Abstract

The invention provides a repair agent for vanadium pollution and a preparation method thereof. The repair agent is prepared from the following raw materials in parts by weight: 45-55 parts of chickenmanure, 25-35 parts of sepiolite, 3-5 parts of polyacrylamide, 3-5 parts of urea, 5-7 parts of phosphoric acid, 1.5-2.5 parts of potassium sulphate, 0.5-1.5 parts of ferric lignin and 2-4 parts of humic acid. According to the repair agent for vanadium pollution, a soil structure can be improved while the contents of heavy metal and associated heavy metal in soil can be lowered, the water-retainingproperty and the air permeability of the soil can be improved, and the repair agent is suitable for the growth of crops.

Description

technical field [0001] The invention relates to the technical field of restoration agents, in particular to a restoration agent for vanadium pollution and a preparation method thereof. Background technique [0002] As an essential trace element for humans and animals, metal vanadium plays a very important role in life systems. Vanadium deficiency can lead to lesions in the heart, blood pressure, bones, and sense of taste, while vanadium poisoning can seriously affect the health of the kidneys, spleen, and intestines. The content of vanadium in the human body is usually obtained through food, and the content of vanadium in food is usually closely related to the soil where crops are grown. Excessive vanadium content in the soil will cause excessive vanadium content in crops, which in turn leads to vanadium poisoning in humans. [0003] At present, the treatment of heavy metal vanadium-contaminated soil mainly adopts chemical remediation technology for remediation. For example...
