Roller blind type farmland water return pesticide purifier based on photocatalytic degradation

Abstract

The invention relates to a roller blind type farmland water return pesticide purifier based on photocatalytic degradation. The purifier structurally comprises a left fixed pile, a right fixed pile, astorage box, an upper winding shaft, rocking handles, a photocatalyst-loaded mesh blind, a lower winding shaft, a loading magnet and a bottom fixing iron bar, wherein a bearing A is arranged at the center of the outer surface of the side surface of the left end of the storage box; a bearing B is arranged at the center of the outer surface of the side surface of the right end of the storage box; the upper winding shaft passes through the centers of the side surfaces of the left and right ends of the storage box; the upper winding shaft penetrates through the left and right ends of the storage box; the left end of the upper winding shaft is connected with the upper end of the left fixed pile through the bearing A 10-1; the right end of the upper winding shaft is connected with the upper endof the right fixed pile through the bearing B; the rocking handles are arranged at two ends of the upper winding shaft; the upper end of the photocatalyst-loaded mesh blind is connected with the upperwinding shaft; the lower winding shaft is arranged at the lower end of the photocatalyst-loaded mesh blind; and the loading magnet is arranged on the lower winding shaft.

Description

technical field [0001] The invention relates to a rolling screen type farmland dewatering pesticide purifier based on photocatalytic degradation, and belongs to the technical field of farmland pesticide non-point source pollution control. Background technique [0002] Pesticides are one of the most important means of production and play an important role in improving crop yield and quality. However, the excessive application of pesticides results in residues in farmland soil, crop leaves, and the atmosphere, becoming one of the widespread pollutants in the environment, posing a threat to human health and ecological security. The transfer route of farmland pesticide pollution is mainly through the return of farmland water after irrigation, and reducing the pesticide residues in the return water of farmland is the key link to block the spread of pesticides to the water environment. [0003] Among the many technologies for removing pesticide residues in the polluted environmen...
