Description
Technical field:
The present invention relates to the remedying oil-polluted phreatic method of a kind of contaminated phreatic improvement method, especially original position.
Background technology:
Accident that leaks in oil production, accumulating and the refining process and subsurface storage jar leak, and cause petroleum pollution to get into underground water through aeration zone, have a strong impact on phreatic quality safety.Oil is mainly with three kinds of form polluted underground waters: The dissolved, ADSORPTION STATE and remaining liquid.Because petroleum component is complicated, the toxicity of various components is also inequality.Modal be have high relatively solubleness, transfer ability and three causes toxic pollutent, like BTEX etc.The not only direct polluted underground water of this pollutant, and can enlarge pollution range with phreatic flowing transport diffusion.Reparation of groundwater pollution dystopy and the development of monitoring nature decay technique have become relative proven technique type so far; But it is imperfect yet in some defectives that application process occurs; Research is strengthened the nature damped system and can be remedied and administer length consuming time and the huge shortcoming of rehabilitation expense, and using it, to repair underground water petroleum pollution significant to controlling migration, the purifying polluted underground water of pollutent in underground environment.
Underground water biology in situ recovery technique is because its remediation efficiency is high and to advantages such as the disturbance of surrounding environment are little, paid close attention to by people.Mainly comprise:
Phytoremediation technology utilizes the plant in treating contaminate environment to show that mainly plant promotes the biological degradation of pollutent and strengthens the aspects such as mineralization of rhizospheric microorganism the direct absorption of pollutent, various secretory product or the enzyme that plant discharged.In generally being suitable for administering, the petroleum pollution of lower concentration soil.Cheng Guoling, Li Peijun " plant of oil-polluted soils and mikrobe recovery technique " " environmental engineering journal ", 2007, (06): 91-96.
The mikrobe recovery technique comprises bacterium method, biological culture method and the soil cultivating method etc. of throwing.Throwing the bacterium method is contaminant degradation bacterium from external source to oil-polluted soils that directly insert, and necessary grand nutrition element of these bacterial growths and micronutrient element are provided simultaneously.The biological culture method is regularly in contaminated soil, to add nutrition, oxygen or H
2O
2As the electron acceptor(EA) of microbiological oxidation, improve the metabolic activity of indigenous microorganism, contaminant degradation is CO the most at last
2And H
2O.The soil cultivating method at first should cover petroleum-polluted soil on the soil, utilizes soil microorganisms to carry out the method for degradation of pollutant then.Its advantage is fundamentally to utilize the self-purification capacity of soil and the activity of performance soil enzyme, but causes volatile organic matter to get in the atmosphere easily, cause atmospheric pollution, and the material of difficult degradation can accumulate wherein the increase soil toxicity.The main drawback of original position mikrobe recovery technique is: all organic pollutants of can not degrading; When medium osmosis property was low, microbial growth caused latch up phenomenon easily; If not exclusively, there is the danger that produces more harmful intermediate product in degraded; The nutrition of introducing possibly cause secondary pollution; When the organic contamination substrate concentration is too low, can not satisfy microorganism growth to requirement of carbon source etc.

Summary of the invention:
The object of the invention just is the deficiency to above-mentioned prior art, provides a kind of original position remedying oil-polluted phreatic method.
The objective of the invention is to realize: comprise following order and step through following technical scheme:
A, beat the above nutrition of a bite at 8-12m place, the downstream of source of pollution 1 and add well 2; Nutrition adds the spacing 2-4m of well 2; The above observation well 3 of a bite is made at the 2-4m place, downstream that adds well 2 at nutrition, nutrition add well 2 and observation well 3 be in the plane 60 ° angular distribution;
B, nutrition add the shaft bottom of well 2 and observation well 3 on contaminated phreatic base plate;
The well casing that c, nutrition add below well 2 and observation well 3 Water tables is a floral tube;
D, add the nutraceutical mass ratio of 0.2-0.5g by the every premium on currency of the flow of polluted water in the well and nutrition is added to nutrition adds in the well 2;
E, repair degree and nutrition consumes situation through observation well 3 sampling observation petroleum pollution underground water, so that in time add nutrition.
The described nutrition of steps d is that yeast soaks powder and peptone.
The mass ratio that peptone and yeast soak powder is 2: 1.
Beneficial effect: nutrition adds well and monitor well is provided with simply, and long service life can be used for the monitoring of contaminated site for a long time; Yeast soaks powder and peptone and underground water thorough mixing, has increased the efficient that mikrobe utilizes nutritive substance, and it is simple and easy to do that nutritive substance adds process, need not other complex assemblies and mobile utility appliance, workable, with low cost; The petroleum-type that not only can be applied to light nonaqueous phase is polluted; Like gasoline, diesel oil and main pollution components benzene, toluene, ethylbenzene and YLENE etc., can also be applied to the plyability contaminated site of improvement, light nonaqueous phase and heavy nonaqueous phase petroleum pollution that heavy nonaqueous phase petroleum-type pollutes, the underground water petroleum-type of handling is in various degree polluted; Only need simple routine maintenance, operational management is convenient; Compare with existing underground water biological renovation method; Method is simple possible more, only need regularly add nutritive substance and can reach the reparation purpose, has reduced the maintaining with engineering equipment of setting up of complicated underground assembly; The treatment process construction is simple, and the processing target pollutent directly, efficiently, thoroughly; Change to underground environment is little, does not cause secondary pollution.
