Abstract

The invention belongs to the technical field of soil remediation, and particularly relates to a heavy metal soil remediation agent which is prepared from, by weight, oyster shells, organic bacterial manure, fish meal, alkaline residues, alginic acid, silicon fertilizer, zeolite, charcoal, phosphate, nitrilotriacetic acid, ethylenediamine disuccinic acid, wormcast and distilled water. The organic bacterial fertilizer comprises livestock and poultry manure, water, fermented finished product compound bacteria and vegetable oil residues, the pH value of soil can be increased through the alkaline residues, meanwhile, calcium and magnesium in the soil can be supplemented, the biological activity of the soil can be improved through alginic acid, the soil structure can be generated, the pore space in the soil can be improved, and the soil quality can be improved. The soil toxicity can be reduced through the organic bacterial manure, the oyster shells, the fish meal, the zeolite and the charcoal, the solubility of heavy metals in the soil can be increased through the nitrilotriacetic acid, the ethylenediamine disuccinic acid and the wormcast, and the heavy metals are promoted to be transferred from the deep position of the soil to the surface of the soil.

Description

Technical field [0001] The present invention relates to the field of soil repair technology, in particular a heavy metal soil repair agent and a preparation method thereof. Background technique [0002] China's soil environment is generally not optimistic, and the national soil pollution over the standard is 16.1%, and the soil environmental quality of cultivated land is more worrier while the soil environmental problems in the industrial and mining industry. In the face of the severe situation of soil pollution, soil repair is a technical measure to restore normal functions of pollution. In the soil inorganic contaminant, it is more prominent in heavy metals, mainly due to heavy metals that cannot be decomposed for soil microorganisms, and easy to accumulate. Conversion to a more toxic methyl compound, and even the food chain is accumulated in the human body in human body, severe harm Human health. [0003] The existing for soil repair includes a variety of methods such as biolo...
