Vehicle-mounted in-situ remediation equipment for heavy metal pollution of farmland soil

Abstract

The invention relates to ecological environment pollution treatment and mechanical equipment in the engineering application fields thereof, in particular to vehicle-mounted in-situ remediation equipment for heavy metal pollution of farmland soil, which mainly comprises a vehicle-mounted system, a push bucket material taking system and a magnetic recovery system. a vehicle frame of the vehicle-mounted system is connected with a push bucket through a support rod, the middle part of the push bucket is provided with a material collecting port, and soil solution is extracted to a feeding port of the magnetic recovery system through a middle pipe by using a pipeline pump positioned in the push bucket material taking system; in the magnetic recovery system, a magnetic recovery machine is driven by a magnetic separation motor, magnetic heavy metal chelates in the soil solution are adsorbed on a magnetic roller, are scraped to a fine material groove by a scraper device, and drop to a recovery groove by a fine material pipe. The equipment can fill the technical equipment blank field of new chelating magnetic removal materials in engineering application, in particular to a soil solution system. And a mobile in-situ rapid remediation mode for soil heavy metal pollution treatment is achieved.

Description

technical field [0001] The invention relates to mechanical equipment in the field of ecological environment pollution control and its engineering application, in particular to a vehicle-mounted in-situ restoration equipment for heavy metal pollution in farmland soil. Background technique [0002] Soil is the basis of human activities and survival, and the deterioration of soil environment directly threatens the safety of human food, residence and activities. Compared with common air pollution, water pollution, and industrial solid waste, soil pollution is invisible and concealed. It will lead to degradation of soil fertility, reduction of crop yield and quality, and through cumulative absorption, it will be harmful to human health after entering the food chain. more seriously, when the toxic substances in the soil accumulate to a certain extent, they can directly cause harm to human health through volatilization or use. [0003] At present, the technical means used for soil...

AI Technical Summary

Problems solved by technology

[0005] However, in the soil solution system where the chelation magnetic removal technology is most widely used, due to the heterogeneity of the soil solution system, it is difficult to develop or integrate the separation device, and it is difficult to realize the in-situ repair of the matching agricultural machinery. Technical equipment is almost blank, which greatly restricts the large-scale promotion of chelated magnetic removal new materials in engineering applications

In particular, the integrated mechanical equipment for separating and removing heavy metal pollutants in the soil solution system through continuous operation is still blank at present.
