Description

Technical Field

[0001] This utility model belongs to the field of farmland drainage purification technology, and in particular relates to a farmland drainage purification device. Background Technology

[0002] Farmland runoff primarily originates from flood irrigation and sudden heavy rainfall. Flood irrigation is the main irrigation method in my country's agriculture, with most of the irrigation water eventually becoming surface runoff and flowing into rivers. Heavy rainfall, on the other hand, carries nutrients, antibiotics, pesticides, and other pollutants from farmland into water bodies as runoff. This runoff contains large amounts of pollutants, including pesticide residues, excessive fertilizers, and heavy metals, causing serious impacts on the ecological environment.
