Quick-acting soil heavy metal restoration agent

Abstract

The invention discloses a quick-acting soil heavy metal restoration agent, which is prepared from the following raw materials (by weight): 5-7 parts of stalactite, 6-7 parts of calcium lactate, 3-5 parts of rosin, 26-29 parts of wheat bran, 34-36 parts of biogas residue, 6-9 parts of potassium citrate, 76-80 parts of seeded sunflower disc, 35-38 parts of enteromorpha prolifera, 16-18 parts of kaolin, 10-12 parts of calcium carbonate, 30-34 parts of slash pine needle and a proper amount of water. According to the invention, a charcoal matrix prepared from production waste is used as a main raw material of the soil restoration agent. With the addition of potassium citrate, activity of functional groups in the restoration agent is raised. The functional groups interact with water and heavy metal in soil to rapidly form conversion energy. Thus, pH value of the soil is adjusted to neutral level, and insufficient trace elements are supplemented. Through fermentation, the raw materials such as biogas residue are rapidly absorbed by soil, thus improving soil fertility potential and restoring the eco-balance. Then, the contaminated soil becomes suitable for plantation within a short period of time.

Description

technical field [0001] The invention relates to the technical field of soil restoration, in particular to a quick-acting soil heavy metal restoration agent. Background technique [0002] The sources of heavy metal pollution in my country mainly include industrial "three wastes" discharge, seepage of household garbage, household coal burning, and vehicle exhaust emissions. Industries such as electroplating, plastics, chemicals, and mineral smelting and processing are the main industrial sources of heavy metals. The release of coal combustion is also one of the important causes of soil heavy metal pollution. Motor vehicle exhaust can also significantly cause heavy metal pollution in the soil on both sides of the road. The content of some heavy metal elements in municipal solid waste exceeds the standard, and long-term stacking will also cause heavy metals to leak into the soil, resulting in an increase in local heavy metal content in regional soil. In addition, the long-term ...

Problems solved by technology

Heavy metal elements are easy to combine with the sulfhydryl group in the active part of the enzyme, and the metal element will replace the essential elements in the sulfur protein, such as Mg2+, Ca2+ and other biologically necessary elements. The antioxidant system in the system wreaks havoc

[0004] At present, the remediation technology of heavy metal-contaminated soil mainly adopts chemical means, but a large number of chemical agents used in the remediation process can easily cause soil re-pollution
