含油污泥处理残渣综合利用对土壤环境的影响
Impacts of Comprehensive Utilization of Oily Sludge Treatment Residues on Soil Environment
摘要
Abstract
The pyrolysis residue and hot-washing reclaimed soil of oily sludge from Xinjiang oilfield were taken as the research objects.The characteristic pollutants of the the treatment residues were selected as petroleum hydrocarbon(C10-C40),benzene and barium.Soil column experiments were conducted to simulate the comprehensive utilization method of direct landfill of oily sludge treatment residues under rainfall,and the concentrations of characteristic pollutants in the experimental soils under different conditions were compared.The results showed that the concentrations of petroleum hydrocarbons(C10-C40),benzene,and barium in the soils subjected to comprehensive utilization of the reduced soil did not change significantly,and the concentrations were significantly lower than the standard values.The Nemero pollution index method classified the soil as clean in terms of pollution level.The pyrolysis residue showed obvious hydrophobic and oleophobic characteristics.Under the preset precipitation regime throughout the experiment,rainwater failed to fully penetrate the residue layer,and thus the pollutants did not migrate downward with infiltrating rainwater to the underlying soil.These results confirmed that the comprehensive utilization of pyrolysis residue and reduced soil through landfill showed a negligible impact on the soil environment under the present experimental conditions.关键词
