Description

Device and the restorative procedure of thermal desorption co-oxidation agent repairing organic polluted soil
Technical field
The invention belongs to environmental protection technical field, particularly a kind of device and restorative procedure of thermal desorption co-oxidation agent repairing organic polluted soil.
Background technology
Since the reform and opening-up, developed rapidly along with China is industrialized, city size enlarges gradually, thereby makes urbanization process obtain unprecedented development.In the process that the city is constantly expanded to the periphery, originally be in the periphery in a large number and exist the industrial enterprise that pollutes also to become the part of urban central zone gradually; And the population of urban central zone high concentration often, these exist the industrial enterprise of pollution risk that health and Environmental security have been caused great threat.The requirement of improve city environmental quality in order to adapt to, optimizing the city function structure, China has carried out the policy of " move back two and advance three " to the transformation of urban central zone.Thus, since the nineties in 20th century, the phenomenon of large-scale industry enterprise resettlement has at first appearred in the more flourishing city of China.
Because a large amount of contaminated sites has been left in contaminating enterprises resettlements, the environmental pollution accident that causes after the resettlement and the hazardous events of health happened occasionally.In addition, since the development of petroleum industry, the contamination accident that volatility (VOCs) organic pollutions such as the gasoline that causes, diesel oil bring.Break oil storage tank seepage, the soil environment problem that gas station's resettlement etc. cause as oil pipeline.
According to the detection to the present most of organic polluted soils of China, wherein major pollutants have the total petroleum hydrocarbon class, and content can reach 1786~40167 mg/kg; Polycyclic aromatic hydrocarbon, content reach 26.10 mg/kg, surpass National Standard soil environment quality standard " third level standard value.
In the past few decades, be subjected to the restriction of multiple factors such as period of history economic technology condition and people's level of understanding, oil play is when making major contribution for country, and also brought a series of environmental problem: pollutants such as the waste water in the oil-gas mining process, waste gas, ground crude oil, waste gas drilling fluid enter environment and can impact water body, atmosphere, soil and ecological environment.Along with the extensive use of petroleum resources, the oil pollution in the environment is more and more serious.In Petroleum Production, storing, refining processing and use, also have overflowing and discharging of petroleum hydrocarbon, cause water body and the serious oil pollution of soil around oil field and the petrochemical factory.The total output of oil has 2,200,000,000 t every year approximately in the world today, and wherein 17.5 hundred million t are by the land field produces.The whole world has 8,000,000 t to enter environment every year, and China has nearly 600,000 t to enter environment every year, contaminated soil, underground water, river and ocean, annual new pollution soil 1 * 10 5T.
Up to the present, being subjected to the soil of petroleum-type contaminants and underground moisture is that dystopy reparation and original position are repaired.The dystopy reparation is contaminated soil and underground water to be transferred to more than the ground handle, and comprises in-situ processing, composting processing, pyrolysis processing, soil drip washing, bioreactor etc.The original position reparation refers to that contaminated soil underground water handles in position, is not comprised soil drip washing, biology in situ reparation and in-situ chemical reparation etc. by stirring substantially during the processing.Advantages such as the original position reparation is relatively low because of its expense, and is little to environmental perturbation, that secondary pollution is little become the soil remediation Study on Technology and put into practice main flow.
The present invention adopts is that novel thermal desorption is handled and the technology of chemical oxidizing agent Combined Treatment contaminated soil.The thermal desorption treatment technology generally refers to by direct or indirect heat exchange, with the organic pollution in the contaminated soil self decomposition, evaporation, oxidation, and separates with contaminated soil.Thermal desorption is handled incomplete pollutant adopts chemical oxidizing agent to handle.Existing a lot of strong oxidizer (as ozone, hydrogen peroxide and permanganate) that uses is handled organic matter contaminated soil and phreatic method (as surface treatment, seepage flow, filtration, desorption) at present.Wherein, permanganate is the organic strong oxidizer of a kind of processing, and the organic matter that can handle comprises: ethylbenzene, toluene, dimethylbenzene, carrene, 1,2-dichloroethanes, 1,1,1-trichloroethanes, carbon tetrachloride, chloroform, chlorobenzene, ethylene dibromide, tertbutyl ether, tetrachloro-ethylene, trichloro-ethylene, dichloroethylene, vinyl chloride etc.
Repair in position in the high-enriched organics contaminated soil process, reach safe scope in order to make organic concentration, if directly use permanganate to carry out oxidation, can generate a large amount of manganese dioxide precipitate.Though in general, manganese dioxide is a kind of naturally occurring harmless mineral matter.But in containing the soil of a large amount of organic pollutions, the amount of removing the required permanganate oxidant of organic matter is very big, and the amount of the manganese dioxide that the reaction back produces will surpass safe concentration, so can not directly use permanganate reparation generally speaking.
