Description

A kind of microorganism in situ restorative procedure of oil-polluted soils
Technical field
The invention belongs to oil-polluted soils and administer field, relate to microorganism in situ reparation, especially a kind of microorganism in situ restorative procedure of oil-polluted soils.
Background technology
Soil pollution is apparently higher than original content of soil, to surpass the self-purification capacity of soil because mankind's activity causes the content of some harmful components, cause that thus composition of the soil, 26S Proteasome Structure and Function change, harmful substance or its catabolite be accumulation gradually in soil, reaches the degree being detrimental to health.Oil-polluted soils results from many links such as oil exploration, exploitation, transportation, storage, processing, accidental leakage, is the discarded object that petroleum industry produces.Oily sludge contains the poisonous and harmful substances such as macromolecule organic, if do not carry out, does not effectively properly dispose, and can cause the severe contamination of soil, underground water, water system and ocean, and health is worked the mischief and affected.
More than totally 400 of the oil gas field of China's exploration, exploitation, is distributed in 25 provinces,municipalities and autonomous regions in the whole nation, nearly 200,000 square kilometres of field area working range.According to incompletely statistics, there are more than 20 ten thousand places in internal contamination place, field area, and high concentration petroleum pollution soil and oil sediment burden exceed 2,000,000 tons.North China Oilfield a lot of farmlands around cannot be cultivated due to crude oil pollution, all will pay substantial contribution as the reparation to peasant every year; Yellow River System annual oil-containing reaches as high as 4.82mg/L, and Liaohe River water system annual oil-containing reaches as high as 7.68mg/L, has surpassed significantly the standard (< 0.1mg/L) of three grades of surface water of country; Some areas even pollute groundwater resources, as more than the In Zibo, Shandong the highest oil-containing of underground water reached 100mg/L, surpass national standard (< 0.1mg/L) more than 1000 times.
Restriction due to conditions such as cost, technology, the oil-polluted soils of each elephant or put together is deposited, but after depositing, conventionally do not do further processing or carry out on a small scale but the higher technical finesse of cost, for example: partition method, chemistry stir partition method, heat is washed method, pyrolysis processing method, spiral grate incinerator method, organic solvent extractionprocess, prefabricated bed method, bioreactor method etc. from revolving in ultrasonic radiation.These method great majority belong to showering method, need to move contaminated soil and focus on, not only with high costs, treating capacity is limited, and easily causes secondary pollution.
Microorganism in situ recovery technique refers to the biological control measure that utilizes specific microorganism absorption, conversion, removing or degraded soil petroleum pollution thing to realize soil sanitation.This technology can make petroleum pollution remove from soil, less to surrounding environment influence, can not produce secondary pollution, the huge soil remediation potentiality that have.But the microorganism recovery technique of existing oil-polluted soils has some limitations, as microorganism is repaired, the duration is long, effect is thorough, be not suitable for the reparation of severe contamination soil etc.
Large quantity research shows, a principal element of restriction oil-polluted soils microorganism in situ recovery technique development is that contaminated soil lacks enough oxygen and nutrition conventionally for the microorganism Fast Growth of degraded oil, so that the improvement potentiality that these microorganisms possess self are not in full use, and fail to become comparatively desirable soil petroleum pollution control measures.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art part, a kind of microorganism in situ restorative procedure Soil Microorganism Fast Growth and the oil-polluted soils that degradation rate is very high that promotes is provided, utilize hydrocarbon degradation bacterium to carry out the repair process of oil-polluted soils, hydrocarbons in soil (sump oil) is resolved into carbon dioxide and water, reach the object of eliminating oil pollution.

Simulated experiment:
In laboratory, utilize the sump oil contaminated soil of simulation preparation to carry out test, soil sample is taken from untainted the earth soil sample, and crude oil is taken from the aging crude oil after dehydration, substantially not moisture after tested.Its process for preparation is: first, from obtaining the earth air-dry, put into the plastic big basin that diameter is about 90cm, the degree of depth is about 25cm, claims the weight of its soil.Then according to the percentage of soil weight, add the crude oil (45 ℃ of left and right of crude oil temperature) after dehydration, be uniformly mixed the sump oil contaminated soil that forms simulation.The indoor factorial experiments analysis of having carried out respectively the evaluation test for the treatment of effect and having affected treatment effect.The oil content of test requirements document soil is below 15%.The simulating pollution soil that is 5% and 15% to oil content has respectively carried out test evaluation research.
(1) when soil oil content is 5%, degrade after one month, the oil content in soil can reach (1.9%) below 2%; After two months, the oil content in soil can drop to below 0.7%; After three months, the oil content in soil can drop to (0.18%) below 0.3%, has reached pollutant control criterion GB4284-84 mineral oil in fluid content's index in national agricultural mud.
(2) when soil oil content is 15%, degrade after one month, the oil content in soil is below 7%; After two months, the oil content in soil is that after 5.5%, four month, the oil content in soil reaches below 2%.
Site test:
According to the analysis result of the present situation of Daqing oil field crude oil pollution and improvement, respectively three kinds of dissimilar solid-state oily wastes have been carried out to three kinds of dissimilar biological prosthetic experimental studies.The biological prosthetic test of the first type is to take the biological prosthetic test of the oil-containing soil that well site that oil well operation pollutes is main body; The biological prosthetic test of the second type is to take the biological prosthetic test that the oily sludge removed in various container handlings and equipment in multi-purpose station is main body; The biological prosthetic test of the third type is to take the biological prosthetic test that the oily sludge of sedimentation is main body in the earth storage of ground crude oil recycling point.
By the field trial under the climatic environment condition of Daqing Area to three kinds of dissimilar solid oily wastes of oil field existence at present, take and process the treatment effect that measurement index that the oil content in rear solid waste is treatment effect is evaluated these two kinds of microorganism formulations, can draw the following conclusions:
(1) adopting this patent product is feasible to the biological prosthetic of oil contaminated soil, and the oil content of the oily sludge after processing can be controlled in national agricultural soil safety standard (0.3%).But when operation, consider the recycling of adaptability and the resource of microbe inoculation, initial oil content should be controlled at 15%(W/W) in.
(2), in whole process of the test, how making microniological proudcts and crude oil in contaminated soil fully contact is the key that assurance obtains good test effect, therefore, suggestion promote in the application machine method of mixing, guarantee the microorganism of inoculation and contacting of crude oil.
(3) by having experienced the biodegradation test effect analysis of 2 years, as the sump oil hole of oil extraction No.1 Factory, the recover the oil tracking and testing analytical test of each junior unit in the apricot 6-J2-104 well of four factories and apricot 2-40-620 well, while suspending test in by the end of October, 2010 in, oil content is respectively 27.1%, 3.8% and 7.97%, but when test in August, 2011, find that oil content is respectively 5.23%, 1.07% and 1.21%, by the follow-up sudden and violent oxygen of turning over, to in September, 2011, oil content is respectively 0.97%, 0.07% and 0.09%.Illustrate: the microorganism in Daqing Area severe cold winter still can survive, and again plays a role when temperature is suitable.
