Soil bioremediation method

Abstract

The invention discloses a soil bioremediation method. The method comprises the following steps: S1, investigating and analyzing the condition of polluted soil on site; s2, biological fertilizer is scattered on the surface of the soil, and then the polluted soil is turned over through a rotary cultivator; s3, blending a mixing agent, and uniformly dispersing the mixing agent on the surface of the ploughed soil; s4, the polluted soil is turned over and leveled through the rotary cultivator again; s5, digging holes in the surface of the soil, putting earthworms into the holes, and backfilling; s6, spraying water to the soil; s7, a sunshade net is laid on the surface of the soil, and then spraying and watering are conducted again; and S8, after every 30-60 days, the sunshade net is opened, then the mixing agent is sprayed again, the soil is ploughed and leveled, finally, the sunshade net is laid, and mist and water are sprayed till remediation is completed. The soil bioremediation method relates to the technical field of environmental protection, the remediation process of the soil bioremediation method does not cause damage and pollution to the natural environment, the concept of soil environment-friendly remediation is met, and high sustainable development is achieved.

Description

technical field [0001] The invention relates to the technical field of environmental protection, in particular to a soil bioremediation method. Background technique [0002] my country's agricultural land is forced to pursue a high yield per mu, and a large amount of chemical fertilizers and pesticides are used. The soil is seriously polluted, not only the pesticide residues and harmful metals exceed the standard, the soil is compacted, the soil pores are blocked, the water permeability and air permeability of the soil are affected, and the nutrients enter the soil solution from the soil particles, so that the soil fertility is reduced and the organic matter is missing. Inherited diseases are ubiquitous; the crops cultivated by such soil will inevitably be seriously polluted, endangering food safety and the health of the broad masses of the people. [0003] At present, soil remediation methods mainly include physical remediation, chemical remediation, and biological remedia...
