Device for in-situ treatment of river sediment heavy metal pollution

Abstract

The invention relates to a device for in-situ treatment of river sediment heavy metal pollution. The device comprises a supporting and fixing structure, a fixed mounting plate and purification treatment structures, the supporting and fixing structure is located on the outer side of the fixed mounting plate, and the purification treatment structures are located on the upper and lower sides of the fixed mounting plate. The supporting and fixing structure comprises floating platforms located on the left side and the right side of the fixed mounting plate, stabilizing blocks are fixedly connected to the inner bottom walls of the two floating platforms, up-down telescopic rods are fixedly connected to the inner bottom walls of the two floating platforms, output shafts of the up-down telescopic rods are fixedly connected with a fixing plate, and sliding blocks are fixedly connected to the left side and the right side of the fixing plate correspondingly. According to production turn-over equipment for a circuit board for a television, the floating platforms support a sludge treatment device to ensure normal operation when water exists in a river channel, the operation range is widened, the operation safety is ensured, the working efficiency is greatly improved, and the stabilizing block plays a role in supporting the fixing plate and provides good stability for the fixing plate during movement.

Description

technical field [0001] The invention relates to the technical field of metal pollution treatment devices, in particular to a device for in-situ treatment of heavy metal pollution in river bottom mud. Background technique [0002] Heavy metal pollution refers to environmental pollution caused by heavy metals or their compounds, mainly caused by human factors such as mining, waste gas discharge, sewage irrigation and the use of products with heavy metals exceeding the standard. The original meaning of heavy metals refers to metals with a specific gravity greater than five, including gold, silver and copper. , iron, lead, etc. Heavy metal pollution is different from other organic compound pollution. Many organic compounds can be purified or eliminated through physical, chemical or biological purification in nature itself, while heavy metals are enriched and difficult to Degradation in the environment, whether the metal in the water body is beneficial or harmful depends not only...

AI Technical Summary

Problems solved by technology

[0004] Aiming at the deficiencies of the prior art, the present invention provides a device for in-situ treatment of heavy metal pollution in river bottom mud, which has the advantages of thorough purification, complete crushing and suction of river bottom mud, and solves the problem of existing in-situ treatment of river bottom mud. The equipment polluted by heavy metals has the problem that the purification is not thorough enough, and the river silt cannot be completely crushed and sucked out, resulting in the inability to purify the river silt in all aspects.
