The feeding tank 12 has a cylindrical structure and includes multiple first through holes 1 at one end of the top of the feeding tank 12. 21, a water inlet pipe 122 located at the other end of the top of the feeding tank 12, a first flow valve 123 located in the middle of the water inlet pipe 122, and a control panel 124 located on the outside of the reaction chamber 10; the stirring component 13 includes a motor 131 located at the top of the feeding tank 12, and a stirring rod 132 located inside the feeding tank 12 and connected to the motor 131; the feeding component 14 includes an additive tank 141 located at the top of the feeding tank 12, a guide pipe 142 connecting the additive tank 141 and one end of the feeding tank 12, and a second flow valve 143 located at the outlet end of the guide pipe 142.

[0026] It should be noted that the flow of the second flow valve 143 is proportional to the flow of the first flow valve 123, and the proportional relationship can be adjusted using the control panel 124; the stirring component 13 can stir the sewage and flocculants added to the feeding tank 12 uniformly, and can prevent the sewage from flocculating in the feeding tank 12, causing the bottom to accumulate or the first through hole 121 to be blocked;

[0027] Further, adjust the control panel 124 to adjust the proportional relationship of the second flow valve 143 and the first flow valve 123, open the first flow valve 123, and pour the sewage from the water inlet pipe 122 into the feeding tank 12;

[0028] Further, the second flow valve 143 conducts the material pipe 142 according to the proportional relationship of the first flow valve 123, and the flocculants in the additive tank 141 are proportionally introduced into the feeding tank 12;

[0029] Further, the motor 131 is started to drive the stirring rod 132 to rotate and stir the sewage and flocculants in the feeding tank 12, so that they are mixed uniformly. The mixed sewage and flocculants continuously added from the first through hole 121 leak into the reaction box 10 for primary reaction, so that part of the sewage impurities are precipitated at the bottom of the reaction box 10.

[0030] Please refer to Figs. 3, 4 and 5 for details. Figure 1 、 2 The inclined pipe group 15 includes a plurality of regular hexagonal inclined pipes 151 arranged in the middle of the sedimentation tank 11, a plurality of second through holes 152 connecting the reaction box 10 in the middle of the sedimentation tank 11, and an observation window 153 on one side of the sedimentation tank 11.

The vertical height between the regular hexagonal inclined pipe 151 and the hopper 16 is 1.0 m, and this area is the settling area; the filter screen 173 is relatively high, part of the area is higher than the top of the sedimentation tank 11, which is convenient for replacement, the permeability of the filter screen 173 is relatively high, which is responsible for filtering part of the powdery impurities, the removable installation structure can frequently replace filter screens with different pore sizes to adapt to different requirements of sewage treatment, and the sedimentation of the sewage can be observed through the observation window 153.

[0032] Further, when the liquid level in the reaction tank 10 rises to a certain height, the mixed liquid flows into the sedimentation tank 11 from the plurality of second through holes 152;

[0033] Further, as the liquid level in the sedimentation tank 11 gradually rises, the mixed liquid is efficiently precipitated in each obliquely arranged regular hexagonal inclined pipe 151, and the precipitate is concentrated in the sedimentation zone and below, and falls into the plurality of hoppers 16 at the bottom under the action of gravity;

[0034] Further, the pump 163 is started to drive the mud discharge pipe 161 through the discharge pipe 162 to discharge the mud and sand at the bottom of the hopper 16 and the reaction tank 10 from the system;

[0035] Further, as the liquid level in the sedimentation tank 11 gradually rises, the clear water separated from the precipitate penetrates the filter screen 173 into the water filtering tank 17, and the clear water is discharged through the drain pipe 174;

[0036] Further, if it is necessary to adjust the filtering degree of the clear water, the filter screen 173 can be pulled out from the first and second insertion slots 171 and 172, and a new filter screen is inserted into the first and second insertion slots 171 and 172.
