Embodiment Construction

[0041] The U.S. Environmental Protection Agency refers to solidification and stabilization technology as the best technology for treating harmful and toxic wastes. The present invention continues the treatment concept of solidification and stabilization, and introduces advanced micro-nano bubble water and microbial stabilization technologies.

[0042] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0043] Such as Figure 1-Figure 5 As shown, the micro-nano bubble fixation-microbial stabilization repair method for soil pollution includes the following steps:

[0044] Step 1: Use physical-chemical methods to solidify the heavy metal ions in the soil to prevent the migration and diffusion of heavy metals;

[0045] Step 2: Use microbial methods to absorb and transform to reduce the leaching content of pollutants in the soil.

[0046] Further, the method of solidifying the heavy metal ions present in the soil ...

Abstract

The invention provides a micro-nano bubble immobilization-microorganism stable remediation method for soil pollution. The method comprises the following steps that 1, heavy metal ions existing in soilare immobilized through a physical-chemical method so as to prevent migration and diffusion of heavy metal; and 2, the heavy metal is absorbed and converted by using a microorganism method to reducethe leaching content of pollutants in the soil. Thus, the method can effectively overcome the defects that conventional soil remediation methods employing immobilization and stabilization treat both symptoms instead of root causes, only the existing form of heavy metal is changed and heavy metal elements are easily activated again in soil to generate secondary pollution.

Description

technical field [0001] The invention relates to the technical field of soil stabilization and repair, and also to the technical field of micro-nano bubble fixation-microbial stabilization repair, in particular to a micro-nano bubble fixation-microbe stabilization repair method for soil pollution. Background technique [0002] Soil refers to a layer of loose material on the surface of the earth, which is composed of various granular minerals, organic matter, water, air, microorganisms, etc., and can grow plants. Soil is composed of minerals from weathering of rocks, animals and plants, organic matter produced by the decomposition of microbial residues, soil organisms (solid phase substances), water (liquid phase substances), air (gas phase substances), oxidized humus, etc. Heavy metal pollution in soil mainly comes from atmospheric deposition of pollutants, sewage irrigation, application of agricultural materials, and solid waste stacking. The remediation technologies for so...
