[0022] In this embodiment, please refer to Figure 1-Figure 4 , the staff connected the water pipe with wastewater to the water inlet pipe 7 through bolts, a filter tube 13 of the same shape is arranged inside the spiral tube 5, and the pore size of the filter tube 13 is smaller than that of the spiral tube 5, there is a gap between the two, and the spiral tube 5 and the filter tube 13 are connected to the water pump 6 through bolts, and a plurality of filter holes 14 are opened on the filter tube 13. Because the filter tube 13 has an exaggerated bending angle, when the water pump 6 draws the wastewater into the filter tube 13, the wastewater with a high flow rate collides with the inner wall of the filter tube 13, and a part of the wastewater collides with the inner wall of the filter tube 13. The wastewater enters the gap between the spiral tube 5 and the filter tube 13 through the filter hole 14 on the filter tube 13. The filter tube 13 can perform preliminary filtration on the wastewater, and then the wastewater is discharged from one end of the spiral tube 5, and finally enters the wastewater storage tank 1 after secondary filtration through the filter screen 4. Since the filter tube 13 is relatively long, it can perform long-term filtration work without being quickly blocked by impurities in the wastewater. The filter hole 14 opened on it prolongs the time for the staff to replace the filter screen 4 and the filter tube 13 each time;

[0023] In this embodiment, please refer to Figure 1-Figure 2 A support column 11 is provided at the lower end of the wastewater storage tank 1, and the support column 11 is welded to the wastewater storage tank 1.

The aperture of the filter tube 13 is smaller than that of the spiral tube 5. There is a gap between the two. The spiral tube 5 and the filter tube 13 are connected to the water pump 6 through bolts. A plurality of filter holes 14 are provided on the filter tube 13. Because the filter tube 13 has an exaggerated bending angle, when the water pump 6 draws wastewater into the filter tube 13, the wastewater with a high flow rate collides with the inner wall of the filter tube 13. Part of the waste water enters the gap between the spiral tube 5 and the filter tube 13 through the filter hole 14 on the filter tube 13. The filter tube 13 can perform preliminary filtration on the waste water, and then the waste water is discharged from one end of the spiral tube 5, and finally enters the waste water storage tank 1 after secondary filtration through the filter screen 4. Since the filter tube 13 is relatively long as a whole, it can perform long-term filtration work without the filter hole 14 opened thereon being quickly blocked by impurities in the waste water, thereby extending the time for the staff to replace the filter screen 4 and the filter tube 13 each time.
