Abstract

The invention provides a method for biologically repairing soil polluted by petroleum hydrocarbon compounds. The method comprises the steps of planting repairing plants in the soil and applying repairing biological agents to the soil. The repairing plants are compositions of one or more of annual ryegrass, perennial ryegrass, tall fescue grass and prairie gramineous crops. The repairing biological agents at least comprise bacterium solutions containing plant promoting bacteria, and the bacterium solutions contain plant promoting bacteria Pseudomonas cedrina UW3 and Pseudomonas putida UW4. With the method, time of soil repairing can be greatly shortened, and generally in the seriously-polluted area, the soil can be repaired to the level before pollution within three years to five years.

Description

technical field

[0001] The invention relates to the field of soil remediation, in particular to a method for bioremediating soil polluted by petroleum hydrocarbon compounds and its application. Background technique

[0002] With the development of modern industry, soil pollution has gradually become one of the global environmental problems. Especially mining, metal smelting, oil extraction and chemical industry production, the most serious soil pollution. The content of heavy metals, hydrocarbons and various toxic salts in the soil is too high, and it is difficult to eliminate them by natural decomposition for a long time.

[0003] Petroleum hydrocarbons contain a large number of harmful substances, such as benzene series, polycyclic aromatic hydrocarbons and other refractory toxic and harmful substances. Soil polluted by petroleum hydrocarbons not only has a direct toxic effect on the human body, but also leads to a reduction in food production.
