[0024] For further information, see Figure 1 and Figure 2 In this embodiment, a water inlet pipe 8 is installed at the bottom end of the grid well 3, and the water inlet pipe 8 extends to the inside of the grid well 3. A grid channel 9 is installed at the bottom end of the inner side of the grid well 3. The grid well 3 and the water inlet pipe 8 and the grid channel 9 are designed as an integrated structure. By connecting the sewage inlet pipe 8, the sewage can flow into the inside of the grid well 3. The grid channel 9 is used to control the flow rate. The main function of the grid well 3 is to intercept and remove larger suspended matter and floating matter in the sewage to protect the water pump and subsequent treatment units from being blocked or damaged, and the sludge is transported to the outside of the grid well 3 through the mechanical grid 4.
[0025] Among them, see Figure 2 In the present embodiment, a square groove 10 is provided at the bottom of the inner side of the grille well 3 and on the side away from the water inlet pipe 8. The grille well 3 is interconnected with the interior of the regulating tank body 2 through the square groove 10. A guide fold plate 1001 is installed inside the square groove 10. The filtered water will pass through the square groove 10 and flow into the interior of the regulating tank body 2. At the same time, the design of the guide fold plate 1001 can effectively prevent the sewage from being directly brought out of the regulating tank body 2 by the lifting pump 13 without being homogenized.
[0026] Furthermore, please see Figure 1 , Figure 2 and Figure 3 In the present embodiment, a limiting plate 11 is installed between the regulating tank body 2, the grille well 3 and the connecting frame 5, and the aeration flower tube 7 extends to the interior of the regulating tank body 2. The design of the limiting plate 11 can effectively prevent the grille well 3 and the connecting frame 5 from being misaligned with the regulating tank body 2 during installation, resulting in a gap between the three and inability to work normally. When sludge scaling appears on the inner wall of the regulating tank body 2, compressed air is regularly used through the aeration flower tube 7 to destroy and loosen the sludge.
[0027] For further information, see Figure 3 In this embodiment, a lift pump foundation 12 is installed at the bottom end of the inner side of the regulating tank body 2, a lift pump 13 is installed outside the lift pump foundation 12, an extension pipe 14 is installed inside the lift pump 13, a fixing seat 15 is installed outside the extension pipe 14, the extension pipe 14 is connected to the lift pump foundation 12 through the fixing seat 15, a lift pump outlet pipe 16 is installed at the top of the extension pipe 14, and the lift pump outlet pipe 16 extends to the outside of the connecting frame 5, and a support 17 is symmetrically installed on the outside of the regulating tank body 2, and the purified water flows to the inside of the regulating tank body 2 by gravity. By starting the lifting pump 13, the water pressure is increased, the flow rate of the liquid is accelerated, and the liquid is drawn from a low place, so that the liquid flows from the inside of the extension pipe 14 to the lifting pump outlet pipe 16, and finally discharged from the outside of the device. Through the design of the fixed seat 15 and the lifting pump foundation 12, the lifting pump 13 and the extension pipe 14 can operate stably, which greatly extends the working life. At the same time, the support 17 outside the regulating pool tank body 2 is equipped with a fixing ear for connecting the embedded parts of the raft foundation 1, so that the entire device and the raft foundation 1 form a whole, which can effectively resist the buoyancy of groundwater.
[0028] For further information, see Figure 1 , Figure 2 and Figure 3In the present embodiment, the regulating tank body 2, the aeration flower tube 7, the guide folded plate 1001, the limit plate 11, the lifting pump foundation 12 and the support 17 are all of an integrated structural design, and the regulating tank body 2, the grille well 3, the connecting frame 5, the water inlet pipe 8, the grille channel 9, the guide folded plate 1001, the limit plate 11, the lifting pump foundation 12 and the support 17 are all made of glass fiber reinforced plastics, and the grille well 3 and the water inlet pipe 8 and the grille channel 9 are of an integrated structural design, and the regulating tank body 2, the aeration flower tube 7, the guide folded plate 1001, the limit plate 11, the lifting pump foundation 12 and the support 17 are of an integrated structural design, and the above components are made of glass fiber reinforced plastics, which avoids the unfavorable factors such as long construction period, high cost and great difficulty of cast-in-place steel concrete construction.

[0029] In this embodiment, the implementation scenario is specifically as follows: by connecting the sewage inlet pipe 8, the sewage is allowed to flow into the interior of the screen well 3, and the screen channel 9 is used to control the flow rate. The main function of the screen well 3 is to intercept and remove larger suspended matter and floating matter in the sewage to protect the water pump and subsequent treatment units from being blocked or damaged. The sludge is transported to the outside of the screen well 3 through the mechanical screen 4, and the filtered water will pass through the square groove 10 and flow into the interior of the regulating tank body 2. At the same time, the design of the guide folding plate 1001 can effectively prevent the sewage from being directly taken out of the regulating tank body 2 by the lifting pump 13 without being homogenized. By starting the lifting pump 13, the water pressure is increased, the liquid flow rate is accelerated, and the liquid is extracted from a low place, so that the liquid flows from the inside of the extension pipe 14 to the lifting pump outlet pipe 16, and finally discharged outside the device.
