Abstract

The invention discloses a restoration method of organic polluted soil. The restoration method comprises the following steps that (1) a soil restoration agent is evenly spattered onto the surface of the organic polluted soil, and deep ploughing and mixing are conducted; (2) one week later, willow seedlings 1-2 m high are planted on the soil treated in step (1), pteris vittata is interplanted in thespace of the willow seedlings; and (3) after being planted for two months, pteris vittata is pulled out and replanted for three times, and then one-year restoration is completed. The restoration method of the organic polluted soil is easy and feasible, has the outstanding removal effects on various organic pollutants such as organic pesticide residue, polychlorinated biphenyl and phenol in the organic polluted soil, the organic pesticide residue removal rate can be as high as 85.9% or above, the removal rate of polychlorinated biphenyl is 84.3% or above, and the removal rate of phenol is 86.2% or above; the raw materials are easy to get, the production cost is lowered, and the economic benefits are outstanding.

Description

technical field [0001] The invention belongs to the technical field of soil remediation, and in particular relates to a method for remediating organic-contaminated soil. Background technique [0002] The organic pollution of soil has become one of the environmental problems that are widely concerned all over the world. Organic pollutants in soil include aromatic compounds, polychlorinated organic compounds, pesticides, petroleum, etc. Most of these pollutants are insoluble, toxic, mutagenic, and carcinogenic, and have great harm to human health and ecosystems. In recent years, my country has begun to gradually pay attention to the problem of soil pollution caused by organic matter, and has carried out research on soil organic pollution remediation technology. The remediation technologies of organic contaminated soil mainly include four categories: physical remediation, chemical remediation, physicochemical remediation and biological remediation. At present, most of the var...
