Method for soil remediation through electric power method

Abstract

The invention provides a method for soil remediation through an electric power method. The method for soil remediation through the electric power method comprises the following steps that 1, the periphery of to-be-remediated soil is plugged; 2, an electrode is inserted into the to-be-remediated soil; 3, water is discharged, wherein the water discharge amount is 8-15 kg per square meter of the soil; and 4, the electrode is electrified, wherein the voltage is 110-220 V, and the electrifying time is 3-6 hours. The method has the advantages that the soil remediation effect is good, and the secondary pollution can be effectively avoided.

Description

Technical field: [0001] The invention relates to a method for repairing soil by an electrodynamic method, and belongs to the technical field of soil repair. Background technique: [0002] Nearly one-fifth of China's existing arable land is polluted to varying degrees. Polluted soil will lead to crop yield reduction, and may even cause pollutants in agricultural products to exceed the standard, thereby endangering human health. In addition, with the acceleration of economic development and urbanization, the site pollution caused by industrial and mining enterprises is also very serious. Due to the changes and adjustments in the industrial structure and urban layout, some polluting enterprises such as chemical industry and metallurgy have relocated one after another, and some enterprises have closed down, resulting in continuous generation of polluted sites. Soil is an important material basis for human social production activities and an indispensable natural resource that i...

Problems solved by technology

[0003] With people's attention to environmental issues and the advancement of modern agriculture, pesticide microbial remediation technology will play a greater role in the control of pesticide environmental pollution, but there are also the following problems in the remediation process: Microbial remediation research has achieved a lot in the laboratory However, when the results are applied to soil pollution sites, they often fail to achieve the expected results, and even contradict the laboratory results; during the test, microorganisms are greatly affected by the outside world; in many cases, the pollutants cannot be completely degraded, and may Produces intermediates that are sometimes more toxic than the parent compound
