Abstract
The invention discloses a soil remediation agent and a preparation method thereof. The soil remediation agent is prepared from the following formula components in parts by mass: 15 to 25 parts of waste clay subjected to oil extraction, 5 to 15 parts of bacillus subtilis, 6 to 8 parts of lactic acid bacteria, 3 to 5 parts of sulfur-containing compound, 4 to 8 parts of sodium-based bentonite, 14 to 18 parts of flammulina velutipes fungus chaff, 3 to 5 parts of magnesium aluminum silicate, 3 to 5 parts of niter, 3 to 5 parts of pyrethrum, 14 to 18 parts of derris trifoliate, 4 to 8 parts of humic acid, 2 to 4 parts of microbial agent and 6 to 10 parts of hydrogen peroxide. According to the soil remediation agent and the preparation method thereof disclosed by the invention, spent bleaching clay can be recycled; meanwhile, the soil remediation agent further has excellent functions of adsorbing and immobilizing heavy metal ions, and is high in added value, simple in preparation and low in cost.
Description
technical field [0001] The invention relates to the field of herbicides, in particular to a soil remediation agent and a preparation method thereof. Background technique [0002] Soil pollution has become a worldwide problem, and heavy metal pollution has become the "invisible killer" of my country's agricultural products. Excessive use of chemical fertilizers will cause soil acidification, which in turn will induce an increase in the activity of heavy metal ions in the soil. Every time the soil pH value drops by one unit, the activity of heavy metal cadmium will increase by 100 times, which will increase the risk of diseases such as bone pain disease. "The biggest characteristics of agricultural non-point source pollution are concealment, long-term and scattered nature. It is consciously or unconsciously produced in various processes of agricultural production, and it is more troublesome to deal with. According to preliminary statistics, there are about 1,000 farmlands pol...
