Problems solved by technology

Removing the contaminated soil for remediation requires a large amount of work and is not suitable for large-scale soil remediation
In-situ restoration is often carried out directly by adding soil remediation agents, but since the components of soil remediation agents are different, and after adding soil remediation agents, the reaction conditions of soil remediation agents cannot be controlled, making the efficiency of soil remediation not tall

Abstract

The invention discloses a maltodextrin based soil remediation complexing agent. The maltodextrin based soil remediation complexing agent comprises the following raw materials by weight: 40-65 parts ofmaltodextrin, 10-30 parts of organic acid, 10-25 parts of initiator, 0.5-1.5 parts of compound microorganism bacterium agent, 2-5 parts of activated carbon, 10-20 parts of amino acid. The invention aims at providing the maltodextrin based soil remediation complexing agent, the remediation efficiency of the maltodextrin based soil remediation complexing agent is high, the water-retaining propertyand the air permeability of the soil is good, the soil remediation effect is good, the content of the heavy metal like cadmium is reduced to be lower than the limit of detection, the usage amount of asoil remediation agent is low, and the cost is reduced.

Description

technical field [0001] The invention relates to the technical field of soil remediation, in particular to a complexing agent for soil remediation based on maltodextrin. Background technique [0002] In recent years, with my country's economic development and urban layout adjustment, many fertilizer factories, pesticide factories, chemical factories and other enterprises that discharge a large amount of organic waste have been relocated from the city center. The concentration of organic pollutants in some soils is very high, and some pollutants Even migrate to groundwater and spread to cause larger-scale pollution. According to relevant national regulations, these organic contaminated soils need to undergo environmental assessment and be remediated according to the pollution situation before they can be put into use again. Therefore, it is very urgent to carry out research on remediation of organic polluted soil and develop key technologies for remediation of organic polluted...
