Abstract:The paper first introduces the chief physical properties of the chlorinated hydrocarbons and their major uses.The dechlorination of the chlorinated hydrocarbon by electrolytic iron is based on the laws of redox reactions,the adsorption of the pollutants by tiny granular activated carbon among the iron filings,the catalytic process of the tiny granular carbon,the destruction of the oxidational membrane on the iron surface by the active chloride ion and the effect of the tiny electric fields.After outlining the advances in the treatment experiments and production on the groundwater polluted by chlorinated hydrocarbon,it is concluded that the application of the iron filings corrosive cell to the in situ removal of chlorinated hydrocarbon in the aquifer is a preferential method.But before it can be widely used,many problems must be solved,especially the mechanism of the reactions must be described more clearly.Up to now, the parameters(such as the wide of the wall,the content of the iron filings) cannot be accurately determined cannot be,which needs the design of iron walls according to the specific conditions(the concentrations of the chlorinated hydrocarbons,the temperature of the groundwater,the rate of the removing chlorinated hydrocarbon and so on) in the aquifers.
Keywords:iron filings  removal  groundwater  chlorinated hydrocarbon
