Abstract

The invention discloses an organophosphorus-polluted soil remediation material, which comprises the following components in parts by weight: 12-24 parts of desalted river sand, 10-16 parts of rutile titania, 6-10 parts of barium sulfate, 5-8 parts of zinc gluconate, 5-10 parts of potassium formate, 6-8 parts of magnesium ascorbyl phosphate, 5-8 dipotassium glycyrrhizinate, 5-8 parts of B-eucryptite, 1-3 parts of EDTA tetrasodium, 5-10 parts of plain white, 2-5 parts of sodium oleate, and 1-3 parts of dried alum. The soil remediator can effectively enhance the remediation performance of the organophosphorus-polluted soil by adding dipotassium glycyrrhizinate, magnesium ascorbyl phosphate and potassium formate; and the remediator is easily available for raw materials, safe and environment-friendly, and has good economic values and social values.

Description

technical field [0001] The invention relates to the technical field of soil treatment, in particular to a restoration material for organic phosphorus polluted soil and a preparation method thereof. Background technique [0002] Organophosphorus pesticides are organic compounds containing organophosphorus pesticides used to prevent and control plant diseases, insects, and pests. There are many kinds of organophosphorus pesticides, which can be divided into three categories according to their toxicity: high toxicity, moderate toxicity and low toxicity. With the use of organophosphorus pesticides, the organic phosphorus content in the soil is too much, exceeding the self-purification capacity of the soil, which will cause changes in the composition, structure and function of the soil, inhibit microbial activities, and cause harmful substances or their decomposition products in the soil. Gradually accumulate through "soil → plant → human body", or indirectly absorbed by the hum...
