Embodiment Construction

[0013] In order to further illustrate the present invention, the present invention will be further described in detail below in conjunction with preferred embodiments. A combined restoration method for arsenic-containing organic matter pollution in soil, which is composed of a microwave restoration system, a chemical oxidation system and a phytoremediation system. The specific steps are as follows:

[0014] Step 1): Investigate the soil pollution zone, determine the location and area of ​​the polluted area, detect the content and type of organic matter in the soil; obtain the geological conditions of the soil and groundwater, and determine the pollution situation;

[0015] Step 2): Establish a microwave remediation system above the determined soil pollution zone, lay microwave absorbing materials in the soil, and bury several temperature sensors; turn on the microwave generator, be heated by the microwave heating device, and irradiated by the radiator On the soil surface, the ...

Abstract

The invention belongs to the technical field of environmental protection, and particularly to a soil arsenic-containing organic compound pollution combined repair method, which uses a microwave repairsystem, a chemical oxidation system and a plant repair system, wherein the microwave repair system heats soil to be repaired, the gases generated by volatile organic compounds are collected, an oxidant is injected into the soil, the arsenic-containing organic compounds are subjected to a microwave-catalyzed oxidation reaction so as to degrade the organic compounds, and enrichment is performed byplanting a super-enriching plant pteris vittata l, wherein the microwave repair system and the plant repair system are intermittently and alternately performed. According to the present invention, thesoil is repaired by combining and intermittently and alternately performing the microwave repair, the chemical oxidation and plant repair, such that the arsenic-containing organic compounds in the soil can be subjected to effective deep-treatment.

Description

technical field [0001] The invention belongs to the technical field of soil remediation, and in particular relates to a method for combined remediation of soil arsenic-containing organic matter pollution. Background technique [0002] At present, the overall situation of soil pollution in my country is quite severe. One is serious soil pollution, and the other is huge harm of soil pollution. Soil organic pollution refers to the soil pollution caused by the organic matter entering the soil exceeding the self-purification capacity of the soil. The soil environment is one of the basic elements of the ecosystem and the basis for the survival and development of human beings and organisms. The soil environment not only directly affects the development of the national economy and the safety of land resources and the environment, but also affects the safety of agricultural products and human health. Contents of the invention [0003] The present invention provides a method for j...
