Description
Technical field
The present invention relates to a kind of contaminated site soil/water body recovery technique equipment, belong to the environmental protection equipment field.
Background technology
At present, because the influence that developed rapidly by industrial or agricultural and industries such as the energy, traffic, the contaminated soil of China/groundwater level day of year benefit enlarges, and the ecosystem and human health have all been caused serious harm.Propelling along with suburbanization and counter urbanization process, a large amount of city enterprise implements resettlement, enterprise's number of China's closing down, suspending operations, merging with other plants, changing the products or moving the plants to other places in 2008 reaches 22488, these industrial waste places in process of production phenomenons such as " run, drip, leak " and various environmental accident can cause pollutant enter into the soil in place and underground water (document 1: Liao Xiaoyong etc. the urban industry contaminated site: Chinese contaminated environment is repaired the new problem in field. environmental science, 2011), form a large amount of contaminated sites, demand urgently repairing.In addition, the processes such as discharging accumulation of the adopting of a lot of mine developments, choosing, smelting, fortune and waste water and dregs all can cause a large amount of pollutants around entering into soil and underground water (document 2: Chou Rongliang etc. mine and surrounding area many metallic pollutions soil remediation progress. agricultural environment science journal, 2009,28 (6): 1085-1091); The farmland is dirty irritate the pollution problem that is caused also have in recent years a lot of reports (document 3: Chen Cuicui etc. Dunhua irrigated area, Taiyuan City heavy metal pollution of soil feature and evaluation. agricultural environment science journal, 2010,29 (supplementary issues): 069-073); The percolate and the solid waste gas of a lot of refuse landfills also can pollute surrounding soil and underground water; The leakage of gas station's gasoline etc. and the discharging of oil gas also make its peripheral soil and underground water also have pollution in various degree.Therefore, contaminated soil of China and underground water reparation have vast market demand and prospect.
At present, have a lot, comprise biological restoration, physics reparation and chemical repair method etc. at the method for contaminated soil/phreatic reparation.Biological renovation method mainly is the pollutant that utilizes in plant or microorganism absorption or the degraded soil/underground water; Physical method comprises the thermal desorption technology, soil aeration and gas phase extraction technique etc., thermal desorption is to make wherein organic pollution and special metal elements vaporization be converted into gas by heating soil, by special device pernicious gas is carried out the restorative procedure of harmless treatment again, soil aeration and gas phase extraction technique mainly are the methods that feeds fresh air and utilize extraction system that gas is extracted out by in contaminated soil/water body, discharge gaseous contaminant, reach the purpose of purification, better for the treatment effect of volatile organic contaminant; Chemical repair method comprises chemical leaching technology and chemical oxidation/reduction technique etc., chemical oxidation/reduction technique then is meant oxidant/reducing agent is injected pollution medium, make the pollutant in soil or the underground water destroyed within a short period of time by oxidation/reduction reaction, be degraded into nontoxic or endanger less material, can be applicable to petroleum like hydrocarbon, benzene, phenols, MTBE, chloro-carbon solvent, polycyclic aromatic hydrocarbon, the reparation of organic pollutions such as agricultural chemicals and some heavy metals that appraise at the current rate, the drip washing technology is a technology of utilizing surfactant or cosolvent to come wash-out or desorption pollutant, can be used for the reparation of organic matter or heavy-metal contaminated soil and water body.
When carrying out place original position reparation or the reparation of fairly large dystopy, need in contaminated soil or water body, add a large amount of preparation for repairing and (comprise chemical preparation for repairing, eluent and microorganism preparation for repairing etc.), but inject equipment owing to lack corresponding preparation for repairing at present, cause the enforcement of this class reparation also to have bigger difficulty.Mention in the Chinese patent application 200910061186 and utilize original position microwave recovery technique to administer soil pollution, just at topsoil.Mention the deoxidization, degradation of organic pollution in the acceleration soil such as utilizing Zero-valent Iron simple substance in the Chinese patent 200710026561.9, also be to draw the original position reparation that this method is applicable to the severe organic contaminated soil by the post experimental simulation, do not mention contaminated site, how preparation for repairing such as Zero-valent Iron are injected surrounding medium to be repaired in reality.Mention in contaminated soil and underground water in the Chinese patent 200710069637.6 and inject liquor potassic permanganate, hold back explosion pollution thing in district and the Polluted area, but also do not introduce concrete injection equipment and method by chemical oxide removal.Aspect the dystopy improvement of deep soil/phreatic original position reparation and large-scale contaminated soil/water body, how development and utilization effective for repairing equipment (comprises microorganism formulation with preparation for repairing, the chemistry preparation for repairing, eluents etc.) being added in the deep layer soil body/water body, is a key issue that needs solution.
The contaminated site prosthetic appliance of China comprises prosthetic appliances such as SOIL GAS is carried, chemical oxidation, thermal desorption, drip washing at present, rests on exploitation of scientific research equipment or experimental prototype pilot scale stage more, and the commercial application of prosthetic appliance seldom.Countries such as America and Europe have developed a lot of advanced persons' prosthetic appliance, but price is extremely expensive, and might not be adapted at China's application.The equipment of this patent invention can solve the problem of injecting preparation for repairing in original position or the dystopy repair process in deep layer contaminated soil/water body effectively, can improve remediation efficiency, have crucial meaning soil/further developing of field of underground water reparation for promoting China.
