Abstract
The utility model discloses an oil filed inorganic salt pollution soil remediation structure, which belongs to the field of soil remediation and comprises a pollution soil layer, blind holes and a fertilizer layer. More than two rows of blind holes are arranged on the pollution soil layer, the number of each row of the blind holds is larger than two, and halophyte is arranged in the blind holes. The fertilizer layer is positioned below the soil layer, the thickness of the pollution soil layer is 10cm to 60cm, and the height of each blind hole is 1cm to 2cm, the line spacing of adjacent blind holes is 30cm to 40cm, and the central distance between adjacent rows of the blind holes is 15cm to 25cm. When the oil filed inorganic salt pollution soil remediation structure is used for remediate of oil filed inorganic salt pollution soil, plant remediate can be achieved on site without transportation. Thus, oil filed inorganic salt pollution soil remediation structure is little in investment, low in cost, free of secondary pollution and good in salt removal effect.
Description
Technical field
The utility model relates to the soil remediation field, particularly a kind of oil field mineral salt contaminated soil repair structure.
Background technology
The a lot of onshore oil fields of China are the oil field of northern area especially; In oil exploration, recovery process, can produce saliferous mud, deep layer landwaste; The material severe contaminations such as additive that inject in saliferous mud, deep layer landwaste and the exploration recovery process soil around the well site; Make well site many farmlands salt content severe overweight on every side, cause agricultural land soil generation secondary salinization around the well site.
At present, the method for improvement secondary salinization soil has physically improved method, chemical amendments and biological modification method three major types.Wherein, physically improved method has the zanjon drainage, the washing salinity by irrigation method, and the sth. made by twisting method is enclosed on the level land; Chemical amendments is on salinized soil, to use the salt alkali content that chemical agent reduces soil, improves the structure and the permeability of soil; The biological modification method is plantation plant or a microbe inoculation on contaminated soil, utilizes the interaction between plant, microorganism and the environment, and the environmental pollution material is removed, decomposes, absorbed or adsorbs, and makes soil environment be able to the method for recovering again.
In the process that realizes the utility model, the inventor finds that there is following problem at least in prior art:
Though more than physically improved method and chemical amendments have certain improved effect; But there is bigger side effect, bigger like the construction investment cost, need utilize the freshwater resources desalinization of soil by flooding or leaching; The Northwest at drought and water shortage; Be difficult to promote the use of, and in case after stopping using the freshwater resources desalinization of soil by flooding or leaching, soil salt content also can return to concentration in the past.The biological restoration method has certain limitation, and existing also do not have a kind of repairing polluted soil structure that is applicable to exist.
The utility model content
The utility model provides a kind of salt content that can reduce soil in order to solve the deficiency that exists in the prior art, thoroughly the oil field mineral salt contaminated soil repair structure of repairing polluted soil.
The utility model solves the technical scheme that its technical problem adopted:
A kind of oil field mineral salt contaminated soil repair structure comprises the contaminated soil layer, and said contaminated soil layer is provided with the above blind hole of two row, and the blind hole of every row is more than two, is provided with halophytes in the said blind hole.
Said contaminated soil layer has the fertilizer layer.
The thickness of said contaminated soil layer is 10-60cm.
The height of said blind hole is 1-2cm.
Wherein, the line space of each adjacent blind hole is 30-40cm.
Wherein, in every row, the centre-to-centre spacing of adjacent blind hole is 15-25cm.
The setting of said contaminated soil layer in the enclosure.
The beneficial effect of the technical scheme that the utility model embodiment provides is: the contaminated soil repair structure of the utility model embodiment is when repairing oil field mineral salt contaminated soil; On carrying can be in position, carry out phytoremediation; Small investment; Cost is low, non-secondary pollution, and the salt removal effect is better.Add the fertilizer layer and more help the halophytes survival, grow up, adopt the structure of the utility model to improve contaminated soil year by year, its salt content is reduced.
Description of drawings
Fig. 1 is the contaminated soil repair structure figure that the utility model embodiment provides;
Fig. 2 is the vertical view of Fig. 1;
Fig. 3 is the another kind of contaminated soil repair structure figure that the utility model embodiment provides.
In the accompanying drawing:
1. contaminated soil layer, 2. fertilizer layer, 3. halophytes, 4. blind hole, 5 shells.
Embodiment
For the purpose, technical scheme and the advantage that make the utility model is clearer, will combine accompanying drawing that the utility model embodiment is done to describe in detail further below.
Referring to Fig. 1, a kind of oil field mineral salt contaminated soil repair structure comprises contaminated soil layer 1, and contaminated soil layer 1 is provided with the above blind hole 4 of two row, and the blind hole 4 of every row is more than two, is provided with halophytes 3 in the blind hole 4.
The utility model embodiment is provided with halophytes through on contaminated soil layer 1, blind hole being set in blind hole, come to reduce year by year the salt content of soil in the contaminated soil layer through halophytes, reaches the effect of thorough repairing polluted soil.The halophytes of the utility model embodiment is selected Suaeda salsa for use.
Referring to Fig. 1, contaminated soil layer 1 has fertilizer layer 2.
Referring to Fig. 1 and Fig. 2, better grow in order to make halophytes, reach better repairing effect, the thickness c of contaminated soil layer 1 is 10-60cm.Halophytes 3 is provided with more than two row, and the line-spacing a of adjacent halophytes 3 is 30-40cm.The spacing in the rows b of every capable halophytes is 15-25cm.The height h of blind hole 4 is 1-2cm.
The method that makes up the contaminated soil repair structure of the utility model is:
(1) plough deeply contaminated soil, the chemical fertilizer of spreading manuer in holes forms the chemical fertilizer layer, on the fertilizer layer, lays the contaminated soil layer of 10-60cm then.
(2) in contaminated soil layer 1, adopt the mode of drilling or program request to plant the Suaeda salsa seed; Can adopt the mode of program request; Lateral separation 30-40cm is provided with a blind hole in the contaminated soil layer, and longitudinal separation 15-25cm is provided with a blind hole, and the degree of depth of blind hole is 1-2cm; In blind hole, place the Suaeda salsa seed then, with contaminated soil the Suaeda salsa seed is covered at last.
The utility model embodiment is convenient to carry out at the experiment booth reparation observation of contaminated soil, and the contaminated soil repair structure has good effect in order to repair oil field mineral salt contaminated soil, and the clearance of salt can reach more than 90%.
Referring to Fig. 3, also can contaminated soil layer 1 be arranged in the shell 5 plantation halophytes 3 in the blind hole 4 of contaminated soil layer 1.
