[0039] The buffer tank 28 is also connected to the air flotation machine 13 via the tenth pipeline 25 equipped with the seventh pump 26. The liquid discharged from the still 1 enters the buffer tank 28 for natural cooling, and then enters the air flotation machine 13 for treatment.

[0040] The air flotation machine 13 is connected to the regulating tank 16 through the sixth pipeline 14 equipped with the third pump 15. The organic and inorganic contents of the water treated by the air flotation machine 13 are greatly reduced, which can reduce the burden of the subsequent treatment process and speed up the treatment.

[0046] The bottom of the heating tank 61 is fixedly connected to the first end of the transition pipe 63, and the second end of the transition pipe 63 is fixedly connected to the top of the first water distribution tank 65. The first water distribution tank 65 can be as shown in the attached Figure 3 and attached Figure 4 It is shown as a part of the bottom wall of the still 1, and can also be welded and fixed to the top of the bottom wall of the still 1.

[0047] The structure of the first water distribution tank 65 is shown in the attached Figure 4 As shown, the interior is hollow, with a first water confluence port 72 connected to the transition pipe 63 at the top and a plurality of first water distribution holes at the bottom, each of which is fixedly connected to the top of a corresponding branch pipe 67. The plurality of branch pipes 67 are distributed in a circular array around the axis of the still 1.

[0048] All the branch pipes 67 are sleeved in the drain pipe 66, the bottom of the drain pipe 66 is closed, and a second water distribution box 68 is fixedly installed on the bottom wall of the drain pipe 66. The second water distribution box 68 is also hollow, and a plurality of second water distribution holes are provided on the top, and each second water distribution hole is fixedly connected to the corresponding branch pipe 67.

5. The wastewater treatment device of propiconazole according to claim 4, characterized in that: A first stirring shaft driven by a first motor (55) is also installed in the flocculation chamber, and a plurality of first fan blades are installed on the first stirring shaft.

6. The wastewater treatment device of propiconazole according to claim 4, characterized in that: A weir plate (38) matching the clean water outlet (39) is installed in the clean water chamber (42).

7. The wastewater treatment device of propiconazole according to claim 4, characterized in that: A plurality of groups of flotation tubes are installed in the flotation chamber (48), each group of the flotation tubes comprising two vertical second air tubes (34), the tops of the second air tubes (34) being connected to the first air tube (33), the first air tube (33) being connected to the air dissolving tank (53) via a thirteenth pipeline (54), and the air dissolving tank (53) being further connected to the clean water outlet (39) via a pipeline.

8. A method for treating wastewater of a wastewater treatment device of propiconazole according to claim 4, characterized in that: The following steps are involved: Step 1: The sewage enters the second water distribution tank (68) through the twelfth pipeline (31), then passes through the branch pipe (67), and finally enters the heating tank (61) for heating. The evaporated low-boiling point components are condensed through the condenser (3) and enter the liquid storage tank (7). The remaining sewage enters the buffer tank (28) through the drain pipe (66); Step 2: The sewage in the buffer tank (28) enters the flocculation chamber of the air flotation machine (13) and is mixed with the flocculant and sodium carbonate solution that simultaneously enter the flocculation chamber; Step 3: Turn on the power supply (51) to generate current in the flocculation chamber; Step 4: The sewage in the flocculation chamber is discharged into the regulating tank (16) through the flotation chamber (48), the slag discharge chamber (44), and the clean water chamber (42) of the flotation machine (13) in sequence; Step 5: The pH of the sewage in the regulating tank (16) is adjusted to neutral; Step 6: The sewage adjusted to neutrality enters the anaerobic tank (19) and the aerobic tank (22) for treatment in sequence; Step 7: The sewage treated in the aerobic tank (22) enters the sedimentation tank (27) to remove the sediment and then is discharged.
