Description
Technical field
The invention belongs to the auxiliary recovery technique field of oil pollution, be specifically related to the broken auxiliary underground petroleum of a kind of re-injection formula twin-well gas and pollute biology in situ repair system and auxiliary restorative procedure thereof.
Background technology
Along with the adjustment of China's energy resource structure and the fast development of transportation, the consumption of petroleum fuel and petroleum-type product increases day by day.Yet under current state, oil exploitation, transmission, refinery, and problems such as unit ubiquity seepage, volatilization such as gas station.Underground water and soil earth is caused severe contamination.Organic contamination in soil and the underground water usually has characteristics such as kind is many, content is low, harm is big, refractory reason.Oil product also contains considerable phenol and organochlorine etc. except fatty hydrocarbon and aromatic hydrocarbons.Studies show that that many organic pollutions have is carcinogenic, teratogenesis, mutagenic " three cause effect ", and health is had a strong impact on.And most organic pollutants is difficult to remove by the natural degradation process in soil and groundwater environment, and long-term existence is also accumulated.
The method of handling the underground petroleum pollution at present both at home and abroad is a lot, but different at target.The gas phase extraction technique of the vapor phase of being primarily aimed at is arranged, at the two-phase vacuum extraction technology of gas-liquid two-phase, original position/heterotopic biological recovery technique etc.Wherein the gas phase liposuction technique is mainly used in the removal to effumability short chain petroleum hydrocarbon, its negative pressure that produces by underground wellblock causes the hydro carbons volatilization, by suction hydro carbons is separated from underground water and soil then, this method has applicability preferably for the effumability hydro carbons; Two-phase vacuum draw technology is administered technology as a kind of newer underground pollution, and it is to underground free phase, and the removal of dissolving phase and volatilization phase has general applicability.Though more than two kinds of vacuum draw technology have removal effect preferably at gas phase or two-phase, and because its working strength height, energy consumption is bigger, therefore long-term control expense is also higher.This technology has very big limitation for the removal effect of generate longer-chain hydrocarbons and adsorption by soil hydro carbons in addition, especially reduce in a large number at the later stage of its production oil, gas content, there is sizable adsorbance in soil for oil gas, makes oil gas be difficult to use fully liposuction technique mutually and carries out desorption.This moment, the biological in-situ recovery technique just demonstrated its irreplaceable effect.The petroleum pollution bioremediation technology is to utilize microorganism and other biological material, and the petroleum pollution degradation that will be present in soil becomes carbon dioxide and water or is converted into the engineering of some innocuous substances.As far back as eighties of last century eighties, the bioremediation technology of petroleum pollution is just begun one's study, and use in practice gradually.And common bioremediation technology is big for pollution intensity, especially has to pollute freely that the phase existence condition is next to have a very big application limitation in a large number.Because it is consuming time longer that common biologic treating technique is handled, so be mainly used in the post-processed means on the engineering.But be limited by the underground property effect, nutriment is lower in the transfer rate in compressed soils zone, and the performance of original position microorganism recovery technique efficient is had big inhibitory action, and its remediation efficiency is had a greatly reduced quality.Therefore, the new technology of a kind of biological in-situ cheaply reparation is demanded exploitation urgently.
The broken auxiliary underground petroleum of re-injection formula twin-well gas pollutes the biology in situ repair system, as a kind of recovery technique of biology in situ efficiently, at first by the broken mode of periodicity gas, use pressure-air that underground around the well of place is shattered, with the bigger soil porosity of acquisition, thereby effectively enlarge the microbial action radius.Therefore can under the injection well condition of limited quantity, reach microorganism and nutraceutical high efficiency of transmission and efficient degradation.Especially for the dense underground zone of geological conditions, has very obvious effects.Greatly improved the degradability of petroleum pollution by increasing oxygen-supplying amount at saturated zone and unsaturation band.Ooze out bacterium liquid by re-injection in addition and can effectively utilize microorganism, and recover microbial activity by re-injection.Contain a large amount of hydro carbons and primary degradation product in oozing out mutually,, avoided the input of extra process equipment simultaneously by re-injection these hydro carbons of can effectively degrading.
