Embodiment Construction

[0022] A nutritional soil heavy metal restoration agent, made of the following raw materials in parts by weight (kg): mushroom slag 28, straw 16, sawdust 10, diammonium phosphate 7, sodium phytate 2, bentonite 5, medical stone powder 3, detox Seed sunflower plate 80, pig manure 28, kaolin 19, calcium carbonate 8, slash pine needles 28, 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 sunflower dish and pig manure with the seeds removed in the sun, crush them, mix them and put them in an oven for 10 hours at 60°C, put the resulting slag in a closed furnace at a speed of 20°C / min Raise the temperature to 600°C and keep it warm for 90 minutes, then take it out when the temperature drops to 60°C to obtain biochar;

[0025] (2) Put kaolin and calcium carbonate in a calciner, calcinate at 660°C for 40 minutes, cool to room temperature and take out to obtain calcined powde...

Abstract

The invention discloses a nutritional soil heavy metal restoration agent which is prepared from the following raw materials in parts by weight: 28-30 parts of fungus dreg, 16-19 parts of straw, 10-11 parts of wood dust, 7-9 parts of diammonium phosphate, 2-3 parts of sodium phytate, 5-7 parts of bentonite, 3-5 parts of medical stone powder, 80-90 parts of deseeded sunflower head, 28-32 parts of pig manure, 19-21 parts of kaolin, 8-9 parts of calcium carbonate, 28-30 parts of slash pine needle and a right amount of. The soil restoration agent can stabilize, enhance and balance the physical functions of the soil. The added fungus dreg, straw and the like increase the organic content of the soil. The medical stone powder, bentonite and the like enhance the air permeability of the soil, and relieve the soil hardening. The soil restoration agent has strong removal effects on chromium, cadmium and other pollutants in the soil, increases the soil fertility, and enhances the comprehensive properties of the soil.

Description

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