Referring to fig. 1 and 2, a rural small-size sewage treatment device that uses, including jar body 1, the horizontal cross-section of jar body 1 main part is the rectangle, and jar body 1 is inside to be provided with multilayer filter screen 2, and each layer filter screen 2 from top to bottom aperture reduces in proper order. Each layer of filter screen 2 is at a certain angle with the horizontal plane, and the lowest end of each layer of filter screen 2 is flush with the uppermost end of the adjacent filter screen 2 in the vertical direction. Further, except for the lowest layer of filter screen 2, a guide plate 8 is arranged below the filter screen 2 close to each layer and used for guiding water penetrating through the filter screen 2 to the upper end of the lower layer of filter screen 2. Through-hole 3 has been seted up to the 1 lateral wall of jar body of every layer of filter screen 2 lower extreme department, and the 3 outsides of through-hole are provided with guiding gutter 4, and all guiding gutters 4 finally flow back to female pipe 5 of blowdown. Furthermore, the upper part of the diversion trench 4 is of an open structure, so that the impurities deposited in the diversion trench 4 can be conveniently cleaned. A water inlet 6 is arranged on the tank body 1 right above the upper end of the uppermost layer filter screen 2, and a water outlet 7 is arranged at the bottom of the tank body 1. Further, the bottom of the tank body 1 is of a conical structure with a low middle part and high periphery, so that water flow can be conveniently collected and discharged out of the tank body 1. A plurality of landing legs 9 are fixed at the bottom of the tank body 1, so that the tank body 1 can be stably placed on the ground.

The utility model discloses a use method as follows:

the sewage to be treated is discharged into the tank body 1 from the water inlet 6 at the upper end of the tank body 1, the sewage is sequentially filtered by the multilayer filter screens 2, and the aperture of each filter screen 2 is sequentially reduced. Sewage is when every layer of filter screen 2, and solid impurity is kept apart in the top by filter screen 2, because filter screen 2 is the slope, partial rivers can be along filter screen 2 a direct current to filter screen 2 lower extreme, take the solid impurity on the filter screen 2 to the filter screen 2 lower extreme simultaneously to through the 3 discharge tank bodies of through-hole 1, through the female pipe 5 of blowdown of guiding gutter 4 inward-remittance. The clear water after the filtration of multilayer filter screen 2 then discharges from the delivery port 7 of jar body 1 bottom. Further, sewage discharged by the main sewage discharge pipe 5 can be statically settled and then is introduced into the water inlet 6 again, so that the aim of recycling is fulfilled. Further, the inclination angle of each layer of filter screen 2 is adjusted, so that the sewage discharge effect and the proportion of sewage discharge in the total water inflow can be adjusted.

In the use, increase the inflow suddenly at regular intervals or use the air bubble to disturb filter screen 2, can reach the purpose of cleaing away adnexed stubborn impurity on the filter screen 2. The cleaning liquid can be introduced regularly to wash the filter screen 2 thoroughly, and the water outlet hole is isolated from the clean water pipeline.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and should not be taken as limiting the invention, and all modifications, equivalents, improvements and the like that are made within the spirit and principles of the present invention should be included in the scope of the present invention.
