[0045] Working principle and use process of the present invention: After the present invention is installed, when in use, the farmland wastewater is first introduced into the first treatment box 1 through the water inlet pipe 5, the wastewater enters the cylinder 9, and is filtered by the second filter screen 11 and the first filter screen 10 in turn, effectively removing large particles of impurities in the water, and the filtered water flows into the second treatment box 2 through the first conduit 12 for buffering and reducing the flow rate, which is helpful for subsequent treatment;

[0046] In the second treatment box 2, the water is further filtered by the first filter cover 14 to remove smaller particles of impurities. Subsequently, the water flows into the third treatment box 3 through the second conduit 13. In the third treatment box 3, a biological precipitant is added to the water through the feeding pipe 18, and at the same time, the motor 15 is started to drive the rotating shaft 16 and the stirring rod 17 to rotate, so that the biological precipitant is evenly dispersed in the water to promote the precipitation of impurities.

[0047] The settled water flows into the fourth treatment box 4 through the third conduit 19, and is filtered again by the second filter cover 20 and the filter plate 21 to ensure that the water quality meets the discharge standard. Finally, the treated water is discharged through the outlet pipe 6 and can be used for farmland irrigation or other purposes.

[0048] The farmland drainage structure of the present invention not only realizes the effective treatment of farmland wastewater, but also improves the utilization rate of water resources and reduces environmental pollution. At the same time, it has a compact structure, is easy to operate and maintain, and is suitable for various farmland drainage scenarios.

[0049] The farmland drainage structure of the present invention has the following advantages when in operation: first, through the design of multi-stage treatment boxes, the wastewater is gradually treated, and each stage of the treatment box undertakes different treatment tasks, thereby ensuring the high efficiency and stability of the treatment effect. The first treatment box is mainly responsible for preliminary filtration to remove large particle impurities; the second treatment box plays a role of buffering and further filtration; the third treatment box effectively removes suspended matter and dissolved organic matter in the water through chemical sedimentation; the fourth treatment box performs final filtration and purification to ensure that the water quality meets the standards.

[0050] Secondly, the filtering component of the present invention improves the filtering effect through the design of multi-stage filter screen. At the same time, the design of the cylinder body inserted in the slot is convenient for lifting and cleaning; the chemical sedimentation component is stirred by a motor-driven stirring rod to make the biological sedimentation agent evenly dispersed in the water, thereby improving the sedimentation efficiency.
