Description
Technical field
The present invention relates to contaminated soil Treatment process fields, and in particular to a kind of side of restoring soil with serious petroleum pollution
Method.
Background technology
With the rapid development of petroleum industry, the exploitation of oil, smelting, the pollution of transportational process and omits accident and contain
After the discharge etc. of oily waste water causes soil contamination problem, oil to enter soil, soil texture can be destroyed.Influence the penetrating of soil
Property, soil quality is reduced, greasy dirt adheres on root system of plant, forms one layer of mucous membrane, hinders root system of plant to nutrient and moisture
Absorb, cause root system rot, influence the growth of crops, if the soil of oil pollution without repairing in time, outdoor exposure
Solution gas can be volatized into air in oil-polluted soils, cause atmosphere pollution, the soil of oil pollution that can flow into water with rainwater
Cause water pollution in domain.For above-mentioned oil-polluted soils recovery technique include peripheral doses, chemical remediation in existing technology
With it is biological prosthetic, peripheral doses and chemical remediation can cause secondary pollution during remedying oil-polluted soils, change soil
Structure and of high cost has certain limitation, the biological prosthetic research hotspot become in recent years, due to severe stone application is upper
The oil content of soil contaminated by crude oil is big, and toxicity is big, the repair ability of microorganism or plant is restricted, when soil serious pollution,
Microorganism in soil is difficult to survive, and biological renovation method is difficult to effectively implement, therefore the present invention proposes based on biotechnology
Combined remediation method soil with serious petroleum pollution is effectively repaired.
Invention content
The purpose of the invention is to overcome the problems of the prior art, a kind of restoring soil with serious petroleum pollution is provided
Method.
The present invention provides a kind of methods of restoring soil with serious petroleum pollution, include the following steps：S1, to severe oil
The plot of pollution applies surfactant, and the amount of applying of surfactant is 60-100g/m2, soil standing is after 2-3 days by oil-containing
Topsoil of the amount more than 20wt% roots out accumulation, and animal wastes, agricultural crop straw, swelling are then added into the topsoil of accumulation
Soil, urea and the first oil degradation bacteria ferment, and fermentation obtains tunning after 50-120 days；
S2, it the plot after topsoil will be rooted out turns over, ploughed depth 25-40cm, water spray keeps soil wet after turning over
Degree reaches 50-65%, and adjusts P in soil h to 7-10, then adds the second oil degradation bacteria, and the plot plantation after turning over
Alfalfa is added in the fermentation heap of step S1 after preceding 2-3 batches of alfalfa harvesting and ferments；
S3, the tunning of step S1 is granulated in comminutor organic fertilizer is made, organic fertilizer is with 20-30kg per acre
Dosage apply in Alfalfa Growing area.
Preferably, the first oil degradation bacteria is bacillus subtilis and white-rot fungi according to 1:1 is configured to 8 × 1010A/ml
