Problems solved by technology

[0002] The soil is originally a natural shelter and purification treatment site for various wastes. The soil accepts pollutants, which does not mean that the soil is polluted. Only when the soil contains too many pollutants, it affects and exceeds the self-purification ability of the soil. , thus having a harmful effect on hygiene and epidemiology, it shows that the soil has been polluted. There are many reasons for soil pollution, such as industrial sludge, garbage for agriculture, sewage irrigation, and the deposition of pollutants in the atmosphere. Mineral chemical fertilizers and pesticides containing heavy metals, etc., nearly one-fifth of China's existing cultivated land is polluted to varying degrees. Polluted soil will lead to crop yield reduction, and may even cause excessive pollutants in agricultural products, which will endanger human health
[0003] At present, contaminated sites and soil remediation technologies include physical, chemical and biological remediation. However, most of the existing remediation methods have a narrow range of application due to their high cost and cannot meet the needs of a large number of heavily polluted sites. Existing With advanced physical separation and repair technology, a large amount of dust cannot be discharged, resulting in polluted air, which has a certain impact on the physical and mental health of the staff

Embodiment 1

[0055] see Figure 1-5 , the present invention provides a technical solution:

[0056] A soil restoration method, comprising the following steps: 1) closing all discharge valves, opening a feed valve, pouring soil from a feed port 2, and entering the soil separation and repair box 1;

[0057] 2) Turn on the first vibrating motor 9 and the second vibrating motor 17, the soil at the top of the second layer of filter screen 4 starts to be screened, fine sand and drill particles fall into the top of the third layer of filter screen 14, and the third layer of filter screen 14 Carry out screening again, drill particle falls into the top of discharge plate 16;

[0058] 3) In the process of soil screening, the fan 23 inside the dust pipe 21 absorbs the soil dust into the dust filter box 24, the water inlet pipe 25 is connected to the external water pipe, and the small nozzle 27 starts to spray the dust in the dust filter box 24, and the dust filter box 24 is opened. Water outlet val...

Embodiment 2

[0062] On the basis of embodiment 1, in step 2) the soil treatment capacity of the second layer of filter net is calculated according to the following method:

[0063]

[0064] Among them, Q is the amount of soil treatment, t / h;

[0065] is the effective screening area coefficient of the filter, and its range is 0.8 to 0.9;

[0066] α is the degree of looseness of the soil, t / m 3 ;

[0067] F is the nominal area of ​​the screen of the filter, m 2 ;

[0068] V is the average volume handling capacity per unit screening area of ​​the filter, m 3 / (m 2 h);

[0069] K 1 is the influence coefficient of fine particles in the soil;

[0070] K 2 is the influence coefficient of coarse particles in the soil;

[0071] K 3 is the screening efficiency coefficient;

[0072] K 4 is the particle shape coefficient of the soil;

[0073] K 5 is the influence coefficient of soil moisture;

[0074] K 6 is the influence coefficient of the screening method;

[0075] K 7 is the...

Abstract

The invention discloses a soil restoration method. When soil enters a soil separation and restoration box, a feed valve is switched off, a first vibrating motor and a second vibrating motor are started, the soil on the top of a second layer of filter net starts to be screened, fine sand and small shots fall to the top of a third layer of filter net to be screened by the third layer of filter net again, and the small shots fall to the top of a discharge plate. By means of the method, the soil can be rapidly separated and restored, and the working efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of soil restoration, in particular to a soil restoration method. Background technique [0002] The soil is originally a natural shelter and purification treatment place for various wastes. The soil accepts pollutants, which does not mean that the soil is polluted. Only when the soil contains too many pollutants, it affects and exceeds the self-purification ability of the soil. , thus having harmful effects on hygiene and epidemiology, it shows that the soil has been polluted. There are many reasons for soil pollution, such as industrial sludge, garbage for agriculture, sewage irrigation, and pollutant deposition in the atmosphere. Mineral chemical fertilizers and pesticides containing heavy metals, etc., nearly one-fifth of China's existing cultivated land is polluted to varying degrees. Polluted soil will lead to crop yield reduction, and may even cause excessive pollutants in agricultural products, which i...
