摘要
由于含油污泥中老化原油含有较高的多环芳烃,以及多环芳烃的环境持久性和人体毒害性,我国现行行业标准中涉及含油污泥土地利用的石油烃类指标限值可能无法满足日益严格的固体废物环境管理要求。系统梳理了我国现行行业、地方及团体标准中上述石油烃类限值,并总结归纳了≤2%限值需要进一步完善的原因,提出了具体的改进方法,以供相关科技人员参考。
Due to the high content of polycyclic aromatic hydrocarbons(PAHs)in aged crude oil in oily sludge,as well as the environmental persistence and human toxicity of PAHs,the current industry standards in China for petroleum hydrocarbons related to land use of oily sludge may not meet the increasingly strict requirements for solid waste environmental management.This article systematically reviews the above mentioned limits for petroleum hydrocarbons in current industry,local,and group standards in China,and summarizes the reasons why the≤2%limit needs further improvement.Finally,specific improvement methods are proposed for reference by relevant scientific and technological personnel.
