Problems solved by technology

However, the phytoremediation method takes a long time to repair, and the curing / stabilization repair technology is reversible, making it difficult to restore the original state. Electrodynamic repair will acidify the soil under acidic conditions, causing secondary damage to the soil, and chemical leaching repair will easily damage soil fertility. , and the use of water for adsorption and transfer can realize green treatment without any new pollution

Abstract

The invention provides a soil heavy metal in-situ sensing monitoring, adsorption transfer and precipitation recovery system. The system comprises a reaction chamber group, a treatment tank and a precipitation pump. The treatment tank is connected to the reaction chamber group through a pipeline, and the precipitation pump is respectively connected to the treatment tank and the reaction chamber group through pipelines; the reaction chamber group comprises a plurality of reaction cavities with the same structure, and the reaction cavities are connected through pipelines; the reaction cavities are internally equipped with filter membranes, on which a plurality of enzyme membrane biosensors are loaded, and the enzyme membrane biosensors are connected to a controller through circuits. The soilheavy metal in-situ sensing monitoring, adsorption transfer and precipitation recovery system provided by the invention can realize in-situ real-time monitoring, does not need pretreatment on a soil sample, is simple to operate and low in operation cost, can provide continuous analysis, and meets the actual requirements of rapid monitoring.

Description

technical field [0001] The invention belongs to the field of monitoring and prevention of polluted soil, and in particular relates to a soil heavy metal in-situ sensing monitoring, adsorption transfer, precipitation recovery system. Background technique [0002] With the rapid development of industry and agriculture, the problem of soil heavy metal pollution is very serious. Heavy metals enter the soil in various forms, destroying the ecological environment of the soil, causing secondary disasters such as groundwater pollution, and causing great harm to animals, plants and human health. Therefore, it is particularly important to quickly, real-time, and accurately monitor and restore heavy metal content in soil. important. [0003] Currently, the commonly used detection methods for contaminated soil mainly include in-situ monitoring method and laboratory test method. The in-situ monitoring method has attracted much attention because of its advantages of simple operation, fa...
