DETAILED DESCRIPTION

[0023] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0024] Example: Figure 1 and Figure 2As shown, a sewage treatment device for improving filtering effect includes a base 1, and the four corners of the lower end of the base 1 are fixedly connected to support feet 4 for stability. The lower end of the support feet 4 is provided with a rubber pad for anti-skid and shock absorption. A sludge baffle 21 for discharging sludge is provided in the pretreatment box 2. The precipitated sludge is discharged to the sludge port 13 provided inside the base 1 by pulling the slide rail according to the degree of sludge collection. The upper end of the base 1 is provided with a pretreatment box 2 for initial sedimentation and filtration. A sewage inlet 8 for sewage inflow is provided on one side of the pretreatment box 2. A U-shaped filter screen 12 and a stirring rod 11 are installed inside the pretreatment box 2. The stirring rod 11 is connected to the driving shaft of a motor 29. The motor 29 drives the stirring rod 11 to stir the water flow to generate a vortex. Under the action of the vortex, solid particles will settle to the bottom, thereby achieving separation and filtration, and then the U-shaped filter screen 12 is used to effectively filter the suspended particles and solid impurities in the wastewater for the first layer of filtration. The water pump 3 is installed at the upper end of the pretreatment box 2. The control box 5 controls the operation of the water pump 3 and the motor 29. The water pump 3 is operated by the control box 5 to generate pressure to extract the first-treated sewage through the suction pipe 10 on one side of the water pump 3 and transport it to the outlet pipe 6. The sewage flows into the filter box 7 for secondary filtering through one end of the outlet pipe 6. The interior of the filter box 7 is provided with a first filter screen 15. The lower end of the first filter screen 15 is provided with a second filter screen 27 for re-filtration. The lower end of the second filter screen 27 is provided with a third filter screen 28 for adsorbing, decomposing and removing harmful substances. Then the sewage flows to the disinfection box 9. The disinfection box 9 is located below the filter box 7. One side of the disinfection box 9 is provided with a medicine port 19 for placing disinfectants. After disinfection and precipitation in the disinfection box 9, the sewage is discharged from the clean water outlet 20. The first filter screen 15 is a ceramic filter screen. The ceramic filter screen has excellent high temperature resistance and corrosion resistance, and can filter microorganisms, particles and other substances in the water. The second filter screen 27 is an ultrafiltration membrane filter screen. The ultrafiltration membrane filter screen introduces membrane separation technology and uses a special ultrafiltration membrane for filtering. This filter can filter out microorganisms, heavy metals and other substances in the water. The third filter 28 is a carbon filter, which is usually made of activated carbon. It has a very high adsorption capacity and can effectively remove chlorine, odor and organic pollutants in the water.

[0025] like Figure 1 and Figure 3As shown, the pretreatment box 2 has a first filter 15, a second filter 27 and a third filter 28 inside, and filter rails 14 for sliding and pushing are provided at both ends of the filter. A baffle 16 is connected to one side of the first filter 15, and a sealing gasket for waterproof sealing is provided at the connection between the baffle 16 and the filter. A filter layer handle 17 for pulling out is installed on one side of the baffle 16. The filter is pulled by the filter layer handle 17, so that the filter is convenient to replace and clean. The pretreatment box 2 is provided with a safety buckle 18 on the same side of the baffle 16. The safety buckle 18 is used to prevent the filter from sliding due to the working vibration of the sewage treatment device. When the filter needs to be pulled out, the safety buckle 18 only needs to be pushed to one side, and the filter can be pulled out by opening the safety buckle 18.

[0026] like Figure 1 and Figure 4 As shown, a trolley rail 26 is provided at the lower end of the base 1, and a groove corresponding to the protruding part of the upper end of the sludge transfer vehicle 24 is provided at the lower end of the trolley rail 26. A folding baffle 23 for preventing the sludge transfer vehicle 24 from being dislocated is provided on one side of the base 1. The folding baffle 23 is connected to the base 1 by a hinge, and the fixing buckle 25 is used to fix the sludge transfer vehicle 24 and the folding baffle 23. A trolley handle 22 for facilitating the movement of the sludge transfer vehicle 24 is installed on the front side of the sludge transfer vehicle 24, and a pulley is installed under the sludge transfer vehicle 24 to improve the processing efficiency.

[0027] Working principle: sewage flows into the pretreatment tank 2 through the sewage inlet 8, and the suspended solids are filtered through the U-shaped filter 12. The motor 29 drives the stirring rod 11 to increase the water flow and accelerate the sedimentation. The treated sewage is pressurized by the control box 5 to control the operation of the water pump 3 so that it is output from the suction pipe 10 and pumped into the outlet pipe 6 to flow into the filter box 7. The sewage will pass through the first filter 15, the second filter 27 and the third filter 28 to adsorb and decompose harmful substances. The treated sewage flows into the disinfection tank 9, and the disinfectant can be added through the medicine port, and finally discharged through the clean water outlet 20. After the sewage is treated, the precipitated sludge is discharged by pulling the sludge barrier plate 21, and falls from the sludge port 13 to the sludge transfer vehicle 24. The sludge transfer vehicle 24 can be pushed out by opening the fixing buckle 25 and the folding baffle 23. The filter can be replaced by opening the safety buckle 18, and the filter layer handle 17 and the baffle 16 are used to pull the first filter 15 to slide and pull out the filter to replace and clean the filter.
