Iron and steel enterprise contaminated soil remediation agent and use method thereof

Abstract

The invention discloses an iron and steel enterprise contaminated soil remediation agent and a use method thereof. The formula comprises the following components by mass percentage: 15-25% of quick lime, 20-30% of bentonite, 15-25% of calcium superphosphate, 10-20% of a calcium magnesium phosphate fertilizer, 2-4% of ground phosphate rock, 10-20% of biomass charcoal, 1-3% of an organic fertilizer,5-10% of corn straw, 0.5-1% of a catalyst and 0.5-1% of a defoaming agent. The use method includes: step 1, reagent preparation; step 2, reagent mixing; step 3, reagent cartonning; step 4, application into soil; step 5, soil plowing; and step 6, appliance cleaning. According to the invention, the soil remediation agent is safe and reliable, the process is simple and rigorous, can replace other expensive soil remediation agent production processes, the effect is remarkable, the raw materials are cheap and the cost is low, and the production cost is greatly saved, thus facilitating processing and production.

Description

technical field [0001] The invention relates to the technical field of remediation of contaminated soil in iron and steel enterprises, in particular to a remediation agent for contaminated soil in iron and steel enterprises and a use method thereof. Background technique [0002] With the massive development and utilization of national mineral resources and the rapid development of industrial production, iron and steel enterprises of different sizes and scales have been built in various places to produce steel to meet national needs. It is easy to pollute the surrounding soil, leading to the increase of heavy metals in the soil, such as the increase of harmful elements such as Cu, Hg and As, which require soil remediation agents to degrade and eliminate heavy metal elements in the soil. Traditional soil remediation agents are expensive to make and cannot be well mixed with the land. , leading to the inability to degrade and eliminate heavy metal elements in the soil, and the ...

[0002] With the massive development and utilization of national mineral resources and the rapid development of industrial production, iron and steel enterprises of different sizes and scales have been built in various places to produce steel to meet national needs. It is easy to pollute the surrounding soil, leading to the increase of heavy metals in the soil, such as the increase of harmful elements such as Cu, Hg and As, which require soil remediation agents to degrade and eliminate heavy metal elements in the soil. Traditional soil remediation agents are expensive to make and cannot be well mixed with the land. , leading to the inability to degrade and eliminate heavy metal elements in the soil, and the production process is time-consuming and laborious, which is not conducive to production; in view of these defects, it is necessary to design a remediation agent for contaminated soil in iron and steel enterprises and its use method
