent can be fully mixed, thereby achieving a better tailwater treatment effect. In this embodiment, the motor 721 is fixed to the third tank 71 by a connecting rod and the motor 721 is suspended by the connecting rod.

[0039] Based on the preceding embodiments, it can be understood that the first water pump 2, the second water pump 4, and the third water pump 6 all pump the tailwater from the bottom of the front tank to the top of the rear tank. Furthermore, the second tank 51 and the third tank 71 can be designed without top covers for ease of installation of the corresponding structures.

[0040] It should be noted that, in this embodiment, an outlet can be opened at the bottom of the third tank 71, and a solenoid valve can be installed on the outlet pipe connected to the outlet. The discharge of tailwater in the third tank 71 can be achieved by controlling the opening and closing of the solenoid valve.

[0041] In one embodiment of a wastewater treatment system, a third housing 71 is provided with a first partition 81 and a second partition 82. The first partition 81 is fixedly connected to the bottom of the third housing 71 and to the side wall of the third housing 71, thereby dividing the internal space of the third housing 71 into a mixing chamber 711 and an outflow chamber 712. An agitator 722 extends into the mixing chamber 711, and an outflow hole is provided on the bottom of the third housing 71 corresponding to the outflow chamber 712. The second partition 82 is arranged parallel to the first partition 81 and is located on the side of the first partition 81 opposite to the agitator 722. The second partition 82 is fixedly connected to the inner wall of the third housing 71 and is spaced apart from the bottom of the third housing 71. The top of the second partition 82 is higher than the first partition 81.

[0042] In this embodiment, the mixing chamber 711 and the outflow chamber 712 are separated by a first partition 81. Correspondingly, the mixing chamber 711 is used for mixing by the mixing paddle 722. Then, by setting a second partition 82, the tailwater can rise along the gap between the first partition 81 and the second partition 82, and finally cross the top of the first partition 81 and enter the outflow chamber 712.

[0043] It is understandable that an overflow channel is formed between the first partition 81 and the second partition 82, and the height of the first partition 81 must be lower than the height of the side wall of the third box 71.

[0044] In one embodiment of a wastewater treatment system, the second partition 82 has a protruding unit 83, which is a plate-shaped structure. The protruding unit 83 is located at the top of the second partition 82 and extends toward the first partition 81, and is higher than the first partition 81.

[0045] In this embodiment, specifically, the second partition 82 is L-shaped, and the protruding unit 83 is a short plate. By setting the protruding unit 83, the tailwater can be blocked, preventing the tailwater from spraying directly out from the gap between the first partition 81 and the second partition 82, thereby facilitating the tailwater to enter the outflow chamber 712.

[0046] In one embodiment of a wastewater treatment system, the surface of the protruding unit 83 facing the first partition 81 is parallel to the upper end surface of the first partition 81.

[0047] In this embodiment, this configuration can further improve the effect of guiding the tailwater into the outflow chamber 712.

[0048] Preferably, the transition between the protruding unit 83 and the body of the second partition 82 is an arc transition, which can avoid the formation of dead angles. Furthermore, the thickness of the first partition 81 can be set to be larger, and the extension length of the protruding unit 83 can be matched with the thickness of the first partition 81. In this way, a longer channel is formed between the first partition 81 and the protruding unit 83. The extension of this channel further facilitates the tail to enter the outflow chamber 712 horizontally and gently.

[0049] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0050] The above embodiments only illustrate several implementation methods of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
