Soil contamination repairing agent

Abstract

The invention discloses a soil contamination repairing agent. The soil contamination repairing agent is prepared from, by weight, 25-35 parts of bentonite, 17-20 parts of poly diallyldimethylammonium chloride, 15-20 parts of mica, 10-15 parts of nano waterborne adhesive, 6-12 parts of chitosan fibers, 0.004-1 part of polyethylene glycol acrylate, 24-36 parts of anionic polyacrylamide, 12-22 parts of monopotassium phosphate, 5-11 parts of nano-hydroxyapatite, 25-45 parts of culture pond sludge, 11-19 parts of bamboo pulp, 6-14 parts of ferric sodium edelate, 11-19 parts of sugar alcohol magnesium, 0.8-1.8 parts of enzyme microorganisms, 45-65 parts of Maya blue powder and 1-3 parts of mixed microbes. The repairing agent has the functions of soil contamination treatment, soil improvement, degradation of pesticide and fertilizer residues, increase of soil nutrients and the like.

Description

technical field [0001] The invention relates to the field of soil remediation, in particular to a soil pollution remediation agent. Background technique [0002] With the development of the economy, environmental pollution is becoming more and more serious, and soil pollution is different from other pollution, mainly manifested as hidden pollution, which has a certain hysteresis and is not intuitive. In particular, heavy metal pollution can generally only be detected through testing, so treatment is difficult and time-consuming. In addition, with the large-scale application of chemical fertilizers and pesticides, the soil shows serious compaction, increased pesticide residues, eutrophication, and reduced agricultability; with the development of large-scale livestock and poultry farming, traditional organic fertilizers for livestock and poultry A series of potential hidden dangers such as antibiotic residues have emerged, which have seriously affected agricultural production...

Problems solved by technology

[0002] With the development of the economy, environmental pollution is becoming more and more serious, and soil pollution is different from other pollution, mainly manifested as hidden pollution, which has a certain hysteresis and is not intuitive.

Especially heavy metal pollution, generally can only be found through testing, so the treatment is difficult and time-consuming

In addition, with the large-scale application of chemical fertilizers and pesticides, the soil shows serious compaction, increased pesticide residues, eutrophication, and reduced agricultability; with the development of large-scale livestock and poultry farming, traditional organic fertilizers for livestock and poultry A series of potential hidden dangers such as antibiotic residues have emerged, which have seriously affected agricultural production, and at the same time affected the quality and safety of agricultural products and food safety

[0003] Soil remediation is a technical measure to restore polluted soil to normal functions. Currently, commonly used soil remediation methods include physical, chemical and microbial methods. Although physical and chemical methods have direct effects and quick results, their sustainability is poor, and the method or When the dosage is slightly inappropriate, not only the repair effect will not be achieved, but also new pollution will be brought. The composite method is comprehensive, comprehensive, and has strong lasting effect. It will also provide nutrients while repairing, avoiding the barrenness of the soil, and will not cause pollution. will have any adverse effects
