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

Embodiment Construction

[0022] A tourmaline-assisted soil heavy metal repair agent, made of the following parts by weight (kg) of raw materials: garden soil 12, sweet potato powder 24, sodium dihydrogen phosphate 4, tourmaline powder 14, peanut cake powder 29, nickel sulfate 1, and Seed sunflower pan 82, pig farm manure 26, kaolin 20, calcium carbonate 10, slash pine needles 27, water appropriate.

[0023] The specific steps for preparing the soil heavy metal repair agent are as follows:

[0024] (1) The seedless sunflower pan and pig farm manure were dried in the sun, crushed and mixed and placed in an oven at 50°C for 10 hours. The resulting slag was placed in a closed furnace at 20°C / The temperature is increased to 540°C at a rate of 1 min, and kept for 90 minutes, and then taken out when the temperature is lowered to 60°C to obtain biochar;

[0025] (2) The kaolin and calcium carbonate are mixed and placed in a calciner, calcined at 600°C for 40 minutes, cooled to room temperature and taken out to obt...

Abstract

The invention discloses a tourmaline-assisted soil heavy mental restoration agent, which is prepared from the following raw materials (by weight): 12-14 parts of garden soil, 24-26 parts of sweet potato powder, 4-5 parts of sodium dihydrogen phosphate, 14-16 parts of tourmaline powder, 29-31 parts of peanut meal, 1-2 parts of nickel sulfate, 82-86 parts of seeded sunflower disc, 26-30 parts of manure of a pig farm, 20-24 parts of kaolin, 10-12 parts of calcium carbonate, 27-29 parts of slash pine needle and a proper amount of water. In allusion to heavy metal pollution and low bioavailability of persistent organic pollutants in soil, with assistance of organic materials such as tourmaline, peanut meal, sweet potato powder and the like, reproduction of soil microorganisms is promoted, bioavailability of pollutants is raised, and restoration efficiency of heavy metal and organic pollutants in soil by soil microorganisms is further enhanced. Pollutant content of restored soil is lower than the national standard. The product is suitable for promotion and application.

Description

Technical field [0001] The invention relates to the technical field of soil restoration, in particular to a tourmaline-assisted soil heavy metal restoration agent. Background technique [0002] The sources of heavy metal pollution in my country mainly include industrial "three wastes" emissions, domestic waste seepage, household coal burning, and automobile exhaust emissions. Electroplating, plastics, chemicals, mineral smelting and processing industries are the main industrial sources of heavy metals. The release of coal is also one of the important causes of heavy metal pollution in the soil. 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 increased local heavy metal content in the regional soil. In addition, long-term unreasonable use of ch...
