Abstract
The invention relates to a leacheate and a soil remediation method, and belongs to the field of remediation of contaminated soil. The soil remediation method is characterized by comprising the following steps of providing the leacheate, wherein the leacheate comprises mixed n-butyl alcohol and tween 80; performing home position leaching on contaminated soil to be treated which is contaminated by nitrobenzene substances with the leacheate; and promoting degrading of the nitrobenzene substances by microorganisms in the contaminated soil to be treated through exogenous stimulation. According to the soil remediation method disclosed by the invention, home position leaching is combined with microorganism stimulation degrading, and through the leaching technology, high-concentration nitrobenzenepollutants can be quickly and massively removed; a surface active agent exists, so that favorable condition is created for subsequent biological remediation; aboriginal microorganisms are subjected to bio-stimulation; and after nutrient substances are added and the water ratio is regulated, low-concentration pollutants after leaching treatment are thoroughly removed, and the leacheate remained inthe soil can be effectively removed. The soil remediation method disclosed by the invention is reasonable in technology, and low in cost; the on-the-spot home position treatment conditions are completely simulated, and the workability is high; and the soil remediation method is easy to popularize and implement, and has favorable application prospects.
