Abstract

The invention belongs to the field of oil remediation, and especially relates to a biochar improved material for soil remediation. In view of the problem of poor soil remediation effect caused by no effective remediation of heavy metal contamination of soil during conventional soil remediation, the following scheme is provided: the biochar improved material for soil remediation comprises the following raw materials, by weight: 20-30 parts of straw powder, 2-6 parts of quicklime, 25-35 parts of a microbial agent, 30-40 parts of biomass charcoal, 2-5 parts of dipotassium hydrogen phosphate, 4-7parts of ammonium sulfate, 5-9 parts of organosilicon, 10-15 parts of lignin, 3-7 parts of quick-acting calcium, 5-9 parts of rock phosphate, 6-11 parts of amino acid, 5-10 parts of peat soil, 11-14 parts of diatomite, 1-4 parts of humic acid, and 7-12 parts of chitosan. The biochar improved material for soil remediation can effectively remedy the soil, effectively remedy the heavy metal pollutionof the soil, improve the soil and increase the fertility. A preparation method is simple.

Description

technical field [0001] The invention relates to the field of soil restoration, in particular to a biochar improvement material for soil restoration. Background technique [0002] Soil remediation refers to the use of physical, chemical and biological methods to transfer, absorb, degrade and transform pollutants in the soil, reducing its concentration to an acceptable level, or converting toxic and harmful pollutants into harmless substances. Fundamentally speaking, the technical principles of contaminated soil remediation can include: (1) Change the form of pollutants in the soil or the way they combine with the soil to reduce their mobility and bioavailability in the environment; ( 2) Reduce the concentration of harmful substances in the soil. The soil is originally a natural shelter and purification treatment place for various wastes. The soil accepts pollutants, which does not mean that the soil is polluted. Only when the soil contains too many pollutants, it affects and...
