Abstract

The invention discloses a remediation method for soil in a petroleum-polluted saline and alkali land. The remediation method comprises the following steps: (1) adding hawthorn, fructus aurantii immaturus and lemon leaves to water, decocting, filtering, drying the filtered materials by air, and then crushing for later use; (2) feeding soil to be remediated into a mixing tank, adding the materials crushed in step (1), and then uniformly stirring; (3) adding ermiculite powder, gypsum powder, sugarcane powder, ammonium sulfate, cerous molybdate, rice bran hemicellulose, potassium chloride, mtile powder and sodium palmitate to the mixing tank; (4) spraying petroleum degrading bacteria liquid strains and filtrate obtained in step (1), and then performing remediation culture for the soil. The remediation method is high in petroleum pollution remediation capacity and high in capacity for conditioning soil in the saline and alkali land; the time of remediation and conditioning can be reduced, and the cycle can be reduced; meanwhile, the remediation method is high in remediation and conditioning efficiency, is good in application prospect and high in value.

Description

technical field [0001] The invention belongs to the field of soil remediation, in particular to a method for remediating petroleum-contaminated saline-alkali soil. Background technique [0002] As the demand for oil continues to expand, it promotes the rapid development of oil extraction. Due to various reasons, a large amount of crude oil directly or indirectly enters the soil, thereby polluting the soil, destroying the permeability of the soil and the soil environment, affecting the growth of soil microorganisms, and also affecting the respiration of soil plant roots and the absorption of nutrients and water, endangering plants growth. [0003] Saline-alkali soil is a widely distributed soil type in the world, and it is also an important and precious soil resource. When the saline-alkali soil is used for agricultural planting, it is first necessary to mature the soil, that is, to improve the cultivation properties of the soil and increase the fertility of the soil; the s...
