Embodiment Construction
[0022] A soil remediation agent for inhibiting the diffusion and pollution of heavy metals, made of the following parts by weight (kg) of raw materials: fine sand 25, charcoal 20, magnesium sulfate 2, sheep bone meal 14, calcium dihydrogen phosphate 8, seedless sunflower plate 82, Switchgrass branches and leaves 33, kaolin 22, calcium carbonate 6, slash pine needles 30, appropriate amount of water.
[0023] The specific steps for preparing the soil heavy metal repair agent are as follows:
[0024] (1) Dry the seedless sunflower pan and switchgrass branches and leaves in the sun. After crushing, they are mixed and placed in an oven at 50°C for 15 hours. The resulting slag is placed in a closed furnace at a speed of 20°C / min. Raise the temperature to 550°C and keep it for 90 minutes, then take it out when the temperature drops to 57°C to obtain biochar;
[0025] (2) After mixing the kaolin and calcium carbonate, place it in a calciner, calcinate at 570°C for 40 minutes, cool to room t...
