System and method for aeration remediation of soil polluted with organic pollutants

Abstract

The invention relates to a system and a method for aeration remediation of soil polluted with organic pollutants. The system comprises a plurality of aeration pipes, a plurality of air exhaust pipes,at least one adsorption pad placed in every aeration pipe, a plurality of aeration holes arranged at every aeration pipe and a plurality of air exhaust holes arranged at every air exhaust pipe; when the number of the adsorption pads is more than one, the plurality of adsorption pads are arranged at intervals in a layered mode in the length direction of the corresponding aeration pipe; the aerationpipes and the air exhaust pipes are inserted into soil at intervals, air is injected into the aeration pipes, and the air in the aeration pipes can transport an adsorbent on the adsorption pads intothe soil; microbial strains are arranged on the upper surfaces of the aeration pipes and the air exhaust pipes, and the aeration pipes can supplement oxygen to soil; and the aeration pipes and the plurality of adjacent air exhaust pipes can form air phase circulation.

Description

technical field [0001] The invention relates to a repair system, in particular to a gas injection repair system and a repair method for soil organic pollutants. Background technique [0002] Soil is an important natural resource for human survival and agricultural production. Due to the characteristics of strong toxicity and easy enrichment of heavy metals, the pollution of heavy metals to soil is difficult to recover in a short period of time. The soil in some areas is polluted by heavy metals. The heavy metal content of the crops growing on it exceeds the standard, resulting in increasingly serious soil environmental pollution and affecting human health. [0003] The current solution to soil remediation methods not only wastes manpower and material resources, but also has poor repair effects, and easily causes secondary pollution of the soil. When performing wetland restoration, drilling operations are required for each repair, which is time-consuming and laborious. The b...

AI Technical Summary

Problems solved by technology

[0003] The current solution to soil remediation methods not only wastes manpower and material resources, but the repair effect is not good, and it is easy to cause secondary pollution of the soil. When performing wetland restoration, drilling operations are required for each restoration, which is time-consuming and laborious, and the restoration is not through. The bioremediation method is easy to cause the accumulation of soil pollution elements, the vitality of the soil is reduced, and the practicability is not strong
