Embodiment 1

[0095] Example 1 For the treatment of general organic matter polluted soil

[0096] In this embodiment 1, the electrocatalytic water device 1 is used to control soil pollution. specifically, Figure 1-3 The electrocatalytic water device 1 is shown. The electrocatalytic water device 1 includes a group of two electrocatalytic units 11 and 12 stacked in parallel from bottom to top. sequentially connected.

[0097] Among them, according to Figure 4-5 As shown, each of the electrocatalytic units 11 and 12 includes: an electrolysis pipeline 13 and an insulating pipeline 14 . A closed cavity 131 is formed in the electrolysis pipe 13 . In the actual use process, the airtight cavities of each electrocatalytic unit are connected to each other through connecting water pipes, so that the water coming in from the water inlet can flow through each electrocatalytic unit in turn, thereby improving the catalytic efficiency of water molecules and ensuring water Full electrolysis of molecu...

Embodiment 2

[0118] Example 2 Treatment for severely polluted soil with organic matter

[0119] The structure of the electrocatalytic water equipment 2 adopted in this embodiment 2 has many similarities with the electrocatalytic water equipment 1 of the embodiment 1. 1 differs in that, as Figure 11-12 As shown, the electrocatalytic water device 2 includes a group of three electrocatalytic units 21 , 22 , 23 stacked in parallel from bottom to top.

[0120] Wherein, the water inlet 25 is arranged on the end of the first electrocatalytic unit 21 away from the electrode column, and the two water outlets 26 and the other water outlet 27 are all arranged on the third electrocatalytic unit 23 near the electrode column. one end.

[0121] In addition, the two water outlets 26 and the other water outlet 27 are located at the end of the electrocatalytic water device 2 away from the water inlet 25 .

[0122] A method for treating soil pollution, which includes the following steps: electrocatalytic w...

Embodiment 3

[0127] Example 3 Treatment of soil polluted by heavy metals

[0128] The electrocatalytic water equipment used in this example is the electromagnetic water treatment device disclosed in Example 1 of CN201310129563.6.

[0129] A method for controlling soil pollution, comprising the following steps: dissolving electrocatalytic water produced by an electrocatalytic water device in a volume of 1-3m 3 The flow rate of / h is irrigated to the soil polluted by heavy metals, so that the oil in the soil and the electrocatalytic water are mixed into sewage, and then the water is pumped and recycled. Relying on the decomposition, catalytic effect and redox effect of electrocatalytic water, the polluted soil is treated7 days; Among them, the amount of electrocatalytic water is 5 times that of polluted soil; the pH value of electrocatalytic water is 7-8.5; the oxidation-reduction potential is below -100mV.

[0130] The schematic flow sheet of soil pollution control method is the same as th...

Abstract

The invention discloses application of electro-catalysis water equipment to soil pollution treatment and a soil pollution treatment method. When the provided soil pollution treatment method is adopted for treating soil pollution, the treating efficiency is high, and sodium chloride, potassium chloride, calcium chloride and other salt do not need to be added in water; the treatment speed is high, high-reducibility electro-catalysis water is used for irrigating the land or spraying plants in a normal state or periodical manner, the purpose of maintaining the land can be achieved, the pH value of soil is increased, the Eh value of the soil is reduced, meanwhile, VOCs is decomposed, heavy metal is treated, and germs are killed out; the treatment method is suitable for various different pollution kinds, different pollution grades and even complex pollution; it is guaranteed that the problem that secondary pollution is left in the soil is solved after treatment; and the treatment economic cost is low and is easily affordable for clients.

Description

technical field [0001] The invention relates to the application of electrocatalytic water equipment in controlling soil pollution and a soil pollution treatment method. Background technique [0002] People's agricultural, industrial and mining activities have made soil pollution more and more serious. Soil pollution can be divided into: 1. Organic pollution: petroleum, organic pesticides, etc.; 2. Inorganic pollution: heavy metal pollution, etc.; 3. Biological pollution: bacteria, fungi, etc. . The above-mentioned various pollutants will be degraded in the natural state, such as the migration and degradation of chemical pesticides in the soil, and the migration and transformation of heavy metal elements and chemical fertilizers in the soil. However, these degradation effects are limited after all, and it is impossible to fundamentally control the problem of soil pollution. [0003] The current technologies for controlling various types of pollution are as follows: [0004...
