The invention discloses a heavy
metal remediation agent formula for
soil remediation, which comprises the following raw materials: deseeded
sunflower heads, switchgrass branches and leaves, kaolin,
calcium carbonate, an
organic fertilizer, pinus elliottii needle leaves,
polyaluminum chloride, polyaluminum
ferric chloride, bacterial strains and a proper amount of water. Through addition of an
organic fertilizer, a large amount of
organic matter and nutritional ingredients can be supplied to the contaminated soil, the potential
fertility of the contaminated soil is improved, the buffer performance of the soil is improved through modified
calcination of kaolin in combination with
calcium carbonate, the soil is loosened, and by adding
polyaluminum chloride and polyaluminum
ferric chloride, theactivity of heavy
metal in the soil and the effectiveness of plants are improved; the utilization value of the soil is greatly increased, and the
soil remediation is safe and effective through the addition of strains. The preparation method of a formula of a heavy
metal repairing agent for
soil remediation is convenient to operate,
environmentally friendly and harmless, and the prepared heavy metal repairing agent is low in cost, obvious in effect and suitable for wide application and popularization.
