Description
Technical field
The present invention relates to gas pollution remediation technology in soil, particularly a kind of heating using microwave impressed current anode liquid drip washing strengthening Electroremediation soil system and method.
Background technology
World War II, Japan has abandoned a large amount of poisonous and harmful chemical weapons within Chinese territory, and these chemical weapons quantity are large, distribution is wide, and toxic agent is wide in variety.According to investigations, the chemical weapons that Japan abandons are distributed in 11 provinces and cities of China more than 30 point, North gets Sunwu County of Heilongjiang Province, reach Guangzhou kind Yu in the south.According to made, the quantity of chemical ammunition about 2,000,000, toxic agent about 100 tons.The overwhelming majority is embedded in barren hill, have at rivers lakebed, what also have is scattered in resident residential area.For more than half a century, Japan abandons the chemical bullet in the chemical weapons of China, and the serious corrosion in body surface, what have even leaks.Gas is the element of chemical weapons, and harmful characteristics has: toxic action is strong, and route of intoxication is many, and the duration is long, and hazard boundary is wide, and deterrent effect is large.Usually, gas can be divided into 6 classes by toxic action: several large classes such as nerve toxicant, the chemical warfare agents of genral toxicity, vesicant agent and irritant agent can be divided into.Toxic agent kind has mustard gas, phosgene, routes optimal choice (L), Clark II (DC), diphenylchloroarsine (DA) etc., they are after soil degrading, and product mainly oxygen joins the arsenicals such as two diphenylarsine, diacid arsine, phenylarsonic acid, vinyl chloride oxygen arsine and vinyl chloride arsenic acids.These arsenicals are difficult to degraded usually at occurring in nature, and sustainable decades, toxic effect, more serious to the harm of the mankind.These toxic agent and hazardous compound invade human body mainly through respiratory tract, skin, eyes etc., destroy injected organism tissue cell, cause respiratory mucosa necrosis, skin erosion, eyes stung, photophobia even blind.Therefore, in rehabilitating soil, in gas, the pollution of arsenic is most important.
The major technique of domestic and international removal gas comprises: burn, curing/stabilizing technology, flocculation-precipitation method, ferrite process bioanalysis, extraction etc.Wherein burning gas is the process by organic chemicals thermal decomposition and high-temperature oxydation.The method destruction chemical warfare agent efficiency is very high, simple to operate, economical, quick, but can discharge toxic and harmful in burning process, cause severe contamination, and soil can not recycle to environment.Ferrite process utilizes oxidant that organo-arsenic is changed into inorganic arsenic, and 3 valency arsenic are changed into 5 valency arsenic.Although reduce pollutant toxicity, easily cause secondary pollution.Flocculation-precipitation method refers to selects molysite or aluminium salt as flocculant, reacts with arsenical.The method pollutants removal rate is high, but operation has certain difficulty, and cost is higher.Phytoremediation mainly utilizes plant to restrain oneself or ultraproduct tires out the characteristic reparation of arsenic by gas contaminated soil, and by phytoremediation, the arsenic in soil is absorbed and transfers in the plant of efficient accumulation arsenic.But the method repairing efficiency is long, and not thorough to the reparation of arsenic.In sum, often kind of restorative procedure has its specific aim and pluses and minuses.
Chemical leaching is the physical transfer process utilizing leacheate pollutant to be transferred to liquid phase from solid phase of soil.Usual employing clear water or phosphate, as eluent shower soil, make pollutant and eluent form stable comple.But this shower Shift recovery is often thorough, after shower, in soil, still contain the pollutant of many pollutants and leacheate parcel.Further, the method is only applicable to the soil remediation work that area is little, pollution is heavy.Electroremediation method is the original position with the very large application potential/dystopy soil restoring technology of rising in recent years.The method is by laying electrode in soil both sides to be repaired, form DC electric field, produce potential gradient, by the effect of electromigration electro-osmosis or electrophoresis, make the pollutant in soil be moved to electrode tip at electric field action, reach the effect of enrichment pollutant, and remove pollutant.Electroremediation method on the impact of the migration of pollutant significantly, can effectively make large-area pollution gather in zonule, and institute can assist the soil after the reparation of chemical leaching method in this way.PRB reacts wall (Permeable Reactive Barrier, permeable reaction wall) as a kind of newly be the in-situ techniques of pollution administration thing, be process pollutant by the dielectric material (iron, coke, lime stone etc.) in reaction wall, may be used for removing the pollutant be enriched on electrode.And microwave heating method is as a new contaminated soil remediation technology, can not only process the organic matter (as halogenated hydrocarbons, polycyclic aromatic hydrocarbon, Polychlorinated biphenyls etc.) of volatility, half volatile, can also process the nonvolatile matters such as heavy metal.Microwave heating method is applicable to any soil types, and has the advantages such as efficient, quick, flexible operation, some useful component of little to ambient influnence, applied widely, separable recovery.Show according to the study, heating using microwave can be accelerated leacheate and to transfer the pollution the speed of thing, also can accelerate Electroremediation process intermediate ion migration velocity, play good booster action to drip washing and electro reclamation.
