Abstract

The invention discloses a formula and method for treating polycyclic aromatic hydrocarbon polluted soil and application. The formula for treating the polycyclic aromatic hydrocarbon polluted soil comprises the following components in parts by weight: a KMnO4 solution with the content of 10wt% and water, the ratio of the mass of the KMnO4 solution to the mass of polycyclic aromatic hydrocarbon polluted soil to be treated is 0.8: 100-1.2: 100, and by the amount of the added water, it ensures that the water content of the polycyclic aromatic hydrocarbon polluted soil to be treated is 35-45%. According to the invention, conventional potassium permanganate is used as an oxidizing agent, and is convenient to purchase, configure and use, polycyclic aromatic hydrocarbon treated by the method is oxidized into other non-toxic substances, the method is an effective and environmentally friendly polycyclic aromatic hydrocarbon polluted soil treatment method, and compared with other methods, the method is better in effect.

Description

technical field [0001] The invention belongs to the technical field of polycyclic aromatic hydrocarbon-contaminated soil treatment, and relates to a formula, a method and application of polycyclic aromatic hydrocarbon-contaminated soil treatment. Background technique [0002] Polycyclic aromatic hydrocarbons mainly refer to hydrocarbons containing two or more benzene rings in their molecules, including more than 150 compounds such as naphthalene, anthracene, phenanthrene, and pyrene. Some polycyclic aromatic hydrocarbons also contain nitrogen, sulfur and cyclopentane, and the common carcinogenic polycyclic aromatic hydrocarbons are mostly four- to six-ring condensed ring compounds. [0003] Of the 94 compounds that are carcinogenic to experimental animals listed by the International Cancer Research Center (IARC) (1976), 15 of them belong to polycyclic aromatic hydrocarbons. Since benzo[α]pyrene is the first environmental chemical carcinogen discovered, Moreover, it is very ...
