摘　　要：热脱附法在含油污泥处置领域已经普遍应用,但人们对含油污泥处理后残渣的危险特性仍认识不清,这制约了其资源化利用方法的发展。以新疆某石化企业污水处理产生的油泥经热脱附后的残渣为研究对象,通过对无机元素、半挥发性和挥发性有机物、其他有机化合物共117种物质含量进行测定,对比了土壤相关污染控制标准,系统分析了石化油泥热脱附残渣的危险特性和资源化的环境风险。结果表明:该石化油泥热脱附残渣的腐蚀性、易燃性、反应性、毒性物质含量均未超过危险废物鉴别系列标准(GB 5085—2007)的限值,不具有危险废物特性;该残渣资源化过程中需防止铜、锑、镍、氰化物、镉5种无机物和苯、石油烃、N-亚硝基二正丙胺3种有机物对农业土壤的潜在污染风险。研究结果可为石化油泥热脱附残渣资源化路径选择和污染防控提供参考。Thermal desorption method has been widely used in the field of oil sludge disposal,but the hazardous characteristics of the residue after treatment are still unclear,which restricts the development of its resource utilization methods.Taking the thermal desorption residue of oil sludge produced by sewage treatment of a petrochemical company in Xinjiang as the research object,a total of 117 substances including inorganic elements,semi-volatile and volatile organic compounds,and organic compounds were measured.The hazardous characteristics and resource utilization environmental risks of petrochemical sludge thermal desorption residues were systematically analyzed by comparing soil-related pollution control standards.The results showed that the corrosiveness,flammability,reactivity and toxic substances of the petrochemical sludge thermal desorption residue did not exceed the limits of the series of standards for hazardous waste identification(GB 5085—2007),so it was not dangerous waste characteristics.The potential pollution risks of copper,antimony,nickel,cyanide,cadmium,benzene,petroleum hydrocarbons and N-nitrosodi-n-propylamine to agricultural soil should be prevented during the recycling of the residue.The results can be used as reference for resource recycling route selection and pollution prevention and control of thermal desorption residue from petrochemical sludge.
