Problems solved by technology
[0003] With the development of industry and the continuous improvement of living standards, human beings pollute the soil more and more seriously. Soil pollution has become a global problem. All countries are trying various solutions. The related methods include physical, Chemical, biological, etc., but these methods have no ideal effect, therefore, there is an urgent need for a new technical solution to solve the technical problems of industrial wastewater treatment

Embodiment 1
[0010] A method for remediating contaminated soil. The method for remediating contaminated soil is specifically as follows: 1) prepare rice straw, corn stalks, and peanut stalks, and mix them according to the mass ratio of 3:4:1; Stir and crush in the pulverizer, the crushing time is 10-15 minutes, and the crushed particle size is 10mm; 3) Add 50% of the total mass of water for mixing, 4) Apply the mixture to the soil, fertilize, irrigate, and add quicklime , adjust the pH value of the soil to 7-8, so that the pollutants in the soil are aerobically degraded in the upper layer of the soil. The method is environmentally friendly and pollution-free, and the crop stalks are fully utilized, thereby reducing the cost of repairing the soil.

The invention relates to a contaminated soil remediation method. The contaminated soil remediation method is characterized by including steps of 1) preparing straws, cornstalks and peanut branches and proportioning according to the mass ratio of 3:4:1; 2) stirring and smashing the proportioned raw materials in a smasher for 10-15 min until size of smashed particles is 10mm; 3) adding 50% of water in total weight for mixing; 4) dressing mixture into the soil, fertilizing, irrigating and adding quick lime to adjust pH of the soil at 7-8, so that contaminants in the soil can be degraded on the upper layer of the soil aerobiotically.
Description
technical field [0001] The invention relates to a soil remediation method, in particular to a polluted soil remediation method, and belongs to the technical field of soil remediation. 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. [0003] With the development of industry and the continuous improvement of living standards, human beings pollute the soil more and more seriously. Soil pollution has become a global problem. All c...
