Drivepipe type purification device capable of efficiently removing pesticide residuals of agricultural field water body

Abstract

The invention provides a drivepipe type purification device capable of efficiently removing pesticide residuals of an agricultural field water body. The drivepipe type purification device structurally comprises a hollow organic glass outer tube, a PVC transparent inner tube, an organic glass tank, an organic glass clapboard, a moving type arresting barrier and a clamping trough, wherein the PVC transparent inner tube is arranged in the hollow organic glass outer tube, and the moving type arresting barriers are arranged on two ends of the hollow organic glass outer tube; the hollow organic glass outer tube and the PVC transparent inner tube are assembled to form a purification drivepipe which is positioned in the organic glass tank, the clamping trough is arranged on the inner wall of the organic glass tank, and the organic glass clapboard is fixedly arranged on the clamping trough; a nanocatalyst loading layer is covered on the outer surface of the hollow organic glass outer tube, and pesticide degradation bacteria loading layers are arranged on the inner surface and the outer surface of the PVC transparent inner tube. The drivepipe type purification device has the advantages of improving the efficiency of removing pesticide residuals of an agricultural field water body, being convenient to apply, low in cost and capable of being repeatedly used for many times.

Description

technical field [0001] The invention relates to a casing type cleaning device for efficiently removing pesticide residues in farmland water, and belongs to the technical field of pesticide non-point source pollution control. Background technique [0002] Pesticide pollution has become the most influential type of organic pollution in my country, and it is persistent and agricultural products are enriched; with the long-term and large-scale application of pesticides, pesticide pollution in farmland receding water is becoming more and more serious, and it has become one of the important sources of agricultural non-point source pollution , Farmland polluted water enters rivers, lakes and other water ecosystems, affecting the growth of aquatic organisms and threatening human health. Effective removal of pesticide residues in farmland water is of great significance to ensuring water environment safety. [0003] In recent years, research on the removal of pesticide residues in wate...

AI Technical Summary

Problems solved by technology

[0004] With the development of photocatalytic technology and the research and development of a variety of new nanomaterials, photocatalytic removal of pesticide pollution has great application potential; There are problems such as difficult recycling, low utilization rate, and potential environmental hazards, and nano-catalysts need good light source coverage to function. However, the existing carriers loaded with nano-photocatalysts are mostly porous carbon and other carrier types with poor light transmission, which cannot be used Nano photocatalysts fully function

[0005] In addition, the existing relatively mature farmland pesticide pollution control technologies (such as artificial wetland technology) generally have problems such as large area, high cost, and difficult maintenance in actual farmland applications, and most of the technologies themselves choose one method to deal with the pollution. Remediation of pesticide-contaminated water bodies (such as microbial remediation method), due to the single application of remediation methods and a series of unstable factors, it is difficult to promote the use of a large area; It is imminent to implement a pesticide purification device with simple and stable performance
