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 microbial soil heavy metal remediation agent, made of the following raw materials in parts by weight (kg): wheat bran 14, cinder 8, JT composite microbial agent, potassium chloride 2, straw ash 30, ammonium bicarbonate 6, seed removed Sunflower plate 75, vermicompost 35, kaolin 16, calcium carbonate 6, slash pine needles 27, appropriate amount of water.

[0023] The concrete steps of the preparation of described soil heavy metal restoration agent are as follows:

[0024] (1) Dry the seedless sunflower tray and vermicompost in the sun, crush them and mix them in an oven for 12 hours at 55°C. Raise the temperature to 500°C and keep it warm for 100 minutes, then take it out when the temperature drops to 60°C to obtain biochar;

[0025] (2) Mix kaolin and calcium carbonate and place in a calciner, calcinate at 650°C for 40 minutes, cool to room temperature and take out to obtain calcined powder for later use;

[0026] (3) Mix the biochar obtained in step 1 with the calc...

Abstract

The invention discloses a microbial soil heavy metal restoration agent which is prepared from the following raw materials in parts by weight: 14-15 parts of wheat bran, 8-10 parts of coal slag, JT composite microbial inoculant, 2-3 parts of potassium chloride, 30-35 parts of straw ash, 6-7 parts of ammonium bicarbonate, 75-85 parts of deseeded sunflower head, 35-40 parts of wormcast, 16-18 parts of kaolin, 6-8 parts of calcium carbonate, 27-29 parts of slash pine needle and a right amount of water. By ading the composite microbial inoculant, the soil restoration agent has the function of restoring the defects in the existing soil ecosystem, and can degrade organic pollutants. The wheat bran, coal slag and other fermentation materials provide adequate nutrient sources for microbe growth, and also provide an excellent growing space for the microbes due to the loose structure, thereby accelerating the microbial reproduction and enhancing the restoration effect of the restoration agent.

Description

technical field [0001] The invention relates to the technical field of soil restoration, in particular to a microbial 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 unr...
