Embodiment 1

[0021] A kind of technology that is used to control dichloroether pollution in soil, specifically:

[0022] Add 25g of ferrous sulfate and 5g of elemental iron to 1000g of contaminated soil containing dichloroethyl ether 20mg / kg and mix well, add 36g of hydrogen peroxide (27.5% aqueous solution) to the well-mixed contaminated soil and maintain it for 78 hours, continue After adding 25g of calcium oxide and 50g of cement and curing for 36 hours, it can be sampled and tested.

[0023]

Embodiment 2

[0025] A kind of technology that is used to control dichloroether pollution in soil, specifically:

[0026] Add 20g of ferrous sulfate and 10g of elemental iron to 2000g of contaminated soil containing dichloroethyl ether 20mg / kg and mix well, add 100g of sodium peroxide to the uniformly mixed contaminated soil and maintain it for 24 hours, then continue to add 200g of calcium carbonate and 20g of silica can be sampled and tested after curing for 18 hours.

Embodiment 3

[0028] A kind of technology that is used to control dichloroether pollution in soil, specifically:

[0029] Add 10g of ferrous sulfate and 0.1g of elemental iron to 1000g of polluted soil containing dichloroethyl ether 20mg / kg and mix uniformly, pass 50g of ozone into the uniformly mixed polluted soil and maintain it for 78 hours, then continue to add 10g of calcium oxide and 100g of cement can be sampled and tested after curing for 24 hours.

Abstract

The invention belongs to the field of soil pollution treatment and particularly relates to a process for treating dichloroethyl ether pollution in soil. After the process disclosed by the invention is adopted, dichloroethyl ether in the soil can be effectively degraded, so that content of the dichloroethyl ether in the soil is obviously reduced. According to the invention, raw materials are rich and are low in price; the process is simple; and the process is easy for implementing large-scale production and is suitable for large-area popularization and application.

Description

[0001] technical field [0002] The invention belongs to the field of soil pollution control, in particular, the invention relates to a process for controlling dichloroethyl ether pollution in soil. Background technique [0003] At present, soil pollution in our country is becoming more and more serious, which not only destroys the ecological system of the soil itself, directly or indirectly endangers human health, but also forms cross-media pollution, especially posing a threat to groundwater resources and causing serious consequences. Engineering Restoration Technology. [0004] Soil remediation technology can be divided into physical remediation, chemical remediation and biological remediation. The invention adopts the combined technology of chemical restoration and physical restoration to degrade and solidify the dichloroethyl ether in the polluted soil to achieve the expected removal effect. Contents of the invention [0005] The purpose of the invention is t...
