Abstract

The invention relates to an efficient heavy metal soil restoration agent. The efficient heavy metal soil restoration agent is prepared from the following raw materials in parts by weight: 3-7 parts of phosphate compounds, 9-16 parts of straw, 3-7 parts of medical stone, 12-20 parts of polyamide fiber, 5-8 parts of sodium bismuthate, 6-13 parts of sodium sulfide, 1.2-2.5 parts of Bacillus pasteurii spore powder, 6-25 parts of turf powder, 0.3-0.6 part of powdery bacterial powder carrier, 0.5-1.2 parts of fruit residues, 0.1-0.25 part of saw dust, 3-6 parts of calcium oxide and 2-5 parts of a magnesium-containing preparation. By virtue of the efficient heavy metal soil restoration agent, polluted soil can be effectively restored in a short time, heavy metals are inactivated, the soil restoration function is comprehensive and strong, and the soil environment can be effectively improved.

Description

technical field [0001] The invention relates to an efficient heavy metal soil repair agent. Background technique [0002] The national survey of sewage irrigation areas organized by the Ministry of Agriculture shows that China's current sewage irrigation area is about 1.4 million hm2, and the area of ​​land polluted by heavy metals accounts for 64.8% of the total area of ​​sewage irrigation, of which the lightly polluted area accounts for 46.7%, and the moderately polluted area accounts for 9.7%. %, seriously polluted area accounted for 8.4%. With the advancement of urbanization in China, chemical pollution has become a major source of pollution. Benzene, phenol, phosphorus organic pollution and cadmium, arsenic, lead, chromium, mercury and other heavy metals are seriously polluted. While polluting the air and water, they have also become long-standing "cancers" in the soil. Industry insiders pointed out that whether heavy metals pollute water bodies or pollute the atmosph...
